1. Dyson Pure Cool Link Tower Air Purifier TP03
This premium Air Purifier from Dyson is evidently one of the best in the market. It has impressive purification power and comes with a few interesting benefits that we’ll get to in a moment.
Firstly, let’s talk about the most vital aspect first- about how well it can purify the air in a room. This tower air purifier boasts the ability to remove as much as 99.95% particles in the air. That’s true, as it can, in fact, clean out all kinds of harmful pollutants in the air like dust, pollen, bacteria, lint, moulds and other toxic gasses. Even impurities as tiny as 0.1 microns get trapped into the air purifier’s filters.
Another thing that sets this air purifier apart from others is its low face velocity. Standard air purifiers have a higher face velocity. This causes air to get forced through the filters, and sometimes the air might carry the smallest pollutants (ones as little as 0.1 microns) into the room again. Unlike these air purifiers, Dyson purifiers have a significantly lower face velocity, which stops most of the ultrafine pollutants from passing through the filter.
This Dyson air purifier also has some intelligent features. It comes with a smartphone app, along with additional sensors. It can monitor your indoor air quality, purifying the air when needed and providing you data about the air quality live on your app. The app can also notify you if the filter needs replacement, so you can always keep the purifier running at full performance.
Besides, you also get some of the best combinations of purification methods with this filter. There is a 360° Glass HEPA Filter, which works in conjunction with Tris-coated Activated Carbon to make sure the air in your room is the cleanest at all times. Moreover, the Oscillation feature and the Air Multiplier Technology will make sure the air gets adequately delivered into the room.
Overall, we can say that this purifier is an excellent choice, and to back up its claims, the purifier comes with a certificate from the Asthma and Allergy Foundation of America. Plus, the purifier doesn’t use any regular fans. Instead, it’s Air Multiplier does the work, creating a steady and powerful stream of air. The air production is so effective that you can even use it as a regular fan.
2. Coway White AP-1512HH Mighty Air Purifier
Coway’s purifier is one of the best air purifiers in India that can provide the finest level of purification. It comes with a host of effective mechanisms, and it even manages to look good without compromising any of its performance. Let’s take a look at some of its best features.

In fact, this device has even received an award for the brilliant design.
Speaking of performance, this air purifier is also one of the best air purifiers when it comes to cleaning the air. It has multiple filters, which allow it to achieve the feat. When the purifier sucks in air; the air gets passed through a pre-filter where common impurities like dust and dirt are taken out.
Afterwards, the air goes into the Urethane Carbon Filter, where it’s cleaned of any foul odour, harmful gases, VOC and even Formaldehyde. There’s also a True HEPA filter which takes out the PM 2.5 Particles, Allergens and Bacteria in the air before the air is finally pushed out, healthy and purified.
For your convenience, the device also comes with an auto mode, which uses smart sensors to get a reading of the pollution in the air and adjust the purifier’s speed accordingly. Besides, the machine also gives you an idea about the quality of the air by using intuitive colours. There’s also an additional turbo mode that you can use to quickly clean up the air in your room if you need to do so.
Even more, this air purifier needs much less maintenance. That’s because both the HEPA and Carbon filters are of high quality, so unlike standard air purifiers, you don’t have to spend as much money to keep these expensive filters running smoothly.
Overall, it’s an impressive air purifier- it doesn’t have a lot of gimmicks, and it’s still reliable when it comes to cleaning the air in your room. Besides, our surveys show that this air purifier has some of the best after-sales services out there.

4. Philips High Efficiency Air Purifier AC2887
Philips is well known among India and many other countries for its excellent home products. This high-efficiency air purifier is no less and even comes with dedicated air purification modes to help you clean out certain impurities.
The actual air purification performance is no concern with this purifier. That’s because it uses an innovative aerodynamic design, alongside a powerful NanoProtect Filter and VitaShield IPS technology. With the combination, it can even get rid of the tiniest particles, including ones as small as 20m.
Gas removal is efficient as well; it can get reduce gases like Formaldehyde, TVOC and Odour. Bacteria isn’t an issue either, as it can remove nearly all of the harmful ones.
Although the device itself is a bit bulky, that’s because of all the content it comes packed with. It still fits in perfectly with most spaces. When you need to stay focused, you won’t even notice it’s there. The purifier runs quietly when it’s used with its lower settings. Additionally, you can also dim or turn off the lights on the UI and AQI if it’s too distracting to you.
Moving on- it does come with a few interesting extra features. You get three smart presets, which are Allergen, Bacteria and Virus modes. These modes can give you an extra edge. For instance, if someone at home has respiratory issues, you can take advantage of the Allergens mode and keep the air healthy for them. In fact, the purifier can even do it for you. It uses Aerosense Technology, which consists of a high-grade sensor. It can even detect particles that are smaller than PM 2.5. It’ll adjust itself to the right settings based on the air condition, so you don’t have to.
To top it off, it also comes with filter replacement alerts, so you don’t risk your health when the purifier isn’t able to work correctly.
5. Mi Air Purifier 3 with True HEPA Filter
This Mi Air Purifier 3 sets itself out from any standard purifier with its impressive cleaning power. Mi has excellent design quality, and this one has all that, along with a powerful filtration system to make sure it gives you pure air for a long time.
Let’s begin with its air cleaning capacities first. This air purifier can cover a medium-size room just fine, and clean up the air in it thoroughly. The coverage area is about 484 square feet. It doesn’t take long for it to purify the air either, the CADR of this purifier is 380 m³/h, which is higher than most of the other air purifiers in the market.
Moreover, you don’t need to worry about any of the particles still being left in the air, as the filter uses a True HEPA filter.

The UI of the app is clean, and the best thing about the purifier’s wireless capabilities is that it can be controlled with Alexa and Google Assistant.
6. Philips AC1215/20 Air purifier with 4-stage filtration
The AC1215/20 air purifier from Philips can remove over 99.97% of pollutants from the air in a room. It has the hardware to back up such claims as well. Let’s take a look at its power and all the other features it has to offer.
Unlike most air purifiers that use a two or three-step filtration system, this one can offer you four.

Better yet, the filtration system in this purifier is completely Ozone-free, unlike other types of air purifiers that let out Ozone in copious amounts. So, you can expect natural air filtration with no risk to your health. It even has a night mode to help you sleep better.
This air purifier also has easy to read air quality indicators. You’ll get real-time feedback from the indicator, and you can adjust the settings and modes to your needs. To top things off, there are no compromises; you even get a Healthy Air Protect alert letting you know about when the filters are dirty, and you need to change them. There’s even a child lock, which isn’t something you see in most air purifiers.
7. Sharp Air Purifier for Homes & Offices FP-F40E-W
The populace has a lot of admiration for Sharp’s air purifiers, because of their efficient and unique technologies. The FP-F40E-W is one of these purifiers, and you will find it to be a very satisfactory purchase.
Let’s talk about the Plasmacluster Technology first. It’s the most significant feature that makes the purifier good enough to be one of the best purifiers around. This is how the technology works; The purifier first lets out Plasmacluster Ions into the air, which breaks down the microbes in it. Afterwards, these ions return to the air as water.
That’s only one purification method though- the air purifier works with a mix of two methods. The Plasmacluster Technology works with passive filters, which are some of the best. These filters consist of powerful HEPA and Carbon Filters, alongside Pre-Filters.
To enhance the efficiency of the purification, there’s a HAZE Mode, which is ideal for places with high pollution levels. The mode releases Plasmacluster Ions of high-density with a different fan speed, getting rid of most of the pollutants.
Airflow is impressive as well. This Sharp air purifier uses 20° Airflow, which allows it to clean the air in the room correctly. It can even pick up dust from the lowest levels of the room, while also reducing the amount of static electricity in the room. As a result, you get better cleaning.
There are certain quality of life additions as well. The Dust and Odour are extremely sensitive, and they give you readings of both. Besides, there are also colour LED lights that glow in different colours to provide you with an idea of the general pollution level. The look of the air purifier also adds a little bit of extra charm to your room.
8. Mi Air Purifier 2C with True HEPA Filter
This MI Air Purifier is one of the best air purifiers in India. It has a powerful filter, it’s inexpensive and easy to handle. If you’re a bit tight on budget but still want a high-quality air purifier, this one is a great choice.
Despite how wallet-friendly this air purifier is, it still works perfectly for small and medium-size rooms. In fact, this purifier is explicitly designed with India in mind. Hence, you can still expect excellent air purification. Let’s talk a little bit about what purification process the purifier uses.
For a start, it uses Dual Filtration Technology, which isn’t all that common in air purifiers in the same price range. The primary filter will get rid of larger particles, after which the True HEPA filter finishes the rest of the pollutants, trapping 99.97% of microbes smaller than 0.3 microns. As the HEPA filter is a true one, the purification will be consistent, and you can always rely on the purifier to keep you healthy.
The 360° suction and tower design of the purifier enables it to take in the air quickly, and pump it back out. Combined with the CADR of 350m³/h, and with the clean air reaching as much as 452 square feet, it can purify the room air in more or less 10 minutes.
You also get an Air Quality indicator that has three colours, and the best thing about it is that it includes the same real-time information display that most expensive and new air purifiers do. Another small but great addition this device has over its competitors is the easy filter change mechanism, which can be used to switch the filter with a new one in less than 10 seconds.
9. Blue Star BS-AP490LAN 915 CMH 88-Watt Air Purifier
Blue Star is good with purification technologies. They’ve made some of the best water purifiers in the market. Likewise, they have the same level of expertise when it comes to air purifiers.
This air purifier comes equipped to deal with every type of air pollutants including chemical, physical and microbiological ones. The filtration process is quite extensive. It has filters like high-density aluminium filters, cold catalyst filters, formaldehyde filters and even a True HEPA filter.
Each filter is specialised for a different pollutant, for instance, the pre-filter is good for dust particles, the cold catalyst and formaldehyde filters are good for odours, and the True HEPA one can keep fine particles like PM 2.5 and PM 10 away. So, you can get enormous health benefits with this air purifier. Besides, there’s even an additional microbe sterilisation technology which works to keep airborne microbes and dangerous bacteria like E.coli away.
Moving on, there’s also consistency to the purification. It can clean up the air in your room fast and keep cleaning it continuously. It can cover as much as 800 square feet of area, which is better than most standard air purifiers. Moreover, the air gets delivered to that distance relatively fast as well- because the purifier has a CADR of 915 CMH.
The air purifier is smart as well. It uses SensAir Technology to intelligently sense the air around the device as well. The sensor also takes odours and PM 2.5 into account and gives you individual readings. You don’t have to do a lot of work either; the technology can adjust the machine’s speed and performance based on the readings of the air quality.
That’s not everything the purifier offers though. Other notable functions include a Silent mode, separate filter clean and filter change alarms, a timer and even a child lock.
10. Honeywell Air Touch A5 53-Watt Room Air Purifier
Honeywell has just recently started making air purifiers that score high both among experts and the general populace. This classy purifier comes with the most eye-catching of looks, and with powerful performance.
Let’s begin with the actual purification process first. The purifier uses a 3-stage advanced filtration system, where the best combination of filters is used. There’s a pre-filter that get rid of dust, hair and pet dander. After it, there’s a HEPA filter which can effectively remove bacteria, viruses, VOC and PM 2.5 particles from the air. There’s also an activated carbon filter at the end to get rid of harmful gasses and foul odours.
Air intake and delivery are at the highest, as the purifier uses 3D airflow technology and pulls in air through both its sides and its bottom before blowing the air out at a CADR of 250 m³/h. This high CADR can clean up a room as big as 323 square feet. You’ll get an amazing reach, and the pure air can reach even the farthest ends of the room.
Besides, maintenance in this purifier also needs little effort. The pre-filter is washable, and the other filters can last as long as 9 months with an average 8 hour of usage. Speaking of usage, even if you use the purifier for a long while, it won’t be heavy on your electricity bills. This Honeywell purifier has very little power consumption.
Another unique feature that doesn’t come with some air purifiers is the Child Lock feature, which effectively keeps kids safe. You can rest assured about the safety of your health too, as the Indian Medical Academy For Preventive Health approves the purifier for Indian homes. Moreover, it’s also certified by ECARF.
Best Air Purifiers in India – Buying Guide
Air Purifiers are relatively recent in India, and the technologies they use are advancing day by day. So, we’ve added this comprehensive buying guide to tell you everything you need to know to buy the best air purifiers in India that fits your needs.
What is an Air Purifier?
First off, let’s touch upon the basics for a moment. Air Purifiers are small devices or HVAC attachments which remove impurities in the air and improve the indoor air quality. These purifiers are great for people suffering respiratory problems, or for maintaining good health.
Why Do You Need an Air Purifier?
An air purifier can give you all manner of benefits. For a start, the airflow in your home is limited, due to the walls. As a result, a lot of contaminants can accumulate inside the air of your room. An air purifier can make up for the lack of airflow.
The purification process is extensive, and also gets rid of unpleasant odours that are made by regular activities. So, you get to be healthy and extra comfortable. The level of purification is also especially good for those with respiratory issues.
Let’s take a look at some of the pollutants air purifiers can remove from the air.
1. Airborne Particles
General airborne particles like dust, pollen and lint can be harmful to health. Air purifiers keep all these from floating in the air, allowing you to breathe more easily.
2. Tobacco Smoke
Smoking is common in a lot of households, and if you live with someone who smokes tobacco, then the air might be contaminated by the smell of the tobacco. You might find such circumstances very irritating. Not only that, but you’ll also be exposed to the same diseases that the smoker has chances of getting, due to inhaling the smoke.
Tobacco smoke produced by someone through exhales called secondhand smoke, and it can be harmful to health. The purifier can get rid of the smell and prevent the effects of secondhand smoking.
3. Household Gases
You might not realise it, but 90% of poison exposures can occur in your own home. For a start, the cleansers and manufactured products in your home let out their own toxic gases. The solvents you use at home can also produce gases. Such solvents include paint, pesticides, air fresheners, aerosols, bleach and so on. These products don’t cause a lot of harm on their own, and some only cause small cases of irritation.
However, when put together in the same house and with prolonged exposure to them, you run the risk of health problems with your lungs, kidney and various parts of your nervous system.
Another major household gas that can cause you a lot of problems is Carbon Monoxide. It is a colourless, odourless gas which can bother the circulation of oxygen throughout the body. This gas is a result of your stoves, heaters and generators. If exposed to it long enough, it can cause extreme fatigue, headache, dizziness along with nausea. The effects will only worsen after that point, leading you to experience bouts of unconsciousness or end up hospitalised.
4. Excess Moisture
When you cook, bathe, wash dishes or dry your clothes, you add moisture to the air. Some of the heaters you use can also increase the moisture levels. Even more, if you don’t have insulation on the surfaces of your home, then during months like winter, droplets can gather upon those surfaces.
As a consequence, the excess moisture can lead to rot around portions of your home, along with peeling paints and even growths of mould. A lot of the best air purifiers come with dehumidifiers, which can prevent both the excess moisture and the mould growth, letting you be more comfortable and keep you healthy.
5. Volatile Organic Compounds
VOCs are another kind of gasses given off by things in your home. Regular building materials at your homes such as plywood, particleboards and the glues you use let out a common VOC, called Formaldehyde. You’ve probably heard of it before; it’s a harmful gas that’s without any colour but smells acrid and bitter.
Other regular activities that result in the creation of VOCs include burning fuels like gas and wood. The burning of Tobacco products creates VOCs as well. These VOCs can cause multiple irritations within your body, along with dizziness and nausea. They can even lead to forms of damage on your kidney, liver or your nervous system. Moreover, these VOCs are also a threat to the metal appliances in your home, as salts, which can cause corrosion to metal, are also VOCs. As they’re a gas, they primarily travel through the air, and air purifiers are the best at cleaning out said air.
6. Particles in the air
There are certain tiny particles in the air, which are less than or equal to a mere two and one-half microns of width. These particles have specific sizes, which once consumed, are hazardous to health. You’ve probably seen “PM2.5” or “PM10” on labels or descriptions of air-related products. These terms are used to describe the same kind of particles we’ve mentioned earlier.
How Does an Air Purifier Work?
You might wonder how an air purifier can work through such tiny particles and clean the air up. Well, we’ll provide you with a comprehensive description of how air purifiers actually work.
For a start, an air purifier does the purification with two main components- the fan and the filter. The fan is what the purifier uses to pull in the air and release it after it’s purified. Once it’s on, the purifier pulls in the air before passing it through the filter, where pollutants and impurities are removed. Afterwards, the clean air is then pushed back out into the surroundings.
The filters are what do the purification- they’re generally made up of fibre, mesh or paper. Some filters come with a single filter, while some come with extras. Something you should note about the filters is that regardless of what they’re made of, they need to be cleaned often to keep the purifier running at peak performance. They might need to be replaced a few times as well. So, when you’re about to purchase an air purifier, you should also factor in the replacement costs.
Advantages of using an Air Purifier
High-quality air purifiers can give you a large number of benefits, and once you know all of them, you’ll realise that they’re close to essential. Some of these benefits include:
Different Purifying Techniques in Air Purifier
Air purifiers use multiple advanced and effective methods to purify the air. Here’s the kind of techniques the majority of the purifiers use.
1. HEPA Filter
HEPA Filters are the best method to purify the air. They provide the highest level of filtration air purifiers can offer. Something you should keep in mind if you get a purifier with HEPA filters is that you have to make sure it’s a true HEPA filter. Some purifiers use misleading terms like “HEPA-like” or “HEPA-type” to sell you filters that don’t work as well as an actual HEPA Filter.
2. Activated Carbon Filter
Activated Carbon Filters are good with reducing odours from the air. They work through a unique type of activated carbon, which has millions of tiny absorbing pores. These pores allow the purifier to trap gases, odours and fumes by creating a larger surface area.
3. UV Lamp
If you want to make sure that the air purifier you get cleans out bacteria especially well, then you can go for one with a UV Lamp. According to the California Air Resource Board, a 20W light bulb can kill bacteria, microbes and germs effortlessly. You don’t have to worry about any side effects to your living environment either, as these lamps don’t let out any ozone byproducts.
However, one thing to note is that UV Lamps work the best when combined with HEPA or Activated Carbon filters. While UV Lamps are great at filtering out germs, they’re not so great at dealing with other pollutants. So, it would be best if you got a purifier that has a UV Lamp and an additional filter, as microbes can hide with the pollutants and go past the filter.
4. Ion Generators
Air purifiers with Ion Generators are normally called Ionic Air Purifiers or Ionizers. These air purifiers use charged ions, letting them out into the air where they attach themselves to pollutants in the air. As a result, the particles become attracted to one another, joining up together to become large and heavy. This increase in size and weigh causes them to stop floating in the air. Instead, they end up getting stuck to surfaces like walls, floor and furniture. Sometimes, some particles still do remain in the air.
As you can likely see at this point, this method is rather inefficient as it doesn’t really trap or neutralise any pollutants. You have to deal with the accumulated particles stuck to the various places again when you’re dusting or vacuuming your home. There’s a chance you’ll still end up inhaling them.
5. Ozone Generators
The last type is the Ozone Air Purifiers or the Ozone Generators. We don’t recommend getting an air purifier with these, as these generators produce high levels of Ozone which is harmful to health.
However, to make sure you don’t get misinformed by a salesman, we’ll include all the pros and cons of this type of purifier and the limited situations it can be used for. These purifiers break oxygen molecules into two oxygen atoms.
Afterwards, the resulting atoms recombine to form molecules with three oxygen atoms. This results in the production of Ozone, which is very reactive and can change the composition of nearby molecules, by adding in extra oxygen atoms.
Things to consider before buying the best air purifiers in India
Now that you know what to focus on first before looking at a specific model, you can go ahead and understand the technical specifications, ratings and additional features. As you can see, there are a lot of air purifier types, and as such, there are a lot of specifications you have to look at. Once you’ve made sure all your needs are met, you can go ahead and get yourself the best air purifier in India.
1. Room Size
The amount of air in a room depends on its size. Hence, you need to get an air purifier that’s adequate for the room’s size. Larger rooms need large purifiers, and likewise, smaller rooms need small ones.
There are air purifiers of various sizes, from small to large. You can check the coverage area specified on the purifiers product description or package, and compare it with your room size. To make sure all the air in your room is purified, you need to make sure that the model has a coverage area a little more than the size of your room.
The coverage area will be in square feet, and you can figure out your room’s measurement in the same unit by multiplying its length and width. If you’re going to get an air purifier for several rooms, then make sure that the coverage area of the purifier is more than the sum of the size of all rooms.
2. CADR ratings
CADR or Clean Air Delivery is the cubic meter of air delivered within an hour, Although, it can also be the cubic feet of air delivered in an hour. The CADR rating helps you get an estimation of how well the air purifier works when it comes to purifying the air in a room of specific size.
Understanding CADR rating is vital, as doing so helps you figure out the best choice when you’re looking at multiple air purifiers. However, every air purifier doesn’t have a CADR rating, though. The only air purifiers that have them are those who took part in the Association of Home Appliance Manufacturers (AHAM) test.
Here’s a small list about what to expect from certain CADR ratings:
|More than 250||Excellent|
|180- 250||Very good|
|120 - 180||Good|
|60 - 120||Decent|
3. ACH rating
The ACH (Air Changes Per Hour) refers to the number of times an air purifier can exchange the air in a room, in an hour. Such as- if the ACH rating of the purifier is 4x, then it means that the entire air volume is exchanged four times an hour. In fact, ACH ratings aren’t talked about that often. However, understanding them will get you one step closer to getting the best air purifier for yourself.
When you’re comparing between multiple models of air purifiers, then looking at the ACH rating will give you an idea about which purifier is faster when it comes to exchanging air within the room. It would help if you got a purifier with a higher rating, as the more air the purifier can exchange within the room, the cleaner and fresher the resulting air will be.
We advise not going under 4x, as anything below will have a significant performance gap between the higher counterparts. As we’ve said before, the ACH rating isn’t bought up much, so most manufacturers usually don’t write it on the specification list. Still, you can easily calculate the ACH rating yourself.
To begin with, you need to know the purifier’s CADR rating and its coverage area. The formula goes like this:
ACH rating = Air changes in an hour / Room volume (area x height)
So, take for instance, that the CADR of an air purifier is 360 m³/hour. Now, let’s imagine the room is 310 sq. ft., with the height being 10 ft.
Although, most of the air purifiers in the Indian market use m³/hr for the CADR. As such, you have to convert it into cubic feet per minute first. You can do so by multiplying the value with 0.588, since 1 m³/hour is 0.588 ft³/min.
With that in mind, the cubic feet per minute (CFM) of CADR would be = 360 x 0.588 = 211.68 CFM
After figuring out the CFM, you can find out how much cubic feet of air the purifier can produce in an hour by multiplying the resultant CFM value with 60.
So, Air change in an hour = 211.68 (CADR in CFM) x 60 (mins) = 12,700.8
Consider the room volume = 3100 (310 x 10)
Hence, the ACH rating will be = 12,700.8 (Air change in an hour) / 3100 (Room volume) = 4,09
Air purifiers are generally bulky and take up quite a bit of space. If you want to be able to use it in different rooms, then you should likely get one that’s light. Some offer enhanced mobility with caster wheels. They’re sized so that they fit in easily wherever you put them.
Just make sure that wherever you set the purifier in, it gets at least 18 inches of space so nothing can bother the airflow. That’s because air purifiers usually bring in the air through their sides, so putting them between objects or against walls might make them less efficient.
Certain air purifiers tend to create a bit of noise, so if you want to keep any near you while you sleep, then you need to check the noise emission levels of the device.
Some make a considerable amount of noise, like purifiers with HEPA or Carbon filters. These need to use fans to make the airflow properly. However, the noise levels can be managed if you want to use purifiers with such filters- the best air purifiers allow you control over the fan speed. So, you can put the speed to the minimum.
6. Power consumption
Air purifiers use up electricity as long as they’re turned on, so you might have to check up on the purifier’s energy consumption before buying it. The star rating on the purifier and the area it will cover is what’s going to determine the number of bills you’ll have to pay for using the air purifier.
7. Maintenance cost
Maintenance is a must if you want to have a working purifier that cleans the air efficiently and lasts a long time. Before you get an air purifier, you can estimate some of the maintenance costs and see if you can keep it running for a while without any loss in efficiency.
The best air purifiers in India usually come with HEPA or Carbon Filters, which you have to replace often. They can capture even the smallest of pollutants, so they clog up sometimes. You must make sure that you can replace these filters, as the purifier would be practically useless without them, and you’d just be wasting your electricity when running the air purifier. Another thing to note is that these filters only last one year or so.
Ionic or Ozone generators generally don’t need as much maintenance, and they don’t need replacements. However, they are relatively inefficient, though.
8. Advanced features
A few of the best air purifiers come with extra features which make life easier. Do keep in mind, though, that the price of the purifier also gets higher with each feature. Let’s talk about some of the most notable features.
It’s always a good thing to buy a product from a known and trustworthy brand. Many brands can tell you that their purifiers are the best air purifiers on the market, but that doesn’t always stand true. Less known brands would just use that for marketing. There might be a considerable upside of the air purifier they offer, but there’s likely an equally large downside hidden in the device somewhere.
Reputed brands usually have the money to back up their claims and provide you with purifiers of significantly better quality and excellent after-sale service.
Best Air Purifiers in India – Frequently Asked Questions
1. How often do air purifier filters need replacement?
Well, you should always replace your filters at the end of every year. Though, if the air quality in your area is poor or if it’s heavily industrialised, then you might need to replace these filters more often. Both the quality of the outdoor air, and in turn, the indoor air, can shorten the amount of time an air filter can go without a replacement.
2. What kind of air purifier works the best?
To have an air purifier that gives you excellent performance, you need to go for one with a multi-stage purification process. The purifiers which clean the air the best are those with at least a 3-stage purification. An air purifier which uses a pre-filter, HEPA filter and activated carbon filter is an ideal choice. Besides, if the purifier also uses a UV filtration method, the better.
3. How does an air purifier compliment an AC?
For the most part, air conditioners tend to recirculate air in a room, without bringing in outside air. So there won’t be a lot of fresh air around the room, and the impurities would eventually accumulate. Having an air purifier allows the air produced by the AC to be actively cleaned. Such a combo works even better with an air conditioner comes with additional filters.
4. Is it alright if the purifier runs continuously for prolonged amounts of time?
Yes, it’s okay if you keep the air purifier for a whole day or night, to purify the air in the room. However, that would make the air purifier gather impurities faster and lessen its efficiency. So, you have to be ready to clean the filters more frequently if you want to keep the air purifier on all the time.
5. Do air purifiers cool up the room’s air?
No, air purifiers don’t cool up the air- they only purify it.
6. Can dirty filters be harmful to health?
Sometimes, the trapped bacteria on the filter will start feeding on the other pollutants stuck to that filter. These bacteria have a possibility of being blown out back into the room eventually. Spores inside the filters might also float back into the air. If such things happen, you may end up sick, so it’s essential to clean the filters as much as possible.
