Do you want to know the best air purifier in India? If you do, then you are in the right place. Here, I have reviewed the top 5 air purifiers and listed their features, pros, and cons.
I understand it can be difficult to find the best air purifier in India. As there are many brands and models to choose from and it’s hard to know which one is the best for your needs.
A good place to start is with what you need an air purifier for. If you want one for allergies or asthma, or if you have pets then a HEPA filter will be more important than if you just want one for a cleaner environment.
Additionally, before we can choose an air purifier, we need to consider a few factors. These include the size of our room, the level of pollution in our area, and the type of pollutants that we are most concerned about.
Hence, let’s go over everything in detail so that you can make the right choice
How does an air purifier work?
In response to the most common questions, here is a quick answer:
To clean the air, the air purifier uses mechanical, ionic, electrostatic, or hybrid filtration. During this process, air purifiers draw polluted air through filters. After that, the air is recirculated back into the room.
Moreover, the air purifier absorbs dust, pollutants, and odors to clean the air inside your room. This allows you to sleep soundly.
As we continue, let’s examine the most important factors to consider when choosing an air purifier.
The basics of air purifiers
Let’s start with a few things that you should know before choosing an air purifier. The purifiers work on different technologies and you may be unfamiliar with some concepts.
So, let’s take a look at it first,
1. Levels and Types of filter
a) Pre-filter
Pre-filter eliminates larger particles before the next stage of filtration. Such as foam, pet hair, non-woven polyester, etc.
b) High-Efficiency Particulate Air (True HEPA)
The HEPA filter is effective at cleaning allergens such as pollen, animal dander, mold spores, and dust from the air. 99.9% of all particles can be removed by HEPA filters, even those as small as 0.3 microns.
However, it is necessary to change the HEPA air purifier filter on a regular basis. Every six to twelve months, HEPA should be replaced. In general, the larger the HEPA filter, the more particles it can remove. Additionally, performance is determined by the filter’s size, material, and construction.
As for limitations, HEPA filters cannot reduce gases or odors. Also, it can be costly to maintain them.
c) Activated carbon filters
They are used along with other filters. Smoke, chemicals, food smells, and fumes are neutralized by activated carbon/charcoal filters.
However, they aren’t particularly effective against formaldehyde, ammonia, or nitrogen oxide. Since activated carbon filters won’t catch particles, many air purifiers will have an activated carbon filter along with a mechanical filter (HEPA).
Also, filters made from activated carbon get saturated faster than mechanical filters. Hence, they need to be replaced more often – every three months instead of every six to twelve months.
d) Antibacterial and Germicidal filters
The filters help to eliminate harmful bacteria and germs.
e) UV Filter
Combined with HEPA filters, UV filters ensure that your air is sterile. To minimize airborne infections, this filter is generally used in hospitals, kitchens, laboratories, and daycare schools.
f) Charged Media Filters
With charged media filters, particles as small as 0.1 microns can be filtered through particle filtration and an electrostatic charge filter. To keep the system working properly, this filter needs to be replaced as well.
g) Photocatalytic Oxidation (PCO) filter
During the filtration process, a PCO filter uses a titanium dioxide-coated metal plate and ultraviolet light to oxidize and break down chemicals.
h) Ozone generator
Ozone, a molecule produced by these machines, can react with certain pollutants and alter their chemical composition. Air purifiers of this type can result in dangerous indoor air quality, which is why it is not recommended.
While ozone generator manufacturers claim their devices emit safe levels of ozone, tests in the past found that even at low settings, some generators exceeded the FDA’s limit of 0.05 parts per million. In addition, the EPA reviewed studies that found that low levels of ozone do not effectively destroy indoor pollutants.
Moreover, ozone can cause throat irritation, coughing, chest pain, and inflammation of lung tissue, as well as decrease lung function. There is also a possibility that ozone exposure can worsen asthma, emphysema, and bronchitis.
i) Electrostatic precipators and ionizers
These electronic models charge up air particles, which attract plates on the machine or nearby surfaces like magnets. As electronic air purifiers can produce ozone, it is not recommended.
j) Ultraviolet germicidal irradiation (UVGI)
UV lamps are claimed to kill airborne viruses, bacteria, and fungal spores. However, certain bacteria and mold spores might be missed as they are resistant to UV radiation.
For UVGI air purifiers to work, the UV light must be powerful and be exposed long enough—minutes to hours rather than seconds as in most UVGI models.
2. Air Change Rate of an Air Purifier
The ACH (Air change per hour rate) of an air purifier indicates exactly how many times the air from the room is filtered in a single hour.
3. CADR Ratings
The CADR is a number that reflects how fast an air purifier can remove 100% of pollutants from a cubic foot of air in a minute. Pollutants such as smoke, dust, or, pollen. Higher ratings mean a purifier is able to clean a larger space or change the air more frequently per hour.
4. Area/room-based air purifier
When choosing an air purifier, it is important to consider the size of your room. A bigger space will require a larger air purifier, so choose one that can cover a space that is 20-40% larger than the room for best results.
It is also important to consider the type of room when choosing an air purifier. Additionally, make sure that the air purifier you choose is quiet enough to allow you to sleep peacefully.
Furthermore, it’s good to have a purifier in the living room with variable settings that you can adjust when no one’s around.
5. Service & Warranty
After 12-18 months, every air purifier needs to be changed. To ensure a quick and easy replacement, make sure your after-sale service is good.
Moreover, your purifier is a big investment. If you want to protect yourself against manufacturing defects, ensure that the product comes with a long warranty.
How to choose an air purifier in India
While choosing an air purifier look for two things:
- An air purifier that removes harmful particles and gases.
- The ability to circulate the majority of the air in the room several times during the hour using fans.
Make sure the air purifier you choose can handle both of these tasks well.
Additionally, all the air in your room should be processed through your air purifier five times every hour. Many manufacturers list the maximum or recommended room size on their air purifiers, and some even mention how many air exchanges an hour the purifier can handle.
You should also look for Clean Air Delivery Rate (CADR) ratings for smoke, dust, and pollen. A CADR rating is better because it is independent of room size.
To find the right air purifier for your space, multiply the width and length of your room, then search for a CADR rating that is about two-thirds of that number.
For instance, According to the EPA’s recommendation, five air changes per hour require a minimum CADR score of 65 for a 100-square-foot room, and a minimum CADR score of 390 for a 600-square-foot room (with 8-foot ceilings).
You can also search for CADR-certified air purifiers by room size, brand, and CADR rating in AHAM’s ( Association of Home Appliance Manufacturers) database of CADR-certified air purifiers, even if your air purifier doesn’t display a CADR rating.
Moreover, AHAM’s vice president for communications and marketing, Jill Notini says it may seem logical to buy the largest air purifier with the highest CADR rating. “But that’s not how it works,” she says.
The volume may become too loud if you overtreat. Hence, choose an air purifier that runs quietly or cycles on and off frequently to circulate the air. As a result, there’s less noise.
Additionally, it may be necessary to consider choosing an air purifier suitable for your specific situation, such as health or pets. To find an air purifier that fits your needs, consider the following.
Air purifier selection based on personal preferences
- A true HEPA filter air purifier is preferred if you are dealing with Asthma. However, avoid purifiers based on Ozone. (True HEPA technology ensures 100% elimination of allergens)
- In case of low immunity levels and when on dialysis, air purifiers with True HEPA filters and prefilters should be installed.
- If you are living near a construction area choose an air purifier having strong pre-filter. Also, replace the pre-filter frequently.
- Get an activated carbon filter if you live in an industrial area. By using these, you can remove odors from the air.
- If you have a pet at home, you should choose a strong air purifier with a pre-filter. Using these will prevent you from breathing pet hair.
However, prior to buying an air purifier, you need to consider some additional factors.
A few things to consider before buying an air purifier
1. Cost of replacement filters
Generally, you should replace pleated filters every 6 to 12 months, and activated carbon filters every three months.
You can tell when the filter needs to be changed (or cleaned) by an indicator light.
2. Energy Star Logo
A few labels may be visible on the packaging. First, there is the Energy Star logo. Buying an air purifier that works around the clock is essential, and you should also keep in mind the cost of electricity when shopping. The Energy Star certification makes purifiers 40 percent more energy-efficient than standard models.
Additionally, you may see a Verified seal from the Association of Home Appliance Manufacturers. On many air purifiers, AHAM’s voluntary certification program provides clean air delivery rates (CADRs) and room size guidelines.
3. AHAM seal
The AHAM Verified seal means that an air purifier can handle the room size specified on the seal. However, do not be fooled by manufacturers’ claims. Several air purifiers that were tested did not fit the claimed rooms.
4. Consider sizing up as well
Most large room models (350 square feet and larger) work well in smaller rooms as well. The lower the speed, the quieter it is-which is ideal when watching TV or sleeping.
5. Noise
Think about how well you can live with an air purifier, not just how well it performs. Since these machines are always on, they should be quiet. You can find a model’s decibel levels on its packaging or website listing. (A noise level of 50 decibels is roughly comparable to the hum of a refrigerator).
Finally, there are two more features you should look for in an air purifier and you will be able to decide which is best for you.
Additional features to look for in air purifiers
1. Air pre-filter
In some air purifiers, especially those for pet owners, there’s a pre-filter for catching pet hair before it goes through the HEPAs and activated carbons. This protects the unit’s more expensive filter from becoming clogged and extends its life. It is usually possible to vacuum or wipe down these filters and reuse them.
2. Air quality monitor
An air quality monitor is typically built into air purifiers designed for medium to large spaces, which provides visual feedback and automatically adjusts the fan speed to maintain optimal air quality.
It also saves energy by running the fan only when necessary. You can also control some air purifiers via an app, see air quality data and receive alerts when filters need to be changed.
Following your decision to purchase an air purifier, the next step is understanding how to optimize its performance.
Tips for making your air purifier work at its best
You can make the best use of your air purifier by keeping the following points in mind.
- Keep filters clean or replace them regularly: If the air purifier’s filter is dirty, it will not be able to function efficiently. Hence, you should replace pleated filters (or clean them if they are vacuumable) every six to 12 months, and activated carbon filters every three months.
- Choosing the right spot is important: In case you only have one unit, place it in your most frequently used room. Typically, that’s the bedroom. When you plan to use an air purifier in multiple rooms, you may want to purchase one for each. At that time, make sure you place it in an area where nothing can obstruct airflow, such as away from curtains.
- Change the speed as needed: When you are not in the room, run it on high speed, and when you are nearby, turn it down to low. This will avoid noise disruptions. You can also buy an air purifier that’s certified for a larger area so you can use it at low speed.

Air purifier buyer’s checklist
Let’s make your air purifier buying experience easier. Take a look at this air purifier buyer’s checklist and find the perfect one.
- Firstly, in order to find out how much space you have, measure your room’s size.
- At a minimum, you will need a HEPA filter for your air purifier.
- Calculate the CADR minimum rating based on the size of your room. There are different rankings for smoke, dust, and pollen. Smoke (the smallest particles) is rated lower than dust (medium-sized particles) and pollen is rated higher than dust (larger particles).
- Find out what kind of filters you need. You will get the best results if your purifier uses a pre-filter, a HEPA filter, and an activated carbon filter, but you can potentially save money on either if you do not need them. In addition to pre-filters, activated carbon filters are essential for gases, VOCs, odors, and larger pollutants like pet hair. Spend a little more on activated carbon if you are renovating or living in an area where wildfire smoke is a problem.
- Ensure that the filter is of the right type. Stick to HEPA filters that filter out at least 99.97% of particles larger than 0.3 microns.
- To ensure an air purifier is energy efficient, look for the Energy Star logo.
- For each fan speed, check the decibel rating. The lowest speed of an air purifier should operate below 30 decibels so that you can sleep while it runs. At the highest speed, check the noise level as well. In order to measure the CADR rating, it is necessary to determine the speed at which the air will be cleaned most efficiently. It is particularly important to have a high fan speed sound level if your air quality is expected to be poor for a long period of time, such as during wildfires. A noise level of over 50 decibels hinders conversation.
- To keep the air of a room circulating, look for a mode that turns on the air purifier periodically. It could be on a schedule or based on a built-in air quality sensor.
