How to Choose the Best Air Purifier for Home
As the number of industries, factories and vehicles in our cities keep increasing, the pollution in our air also keeps increasing exponentially. After a long day at work when you come back home after dealing with all these pollutants, you would expect that the air in your house should be better. But, guess what? It is not. In fact, experts believe that the air inside your house could be a lot more polluted than the air outside.
Indoor pollutants are often generated by building materials, air fresheners, and perfumes, cleaning products, furniture, carpets and upholstery. And these pollutants keep building up as time goes by. This is because, in contained spaces, air cannot circulate freely and does not have a chance to clean itself up. When you breathe the air containing these pollutants, it can lead to a variety of infections and respiratory problems.
This is the reason why the need for the best air purifiers for home are becoming increasingly popular by the day. They are no longer a luxury but an absolute necessity.
How do air purifiers work?
Air purifiers for home have a simple mechanism of working. They use motorized fans to draw the polluted air into the device. Inside the device, this air passes through a series of filters several times to get rid of all the particle and chemical pollutants in it. Some best air purifiers in India also have the mechanism to get rid of the microorganisms like viruses and bacteria that might be present in the air. The purified air is then released through air vents into the room.
Advantages of Using Air Purifiers
If you are still not sure about whether or not you want an air purifier for your house, then here are a few benefits of using air purifiers.
1) They ensure that you and your family are breathing fresh and good quality air. This avoids infections and other respiratory conditions.
2) No matter how much you clean your house. There will always be dust floating around your house. But, air purifiers trap almost all the dust in your home, giving you a clean and fresh feeling.
3) They remove odours. Whether it is odours from cooking, odours from perfumes or just any unwanted odours floating around in your house, your air purifier can get rid of all of them for you.
4) They can neutralize smoke. If you smoke or have a family member who smokes, then the smell and smoke from cigarettes can be harmful to all the other members in your family. Using an air purifier neutralizes the smoke in the air, making it cleaner for others.
5) Having a pet is great. But sometimes, pets can release a lot of allergens and odours into the air that are not good for you. Air purifiers trap these allergens. So now you can spend more time with your furry friend without worrying about allergies.
6) They can trap up to 99% of all airborne bacteria. This is why, if you have a weak immunity system, air purifiers are highly recommended for you.
Best Air Purifier in India 2024 – Things To Know
As the pollution in our cities keeps increasing, the demand for the best air purifiers for home use is also increasing by the day. To keep up with this demand, companies come up with a variety of air purifiers that can match your needs and demands. If you are on the hunt for a good air purifier then, it can get really overwhelming to choose between all the different options that are available. This is why we have made this buyer’s guide that covers all the things you need to know before buying the best air purifier in India so that you can make an informed decision.
1) Air Purifier Technology
Air purifiers use many different kinds of technologies to filter out pollutants and make your air cleaner. Here are a few of the most popular ones.
a) HEPA Technology: HEPA stands for High-Efficiency Particulate Air. This technology has been in use for many years now and can be seen in common household appliances like air purifiers and vacuum cleaners. The HEPA filter is an extremely fine, almost fibre like material that has been folded back and forth several times and it resembles the shape of an accordion. It is capable of filtering out 99.97% of all particles that are larger than 0.3 microns.
For comparison, the human eye can only see the particles that are greater than 10 microns. So, this filter traps chemicals, germs, moulds, pollutants and other substances that are not visible to the human eye. From a sanitation perspective, it is one of the best technologies out there as it can reduce the chances of infections in your family.
HEPA technology uses a powerful fan to draw polluted air into the purifier. In the purifier, this polluted air comes in contact with the accordion-shaped filter. This filter creates a maze of fibres that has ample amount of space for the air to be pushed through. As the air passes through this maze, all the particles, pollutants and other unwanted substances get trapped into the filter. For bacteria, virus and other small particles to get trapped the air needs to pass through the maze 2 or 3 times.
At the end of the third or fourth cycle, you will have clean and breathable air. One thing to keep in mind is that the dust that gets trapped in the filter stays on it. So, you will need to replace the filter every 1 or 2 years depending on your needs. But the best part about HEPA technology is that it does not create any harmful by-products and is extremely safe to use.
If you have family members who suffer from asthma, allergy or any other respiratory conditions then you should definitely go for the best air purifier for home in India that uses this technology.
- Can trap all the particle pollutants present in air
- Useful for people with respiratory conditions
- Does not create by-products
- Expensive in the long-term as filters need to change frequently
- Cannot trap harmful gases or odours
b) Activated carbon technology: One major drawback of HEPA technology is that it is made only for particulate matter and cannot trap chemicals, gases or odours. This is why we have activated carbon technology. Activated carbon is a chemical form of carbon that has been heavily processed to make it porous. This porous structure allows for air filtration. The popularity of activated carbon is increasing by the day and it is used in common products like face washes because of its excellent ability to absorb impurities and chemicals.
The activated carbon filters are made up of a number of molecular sized pores that have strong chemical bonds. These pores allow it to work almost like a sponge absorbing all the toxic gases, chemical pollutants, odours, tobacco and smoke. These trapped products are not back into the air but are completely absorbed by the activated carbon. This reduces the possibility of recontamination.
When activated carbon purifiers are used in households, they do an excellent job of absorbing multiple chemicals like formaldehyde which is found in carpets, upholstery and wood panels. Perfume odours and harmful chemicals from all the other household substances can also be eliminated easily. While activated carbon purifiers can do an excellent job in eliminating gases and chemicals, they cannot trap particle pollutants.
So, depending on your family’s needs, requirements and exposure to chemical substances, you should decide which kind of air purifier for home works well for you. If you need both of these functions, then you can go for high calibre air purifiers that can eliminate particles as well as chemical pollutants.
- Absorbs harmful chemicals, gases and odours with ease
- Does not cause recontamination
- Does not produce harmful by-products
- Cannot capture particle pollutants
c) UV Technology: UV technology is not a technology that can be used on its own. However, when combined with other particle filters, it can work wonders. UV Rays are popularly known for being able to kill living cells and this is why they do an excellent job in killing microorganisms. Air purifiers that use UV technology usually have an UV lamp installed as a post filter. The polluted air after passing through the particle filter goes through this UV lamp and all the bacteria, viruses and other microorganisms present in the air get killed very effectively.
Apart from this, UV filters are also extremely useful for converting oxygen and water molecules found into air into ozone and hydroxyl. Hydroxyl is popular for reacting harmful chemicals and transforming them into harmless substances. The ozone created in this process is not useful and it is a harmful pollutant.
However, high-end UV filters have the technology to minimize or totally eliminate the ozone content. Can this type of purifier kill 100% of germs then? Well, that depends on a lot of factors. The effectiveness of the UV filter depends on the amount of time the air is allowed to be exposed to the UV rays and the wattage. The longer the air is exposed to UV rays, the more germs get killed.
Even though this is a very effective method of killing microorganisms and making the air healthier, the UV technology is not good enough to be used on its own. It has no effect on particle and chemical pollutants. It is better used alongside other filters.
- Very effective in killing microorganisms and controlling diseases
- Has a wide range of applications in hospitals, houses and public places
- Produces harmful by-products like ozone
- Cannot be used on its own
- Is not effective on particle pollutants.
d) Ionic technology: A natural particle with either positive or negative charge is known as an ion. Ionic purifiers use chemical injections and react with pollutants in the air to get rid of them. They were hugely popular in the early 2000’s but as HEPA filters gained popularity, ionic filters were brushed under the carpet. But, they can be very effective if used well.
The ionic purifiers are of two types 1) Ionizers and 2) Electrostatic precipitators.
The difference between these two types is huge.
Ionizers use a large number of negative ions. Negative ions are just oxygen atoms that have gained an electron. This extra electron is not stable and tends to react with particles such as pollen, dust, chemicals and other toxic substances to form new compounds. This process keeps repeating until the newly formed substance becomes so heavy that it cannot stay in the air.
The particle then settles down on nearby objects like window panes from where they can be wiped off very easily. The problem with ionizers is that they are not really getting rid of pollutants. Rather, they are just finding a way to take away these pollutants from air and get them to settle down on other places where they might not be as harmful.
Electrostatic precipitators, however, seem to overcome this problem. They work similarly by producing negative ions that react with toxic substances. The difference is that the newly formed substance settles down on inbuilt plates that are positively charged. This way, you can avoid the hassle of having to clean windows and doors frequently. This is why the electrostatic precipitators are much more popular than ionizers.
But in the process of breaking down toxic substances, both the ionizers and the precipitators produce unnecessary by-products like ozone.
- Ionic purifiers can get rid of both particle and chemical pollutants
- They are filter less and can save money on constant filter replacements
- They are much quieter
- Less effective than HEPA filters
- Produces harmful by-products
- Does not really eliminate or absorb pollutants only masks them
e) Ozone generators: As the name suggests, these purifiers intentionally produce ozone to get rid of toxic substances and microbes. They are definitely not suited for household use but they can be very useful for commercial purposes. These ozone generators usually use UV rays to breakdown the nearby oxygen molecules and convert them into ozone. This ozone is a highly reactive substance and it can react with the nearby pollutants and convert them into other harmless substances.
In large factories and industries, ozone generators are used to disinfect the air and kill harmful microorganisms. However, it has no effect against particle pollutants or biological contaminants. The problem with this method is that ozone itself is a very harmful substance. Though it can get rid of germs and other pollutants, it is not safe for humans to inhale ozone. It can damage your lungs and cause other respiratory issues. Therefore, ozone generators are strictly not recommended for household use.
- Can effectively kill microorganisms and get rid of chemicals
- Harmful to health
- Does not work against particle pollutants
Among all the 5 different types of technologies used in air purifiers, we believe that HEPA and Activated Carbon Technologies are highly recommended for household usage. They can filter your surrounding air effectively and make it cleaner.
2) Size of your room
Probably one of the most important factors that you have to consider before buying the best air purifier for home is the size of the room in which you intend to place your air purifier. Air purifiers come in different sizes, power efficiencies and delivery rates. There is no one size fits all mantra here. You have to choose a purifier based on the size of your room.
The coverage area of the purifier that you choose should be able to match the size of your room. If the coverage does not match the size of the room then the air in that room will not be able to be purified efficiently. It is always better to get a larger sized unit as they can clean up all the air in your room and are more noise efficient as well.
3) Air Purifier Placement
The placement of your air purifier is also an extremely important factor. Large living rooms and rooms with high ceilings are usually very difficult to purify. But, if you want optimum air purification even in such large rooms, then you should look out for the best air purifier for home that always attempts to direct purified air towards the side of the inhabitants.
Also, when you place the air purifier inside the room, the space around it should be at least 18 inches. So when choosing a purifier for a particular room it is very important to keep these dimensions in mind. If your room is small and you cannot leave 18 inches of space for air purifiers, then you should go for a smaller one. In your bedroom, the distance between the headboard of the bed and the purifier should be 6-10 feet.
As mentioned before, air purifiers come with a variety of filter options to choose from. You also have the option to choose filter less options though they might not be that effective. It is always better to choose the best air purifier in India that has multiple filters as they can provide more efficient filtration and cleaner air. But how do you know which filters are best suited for you? Well, here’s a quick guide.
- Choose HEPA filters if you have allergies, asthma or other respiratory problems or if you have family members that have these conditions.
- If you live in an industrial area or near a construction site, choose a purifier that has HEPA, pre filter, and activated carbon filter.

4) Clean Air Delivery Rate (CADR)
Clean Air Delivery Rate or CADR is the measure of the volume of air that an air purifier can filter. It is usually measured in cubic feet per minute. This measure covers both the air flow capacity and the particle removal efficiency. It is very important to look out for this measure because the higher the CADR the more air can be filtered and purified.
Manufacturers state that, if the height of the room is 8 feet then, the CADR should be greater than its area divided by 1.55. So if the area of your room is 450 sq. then the CADR for it should be greater than 258 cubic feet per minute. In India, you might not find the CADR that you are exactly looking for. But anything in and around 200 should be able to do a good job for your room.
5) Air change per hour (ACH)
The Air Change per Hour or the ACH rating is another important factor that you should look out for while buying purifiers. In simple terms, it is the number of times that the air in the room is filtered by the purifier. So for instance, if the ACH rating is 3, then the air in the room is filtered about 3 times an hour. This is a measure that determines how efficiently your purifier is able to work.
For people with respiratory ailments, allergies or asthma, experts recommend using a purifier that has a minimum ACH rating of 4. Most manufacturers usually don’t mention the ACH rating of the purifier but it is important to ask for it before you buy.
6) Noise efficiency
Some air purifiers can be extremely noisy while operating. This can be very irritating as air purifiers are mostly used in bedrooms where you usually want it to be silent. It can also be extremely annoying for your neighbours, pets and elderly people in your home. Therefore it is very important to check the noise efficiency of your air purifier before purchasing it.
The amount of noise your air purifier makes depends heavily on its design and motor quality. Filter less air purifiers are much less noisier when compared to filtered air purifiers but they are not quite effective. Therefore, it is advisable to go for a good quality device that is large in size and run it at slow speed to reduce the noise. Air purifiers from some companies are simply less noisy than others. It is always better to check the noise efficiency in the store itself before purchase.
7) Brand value:
When buying an appliance as valuable as an air purifier, it is very important to choose the air purifier in India from a trustworthy brand. Trustworthy brands provide high quality and superior build, maximum performance, elegant designs, greater stability and higher warranty periods. These appliances are usually more durable and long-lasting when compared to other brands. More often than not, low-quality air purifiers use cheaper filters that do not provide effective filtration and need to be replaced constantly.
Therefore, it is always advisable to choose a trustworthy brand. Some popular brands offering the best air purifiers in India are Dyson, Coway, Philips, Mi, Atlanta, Honeywell, Kent, Blue Star, Sharp Air and American Micronic. It is very important to do thorough market research about a brand before purchasing.
8) Warranty and Customer Service
It is always important to check the warranty of an expensive electric appliance before purchasing it and air purifiers are no exception. A warranty of 2-3 years should be ideal for air purifiers. This ensures that you are buying a quality product. Also, check whether the warranty is only for motor failures or for the body as well. A lot of companies tend to provide warranty only for the motor and this must be double-checked.
Another important factor that needs to be checked is the availability of customer service. If your product gets damaged and needs to be serviced, you need to be able to get it done in a hassle freeway. First of all you need to choose a company or a brand whose service centres are within your city. Then your brand should also be able to provide you contact numbers and email ids through which you can get in touch with them easily whenever required.
Budget is always a very important factor to consider before buying a product. Air purifiers can sometimes get pretty expensive, therefore, it is better to decide on the amount of money you are going to spend on it well in advance. Once you have decided the amount of money you want to spend on your air purifier, you can look at features, sizes and accessories available for that budget.
Deciding on a budget early on also makes it easier for you to shortlist by eliminating all the other options that do not fall in your budget range. However, if you want a branded or a high quality appliance, you must be willing to spend a significant amount of money.

This is a very useful feature to have.
Speed adjustments: This feature helps in adjusting the fan speed based on your room size and pollution levels. Some high end models have the option of automatically detecting the pollution level in the air and adjusting the speed accordingly.

Remote control: Having a remote control makes controlling devices very easy. You can adjust the fan speed, turn on or turn off your device and do multiple things from your couch or bed without having to get up every time. The Dyson purifiers come with a remote control. Some models like LG and Philips can be controlled through a mobile app.
Humidifier: If you live in regions with extremely dry climate, then this is for you. You have the option to buy an air purifier with a built in humidifier. It basically adds moisture to the air in your surroundings to prevent dryness. It is extremely useful as it can promote better sleep and reduces infections. If you have babies then this is all the more useful.

However, they come with limited features, require frequent cleaning and might not provide effective filtration like the full sized ones.
12) Quality certificates:
Any electronic appliance that you choose to buy should have an ISI certificate. An ISI certificate is the mark of safety and quality. However, if you want a really good quality product, then also look for the ISO mark. ISO marks are given not to products but to companies. If the company that you chose is trustworthy, it will have an ISO certificate as well. Check for these quality certifications before buying your appliance.
