Top 12 Air Purifiers for Cleaner Air in India (September 2024)

Key Takeaways:

Air purifiers are a must-have for Indian homes: With air quality consistently ranked among the worst in the world, it’s no surprise that air purifiers are becoming an increasingly popular household appliance in India. After all, clean air is essential for our health and well-being.

HEPA and carbon filters are the key players: When it comes to air purifiers, there are two main types of filters to consider: HEPA and carbon. HEPA filters are designed to trap allergens and dust particles, while carbon filters eliminate odors and harmful chemicals. The best type of filter for you will depend on your specific needs and air quality concerns.

Choosing the right air purifier: Finding the perfect air purifier for your home can feel overwhelming. But don’t worry, I’ve been in the tech blogging game for a decade now, and I’ve seen it all. Here are a few key factors to consider:

• Air quality in your area: If you live in a particularly polluted city, you’ll need an air purifier with a strong HEPA filter.
• The size of your home: Air purifiers are rated for the size of the room they can effectively clean. Make sure to choose one that’s powerful enough for your space.
• Your budget: Air purifiers range in price from relatively affordable to quite expensive. Decide how much you’re willing to spend before you start shopping.

If you’re reading this article then you might have an idea about air purifiers but before we begin I’d like to provide some in-depth information about this topic to help you make the right decision while choosing the best air purifier for your home.

Let’s dive into the details.

With the blessings of technological advancements come its curses too. Day by day we are advancing in science and technology whereas on the other hand side effects of pollution are taking a heavy toll on nature, air, and water.

We think that closing all doors and windows in our home will help prevent the toxic air outside from coming in, but sorry news flash, it’s not 100% effective at all. And also if someone in your family smokes or consumes tobacco, then it’ll make it even worse.

People with asthma and other respiratory ailments will suffer a lot simply because each time they inhale they take a lot of unhealthy air which is nothing sort of poison for them. This will eventually deteriorate their present condition further.

Hence, arises the need to purify the air in our homes especially if somebody in the house suffers from allergies or asthma. Purifying the air has become the need of the hour.

What is an Air Purifier?

An air purifier, as the name suggests, is a device that purifies the air, which we breathe in.

In India, we all are aware of the ever-increasing amount of air pollution around us, for example, the air quality in Delhi is getting worse day by day people have to wear masks all the time, and it has adverse effects on our health.

An air purifier reduces the amount of dirt and germs in the air we breathe in and gives us a better quality of air & life.

Functions/Uses of an Air Purifier

The main function of an air purifier is to eliminate all the harmful and allergy-causing substances from the air by using its air filters.

The harmful substances are present in the air in the form of dust particles, smoke emitted from vehicles or other sources, and pollen from plants, etc.

The air purifier machine takes the indoor air inside it by suction, it then cleans the air by using its different filters & methods, eliminating all the toxic substances, germs, bacteria, odors, etc., and throws out the filtered clean air for us to breathe.

Types of Air Purifiers

There are five types of Air purifiers available in the market.

Different air purifiers use different air purification technologies. The majority uses either charcoal absorbents or mechanical filters.

The other techniques include electrostatic, ionizers, ozone, and ultraviolet air filters.

Adsorbent Purifiers

Absorbent purifiers are low-cost filters made from activated charcoal. Activated charcoal is used for its effectiveness in trapping odors & chemical gases from the air.

Activated charcoal filters can be used with HEPA filters to trap impurities in the air like dust, molds, bacteria, pet hair, etc.

They can also absorb VOCs which HEPA & other filters cannot do much about.

UV Light Purifiers

We know that ultraviolet rays are germicidal, and in the air purifying process they do the same job.

A UV light is fitted inside the purifying device, and the air goes in and passes through a ray of UV light, this helps kill microbes, bacteria, and other molds in the air.

The UV light denatures the DNA, rendering it inactive in case of viruses and killing the airborne bacteria.

The process involved here is called UVGI, i.e. ultraviolet germicidal irradiation. Read more about it here.

Ionizers, Ozone Generators & Electrostatic Filters

These are less widely used air purification methods. Ionizers, Ozone & Electrostatic filters are different methods but work on the same principle.

The particles in the air have a negative charge in them, and these ionizers, ozone generators & electrostatic filters have either negative or positive charges, they charge the particles floating in the air.

Now the charge particles are brought down & are settled on the ground thus removing them from the indoor air.

Electrostatic filters have one advantage over the other two, in the case of ionizers & ozone generators the charged particles are left on the ground/floor that you need to manually clean.

Whereas EFs collect the particles inside the purifier only, this is why electrostatic filters are widely used among these three.

HEPA purifiers

If you’re researching these devices, then you must have chrome across this acronym HEPA, the full form is high-efficiency particulate air.

HEPA purifiers work by applying two different mechanisms at the same time, it has two filters, outer & inner. The outer filter’s function is to trap the bigger dust particles, & the outer filter traps smaller particles in the air.

The filters are generally made of fiberglass material, HEPA filters remove up to 99.7% of the dust particles.

One disadvantage of HEPA filters is that they cannot trap viruses, odors, and chemical substances.

HEPA vs Carbon Filters in Air Purifiers: Breathing Easy with the Right Choice

Clean air is essential for a healthy life, but allergens, pollutants, and odors can take a toll on your breathing. Air purifiers offer a solution, but with HEPA and carbon filters as options, choosing the right one can be confusing. Worry not! This guide will break down HEPA vs carbon filters, helping you pick the perfect fit for your needs.

HEPA Filters: Champions Against Allergens

HEPA stands for High-Efficiency Particulate Air. These filters are the allergy warriors, trapping tiny particles as small as 0.3 microns with 99.97% efficiency. Here’s what HEPA filters tackle:

• Allergens: Dust mites, pollen, pet dander, mold spores – HEPA filters capture them all, providing relief for allergy and asthma sufferers.
• Dust and Smoke: Say goodbye to dust bunnies and lingering cigarette smoke. HEPA filters keep your air free from these irritants.
• Bacteria and Viruses (to an extent): While not their primary function, HEPA filters can trap some airborne bacteria and viruses, contributing to a healthier environment.

Carbon Filters: Odor Elimination Experts

Carbon filters are made from activated carbon, a highly porous material that traps gases and odors through a process called adsorption. Here’s what carbon filters target:

• Odors: From cooking smells to pet dander, smoke, and VOCs (volatile organic compounds), carbon filters effectively neutralize unpleasant odors, leaving your space smelling fresh.
• Chemicals: These filters can help remove harmful chemicals like formaldehyde and benzene, often found in paints, carpets, and cleaning products.

HEPA vs Carbon Filters: Choosing Your Champion

Now that you understand their strengths, let’s see which filter suits you best:

• Choose HEPA if: You suffer from allergies, asthma, or are exposed to dust, smoke, or pet dander.
• Choose Carbon if: You’re concerned about household odors, VOCs, or chemical fumes.

The Dream Team: HEPA and Carbon Together

For comprehensive air purification, many air purifiers combine HEPA and carbon filters. This powerhouse combo tackles both airborne particles and odors, giving you the best of both worlds!

Breathe Easy with the Right Choice

Consider your air quality concerns when choosing your filter. HEPA for allergies, carbon for odors, and a HEPA-carbon combo for the ultimate clean. By understanding HEPA vs carbon filters, you can breathe easy, knowing you’ve picked the perfect solution for a healthier, fresher home.

Buy an air purifier that has HEPA filters, as those filters are certified by medical bodies & other institutions…

How do air purifiers work?

The air purifier works in a very simple way: intake the air inside the room, filter it, and replace the populated indoor air with clean air.

As you know these devices have filters, they first intake the indoor air and then use their HEPA filters to get rid of allergens, dust particles, bacteria, and other pollutants floating in the air.

As these unwanted pollutants get trapped inside the air purifier’s filter, you get clean, fresh breathable air in your room circulated back by the device.

In the case of ozone filters, they don’t remove or trap the particles in the air, they thus neutralize them so that they no longer pose any threat. However, there is a drawback to this process, as it may emit ozone particles.

This process is carried out in three stages in most of the air purifiers:

The working can be classified into passive purification, active purification, and a combination of both active purification + passive purification.

Stage One: Pre Filters

Pre-filters are the first line of defense for any device, in this stage, big particles like PM2, dust, mold, etc. are filtered out by the prefilters. Prefilter puts less strain on the rest of the filters, thus increasing their life span.

Stage Two: Deodorization Filter

As I’ve mentioned earlier nowadays many air purifiers can effectively filter out VOC i.e. volatile organic compounds from the air. And these deodorization filters work to filter out gases and VOC from indoor air.

The activated carbon filter effectively absorbs the gas and compounds like ammonia and formaldehyde floating in the air. 

Stage Three: HEPA Filters

HEPA filters are used to trap the smallest suspended particles in the air that escape the first stages of the filtration process. A HEPA filter is known to trap particles as small as 0.0003 millimeters.

Apart from these crucial steps, some filters also used:

UV light kills or neutralizes living organisms like bacteria, mold, fungi, and germs suspended in the air. But they can’t kill viruses but can make them inactive so it poses a serious threat to health.

The negative ion air purification method involves releasing negative ions to capture pollutants in the air, then they fall on the surface like the floor and as a result, you get fresh air to breathe.

Advantages and disadvantages of using an air purifier

One disadvantage of an air purifier is its price is too high. (its prices are likely to fall, as the demand rises.)

A minor disadvantage is that the collection plates in an electronic air purifier need regular cleaning.

The advantage of electronic air purifiers is easy to install and do not involve complex wiring.

They consume less power and hence have fewer electric charges. Their running noise is also negligible.

Pet dander and hair pollutants: Air purification devices also help in getting rid of pet dander and pet hair pollutants from the indoor air.

Pet dander causes allergy and asthma problems in humans. Thus saving you and your family from severe health issues!

Why should you buy an Air Purifier?

Even the air is polluted so badly in India that we don’t even realize that we breathe in dust and germs.

Unfortunately, you can’t purify the outdoor air but on the other way, you can improve the quality of the indoor air.

I saw many people are still debating, whether is it worth it to buy an air purifier.

I mean, how can investing in a device like an air purifier can be a waste of money?

It can clean your indoor air by eliminating all the suspended particles, microbes, and toxic substances that are detrimental to you & your family’s health.

FYI: Do you know that indoor air quality in India is up to 10 times more polluted than the air outside? Sources NCBI.

So eliminating all the polluted air certainly prevents your family members from diseases that are caused by air pollution, thus indirectly saving you a lot of money.

FYI: Air pollution in India cuts off 5.2 years from your life. Source.

If any of your family members have respiratory diseases like allergies & asthma, top health officials in India and abroad recommend the use of air purifiers to improve the air quality at home, especially in cities like Delhi, Calcutta, Punjab, etc. places where air quality is bad to severe.

• Amount of noise each one makes while running, tried our best to select the lowest noise producers that would not bother users.

How to choose the perfect air purifier for your home? – Quick Buyer Guide:

One must keep in mind certain things before buying an air purifier:-

Filter Type

First, one must decide the type of air purifier one wants to buy. There are two kinds of air purifiers:- HEPA Filter and Carbon Filter.

HEPA filters target particles even finer than 0.3 microns (divide a hair strand into 240 pieces and the width of one such piece is equivalent to 0.3 microns) and HEPA filters do not remove odor whereas Activated Carbon filters remove odor along with its normal functions.

An ideal air purifier is one with a combination of both filters, they are expensive but worth every penny.

Room size

Always can calculate the size of the room where you want it to be installed, because each air purifier has its effective room coverage in which it works ideally.

Filter Replacement

This falls under maintenance you need to change the filters of the purifiers periodically, though the actual frequency depends on the air quality of the city or town you live in. 

For example, in Delhi, you’ll need to change the filters weekly basis as the air pollution is severe there.

But typically, an air filter lasts a minimum of up to six months or more, one must go through the durability claim of the air purifier.

So before buying have a quick look at the price of the filters of the product that you’re going to buy.

Noise level

This is a not so important aspect but you should consider it if you’re planning to use it while sleeping at night. Then you should check the noise level of the device, it should not pamper your sleep.

The noise mainly comes from the fans that are installed inside.

CADR Rating

Another vital thing to check while narrowing down the ideal product. CADR stands for Clean Air Delivery Rate, which indicates how long will it take for the device to purify the total air in the room. It is calculated in cubes per minute.

Therefore, CADR the more the better. Anything between 350-450 is a good CADR rating.

ACH – Air Changes Per Hour

ACH or air changes per hour of an air purifier is a mechanical rating that signifies how much volumetric air it can take in one hour or in simpler terms how many times it can purify the air of a specific room.

Suppose a product has an ACH of 3, that means it’ll purify the air in that room thrice in one hour.

Air Quality Sensors

The dust sensor to air-quality monitor should also be verified along with several fan speeds.

Some advanced & high-end air purifiers have air quality sensors that help in detecting the present air quality in a room.

By accessing the quality of indoor air, the devices can act accordingly like if the quality is severe then it’ll run at maximum efficiency if moderate then it’ll run at power-saving mode and if the Quality is good then it will auto shut down until the air quality degrades.

How to select the right air purifier for your room?

First, you need to measure the size of the room where you want to keep or use this air Purifier. A simple breadth x width of the room will reveal its total size in square feet.

The second step is to go through the specification of the product, manufacturers mention the active cover of the devices then you can check whether it fits the dimensions or not.

Third, check the CADR & ACH ratings of the product, it means how much time it’ll take to filter the air and the second one indicates how many times it can purify the indoor air in one hour.

Who should buy it?

Anyone who is worried about the health of their family members or is sensitive to outdoor polluted air.

Investing in an air purifier is not at all a bad investment instead you’re keeping your family members, especially people with breathing problems, asthma, and allergies.

You may be surprised to know that the quality of indoor air is worse than what’s outside, if you’re worried about the AQI of Indian cities, then wonder about the condition inside your home or office.

Air purification systems help improve indoor air quality by eliminating the suspended particles, aerosols, VOC, molds, and bacteria present in the air.

It uses advanced filters to trap them and throw back clean and fresh air to breathe.

After many tests and research, it is seen that these devices can help improve the air quality inside the home and save people from many airborne diseases and disorders.

Hope I’m able to make you understand the importance of having an air purification device at home in India.
