Buying Guide – Best Air Purifiers

Air purifiers are comparatively yet to be introduced in India, and the technologies of air purifiers are also getting enhanced with time. So, to make you understand all the things, we have prepared this buying guide for you. It will make your choices clearer and will help you land on the best air purifier in India.

What is an Air Purifier?

First of all, we should know what an air purifier actually is.

Air purifiers are HVAC attachments or small devices which help in improving the quality of air inside our homes by removing impurities from the air. Air purifiers are a proven good thing for those who have any kind of respiratory problems or also to maintain good health.

Why do we need an Air Purifier for our homes?

A good air purifier will give you several benefits. The airflow inside our home is just very limited because of the walls all around. As a result of this, many kinds of air pollutants get accumulated inside the rooms. And an air purifier can increase the flow of air in our homes and thus help in improving the quality of air.

The process of purification is really vast. Even the bad odors which get stuck in the rooms while doing some specific activities can be taken away with air purifiers. Also, the air cleaners work well for patients suffering from respiratory issues.

Type of Pollutants Stays Inside House

Here we are giving a list of some pollutants which can be eradicated out of the indoor air with room air purifiers.

Airborne Particles

The airborne particles such as pollen, dust, and lint, which are harmful to inhale with air, can be eliminated by an air purifier. When these pollutants do not float in the air, that will make the air healthy and easy to breathe.

Sources of Indoor air Pollution

Tobacco Smoke

Many people smoke in their homes, and if you live with one of those people, then you may get irritated with such a smell. The tobacco contaminated air, along with being irritating, is also very harmful to the health. You may also get some related diseases if you inhale such a smell regularly.

When someone else is smoking, and you are also inhaling that smoke, it is called secondhand smoke. It is also generally harmful to the health. With an air purifier or clean air machine, you can dispose of this smell, and thus, it will prevent the side effects of secondhand smoke.

Household Gases

It is wondering, but about 90% of the poison found in the air comes from our homes themselves. The cleansers which we use at our homes remove out some toxic gases which account for air pollution. Some solvents like pesticides, paint, aerosols, pesticides, bleach, and more which we may have at our home, produce gases. These gases cause irritation.

However, they are not as harmful as other pollutants, and tobacco smokes. But when we get exposed to such gases for a prolonged time, it causes the risk of some harmful health issues. These may be related to the lungs, some parts of the nervous system, or kidneys.

Another toxic gas found in every household is Carbon Monoxide. This gas affects the circulation of oxygen in the whole body. This gas is evolved from heaters, gas stoves, and generators. Being in the exposure to this gas for a long time may cause dizziness, headache, or fatigue. A home air purifier will help you in fighting such issues.

Excess Moisture

We add moisture to the environment with our daily activities like cooking, washing dishes, bathing, and drying clothes. Heaters may also aid in enhancing moisture contents in the air. It also happens in winters when everything becomes moist.

Such moisture enhancements can cause the growth of molds and the peeling of paint on the walls. Many air purifiers have dehumidifiers in them, which prevent such conditions by decreasing the amount of moisture in the air. It will definitely make you more comfortable and also healthy.

Volatile Organic Compounds (VOCs)

These also include some gases which are found in households. Some building materials such as plywood, glues, and particleboard evolve out a VOC named formaldehyde. It is a harmful VOC gas that does not have any color, but its smell is very bitter and acrid.

Burning of fuels, tobacco burning can also evolve out VOCs, which may cause nausea or dizziness in people. Regular exposure to such gases can also aid in some sort of damages to the kidney, nervous system, or liver. These may also corrode the metal appliances at your home. Air purifiers with HEPA filters are good for eliminating such gases out of the home.

Particles found in the air

There are several tiny particles that can be found in polluted air. Such particles may measure just two or three microns in width or may also be less than this. The differently sized particles of this type may be hazardous to our health. As we have mentioned in some PM 2.5 and PM 10 label reviews, they are related to such particles only.

PM 2.5 and PM 10 size comparison

  • PM2.5 – They are the smallest particles present in the air that are harmful to our health as well. The size of such particles is as small as 2.5 micrometers. Being tiny in size, they can easily enter our bloodstream or in the lungs too. Despite being microscopic, they can cause serious medical conditions.
  • PM10 – However, these are slightly larger than the PM2.5 particles. Still, these are very harmful to our health, just like the earlier ones. They are sized around 10 micrometers. The best air purifiers can cop up with such small particles found in the air also. And thus help in enhancing our health and decrease the chance of any such health issue.

Working of an Air Purifier

You must be wondering how an air purifier can clear out even the tiniest particles from the air. So, to clear this doubt, we will be trying to understand how it works.

The purification is done by two components associated with an air purifier. These are fans, and another one is a filter. The function of the fan is to pull the air inside the purifier and evolves it out after purifying. When we switch on the purifier, it pulls the polluted air inside the appliance and then filters purify the air which came inside. After this, the clean air is thrown back outside after the purification is done.

Air Purifier Working Process

So, the main component which functions to purify the air is the Filter. These filters are made of either mesh, fiber, or paper. Some models have just one filter in them, while others may have more than one. The filters need to be replaced or cleaned after a certain time. So, ensure how much effort you will have to give in for its maintenance and proper functionality.

Advantages of Air Purifiers

There are a number of benefits which you can avail yourself of with the best air purifiers. Knowing the benefits, you will realize how important an air purifier is for your home. Here are some advantages of using air purifiers:

  • They clean the air inside our house and make it healthy to breathe in.
  • They can eliminate the irritating smells while we cook something.
  • They can eliminate any allergen from the air.
  • They help in making the smoke go away, be it tobacco smoke or cooking smoke.
  • They help in removing harmful pollens or bacteria from the air and thus prevent any diseases from them.
  • People having air purifiers at their homes stay away from seasonal allergies.
  • Some advanced air purifiers can remove as much as 99% of germs and viruses from the surrounding air.
  • Air purifiers keep your lungs away from any airborne diseases.
  • You can place them anywhere in your house.

What to consider before buying an Air Purifier?

Now that we have discussed some important aspects of an air purifier, now it is time to make a decision on which one to buy. Here we will be looking at some important points which we all need to consider before purchasing an air purifier. These points are:

Size of your room

The amount of air present in the room is determined by its size. So, the larger the room is, the bigger purifier you will need and vice versa. Before buying a purifier, check the area of coverage in the section of the product description to identify whether it will suit your room or not.

CADR Rating

It tells us how much clean air is delivered by the purifier in an hour. It will tell you an estimation of how well the purifier works in terms of its air cleaning ability. This is indeed an important aspect of landing on the best purifier for you. However, not every purifier has a CADR rating. But look for the same for purifier which has this rating.
Here is a list indicating what you can expect from a certain CADR rating:

  • Under 60 – Bad
  • 60 to 120 – Okay
  • 120 to 180 – Good
  • 180 to 250 – Very Good
  • More than 250 – Excellent


Usually, air purifiers do not take a lot of space. But, if you are going to use air purifiers in different rooms, then you can go for lighter ones. Some models are mobile because they have caster wheels with them. Their size is generally enough to get fit in any space of your house.

Just make sure that it has an empty space of about 18 inches around for better airflow.


The air purifiers make a bit of noise. Every model has a different intensity of emitted noise. So, if you want to keep the purifier near you while sleeping or doing anything, then check for this factor also. Buy one with low noise emission.

Power Consumption

For the whole time you keep them switched on, they will consume electricity. So, check for the energy consumption of the purifier before buying one for you. You can know this by the device’s star rating and check the description for proper information.

Cost of Maintenance

For a long time working on the purifier, you will also need to maintain it well. Before you land on your favorite air purifier, check whether the maintenance cost will suit your budget or not. It is essential for a long-running efficiency.

Most air purifiers have carbon or HEPA filters which need to be replaced often. As these captures even the smallest particles from the air, they may get clogged too. In contrast, Ozone or Ionic generators do not need much maintenance or frequent replacements. But they are also not as efficient as others.


It is always a good idea to purchase anything from trustworthy brands only. Many brands claim that their products are the best among all the brands, but still, you should not fall for such words. So, rely on the recognized brands which may provide you with the best quality purifiers and incredible after-sale services.

Frequently Asked Questions (FAQs)

How often should you replace the filter of an air purifier?

It is always better to replace filters at the end of each year. However, in some areas where the air quality is poorer such as in industrialized areas, you may need to replace the purifier filter more often. So, consider air indoor and outdoor quality and then determine how often you should replace the filters.

What type of Air purifier is best for homes?

To have an efficient air purifier that may provide you with excellent performance, you should always choose a purifier with a multi-stage process of purification. The best purifiers are those with a 3 level of purification technology. So, consider at least a purifier with a pre-filter, activated carbon filter, and HEPA filter. It will be an ideal choice for your home. However, if your budget allows, you can also go for an air purifier that uses UV filtration technology also.

Does an air purifier cool the air in the room?

No, any air purifier does not cool the indoor air. Instead, it just aids in the purification of the air.

Is it okay to keep the air purifier on for a long time?

Yes, it is okay if you keep the air purifier running for the whole day or the whole night. However, keeping it running continuously will lessen the efficiency also. So, you will have to maintain the purifier by cleaning it more frequently in this case.

How an Air purifier compliments an AC?

An air purifier recirculates the indoor air only inside the room and does not bring in the outside air. So, it will not bring any fresh air, and the existing impurities will remain accumulated in the room only. So, if you have an air purifier, it will make the air coming from the AC cleaner and away from impurities. This combination will work even better if your AC has any additional filters with it.

Are dirty purifier filters harmful to our health?

Sometimes, the bacteria trapped on the filter start to feed on the other trapped particles. Also, it is possible that the trapped bacteria get thrown into the room air if you do not clean the filter frequently. The spores may also get back into the room. In case of such things happening inside your purifier, it may make you fall sick. So, it becomes important for you to clean the filter frequently.

If we use an air purifier, will it have a negative impact on our health?

No, air purifiers do not have any negative impact on our health. Instead, they improve our health by enhancing the quality of air around us. It eliminates the contaminants which are harmful to the air and makes the air even more suitable for our breathing.
However, try to stay away from the air purifiers which evolve or use ozone gas because they may cause respiratory issues such as asthma.

How can we differentiate between an Air purifier and a Humidifier?

Both are very different in their functioning. The function of an air purifier is to trap the pollutants or impurities from the air and thus, in turn, provide you with clean and fresh air. In contrast, the function of a humidifier is to kill the mold which is present in the moisture. Thus, it helps in reducing the humidity in the air.

Can you decrease the noise of an air purifier?

The main source of noise in an air purifier is its fan. So, when you reduce the speed of the fan, it will minimize the noise too. However, some models of air purifiers also have sleep mode or night mode in which the noise automatically gets decreased. Also, it does not have any effect on the efficiency of the air purifier.

Bottom Line

This article discussed everything important that you need to know about the best air purifiers in India. You are free to choose any of the purifiers from our reviewed ones, or you can go and choose some other one.
