Buying Guide for Best Air Purifier in India
India has six out of the top ten polluted cities in the world. The first is New Delhi. 1.25 million people die annually due to air pollution, according to the World Report of Air Quality.
The air that we breathe inside our homes is worse in comparison to the air outdoors. This is because the US Environmental Protection Agency certifies that air indoors is polluted five times more than outdoor air.
Therefore, it applies to the Indian conditions, with most of its cities making it to the most polluted list. To solve this problem, you must choose among the best air purifiers in India. Our buying guide will help you understand their features.
Before diving into the guide, we will first discuss its basic aspects.
An air purifier helps to purify the air that you breathe and protects you from several respiratory diseases. It has different filters for trapping pollutants and dust particles that are microscopic and harmful.
The Origin of Dust
Dust is present everywhere in our breathing air. That is why patients with respiratory diseases have difficulty breathing such polluted air.
Types of Air Pollutants
The following are the most common types of air pollutants.
- Dust mites and dust.
- Residues from carbon after the burning of camphor and incense smoke.
- Chemical cleaner, aerosol spray toxins, odors from cooking.
- Pollen, fungi, and plant spores.
- Virus and bacteria.
- Hair and pet dander.
- Spores of mold.
- Smoke from tobacco.
Need for a Home Air Purifier
We may need an air purifier in our home for the following reasons.
If you find yourself coughing and sneezing often, there is a good chance that you suffer from a dust allergy. Air purifiers at home remove allergens such as pet dander and pollen.
Asthma patients tend to have difficulty breathing when there is polluted air. Therefore, an air purifier at home is a must. Also, it ensures that the patient does not suffer from further respiratory problems.
Sensitivity from Chemicals
Aerosol Sprays help you to repel cockroaches, mosquitoes, and flies. These can release toxins in the air that you breathe. Even sprays used for medical purposes cause air pollution. That is why you need an air purifier.
If you have a smoker in your home, it is sure that your home has some degree of air pollution.
The smoke that comes from the kitchen, incense sticks, and burnt camphor degrades the air quality. Therefore, you need to buy an air purifier to eliminate such smoke.
Hair Pollutants and Pet Dander
Having pets means exposure to its hair and dander that you unconsciously inhale. So, an air purifier may help you in such cases.
Types of Air Purifiers
You can choose among the best air purifiers in India based on the kind of filtration method.
There are four different technologies of air filtration that we can avail of in India.
HEPA Filter (High-Efficiency Particulate Air)
HEPA technology of filtration is the best among filters. It has a filter of dense paper that traps contaminants that are airborne. It can remove different air pollutants like fungi, pollen, dust, mold spores, smoke, and pet dander.
You have to be careful while buying air purifiers with HEPA filters. Also, you should not go for terms like ‘HEPA Type’ or ‘HEPA like.’ Only True HEPA Filters are genuine.
These filters eliminate the air pollutants completing without releasing them back into the air. Therefore, they are well-suited for respiration problems.
They can target finer particles less than 0.3 microns. But, they are expensive and do not remove odor.
Ionic filtration is a unique technology of filtration that emits charged ions in the air and gets attached to airborne contaminants. Then they fall on the floor after becoming heavy.
These air purifiers with ionic filtration come with an equipped electrostatic plate collection for attracting these particles. This technology of air purification removes particles around 0.1 size microns.
They effectively remove air contaminants such as dust, pollen, VOCs, mold spores, smoke, fungi, bacteria, and virus.
The ionic filtration is cheaper than the HEPA filters. They do not need a lot of filter replacements and maintenance. As it does not have fans, it makes minimal noise.
They need frequent cleaning with water and soap. Another disadvantage is that ozone traces can lead to respiratory problems in patients.
UV light technology emits an ultraviolet light that is not visible to the naked eye to attack the air pollutants. There is an absence of the physical filter by which the polluted air passes during filtration.
It is not released in the room, so it’s safe for humans. It primarily eliminates viruses and bacteria and makes the air free from disease-causing particles.
Besides, they do not need replacement frequently and create a sterile environment in the room. Moreover, it is not suitable as a stand-alone technology.
Activated carbon works as an excellent filter. It is also used in refrigerators and water purifiers for removing bad odors. Their pores are absorbent and trap chemical gases, odors, and fumes.
They do not eliminate particles that cause different health problems but remove bad smells. Furthermore, it deals with gas and chemical fumes, bad odors from smoke, cooking, paints, and pets.
Also, they are cheap and easily replaceable and make the room fresh at all times.
It only reduces fumes, odors, and smell and cannot deal with other types of contaminants.
Size of the Room
You have to calculate the room size where you have to install the air purifier. It is because each air purifier comes with its own room coverage.
Replacement of Filter
You need to change the filter of your air purifier periodically. But its frequency depends on the quality of air in your town and city. For instance, you need to change them weekly in cities like Delhi as there is severe air pollution. Typically, filters last from one to six months.
Level of Noise
You should consider this aspect if you want to use the air purifier at night. If so, you must make sure it does not hamper your sleep.
Noise generally comes from the fans installed inside.
CADR refers to the Clean Air Delivery Rate, which indicates the time required to purify the room air. You have to calculate it in a cube per minute.
350-450 is the standard CADR rating.
Air Change Per Hour (or ACH)
It is a mechanical rating that refers to the amount of volumetric air the purifier can take in an hour. In other words, it indicates the number of times the air of an individual room can be purified.
3 ACH means you can purify the room thrice in an hour.
Sensor of Air Quality
It detects the room’s air quality. So, this helps you determine if your devices should be at auto shutdown, mode of power-saving, or auto shutdown.
FAQs to Buy Air Purifier
How frequently should you replace a filter in an air purifier?
It mainly depends on the outdoor and indoor air quality. Usually, filters need to be replaced annually. But, the quality of air is poor in cities such as Kolkata or Delhi. Therefore, you need to change filters more frequently.

Which is the best air purifier with regards to performance?
You must always choose an air purifier with three stages of purification. It must consist of HEPA filters, pre-filter, and carbon activated filter. Air purifiers in modern times also have methods of UV filtration.
How to lower the noise made by air purifiers?
The noise from air purifiers comes out of fan speeds. Reducing the noise can be done by lowering fan speeds. Nowadays, the air purifiers have in-built sensors that indicate the fans’ impurity level and speed accordingly. So, they help to reduce the speed at night by providing the comfort of a high degree.
What are the drawbacks of air purifiers?
The drawbacks of air purifiers include a change at frequent intervals. Entering with a manufacturer into the AMC is better. But alternatively, you can buy air purifiers with a filter changing alarm. Hence, it notifies you if there is a need for a filter replacement.
