According to the United States Environmental Protection Agency, the air inside homes can be up to 5 times as polluted as outdoors.
The reason being how buildings are constructed and things we bring indoors that release harmful contaminants.
The best air purifiers in India will help you reduce sickness causing elements by purifying the air in your home.
India during festive times, such as Diwali or the wedding season can get incredibly polluted. Delhi and other metropolitan cities can get even more polluted due to the sheer amount of people which leads to vehicle pollution and desperately high concentration of allergens.
Delhi ranked the worst during Diwali of 2019, with the AQI (Air Quality Index) of well over 400, acceptable AQI being 50-100.
Air purifiers are a newer technology that actively work to improve air quality by filtering harmful microscopic elements that can cause irritation or sickness.
Everything about Air Purifiers in India
- How Air Purifiers work: Air Purifiers use a system of internal fans to pull the air from your home, this air is passed through multiple filters that remove harmful airborne particles like dust, pollen, smoke and bacteria. The purified air is then let back into the room and helps to keep the indoor environment healthy.
- What do Air Purifiers do: Air Purifiers not only cleanse the air indoors but also get rid of bad odors, cooking smells, allergens from pets, second-hand tobacco smoke, even dust before it settles in your home.
- Do Air Purifiers help against germs and sickness: Yes, Air purifiers filter the air indoors and helps to fight disease-causing germs and bacteria. True HEPA (High-Efficiency Particulate Arrestance) air purifiers with UV bulbs capture and neutralize up to 99.97% of airborne germs that might get you sick.
- Air Purifier Ratings: ACH and CADR ratings are the most overlooked by consumers while purchasing an air purifier.
ACH stands for Air Changes Per Hour and explains how many times the device can change the air indoors with clean and fresh air. ACH ratings are 4x,5x,6x or greater. 4x ACH rating means the air will be purified 4 times in an hour. Higher the number the more efficient the device is at cleaning the air inside a room.
CADR, or Clean Air Delivery Rate gives you an objective understanding of how effective the device is in purifying the air with respect to the size of the room. Since CADR is not well regulated around the world, it may or may not be 100% accurate with its apparent explanation. It also only measures efficiency against pollen, dust and smoke.
Air Purifiers India : Buying Guide
Types of Air Purifiers
Air purifiers range from the generic fan type, an Eco-friendly and non-electric version, Ultra Violet purifier, ionic and carbon filtration versions are available as well. With varieties to choose from, it is essential that you find the one that best suits your needs. Read through to choose what purifier works best for you and how to purchase the best air purifiers in India.
1. HEPA (High Efficiency Particulate Absorption) Filtration
HEPA filtration method is the highest standard in air purification. HEPA filters use a dense paper filter to trap contaminants and purify the air.
Purifiers with the label “True HEPA Filter” is certified to trap 99.97% of the airborne contaminants. Inferior products that claim to be “HEPA-Type” or “HEPA-Like” amount to 600% less efficiency to the “True HEPA Filters” kind. Look for the True HEPA label to make an educated purchase.
HEPA filters efficiently remove a variety of sickness causing contaminants and is a big help to people with respiratory issues. HEPA purifiers use a rotating fan to pull in air so it can be loud, they also do not clear out odors and are generally expensive to purchase and maintain due to constant filter replacing.
2. Carbon Filtration
Carbon based purifiers use special activated carbon with numerous absorbent pores, to trap fumes and odors due to the activated carbon’s large surface area. Carbon filtration does not remove particles and contaminants, but helps with cleaning out the odor indoors. Carbon filtration is best used to help with pet and cooking smells, fumes and help with making indoors smell great. They are relatively cheap, easy to replace and some of them are even non-electric.
3. Ionic Filtration
Air purification using ions is done by emitting a cloud of charged ions into the surroundings to latch onto particles and contaminants. This forces these impurities to fall onto the surface. A few of such purifiers use an electrostatic collection plate that attract these fallen particles and removes them from the surroundings.
Ionic filtration method is quite efficient in removing contaminants from the atmosphere, but said contaminants remain on the floor or the surface until collected. A collection plate is necessary to clean up all residue, which makes maintenance a bit of a task as the collection plate needs to be cleaned regularly with soap and water. This method also does not affect odors but is relatively inexpensive and helps with keeping the air clean quite effectively.
4. Ultra Violet Filtration
Ultra Violet (UV) filtration method uses UV-C band of the ultra violet spectrum, completely harmless to humans, that destroys pollutants in the air. The UV light is contained in the purifier and does not leak out. It is efficient in getting rid of bacteria and germs in the air that might cause harm. UV filtration does not come as a stand alone device and comes as an added bonus with other filtration devices like A HEPA with UV filtration enabled.
UV light essentially lasts forever and hardly needs replacement and causes a sterile and germ free environment.
Classic and smart enable are two sub-types of air purifiers. Classic type are the traditional version with no feedback from the device. You have to trust that it is cleaning the air efficiently, while smart enabled purifiers have a dedicated app which gives you tonnes of data on how well the device is working and tracking air quality in real time.
Features to look for in an Air Purifier – Buying Guide

- Antimicrobial Treatment – A coating that prevents the build-up of bacteria and microorganisms on internal filters, it helps with increasing the lifespan of filters and prevents the re-release of said bacteria back into the air.
- Photocatalytic Oxidation (PCO) – A more advanced filtering process, coupled with the UV purification method to destroy harmful organic compounds, bacteria and germs from the air.
- Mobile App – A mobile app lets you fully control the features of the air purifier. They help with monitoring data and gives real-time information about the cleanliness of the air and the pollutants present in the room.
