What is an Air Purifier?

Air purifier, as the name suggests, purifies the air by removing contaminants from the air in a room such as dust, smoke, pet hair and dander, harmful allergens and various other floating impurities. It is becoming a necessary appliance as the Air Quality Index of Indian cities are worsening day-by-day.

In this buying guide, I am going to tell you the reasons to buy an air purifier, working of air purifier, how to choose the best air purifier for your needs and which are the top 10 best air purifiers in India/Delhi.

Why You Need an Air Purifier?

Central Pollution Control Board maintains a National Air Quality Index where real-time air quality of 17 Indian states and Union territories is shown. If you live in Delhi like me, then it becomes necessary to buy air purifier because AQI of all stations in Delhi is more than 400(severe and hazardous level).

Also, this is not only the problem of Delhi. According to a WHO report, 9 out of 10 most-polluted cities by particulate matter concentration in the world are from India with Delhi topping the list.

You may be thinking that since you spend most of your time indoors, you are safe from air pollution. You are wrong.

Indoor air pollution, the degradation of indoor air quality by harmful chemicals and other materials, can be up to 10 times worse than outdoor air pollution. This is because contained areas enable potential pollutants to build up more than open spaces do.

An air purifier is helpful for the following reasons:

1. Air purifier ensures you and your family is breathing clean air.

2. Air purifier traps airborne allergens released by pets.

3. An air purifier helps neutralise smoke.

4. Air purifier traps dust.

5. An air purifier removes up to 99 per cent of airborne bacteria.

6. Air purifier keeps your lungs healthy.

How Does Air Purifier Work?

The air purifier uses a system of internal fans to pull the air in your home through a series of filters that remove harmful airborne particles like dust, pollen and bacteria. The air purifier then circulates the purified air back into the room. This process repeats itself several times an hour, keeping your environment healthy.

The pre-filter of an air purifier removes particles up to PM10 size. The HEPA filter removes PM2.5 particles and much smaller particles as well, typically to around 0.3 microns, nearly seven times smaller than PM2.5. Aside from this, an activated carbon filter is also useful as it can trap gases and remove odours

Buying Guide for Air Purifier

1. Room Size

Room size is an important factor while choosing an air purifier. Buy an air purifier that is designed to operate in a space that is 20-40% larger than your room for optimal performance. It will not need to run the fan as fast, and thus will be quieter and consume less energy in that case.

2. Filtration System

To be effective, air purifiers need a multi-stage air filtration system. A multi-stage air filtration product generally has three types of filters.

A. Pre-Filter

The pre-filter acts as the first line of defence and removes PM10 pollutants such as dust, smoke, hair, pet dander, large pollens etc. The pre-filter also helps in increasing the life of the secondary filter by not letting it die sooner.

B. HEPA Filter

The High-Efficiency Particulate Air Filter traps PM2.5 pollutants which are too fine to be stopped by the Pre-Filter. They can filter particles of up to 0.3 microns in size. HEPA filters are considered as the industry standard for air filtration products. These filters can remove up to 99.97% of pollutants from the air.

C. Carbon Filter

The carbon filter is used for removing volatile organic compounds (VOCs), gaseous substances and odours from the air.

3. CADR(Clean Air Delivery Rate)

It is an important metric for air purifier performance and represents the speed of purified air emitted by the purifier. Go for a purifier with a higher CADR since it means higher filtration capacity.

4. ACH(Air Change per Hour)

This refers to the number of the times the air purifier cleans the entire room’s air in one hour. If an air purifier that has 5 ACH, it means that the air in the room will be filtered every twelve minutes.

5. Avoid purifiers with negative ions, photocatalytic oxidation, UV lights

Avoid air purifiers that have either of the three specifications as these can potentially release ozone as a by-product. Ozone is harmful to the lungs and is known to lead to more incidents of asthma attacks and other respiratory problems.
