 Air Purifier buying guide: How to buy the best air purifier for air pollution?

With increasing pollution levels, having an air purifier in our homes has become a must to counter the harmful effects of the soiled air. With minimum industry standards in place, choosing and buying an air purifier is a tricky task. Costing between Rs. 8000 to Rs. 1 lakh depending upon the functions, it is very important to go through the specifications of each model before buying an air purifier for your home. Here is a guide that considers the things one must know before buying an air purifier.

What you must know about your environment and the air quality index?

The air quality level index considers several factors, which cause breathing problems other illnesses. Eight of these-- Nitrogen dioxide, Sulphur dioxide, ammonia, lead, carbon monoxide, ozone, and particulate matter (PM2.5 and PM10) have significant contributions in deciding the amount of pollution in your surrounding air. Further, the particulate matter is classified based on its size in micron.

Understanding the air purifier related jargon

One needs to look at the following specifications while choosing the ideal indoor air purifier. These terms would help you choose the best budget-friendly air purifier that also matches all your health requirements. For instance, choosing air purifiers that use filters instead of ionizers that can be harmful to some people.

HEPA filter: Make sure that you buy a purifier with a genuine HEPA filter, as that is an international standard. Going by the product engineering, the more filters an air purifier has, the better suited it is for more polluted air. The top 10 air purifiers in India come with a HEPA filter that removes the suspended particulate matter like dust, pollen, soon, smog, and liquid droplets that contaminate the air. 

Nowadays, most air purifiers also contain a pre-filter that removes some large particles (10mm in size), that HEPA often fails to remove and consequently increases the life of the HEPA filter.

Clean Air Delivery Rate: CADR is the measurement of how fast an air purifier can clean up the air in a specific area. It is measured in cubic meters per hour and it determines how effectively the air purifier is cleaning the air in the room. Keeping this specification in mind, you can choose the air purifier best suited to your location and the surrounding environment.

Effective size or Coverage area: This is an important specification as it helps one determine how well the chosen purifier matches the focused area. One must always choose the air purifier that has the capacity to cover a larger area than the space it is going to be used in. This will ensure that the air purifier uses less energy while cleaning more effectively. One can ask for the CADR and the Effective size figures from the
shop-keeper and/or the manufacturer.

Air changer per hour: This figure is important with respect to the consumers’ health. It’s basically the number of times per hour that the purifier is able to filter all the air in the room. For instance, an allergy and asthma sufferer requires at least 4 air changes per hour, which means that your chosen air purifier should be able to clean the room at least once every 15 minutes.

Apart from this, the best air purifiers also feature some other functions like -deodorizing filters, ECO mode, etc. to match the modern consumers’ needs. Next time, you think of buying an air purifier keep these elements in mind and ensure that you and you're loved to get the freshest and healthiest air possible.
