The thick blanket of smog over Delhi skies doesn’t seem to leave and it’s time when people should look towards alternative ways to ensure healthy living. As breathing is intrinsic to our lives, it is necessary to create a healthy breathing environment at least in our homes and offices where we spend most of our time. And the best way to make this possible is to look for effective air purifiers for home and offices. This could be an easy and effective way to tackle rising air pollution at least to some extent.

At a time government is struggling to define a long-term strategy to tackle air pollution, investing in air purifiers is certainly a positive move to seek some respite. Let’s look how you can choose the best air purifiers for home.

All latest air-purifiers come with High Efficiency Particulate Air (HEPA) filters. These filters are usually appraised to trap particles as tiny as 0.3 microns –, the thickness of a strand of human hair is about 50-150 microns. Thus, air purifiers for home with a HEPA filter should be able to block out both PM 2.5 (particles that are 2.5-10 microns in diameter) and PM 10 (10 microns or more in diameter) particulates. To define clarity against probable confusion over what the acronym ‘HEPA’ denotes, it is better to ensure the air-purifier references having both a ‘True HEPA filter’ and a rating of at least 0.3 microns.

The size of an air purifier is another element that affects the effectiveness of the device. It regulates how much air the purifier can circulate, and the amount of air gets in at any given time. The best way to deal with this is to be on a safer side. For example, if you’ve a room that is 300 sq feet in size, it is best to look for air cleaners for home that can handle at least 400 sq ft.

Another aspect that demands a careful look is the Clean Air Delivery Rate (CADR). This refers to the amount of air that can be purified of all its particles, defined in cubic feet per minute. In general, there are three CADR ratings, one each for Smoke, Pollen and Dust, as these three particles tend to differ in size and therefore are filtered out at changeable efficiencies.

While browsing through the popular air purifiers for home, do give careful consideration to all the above mentioned elements for a fabulous deal.
