Worried about air pollution? Here's how to buy the best air purifier


The type of filtration the air purifier uses is one of the most important considerations before you purchase the product. Look out for one with a HEPA filter and NOT a HEPA- type filter, the latter being there in cheaper products. High Efficiency Particulate Air (HEPA) filters are proven to eliminate 99.97% of common airborne allergens sized at 0.3 microns and larger. It is also a standard that is tested and certified.

Activated carbon filters are also being preferred. For those, who are willing to have high-end air purifiers in Delhi that completely deter the odor, smoke, and volatile organic compounds can go in for activated carbon filters. These are highly absorbent filters that are also easy to maintain. But they also have a shorter life span.

UV technology air purifiers kill harmful bacteria, and viruses. But if you purchase the UV air purifier, make sure the system does not produce ozone (high-concentration)

Negative Ion purification comes with  inexpensive filters that help promote deep sleep but again releases ozone into the air which is harmful and hence best avoided

Pre-Filters, like foam and non-woven polyester, eliminate large particles like pet hair before the next level of filtration and are good to have in the air purifier. You should look for an ideal combination and types of filters that are most suited for your individual needs
