The deteriorating air quality in the city is making difficult to breath. The air quality indoors isn't much different. "Your indoor air is often much more polluted than the air outside. Since we spend most of our time indoors these days, our exposure to poor indoor air quality puts us at risk for a number of ailments, including allergies, asthma, and respiratory issues", explains Gulbahaar Taurani, Business Head - PhilipsAir Purification, India. While there isn't any short-term solution for improving the outdoor air quality, you can breathe pollution free air when indoors.
If you are planning to buy an air purifier, consider a few things including the room size, the clean air delivery rate (CADR), air changes per hour (ACH) and the type of filter in the purifier, among other things. CADR is affected by room area and height. The CADR should ideally be two-thirds of the room size. So, for a room measuring 300-350 sq.ft., a CADR of 200-250 cubic metres an hour (m3/h) is preferable. Higher the CADR, better the air filtration capacity of the air purifier. he type of filter is yet another important factor - a HEPA (high efficiency particulate air) filter can filter up to 99.9 per cent airborne particles of upto 0.3 microns in size; activated carbon in combination with a HEPA filter can remove odours, too. Also consider the operating cost, which is the cost of replacing the filter at the time of the purchase. Taurani further adds, "Avoid purchasing technologies which use ionization, photo catalytic oxidation or produce ozone into the home environment. UV sterilisation is also not recommended for indoors as its best used when human presence is not there."
