There is no doubt that air pollution has turned into a big menace for today’s population and if you’re living in a big city like Delhi, you’re more likely to get exposed to severe levels of air pollution. But it is not only the air outside our homes that is severely polluted but the air inside our home can pose a grave threat to our life. Yes, several studies have revealed that the air inside our homes can be 10-30 times more polluted than the air outside our homes. And when it comes to combat the rising pollution, investing into a room air purifier seems a lasting and effective solution. Let’s know why and how you can get the best air cleaner for your home.

What is an air purifier?

An air purifier is much like a water filter as it receives polluted air inside a room and throws cleansed air instantly. Just like a water purifier has several layers of filters, an air purifier features different types of filters that ensure utmost cleansing of the air. For example, these air purifiers for home can filter out PM 2.5 and PM10 air-borne pollutants. With so many pollutants prevailing in the contaminated air, this kind of air purifying machine has been a need of the hour.

How to choose the best?

Being a thumb rule, air purifiers are found to work best with shut doors and windows—so that they’re not having to continually filter dirty air. The filtration capacity should be matched to the room size, generally measured in square feet (multiply the length and breadth in feet). After testing out a group of purifiers, experts discovered that one of the great features to have is an in-built humidifier.

A steadfast water tank will help you introduce humidity as and when required. Other features you can think of are a timer, sleep mode (quiet operation), child lock and air quality monitor (which turns from red to green to display current quality of air). If you’re going to buy only one unit, begin by putting it in your bedroom and buy more if you notice the difference.

Given the size of room, an air purifier will generally take between 15 to 30 minutes to cleanse the air and will keep recirculating while on. It should be kept on as long as you’re there in the room – they normally consume between 20 to 50 watts, so it’s not a big draw on your power expenses.
