Air Purifier Buying Guide

Air purifiers are available in various shapes and sizes with numerous features. While you might be attracted to a set of air purifiers you should not only go on the looks, instead, you should also look at the specifications and features to decide on what purifier to purchase. Here we will be listing some of the most important things that you should consider while purchasing air purifiers.

Good air quality sensor

One of the most important things to look for in an air purifier is onboard air quality sensors. Using these onboard air quality sensors, the air purifier can automatically kick up the filtration system when pollutants are detected. Also, purifiers that offer sensing capabilities will relay information to you about the air quality, making you aware of how efficiently the air purifier is working.

Some air purifiers also come with multiple sensors and a display to make the user aware of the types and concentration levels of particles, thus helping users in understanding the air quality inside of their homes. Some of the major sensors you should look for in air purifiers include PM2.5, PM10, VOC and NO2.

Method of filtration

There are multiple filtration methods that air purifiers use to purify the air. Some of the popular methods of filtration include ultraviolet light, activated carbon, air ionisers, and HEPA.

Ultraviolet light uses electromagnetic radiation to destroy bacteria, viruses and mould. Activated carbon filters react chemically with pollutants to clear smoke, odours and gases from the air. Air ionizers work by sending out a stream of charged ions to attract dust and allergens. And HEPA purifiers work by trapping pollutants and fine particle across a range of different sizes. You should look for purifiers offering a combination of these filters like HEPA filters with activated carbon. You should also look for air purifiers with a vacuum-sealed filter to ensure that the pollutants are not released back into the air.


The airflow of purified air is very important. The air purifier you get should be able to project purified air to every corner of the room. This is important so that the whole room is purified and not only one spot leaving some of the areas in the room with pollutants.

Year-round use

While air purifiers are a great addition to one's home, you should also consider that the air purifiers should be used year-round. This is why we recommend that you get an air purifier that doubles up as a heater or a humidifier so that you can comfortably continue to use the purifier in all seasons.
