Tips for Choosing an Air Purifier
This is the first thing you need to figure out when you set out looking for an air purifier. If you want a purifier for your bedroom or study, most entry level ones will work.
However, if you want a purifier for a larger room you will have to spend more and get either one large purifier or two small ones. Almost all purifiers give details on their effective area to help you decide.
CADR stands for Clean Air Deliver Rate and it is the international standard for calculating how effective an air purifier is. It is calculated as per a room’s area and helps identify how quickly the purifier will be able to clean the air in a particular room. In simpler terms, the higher the number of CADR of an air purifier, the faster it will clean the air.
Filtration system is the core element of a purifier. Most entry level air purifiers come with a three-layer filter system. It includes a pre-filter, a Hepa filter and a carbon filter which work to remove pollutants, dust particles and odour. Some purifiers combine these three into one filter unit, others offer three separate filters which can be individually replaced.
Most entry level air purifiers come with a basic LED indicator system for air quality—avoid these if possible. The newer models of purifiers come with a digital display that shows you the actual air quality level in your room. This makes it easy to fi gure out when you need to run the purifi er at maximum level and when you can turn it down.
The majority of air purifiers do not come with a remote control. So every time you want to change modes or enable/disable a function, you will have to get up and do it yourself. This is why we recommend that you opt for a purifi er that comes with a remote. A few smart air purifiers connect to WiFi and you can enable/disable them via apps.
Your air purifier relies solely on its filters to do the cleaning. So most fi lters would run out in a few months and would have to be replaced with new ones. This is a recurring cost. It would be best that you fi gure out the cost of replacement filters beforehand. This way you do not end up paying the price of new fi lter replacements frequently.
