We’ve all become more health-conscious over the past year. The pandemic has taught us to wear masks in public, frequently wash hands, and keep our surroundings as clean as possible. Since the COVID-19 virus is airborne, it’s only logical that we also keep the air in our homes and workspaces clean. Although there is no substitute for clean outdoor air, you can get the next best thing with the use of air filters.

Top 5 Air Filters

What are the Top 5 Air Filters for your Home and Office in 2021?

There is a reason why these devices are almost always sold out. They are proven to effectively remove harmful air pollutants and they even offer some protection against the COVID-19 virus.

There are hundreds of air filters available on the market depending on your budget, room size, and health needs. We know that picking out the right one can be a daunting task especially if you know so little about the product. An important note to consider is the air filter’s CADR rating. CADR or clean air delivery rate measures the purifier’s effectiveness according to room space and the volume of clean air it can produce per minute. According to the Environmental Protection Agency, for example, a room with an area of 300 square feet requires a minimum of 195 CADR.
