Air purifiers make the air inside your home healthier to breathe by trapping tiny airborne particles that cause odors, irritation, and allergies. Most air purifiers use a fan to suck in the polluted air and push it through a series of filters. The air is then cleansed of odor and pollutants before being released back into your room. 

With so many different air purifiers on the market, it can be challenging to find the best ones. But one of the simplest ways of tracking down the highest-quality air purifiers is to read customer reviews on Reddit. Here are the top four purifiers users are raving about.
