When I first decided to buy an air purifier, I thought it would be simple: pick one with good reviews, plug it in, breathe out a sigh of relief and breathe in some beautifully pure air. The reality wasn't quite as simple.
What I wish I knew before beginning to look for the best air purifiers is just how many factors actually affect how well it works in your home, from the type of filter you use to where you place it. There are even air purifiers that are much better suited to allergens and others designed for dust. Then there are others that just make a lot of noise and look pretty.
