I bought this air purifier for my salon suite. It’s a small area 18x9 feet, but was getting so dusty and it felt very stuffy a lot of the time. Especially after using hairsprays and products. But now after having this for a month it’s 100x better. My clients and I feel more comfortable, and I don’t have to blow my nose every five minutes (which in the middle of the covid pandemic is not very convenient). I am now thinking about purchasing one or two for my home.
