5.0 out of 5 stars
Thoroughly Cleans the Air for Better Sleeping,
By SDG "SDG" (Washington, DC USA) - See all my reviews
Amazon Verified Purchase(What's this?)
Have used several less expensive HEPA filters in the past with less than stellar results - the Blueair 501 cleans the air more thoroughly - I would wake up occasionally coughing before (most likely due to pet dander) - have not had this happen since running the purifier at night on setting "4" of 5. I also have a neighbor who's second-hand smoke sometimes drifts in through the pipe fittings - the smell has disappeared, too. This unit is more expensive but it's worth it - am very satisfied!
