Bests & Worsts Reviews from Amazon

This air purifier was delivered on June 24, 2017, just a little over a month ago. I have a dog with severe allergies to dust (lucky me right?) and I decided to try at home treatment before putting him on steroids. I put this purifier in a medium sized room right next to his kennel, and since having this, his allergies have cleared up. I attached before and after photos of both my dogs' hives and the air filter after just one month. This product is astounding.
