This product does a great job of removing allergens from my house. It is quiet I am really enjoying the unit and it is working very well for me. I have severe allergies to dust and pet hair (I have 2 cats and 1 dog), and since I've been running the  air purifier, I've noticed that my allergies are not bothering me nearly as much. I like that the unit is so very quiet, and that it is simple to operate.
