Review Content good stuff i love it and have not gone by a nite without it good air purifier good machine Simply the best air purifier ever! This is quite simply the best air purifier we have ever owned. Yes you will need to replace filters from time to time but we feel the value of its effectiveness more than validates the slight increase in cost of operation. It is a beautiful unit; very sleek and extremely quiet! My wife and I are allergy sufferers and pet owners and this product has made sleeping soundly much easier. Fantastic Air Purifier - very quiet! I recently moved into a house where the previous owners had multiple cats and dogs - the furnace was literally coated in animal hair. I was having to dust every day and 5 minutes later you couldnt tell. I got my ducts and furnace cleaned and purchased this air purifier and what a world of difference! It is very quiet yet effective and light and compact enough it can easily be moved between rooms. Love it! Happy I have two cats and a big house on a lake. I keep litter constantly clean and the house as well but I just want a bit extra air circulation. I have only had the unit plugged in for 12 hours and can already notice a fresher air quality? Think I will love it! MM Hepa not the ionic comfort It doesnt capture particles smaller than .3 microns, but no hepa filter does. For a HEPA filter it is one of the most stylish, and best in its class.
