Before we purchased our Honeywell HEPAClean Tower Air Purifier, we spent bookoos of money on worthless allergy medications to absolutely no avail. Now, with this air purifier, we do not spend nearly as much money on allergy medications or doctor's visits. Everybody is healthier, happier, and better off! Ease of Maintenance This air purifier is very easy to maintain. I love it! Dust/Allergen Removal We always had really bad allergies around here, but not now! I could not believe the difference my air purifier has made! We have been staying healthier, breathing better, and everybody in the house loves it! Filter Availability You would not believe the stuff you breathe in every day! It really is insane! Durability Not bad at all. I hope it lasts for years to come! You should try it too! Effectiveness One of the most effective air purifiers I think I have ever owned. I just love it! Design I love the design of this air purifier. It is very nice to look at and still does a great job too.
