I have had this Hunter Air Purifier system for many years. It is quiet, has three flow selections, and also acts as a personal fan. It has been running trouble free for all these years and I highly recommend this unit over products that sell for a lot more... Only negative consideration is that their replacement filters are not cheap ($25) for a pack of two and hunter should consider reducing the price. Here's a tip, vac. the unit and filter and it doubles it's life expectancy! GREAT UNIT!

MY TEENAGER HAS RE-ACTIVE AIRWAY DISEASE, A LIFE LONG MISERY TO BREATHE. THIS PRODUCT ALLOWS HER TO SLEEP IN PEACE AND IMPROVE HER LIFE. A MUST FOR BREATHING AILMENTS. A GREAT PRODUCT. WORTH EVERY PENNY!

I love my air purifier! It has help SO MUCH with my dust allergies!
