Hunter 30057 11-Feet by 13-Feet Hepa Tech Room Air Purifier for Small Rooms

I have owned this air purifier for about 5 years and it's still going strong, it's also not any louder than it was the day I bought it. The noise it produces is similar to a fan on a low setting, kind of a white noise so to speak. The filters are reasonably priced if you find them on sale-they are currently on sale for 29.99 (reg 39.99) & I replace them every 6 months. The carbon pre filter is much cheaper when bought from your local home improvement store, they sell sheets of carbon that you can cut to fit.

Great product, and helps breathing at night. Now I have 3 Hunter HEPAtech air purifiers in different sizes based on the room size. One large one handles the complete first floor.

I've had this purifier for about 4 months now. It's been great! I have a cat in my small apartment so I use it to clean the air of cat litter dust and dander... because of the litter dust, I've already had to replace both the pre- and HEPA filter way before their time, but I guess that just means it's working. The pre-filter can can also be vacuumed or shaken out to clear the dust. The noise is minimal, but I'm used to having fans running in my room already... I would definitely recommend the Hunter 30057 as a cheap HEPA purifier.

Also note that it takes a while for the initial plastic smell of the parts to fade, several weeks in my case. If you have a sensitive nose, you may want to look elsewhere.
