Product Description:
The QuietClean tower air purifier offers superior air cleaning power with permanent filtration. The high efficiency permanent filter removes up to 99% of airborne particles such as dust, pollen, smoke and pet dander, returning cleaner, fresher air to your room. Compared to ionic air purifiers, the filter from the HFD-110 captures 12 times more pollutants+. A powerful but quiet fan pulls air into the unit, circulating and filtering the air in your room several times each hour. The permanent filter is easily rinsed clean in water, requiring little maintenance and no expensive replacement filter costs. An automatic filter clean indicator will even remind you when its time to clean the filter. Easy-to-use, touch button electronic controls

Rating : - Ionizer
My bf and I bought this air filter specifically for the fact we both have asthma and wanted a nice air filter that not only cleaned the air, but would not create ozone. No where in the reviews did it say that it was an ionizer so we bought it. We had it on for one night, it did a great job cleaning the air and was quiet but when I went to go break down the packaging, I noticed teeny tiny print on the bottom of the box that said: warning: includes ionizer that produces ozone. do not use if you have asthma.

We were both quite upset that we didn't see this warning on Amazon before we bought it. Had to return it! False advertising!
