AP-230PH Air Purifier with PlasmaTRUE™ Technology
The motor is very quiet on all the settings, but, there is a high pitch whine on the low and medium settings so I'm not using the auto feature. I have it set on high all the time. This is fine since the fan is very quiet but I do lose the auto feature.

Step Up from Basic Air Purifier
I have two small, basic HEPA filter air purifiers that seem to clean the air quite well. Were are currently experiencing dust storms due to a drought. Even though our house is well sealed, small amounts of dust penetrate around the doors and windows. I do not like the smell of dust or the idea of having extra pollutants in my house. Two of the basic air purifiers are being used in the upper floor. The Fellowes AP-230PH is used in the family room in the basement. I like the extra air purification beyond just the basic HEPA filter provided by the addition of a carbon filter, the sanitation feature and the PlasmaTRUE technology. The digital displays of room air quality are another nice feature. I also like the ease of changing the filters and the easy reset feature of the "change filter light". Of all the air filters in the house I have a higher level of confidence in the Fellowes AP-230PH because of the extra features, and it is the quietest one I have owned.

Quieter than a whisper!
This was a Christmas present for my wife, who has a fairly severe dust allergy. A complicating factor is that she works 'graveyard shift', so sleeping soundly through the day is critical. When I first set up the unit, I had to double check to make sure it was actually running - kudos to your engineers for designing such a quiet device. I have never had any kind of appliance that was this quiet. We both had an undisturbed sleep today, and woke without stuffed up sinuses. I only wish that I had purchased this sooner. We are both looking forward to better days ahead. Thank you!
