How Quiet is Honeywell's QuietCare HEPA Air Cleaner? The Honeywell QuietCare HEPA Air Cleaner has been specially engineered to provide ultra quiet high speed operation. Independent testing shows that the QuietCare HEPA Air Cleaner is quieter on high than other HEPA and Non-HEPA air cleaners of similar performance. On higher speeds, air cleaners circulate more air through the filter, which may provide improved performance in all room sizes.
How Can You Measure Sound? Sound can be measured in Sones. Sones take into account a sound's loudness (measured in decibels) and its frequency (how high or low it sounds) as perceived by the human ear. This is important because the human ear hears sound differently than do sound measuring devices, as certain frequencies of sound are more pleasant for us to hear than others. Using Sones, it is easy to compare how loud an appliance is against another - a Sone of 10 is half as loud as a Sone of 20.
The American National Standards Institute standard, ANSI-S12.31-1990 is most suitable for measuring the sound of small appliances.

Amazon.com Review: This portable air cleaner is recommended for filtering the air in a closed room as large as 168 square feet (12 by 14 feet). As it continuously circulates a room's air--about six times per hour--it employs two filters to remove smoke, pollen, dust, animal dander, dust mites, molds, bacteria, viruses, and odors. Especially useful for asthmatics and allergy sufferers, the cleaner contains a true HEPA filter that is at least 99.97 percent effective at trapping extremely tiny particles (as small as 0.3 microns) while a prefilter reduces odors. Honeywell's IntelliCheck system permits monitoring the filters' lives. Each filter has a button. Pressing a button activates a light, which blinks or shines steadily. One blink indicates that the filter has lots of life remaining, two blinks means less life, three blinks means even less, and a steady light indicates the filter needs changing. The HEPA filter lasts one to three years; the prefilter, three months. Filter replacement is simple, and replacement filters can be ordered separately. The air cleaner has three speeds, and all are exceptionally quiet for an air cleaner this large and powerful. It carries a five-year warranty against defects. --Fred Brack
