: :These Hamilton Beach 04163 HEPA air purifiers have a digital display, monitor the air quality in a room, and are a triple threat to allergens with 3-way filtration -- a carbon pre-filter, HEPA filter, and UV germicidal light. Good for office, kitchen, family room, bedroom or basement rooms up to 350 sq. ft. Enjoy HEPA filtration for 99.97% of particles as small as .3 microns including dust, pollen and smoke and a filter change indicator on the air purifiers controls. AirSmartsensor displays air quality (poor, fair, good) for the room on the control panel. Four fan speed settings include: WhisperClean - use for quiet, nighttime operation or for constant low-speed filtration; Medium - provides a higher fan speed to quickly filter dust, pollen, smoke, etc.; QuickClean - provides cleaning during acute needs; Auto - functions with the AirSmart sensor, and automatically selects fan speed depending on the air quality detected. This is the normal setting for continuous use.
Review:Equipped with a UV germicidal light to help kill airborne microorganisms and a three-speed fan to continuously circulate air through two filters, this portable air purifier removes smoke, pollen, dust, animal dander, dust mites, molds, bacteria, viruses, and odors. Helpful for asthmatics, allergy sufferers, and cold/flu patients, the purifier contains a true HEPA filter that is at least 99.97 percent effective at trapping tiny particles; a prefilter reduces odors. A digital readout displays air quality (good, fair, or poor), and the fan can be set to automatically adjust speed according to air-quality needs. Digital indicators show when filters need replacing. The purifier measures 19-1/2 by 14 by 8-1/4 inches and is recommended for rooms up to 350 square feet. Filter replacement is simple: open front, remove prefilter and/or HEPA filter, position new filter(s), and close. The purifier carries a three-year warranty against defects.

Great product!
We have purchased Hamilton Beach products several times in the past two years (for our daughter who has allergies), and this model is the best yet! Not only does it clean the air in the room, but it is also soothing when she becomes fussy! *** If you purchase it, just remember to change the filters when required. Also, if you will travel with it, I recommend packing it in bubble wrap before placing it in a suitcase.

Doesn't solve cat allergies
I recently bought the Hamilton Beach Air Purifier to improve the air quality of a room where 2 cats are living. I am allergic to cats so I was hoping this filter to at least improve the air quality of the room and reduce my allergies. After a full week of use on average speed, I still can't stay in that room for more than one hour. When I use the air purifier on automatic, the sensor says the air is perfectly clean. I did not observe any improvement of the air quality. Maybe it works for other types of particles, but it doesn't solve cat allergies issues.

Works great. Quiet setting is really quiet.
I have had this unit for over a year. We turn it on only when we perceive a problem and now that I give the cat a clip each Spring and Summer we don't seem to need it so often. In the winter when the doors and windows are closed we use the unit to remove cooking odors which seems to work well. It is nice looking unit, designed so that it still works if pushed up against a wall.

Noisy but good.
Great quality and features for the price. The air quality sensor works well. It does not blow air out the front as you would expect, but out the top on the right side because the fan inside is hamster wheel style. It is nice not having to guess when to change the filter. The whisper setting is much louder than you would expect. I like white noise when I am trying to sleep, so this was not much of a negative factor.

Have had no problems with this unit
I purchased this air purifier over a year ago and have been running it EVERY DAY since then. My wife and I use it on medium as 'white noise' while we sleep and enjoy the benefit of it cleaning the air in our bedroom. We don't really have allergies or anything so we can't say that we can tell it has made a difference in the air quality, which is not that bad to begin with, but from the look of the wads of dust in the carbon prefilter shows the true story of what it's doing for our air. We recently got a puppy and would love to purchase a second unit for the area she sleeps in, I'm sure we'd definatly notice a difference there, but it's hard to justify paying 144 for it when i got the same model 4163 for only $99 well over a year ago. As for it being loud as some would claim, perhaps if you are really sensitive to noise but only on high does this thing make a lot of noise in my opinion. Overall I'm very happy with this unit and would recommend it to others.
