 "99% perfect" 2009-01-06
By Jeffrey the Barak
I will echo all of the positive reviews seen here and add some extra information.



Reading the various reviews, people may be worried if they are finding the right model in the stores, and if the model inside has the lifetime HEPA filter or not. The box may say permanent or it may say something else, with a sticker that says "permanent filter inside". This is all you need to know. I don't think it's even possible to find inventory that still contains the replaceable filter.



As a torture test, we put our unit in the kitchen when we roasted greasy chickens over the 2008 holidays. This usually stinks out our apartment for a week, and it still did. It was too much greasy smoke for the Honeywell. Worse yet, after moving the unit back to the office, there was a roast chicken scent for another 5 or 6 days. I was about to replace the one month-old carbon pre-filter, but then it finally wore off and now the unit seems as fresh as new.



But roast chickens aside, the difference in air quality in the office and bedroom (we move this unit around daily from home to office) is very impressive. Dust is down, chemical odors are gone, (I sell glue and solvents), and the computers are staying clean. (When we had an ionic breeze, the electronics would attract more dirt, and the air would be dusty, now the air is clean and so is the equipment).



I did so much research before buying this and I am very happy I chose this unit. I run it on low for about 16 hours a day, occasionally on high after making the bed in the morning, and only turn it off at night (for silence).



I'm considering getting a second one, but then its so easy to move...

Update: March 11th 2009, used every day since December 11th (3 months) and still working perfectly and very effective, without any filter change or vacuuming. The only odd thing is that the filter indicator lights seem unchanged so maybe they don't work. I don't know, but I will try to wait another three months before changing the pre-filter and vacuuming the permanent HEPA filter.

I just want to say if you want clean air. Get one of these. Very loud on the high setting but after a day or two it becomes white noise and you would not even notice. I am about to buy another one for the bedroom.

 "not sure" 2008-01-20
By Sophie (Kandahar Afghanistan)
I'm not too sure what to say...is it bad? no...is it great? no. I bought this to help purify the air in my office here in Afghanistan. Let's just say to start that is no easy task!! The unit seems to be functioning well enough but it's a little on the loud side and it really drops the temperature in a room. It has not had any issues and seems to be working...as I said, the air here is terrible to begin with so it's hard to say if it's really making a dent. I'd like to think it is.

 "Fair and not-so-quiet" 2009-07-14
By Hsiang-kuo Yuan (Durham, NC)
This is a rather bulky air purifier that has an advantage of having re-usable HEPA filter. However, although it generated loud noise even under low power setting, it's not as powerful as expected. Its purification efficiency seemed similar to my small non-HEPA air purifier. Compare to a 3M Filtrete airpurifier that I have, this model has similar noise level but less purification efficiency. Perhaps the difference lies in airflow or filter design.

 "Works but falls short" 2009-07-12
By Rex (USA)
Good room air cleaner but limited to about 10 X 8. It runs quietly but does not appear to have as much air flow as I would like and the filters require frequent replacement. I would be happier if the unit was priced around 75.00 for the cost I expected more. It works fine but for the money fails to fully meet my expectations.

 "Large paperweight" 2009-07-07
By Iowadad (Iowa City)
Judging by many other reviews, what happened to me seems to be quite rare, so make of it what you will. But our Honeywell just completely stopped working.



I bought this primarily for my wife's allergies and we used it for a couple of months during the pollen season. It worked as others have described. It was put away for several months and then plugged in again and it's simply dead. There is no response at all even though nothing happened to the unit and it simply sat dormant for a few months.



Hate to give it the rock-bottom review but there was no reason for this thing to just stop working. I kept thinking there must be a simple reset button on it or something but it seems fairly simple. The electronic controls just quietly passed away while sleeping, it would seem.

 "Silent Comfort - says it all!" 2009-07-03
By Scott J. Sedei
This is a fantastic air purifier. I bought two of them to replace Oreck Tabletop XL Professional Air Purifiers (a costly waste of money). I use one of the Honeywell 18155 SilentComfort Permanent, True HEPA Air Purifier in my bedroom and leave it on the high setting at all times. On this setting it is very quiet and doesn't disturb my rest at all. On the lowest setting it is so quiet I can barely hear it. Since placing this unit in my bedroom I sleep straight through the night and I wake with clear sinuses and no congestion.



The second Honeywell is in my living room. My living room and dining room share a large combined space and this unit is small for the area. Because they are quiet I plan on getting another unit for the dining area - two of them should handle the area well.



I do a thorough dusting and cleaning every week, so I was shocked at the amount of dust, cat hair and "stuff" that was trapped in the charcoal pre-filter the first time I cleaned it, and in subsequent cleanings. I don't smoke, I do have three cats and have allergies to dust and pollen. These purifiers are truly a life saver!

 "Does not deliver" 2009-06-23
By Susan Benson (Ashburn, VA)
After much research, I puchased this filter for my bedroom to help control dust allergens. After several months of running the unit nearly non-stop, there has been absolutely no reduction in dust. I vaccuum every week and still have to hand-dust, and my bedroom is not that large.



What I do like about the unit is that it is portable, so I will sometimes move it to the kitchen or basement to help control odors.
