I have other ionic air cleaners, as well as one that requires a filter. This air purifier is quiet and due to its compact size, can be placed off the floor on a bookcase, dresser top or top shelf which makes it optimal for space-saving and placement. I don't particularly like the noise from air filters and they have a tendency to keep me up.

After spending many dollars on replacement filters and new air cleaners when the filter is no longer made or easily available, this is a welcome addition with a permanent cleanable filter. I bought two of these, one for my bedroom and one for the living room. Set on low all of the time, it is great as it just sounds like a little white noise and is not noticable most of the time. The optional ionic on and off switch, night light, as well as the automated light indicating that the filter should be cleaned is a BONUS besides the low price. So far, I am enjoying cleaner air in an old dusty house with 3 cats and 2 dogs...

I have bought the Sharper Image ionic breeze for the bathroom and find it hard to clean and hope that when I have to clean this filter. Good value for the money.

This is my 2nd air purifier - the other was a comparable model by Holmes. I learned from my first air purifier that you really have to leave it on all the time or the revolving motor will collect dust, not work as well or as quietly. If I don't want it on constantly, I just put a clean towel over the top to prevent any dust/dirt from building up.

The noise level is acceptable to me, in an 8x10 room. I usually leave it on LOW, which sounds a bit like a fan on low speed, but MED is good too - it has a nice white noise effect. I only put it on HIGH if there's a bad smell or lots of dust floating around (for whatever reason). HIGH is a bit loud for my taste. This machine tends to rattle a bit as it sits on my bureau, but a small towel underneath it took care of that problem. Also, give it time to warm up when you put it on. It starts off slowly, but works at full speed within a few minutes.

I have allergies and noticed a difference immediately when I got this model. My symptoms have improved greatly, even with 3 cats in the house. I would recommend it to anyone who has a small space, doesn't want to buy new filters and is perhaps on a budget. Good machine at a decent price.

I brought this one recently to replace the sharper image's ionizer purifier, since I want something to shut off the ionizer -- the air has some smell from those ions.

This unit has three speeds. Another switch to turn on or off the ionizer.

The lowest speed can push enough air comparable to Sharper Image's high speed, without much noise. If no one talks in the room, you can still notice the sound. But if anyone talks or the TV is on, then you would not noticed the sound, even in a 8x10 room. Middle and high speed push 20-50 times more air than a Sharper Images ionizer purifiers. I wish it has a feature to push a button to boost the air flow to high speed for 15 minutes, then fall back to slowest speed...

For the price of a tank of gasoline, and free shipping from Amazon, buying this is no brainer....

I just returned this item and amazon took $12 off for restocking fee. So I decided to write a review now to share my experience. The unit is small, which is good because I could put it on a table. One small thing that annoyed me was that the unit actually moved little by little when it was on because it was vibrating. So I had to put it on a more rugged surface to keep it from moving.

The purifier worked perfectly fine for the first several days. It produced a humming sound, and it wasn't loud. I could definitely have it turned on while reading without being distracted. The high setting was quite noisy, but still it was within reasonable range of noise. Bottom line: if it were like that all the time, I would've kept it.

Unfortunately, after several days, the unit became extremely noisy and produced a noise like popping popcorn in a microwave, even when I set it only on low. Then the noise became intolerable and I decided to return the item.

Perhaps it was because I got a defective unit or what, I don't know. But before buying it, I read some reviews on amazon indicating that the unit is indeed very noisy. Some reviews, however, suggested otherwise, that the product is excellent. Given the mixed reviews, probably the risk of getting a very noisy purifier like mine is not extremely small. Hope this is helpful.

This Honeywell HHT-011 tabletop air purifier turned out to be just what I needed. It sits on a dresser in the bedroom. It is very stable, does NOT shake or vibrate, but produces a kind of "white noise" that is amazingly conducive to sleep (you can barely hear it on the lowest of the three speeds)we keep it on the medium speed. The air is cleaner, we no longer sneeze upon waking, and I don't need to dust as often. One of my main reasons for buying this product was that it has a permanent HEPA filter which can be cleaned and reused. (Our PREVIOUS air purifier was large-taking up too much floor space, it was too noisy, it was an electricity hog, and you needed to buy a new replacement filter as necessary - costing way too much to run.) THIS PRODUCT is compact, powerful enough to keep the room fresh and clean, easy and not expensive to maintain. I am very satisfied with this purchase and would highly recommend this air purifier.

I might buy a second one for my home office. As another reviewer mentoned, it is a little noisey on high, but the second setting (which seems powerful enough for my needs) has a pleasant hum that acts as white noice. It has a nice stable design...because it sets square and low, my cats haven't been tempted to try to push it over (some air purifiers looks a little too much like cat scratching posts). Instructions on how to use and clean are easy to follow. I'm not sure what the ionizer is supposed to do so I haven't used that feature, but so far I seem to be sleeping better with it running than I was without it, so I am assuming it is doing ts job. No complaints so far.

I bought the Honeywell HHT-011 through Amazon.com. At first all was well and I was very pleased with the air quality produced by the Air Purifier. I'm currently deployed as a U.S. Army Soldier in Iraq and the air outside is normally filled with dust, dirt, and smoke from Iraqis burning stuff. I live in a Containerized Housing Unit (CHU) and bought the Honeywell HHT-011 for my 12' X 8' room room. I tend to have sinus issues when the air quality is poor. The fan was a little loud, but tolerable - I just had to crank up the TV or IPOD. The front grill did not fit snuggly on the unit and reflects on how the unit is cheaply made.

However after about one month of use, the Honeywell HEPA Clean started to get louder and louder. It appears that the fan wheels are off center and have created a rattling noise. Now the Air Purifier is much louder and rumbles, rattles, and rolls. I've cleaned the filters (pre-filter and HEPA Filter) and the noise persists.

This purchase was very disappointing since it's a quality of life issue. But, you get what you pay for. Reading other similar reviews, this sounds like a quality control issue with Honeywell. Be prepared to spend more for a quality unit. Thanks.

Edit: Review appended at bottom with purchase of a second unit.

When I first purchased the "Honeywell HHT-011 Tabletop Air Purifier with Permanent HEPA Filter" I was ecstatic at the thought that allergens, dust and other air contaminants would be filtered, especially for the price. My room is extremely dusty so I needed some sort of solution and I hoped that this was it.

For the first six months the purifier worked efficiently, or seemingly so. I ran the it, as recommended, 24 hours a day nonstop. When I'm not home I ran it on the high setting (there are three settings), medium when I was around and low when I slept. I cleaned both the outer filter and inner HEPA filter regularly as a lot of contaminants were being filtered. I noticed a somewhat significant difference in the air quality of my room (11.5 x 8 ft) during this span.

After sixth months the purifier was rendered useless and actually made the air quality worse. The contaminant intake became less and less, the dust in my room begun accumulating faster (I still dust frequently) and the purifier's fan was blowing out unclean air - air that reeked heavily of dust.

I highly doubt that the HEPA filter is efficient forever and needs no replacement. It is charcoal grey and transmits little light when held to a light source (not sure if this is significant as compared to a car air filter test). I do as the manual suggests and vacuum it (more frequently than recommended) and I vacuum/wash the outer filter regularly. Another review mentioned that the purifier became filled with dust and grime over time; the same thing happened to mine, as evidenced when looking down the air vent. I tried to clean it out by blasting 180+ PSI of air with my air compressor, but it did nothing to help. The dust was very thick, almost lint like, and would not budge at all.

To make matters worse the purifier is fastened together by hexagonal security screws (I'm sure the average household does not have the required screwdriver). I recently bought the screwdriver and opened the purifier to clean it out, and found that the inside was a horrendous mess. Every surface and mechanism was layered with dust. The insides of the tubular fans were coated with dust as well. The task of carefully removing components to access all compartments for dusting was tedious and took some time. I've cleaned almost all of the contaminants from inside the purifier, but I am still very skeptical about using it again in fear that I will have the same problem again, perhaps in less time than before.

To sum it all up, this product was good for about six months until the inside of the purifier became festered with dust, and it was extremely tedious to remove it all. I'm not sure when this accumulation of dust began, or for how long the HEPA filter has been ineffective. The purifier does not filter all contaminants, instead sucking some into the interior and spitting it back into the air in my room.

With all of that being said, there are numerous positive reviews on this product; perhaps I am an unfortunate rare case. For the price I'd say it is definitely worth a try, but be cautiously optimistic if you decide to make the purchase.

Edit (March 3, 2011):

I bought another one several months ago to give it a second round. This second one is now in the same condition as the first. The fanned air again smells faintly of dust.

This time I unscrewed every piece and wiped the entire unit down. Everything inside has definitely penetrated the HEPA filter as I cover the top of the unit with a cloth when it is turned off to ensure no particles fall into the unit. I am disappointed that I again had the same problem.

If you decide to purchase this product I suggest you vacuum the HEPA filter weekly, and the outer filter every few days. I do not know if this will prevent you from having the same problem as me but it definitely could not hurt.

I like to sleep with white noise, and the air purifier that I had required a new $20 filter every 3 months, so I was happy to get this model with a HEPA filter that needs to only be vacuumed. The outer filter is washable. This model has an ionizer (which I've read some bad stuff about) - but it can be shut off/has a separate control.

Nice little air purifier -- perfect for a bedroom. The two lower settings are very quiet....but I like the high setting to drown out all those nighttime noises!!!

I have only had this air purifier for less than a week, but I am amazed at the results. After the first night of using this in my bedroom, I woke up and could actually breathe. My nose is normally clogged in the morning. Hopefully I'll be able to stop sleeping with nasal strips soon! Also, my dog has had watery eyes for a while and has been having a runny nose the past month or so. I didn't even think about the purifier helping with this problem. I happened to notice after the first night of using the purifier, her eyes were not wet around them like they normally are and her nose was not running. I also purchased a larger purifier to use in the living room, so hopefully that will help both my dog and myself for times other than while sleeping.

The noise isn't too bad, but I am used to sleeping with a humidifier. The high setting would be too loud to sleep with. I use it on the medium setting during the night and my humidifier is also on medium during the night. The humidifier is definitely louder than the air purifier.

I would definitely recommend this air purifier to others. I may even purchase one to take to my parents' house and use there when I stay overnight. My dad smokes and my eyes, nose, and throat are typically burning after one night. Maybe the purifier will help clear the air in the room I sleep just a bit. I'm sure my mom will also run it 24 hours a day while I'm gone to help with the smoke!!
