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 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.

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 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 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.
