Pros: It seems sturdy enough even though I have to acknowledge the slight vibration that emanates from the machine. I don't know what I was expecting as it has been running for almost two days now.

Cons: I looked in the back and there are two venting areas and both sides have small pin holes in he back. In this machine on the right four small metal pins (think small nail) emerge and I have to wonder if this is the ionizer. There are holes on the left sides and I noticed reviews that talk about various incarnations of basically the same unit.

Other Thoughts: It leaves me somewhat saddened that the cost of extending a full set of ionizing pins can't be that great. I also get quite upset when I see ridiculous prices listed that are in no way representative of reality. I bought this machine for about $45.00 here because Newegg has decent shipping. I don't need to see some phantom price to be romanced into buying something I had intended on buying before I even came to the website. Here's me hoping me and my purifier have a long relationship otherwise I will let you folks know

Pros: I was right. The Honeywell HHT011 and the Honeywell 16200 are the exact same machines at different prices. The difference is removable vs permanent filters and some slight cosmetic differences in the chassis. If you check, the filters ARE the exact same size and are interchangeable. The vacuumable filter has a flat intake side so it is easier to vacuum. Other than that they are the same. Filters are about $18 at Home Depot.

The prefilter is the same foam they use on air conditioners and it washes well. Older versions of lhis stuff used to shred from one washing with detergent but this stuff seems to be appropriately durable.

After a month the pre filter had about 1/4 inch thick coat of dust on it. I wiped off the bulk, rinsed the filter from the inner side so the dirt would be washed out rather than in, and washed the filter with laundry detergent, which was what I had at hand.

Cons: These machines really are a bit overpriced for a simple filter with a fan. Esp as they are not going to last forever. The blower fans are not perfectly balanced. The machines vibrate a tiny amount because of this. No noise and the vibration is not bothersome, but, they will not last forever. Again, this thing is a pretty cheap solution to a simple problem.

Other Thoughts: The HEPA filter was dark from dirt but I decided that vacuuming could wait another 1-4 weeks. The pre filter does not seal perfectly so the HEPA filter is probably dirtier than it should be, but again, this thing is a pretty cheap solution to a simple problem

It does clean the air. Dust is a complex problem. I find bedrooms to be dusty by their nature. Lots of fabrics being heavily used. Also, I keep a window open almost all the time. That's why I'm looking for a cheap solution to a moderately vexing problem.

This seems to be the intersection of the cost benefit curve.

Pros: First, I'm very happy with this product. If you live in Chernobyl or Fukushima this unit may be a bit less than you need. If you just want to keep the dust away from the bedroom computers, it's fine.

Cons: Has no one but me noticed that the Honeywell HHT011 and the Honeywell 16200 are the exact same machines at different prices, the difference being removable vs permanent filters. If you check, the filters seem to be the exact same size. They recommend vacuuming the permanent filter. I've bought the one with the permanent filter. I'm going to buy one of the replacement filters and if it does fit, I'm going to try vacuuming it also. Marketing. That's the name of the game.

Pros: Low price for the amount of area the unit is advertised to cover
Filters are cheaper than most other units

Cons: Loud fan, even on low setting

Other Thoughts: After reading a lot of reviews for these types of products it really seems to be a hit or miss with people as to weather this really helps in their household. This could be because of it being used in too large of a room or possibly even the location in the room. It also could be that the unit is advertised to perform at its best with the fan set to its highest setting at all times. Unfortunately the fan is far too loud at the highest setting to be considered tolerable for most people.

Be that as it may, this unit has performed wonderfully in my small bedroom. Like a lot of other people who have purchased these, i also suffer from allergies from dust, pollen, pet dander and the such. Leaving the fan on the highest setting while I'm at work and then lowering it down when i get home seems to be sufficient and has noticeably cut down on the amount of dust that would normally collect on my desk.

Pros: i can Feel it Cleans The air

Cons: Super loud even on Level 1.
Louder than my AC

Pros: none

Cons: I bought this right before my son was born, and a little after a month after it broke. It wouldn't turn on anymore.. it just died. I was right out of my return period.

Pros: Kept things nice.. while it worked.

Cons: It stopped working within a months time.

Other Thoughts: Ticked off that I'm out of that money.

Pros: Got it on sale for $35 with free shipping, w00t w00t newegg. I wake up with far fewer boogers, dry throat etc and that's what I was looking for. It has 3 effective filters, washable pre-filter, the HEPA filter and then the Ionizer. I only run the Ionizer like every other day or so, because I have a PC in my room and I was told that it could dry up the air even further and induce Electro Static Discharge.

Cons: None so far

Other Thoughts: Haven't really had it long enough to notice less dust, but the house I am currently living in will definitely make that difficult even for the really expensive ones.

Pros: Not that good..

Cons: It's loud and it doesn't do that much good. I ended up buying a new one that is more expensive.

Pros: Gives some peace of mind. Makes me feel better that I actually tried to make the air in our home cleaner.

Cons: 1/ Noisy: Even at the lowest level the sound of the fans is very high, and the highest setting is only used when we go oiut
2/ Ionizer: Doesn't make a noticeable difference other than the green light turning on
3/ Price

Other Thoughts: You can't really measure to see whether or not it's working. I'm sure something in the air is getting trapped in the filter. More than anything I think it is a placebo that makes us feel better. Wouldn't recommend it.
