Honeywell HHT-080 HEPAClean Tower Air Purifier with Permanent Filter Honeywell HHT-080 HEPAClean Tower Air Purifier with Permanent Filter

Pros: Can vacuum the filters, three speed settings

Cons: I got this specifically because there's a smoker in the house. I wish I'd read the first review here before buying it. He only smokes in his bedroom so obviously it's in there, but I haven't noticed much of a difference even though it stays on high speed.

Other Thoughts: It may work fine for clearing dusty rooms, but I really don't know. The high speed is a tad loud, but he actually likes the background noise.

Pros: Very effective. Turned it on as soon as I got it, and it cleaned up the air in my room within the first 3 hours. I have asthma as well as a recently acquired cat allergy. We live in a dusty old house and we have a lot of cats so I wasn't sure if this was going to be effective, but the very first night I used it, I could tell that I had not wasted my money. The air smells very clean now, and the best part is I can breathe at night!

Cons: None so far.

Other Thoughts: Some reviewers commented about noise. It is a little obnoxious on high, but it's not really that bad. I find medium is a completely tolerable noise level, and low is whisper quiet.
Also, the manual says you are supposed to replace the filter every 6 months (unlike what the website says) but I haven't owned it long enough to know if that's actually necessary.

Pros: Powerful, PERMANENT filtration, and very effective!

Cons: The fans are a hair noisier than I had expected on levels 2 and 3. At low, they are whisper quiet however. Not worth knocking an egg off in my opinion.

Other Thoughts: Living in Arizona, the air conditioning is on a good portion of the year, and as such dust can be a pretty big problem. As our family has grown by 1, we felt we needed to do something about the ever-growing air quality problem in our home. (HVAC filters aren't cutting it)

This has been a really good solution, and the air is noticeably cleaner/easier to breathe. We wake up with less stuffy/runny noses, and my computer isn't gathering nearly as much dust after putting two of these in high-traffic areas. I can recommend these for those with young children or dusty homes without hesitation. :)

Pros: put it down stairs next to the cat box! it has greatly helped with the smell

Cons: none

Other Thoughts: since i dont really know much about the air purifier's i cant really say much, but it does push a good amount of air, about the same as a cheap box fan.

Pros: Nice unit, no smokers in my house but I have it set up in my home office where I do computer repairs. Room smells much cleaner. Dust from other peoples computers made this room the dustiest of the house, filling the vents in my PC's in a day or 2... Let it run for a few days, then cleaned my computers and 3 days later, no build up.

Cons: none noted

Other Thoughts: loud on high, very quiet on low. I put it on low when I am home and turn it up when I am out...thinking about getting a couple more for the rest of the house.

Pros: Good form factor, low price.

Cons: HEPAClean is not the same thing as HEPA. "HEPA-Type" means it gets close to what a HEPA filter would do, but doesn't quite reach the mark. Newegg should not show the filter as "HEPA" in its specifications.

Pros: fairly cheap price wise and best part is no filter replacement !

Cons: fan on high is kinda loud..

Other Thoughts: fan on low is perfect to sleep by if you like a little background noise..

Pros: I live in an apartment with three cats and two ferrets. It does a pretty good job of keeping the odors down. The noise level on low speed is hardly noticeable. Permanent filter that vacuums clean.

Cons: It has three speed settings. At low speed the noise is hardly noticeable, about the same noise level as a desktop PC. On Medium speed there is a lot more noise, comparable to a plugin fan. High speed is just obnoxious.
It's ugly. You'll have to hide it before guests come over.

Other Thoughts: Not having to buy filters is nice, you simply vacuum the filter to clean it.
Perhaps I'm a design snob, but these air purifiers would not fit alongside anyones interior fixtures. It basically looks like an oversized air conditioning vent from some modern car. If it resembled a home theater speaker, (a black box) it would be more aesthetically pleasing.

Pros: Kicks a lot of air. nice filter design.

Cons: does not help much with smokers, but it keeps the dust and other oders down pretty well. and can be a little loud if it's close to where you work and on high.

Other Thoughts: Over all I am pleased with the two we bought. The price was right!
