Works great 4.5 stars 
2008-09-07
We've had this unit plugged in for just under a month and the difference in my girlfriend's cat allergies is amazing. We crank it up to medium or high when we come home for the evening, but leave it on low overnight and while we're at work. The only draw back is that it's quite large. Luckily it works well even without the recommended 360 degree clearance. It doesn't do much for odors, but that's not what we wanted it for. All-in-all, a great buy.
Excellent and as quiet as advertised! 2008-08-19
I have a small room with a dog, a rat in a cage, and three ferrets, so we definitely need an air purifier to "purify" the air in here! I got this version to replace an older, outdated version I had when I needed a new filter and couldn't find out because it had been discontinued. I have to say, it does look nicer and it is quieter, but I found that the older version kept the pet smell out of my room more. Still, I am very happy with this product! When it is set to low, you can hardly hear it at all!
Why does this air purifier smell like wet dog? 
2008-07-31
I got this because of the overwhelming positive feedback it inspired. Shipping time was light-speed fast and the unit worked mostly ok but, like other reviewers, I HATE the instruction booklet.
OK, the unit comes already put together but you need to put the pre-filter in before you start the unit up. This is actually a very easy thing to do but it becomes very confusing very fast when you try to follow the crappy instructions in the booklet. You don't need to take the top off (contrary to instructions). You actually need to put the black velcro-looking strip along the inside of the bottom of the unit, (This will become clear once you are looking at the thing.)
The other problem is that after a couple of weeks, we all started noticing a 'wet-dog' smell in the air. Not horribly offensive, but not aromatic either. We had just had the house professionally cleaned so I knew that all potential stinkies had been taken care of. On a sniff 'n' search, I discovered that the Honeywell was the culprit - stinking up my clean house! I took the thing apart, looking for the problem. Found nothing, it was completely clean. The filter itself did not smell but the air being expelled was awful. I found that if I turned it down to the lowest setting, it went away (or became unnoticeable) but after a couple of hours of medium or high, the phantom smell returns.
Any ideas??
Other than that, this is a pretty good unit and not loud at all. On high you notice it more but my kids successfully cover it with yelling, screaming, laughing, arguing etc.
As for cleaning the air, I do notice cooking smells leave the downstairs area faster and our asthmatic sleeps easier at night. So I still recommend it but if I were to buy another one, I might try a different model.
Smoke Buster 
2008-07-31
Large local forest fires prompted this purchase. It has been a life saver. Running 24/7 with the air conditioner in the house has kept the living room area free of all smoke smell. Even my 84 year old mother did not have to leave. We ran it on medium speed most of the time and could hardly hear it.
Not too shabby! 2008-07-09
I like this air purifier, although I've never bought one before. Shipping was pretty slow, and the delivery guy didn't even knock, he just left it in the rain, but it didn't seem much worse for the wear. I've had it for about a month now, and I keep it on 24/7, usually on high (I can't hear it over my AC, anyway), but I've tried all 3 settings. Here's what I think:
Pros:
Yes, it is QUIET, the high setting is maybe 40-50dB, like the humming of an old fridge.
It works great on SMOKE and SMELLS - I smoke "herbal" cigarettes in my 300sqft apartment and they smell a lot! Not only does this suck the smoke out of the air (pretty cool!), but it really helps with the smell that usually lingers for hours after smoking.
It works on PET DANDER - yah! my apartment no longer smells like an 80 lb greyhound who rolled in god-knows-what!
Cons:
DUST? One of the other reviewers said that this helped reduce the amount of dust in their apartment, and I was so excited, because my apartment gets ridiculously dusty every 3 days or so. So I set up the purifier, let it run for a day, then I dusted, and waited. No dice, I had serious dust again in like 3.5 days, too bad :(
Although you just vacuum the HEPA filter, YOU STILL HAVE TO BUY A REPLACEMENT PRE-FILTER.
Really reduces Pet Allergies!!! 2008-07-09
The SilentComfort True HEPA air purifier removes at least 99.97% of common household particles as small as 0.3 microns from the air passing through it such as dust, pollen, mold spores, tobacco smoke and cat dander. Comes with bonus pre-filter
Great choice of a permante filter for Mexico City 2008-07-06
The power consumption is not too bad.. I measured it this morning and its like 90W / 55W / 45 W
The lowest mode is really silent and works like white noise which is great.
I didnt believe much that the air would feel fresher but it does... in a couple of hours all seems much colder and breathable
Love the fact that the HEPA filter is permant
Price is more than great for its characteristics
Size is huge...really, take that into consideration because its not very discreet in the room
Only thing that is ridiculous is that Honeywell insists the filter should operate 24h .... this might be a good idea for your room but not for the environment, especially if you are not in your house for hours during the day.
Highly recommendable
Reliable and effective!!! 2008-06-28
Our second Honeywell air purifier in three years.....so far so good. No matter the sound level, even at the lowers setting, your brain accomodates and it's not a bother anymore. Prefilter does freshen the air due to the carbon embedded within. Will probably buy another in a year or two of if a great sale comes along!
Quieter than others... 2008-06-26
I have allergies/asthma and own both the Honeywell 18155 (in living room) and the 17000N (in home office). The Honeywell 18155 is MUCH quieter. It's even quieter on "high" than the smaller 1700N is on "low" -- both work very well.
Good Air filter 2008-06-16
I must warn that this guy is bigger that it looks in the picture, so I would check the size specs. However, it is quiet on the low and medium speeds and really, in my opinion, is not to loud on high. I am happy with this purchase.
