What our customer's say!

"Works great 4.5 stars", 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!", 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 I got this version to replace an older, outdated version I had when I needed a new filter and couldn't find out because it had been discontinued.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?", 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", 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!", 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.

Read this reviews before You buy...

"Loud on High", It seems to work well, but is too loud when set on high. I think the name of the unit is misleading. It also takes up a lot of room.

"Great Air Purifier", I love this air purifier. I bought this because it had a permanent filter. I'm not so sure the filter traps as much particles as a conventional paper filter. This air purifier uses a filter that is similar to a high performance car filter like K & N performance car air filter. It is basically a lifetime filter with an oil coating on it. It allows more air to pass through and relies on the oil coating on the filter to help trap particles. I know for a fact that the high performance car air filters do not trap as many foreign particles as the stock paper air filters, so this leads me to believe that the same would be true in home air purifiers.

I didn't realize this until after I purchased this product but I'm still happy with it. I didn't want to spend the time or money constantly buying new filters for this air purifier.

On the low setting it is very quiet but the unit's fan draws in very little air and as a result purifies little air. My pre-filter had no dust on it at all after I left the unit on this setting continuously for a few days.

The unit is most effective on the high setting, there was a lot of dust on the pre-filter after only half a day. I just use a lint brush every 1-2 days to clean the pre-filter. You should know that the unit is very loud on the high setting and should only be used on this setting when you're not home. It's impossible to sleep with the unit on high.

I'd advise you to use the medium setting when you're at home. The unit is even quiet enough on this setting to sleep.


"Quietly controls odors and allergens.", Two cats and two smokers produce odors which are pretty awful. When combined, they become a force to be reckoned with.

After trying the ionizer route and finding they make the air sort of perky but still full of odors, I went with a HEPA filter that used a carbon pre-filter to help control both allergens and odors. The Silent Comfort works, but the label is a bit misleading as the unit isn't silent nor a recliner. Anyhow, the breakdown:

+ When the cats do their business, I don't know even if the unit is on low.
+ Air circulation improved which in turn reduced heating/cooling efforts.
+ Cigarette smoke visibly gets sucked into the unit, odor is gone within an hour on all settings.
+ Very easy to setup out of the box though Honeywell could splurge a bit on a maintenance guide.
+ Extremely quiet, though still audible, on low.
+ Quite and audible on medium.

- I suspect that the machine is going to nag me to clean the filters despite the claim for "normal" use which no doubt expects laboratory style clean-rooms are a good template.
- On high the unit is loud, not so loud you can't endure it but you can hear it from about 50' away with the door closed.

Conclusion: The negatives aren't a big deal, nor the slightly mischaracterized notion of "silent" and "comfort", so it's an easy 5/5.

"Nice Air Purifier", I bought the Honeywell 18155 SilentComfort. It truly is quite on low but it's big. I managed to fit that in the tiny baby's room. It works great. I can hardly hear it in the baby monitor. I do recommend this one if you can spare the room. Larger fans are naturally more quit anyway. I'm actually logged in to buy another one for my living room.

"Quiet, almost too quiet", I never appreciated this product as much as I did until I just went to change the pre-filter. After 6 months of almost constant use it had a thick buildup of dust all around it.

After purchasing this product I did notice the air in my apartment just seemed fresher, it did not seem as stuffy and cooking odors did not linger as long.

When I first purchased this Honeywell I turned it on the low setting and could barely hear it, which worried me because part of the reason I bought it was for white noise at night. On the high setting it is loud enough to provide enough white noise.

In the six months of owning it has been very dependable and easy to use. I highly recommend it.
