Been using every night for years now. The noise is pleasant and consistent like white noise machine. Easy to clean when needed. it is not what i hoped for DOES A GREAT JOB!! Uses a lot of energy. Will increase your electricity bill and not much difference in air quality. Works great, definitely helps with my allergies and air quality. I have it on 24/7 and move it to different rooms room time to time.

I would buy another. I returned this because it started making rather loud fan noise after a couple weeks. VERY QUIET I bought two different Honeywells at the same time. I believe the other works better but it is a little loud.3mtm filtrete ultra clean large room air purifier - fap03 Had this unit running for a long, long time now 24/7 and very pleased with it. fellowes ap-300ph air purifier silver/whiteVery quiet considering the air flow going thru it.heaven fresh naturopure hf 380 air purifier review Bought mine in July of 2008, it's now December 2015 and it still works great.

NoDraft technology prevents a cool exhaust draft, and the True HEPA filter cleans the air in medium rooms, perfect for a bedroom, living room, or playroom.

It also helps reduce airborne viruses and bacteria. The carbon pre-filter captures larger airborne particles and helps remove nuisance level odors and smoke. SilentComfort advanced airflow design provides ultra quiet operation.The HEPA filter is easy to clean - simply vacuum on average twice a year (depending on use), and replace the carbon pre-filter every 3 months.

So far I love this product. The test will be when my husband cranks up the fireplace. I had two problems in my small apt. One, I had a lot of dust and two, my neighbors smoke & I had cigarette smoke seeping into my apt all the time! I've had my Air Purifier running for only 2 1/2 weeks and I can tell a huge, huge difference in the dust and more importantly I don't smell cigarette smoke in my apt. any more. I could tell a difference within 24 hours.It's also very portable so I move it into my bedroom at night when I'm sleeping.

I'm so glad I bought it I wish I would have known about it sooner. No review title given I'm very happy with this purchase and I can clearly see the result. Definitely recommend it to anyone who is allergic to dust mites or other allergens. The machine is very big and very NOISY, not a good thing when your trying to sleep. It need to be 3feet from all walls, so putting it a corner is not a option. Air quality is just OK....carbon filter is easy to put on and replace. I sent it back for a full refund. It really works well. I like the light weight of it, and on the medium and low settings, you can barely hear it. We got it because our daughter and kids had to move in with us and the youngest has asthma and allergies. I like the light weight because I move it between his bedroom and the living room. What I don't like is that although is says "no draft" technology, there is still some cool air coming from it, and I can feel a draft. Must be greatly diminished though from other air purifiers, I suppose.

Honeywell 18155 Air PurifierIn the Honeywell line of air purifiers, the 18155 SilentComfort air purifier is a mid range model that delivers decent results for smaller areas, at a reasonable price. This model offers the same lifetime HEPA filter as its counterparts and with the additional SilentComfort technology to reduce noise levels.What I like about the Honeywell 18155 Air PurifierThe lifetime HEPA filter helps to reduce maintenance costs throughout the life of the air purifier.The Intelli-Check feature lets users know when to replace the pre-filter as well as when to vacuum the HEPA filter. Honeywells five year warranty is excellent for a model in this price range.The unit is light, compact and can fit in with the decor of most rooms.What I did not like about the Honeywell 18155 HEPA Air PurifierThe 18155 has a slightly lower CADR rating than most of the other Honeywell units we offer, though it is rated similar to the portable units in the 17000 series.As with the other units in this line, the pre-filter needs to be replaced every three months.
