Does it filter air in an entire house (mine is less than 900sq ft)? Or does one need to be placed in each room?

It's a great product I use it in a 500sqft room and it works well. If you have multiple rooms I think you would need additional units.

The best way to use it for your area would be to alternate rooms every other day. The specs state 625 sq. ft. on high but I alternate areas on setting four and it more than does the job. It pulls a lot of dust and debris from the air, so check the filters to wipe down clean at least every month! I've had mine about 3 months and my daily headaches stopped immediately. I've had NONE! i run it 24/7 and always put it in my bedroom overnight.

Hi KatieeB, I pulls air from the back and through the filter, so it needs to sit out a 12"-18" for walls and furniture. It then blows out the air from the front. I have cats and I love this air cleaner, although I have only had it about 3-4 months. I always run it on the 2nd setting, not terribly loud, but it can easily be heard. If you run it on the lowest setting it is almost silent. I hope this helps, Shirley.

It's a great unit for a bedroom, probably would work fine for 250 sq. ft. I bought it for my daughter who has asthma and it made an amazing difference for her. You can put it on automatic and it only works when it needs to. I think it's a great little unit. Only for dust it work very well, but if you need it to, it does so much more.

I leave it on low 24/7 in the cats room. It keeps the air fresh. Once a week I turn if off for a few hours. I have been using it continuously for about 3 months. I bought several after the first one worked so well. So now I don't have to move it from room to room.

It is a HEPA type filter, which is about as close to one as you'll get in a unit this size. I use it in my computer room and it filters allergens well for me. I have horrible allergies. Make sure you are using it in a small area (10x10 or so) for best results.

I use it in my family/sewing room - lower level, no windows. I run it all the time mostly on low . Very quiet. Have had to clean it twice. Hepa filters replacement is expensive but I haven't needed to do that. Have had it 2-3 yrs.

i can tell you that this compact air purifer works well for a smaller room which if you are looking for about 100 ft it would be good to have and its efficient and quiet.

I don't keep a fan next to it. I have a ceiling fan I keep on low and an air purifier that runs, so there is air movement in my home. Seems that is all the air I need, it works great that way.

This is an air purifier for a 250 sq, ft. room. It is not a carbon filter. This is perfect for people with allergies etc.

The unit is nothing more than a squirrel cage fan like the one on your furnace. It draws the air through a filter and it can be mounted where ever it will draw the air for your application. The height recommendation is a safety thing so you don't hit it if you move under it--unless you are very tall!I like mine a lot.

The product description, here http://www.filtersfast.com/P-Honeywell-HHT-080-HEPAClean-Tower-Air-Purifier.asp?gclid=CNzQ2-WG8rsCFeZ7QgodmHoAzg says up to 169 sq ft. My rooms are around 150 sq ft and it works nicely for that space.

Yes, it is such a nice little guy it will work quietly anywhere in the room. But i am sure for the best result you want it to be able to suck in the air you want to filter.

I actually use a different filter that i place on top of the screen. I understand that there is no way to attack the filter that is why i just place over the filter. This type of filter (Filtrete) I cut and actually cover the window where the air blows. I am deployed and the the dust enters the AC. In order to privet dust from entering the room, I have to tape the filtrete over the the window that blows the cld air inside the room. I change the filtrate every two weeks and that's how fast the filtrate accumulates the dust and pollen. It does help though, I have weak lungs, and so far it does help clean and trap those dust particles in the air. The color white turns gray over a span of two weeks. It doesn't look very neat but i use it for the purpose of really filtering the air in my room.

The filter is a hepa filter that goes in the air return of a central air unit. I believe it could go in the ceiling vent or as in our case an air return in the main halway.

It comes with a HEPA filter and a charcoal pre-filter. I would suggest buying a pack of replacement charcoal pre-filters at the time of purchase because they get used up every three months or so. I think that they reccommend it for use in rooms that are 168 square feet (12 by 14 feet). I use it in a larger room, and I think that it does accomplish something (I see less floaties, smell less kitchen odors), but its not as effective as the unit I run in my bedroom, which is a smaller area. If you have serious allergies and this is the solution I would buy a unit that is suggested to run in the size room that you have. If you're a mild allergy sufferer, then it may do well enough for you in a larger room.

Mine is mounted on the ceiling with a conventional air filter taped to the front and the back. Standing below about 2 feet in front of it I measure 59 dB on low, 60 on Medium and 62 dB on high. I generally leave it on low, not so much because of the marginally lower noise but because it makes a rumbling vibration at higher speeds and low accomplishes the desired results.M

I am using it in my bedroom which is about 17 x 17 and it does a good job. I run it during the day for about 10-12 hours. It has really helped my breathing at night during allergy season. Haven't had any problems. I only run the ozone purifier feature occasionally to eliminate odors. I leave the other air cleaning features on.
