Question: Does it work for a mid size Room?
Document: Had a smaller size of one of these and have had it for years and is still working. This one bought for larger room and is working great. Nice looking. Would recommend.
The tower works great and can definitly tell the difference in the air after 1 day. The only problem is the noise. Like every other review, you get used to it. I use this size in my master bedroom and I have 1 cat and 1 dog. I change my filter about every two months.
I'm handicapped and can no longer go out of the house to smoke. I tried a smokeless ashtray, but it didn't work very well, so I got this product.
Accordingly, if it is placed in a left facing corner, air that has just been cleaned gets sucked back into the intake. That doesn't work terribly well, so where you want to put it is an issue.
I love this machine. seems to work well. not extremely loud like others i have heard. fits in tight areas. Wasnt too expensive for a HEPA.. and sq footage is good. A+
I bought two of these because my allergies are out of control! I have tried everything. These work quietly and make the air feel fresh and clean. My boyfriend is allergic to our cat and his allergies have just about disappeared. He also does not snore any more! The low setting is almost silent. Medium provides nice background noise.
After a week, there's not a speck of dust in sight. I never expected it to work so well!Another plus is that the pre-filter is washable, so you don't have to purchase two sets of replacement filters. Most of the other purifiers that I researched used incredibly expensive filters. I could have easily just purchased a brand new air purifier for the same price.
Well after about two weeks I pulled the filter out, it did a real good job of pulling out dust, fuzz, hair. washed out the dust and fuzz it did take a little more work to get the hair out,  the other filters looked ok. we ran the filter on two most of the time, it is a little noisey. It did a real good job, I would like to have one more. We have three dogs.
This unit makes an immediate difference in air quality. It seems to be well put together and made out of high quality plastic. However,there are two things that you should know regarding where this unit will work well and where it won't.First, even on low speed the fan makes a high pitched wine. It is okay in an area where there is some background noise, but not a good choice for a bedroom.Second, air does not blow straight out the front.
I should get one for every room.
Answer: Yes, quite well.  I have it in my living/dining room area.
