It works very well and very quiet. Now I am worry free about cooking smell after using it. The smell goes away just a few moments after cooking done. Just love it.

Wish we would've bought them sooner, began to notice a difference in the air quality within the first 8 hrs. Definitely helped with our allergies ! Highly recommend.

I bought these air cleaners about a month ago and they seem to be working very well. On high they’re a little noisy. My husband smokes in the house and we have four cats. But it seems like the air smells better, but I may have to give it more time.

I was tired of the dust floating around even with regular changes in the furnace filters. These cut it down. They are great for odors too. Feels cleaner. The air is definitely cleaner.

I am happy with the purchase but it has helped but not as much as I had hoped with the allergies but I do have 2 dogs and 1 cat so whatever help I can get is good. My dogs also have allergies this season as it is an unusually bad allergy season.

Purchased these on line at Sams Club with free shipping. Arrived fast...one is in my main bedroom and the other in the room with the cats litter box. So far it is doing a great job of keeping the dust down from the litter box. With winter and running the heating and not being able to open up the house to get fresh air inside I wanted to keep the house smelling fresh and capture airborne particles. If you look at the specs on these units they have a great rating. Now just need to see how long the filters last..

I was skeptical when I first bought these but within a week they reduced visible dust in my office and living room so tremendously that both my wife's and my allergies are no longer an issue. They are improving our quality of life and our desktop computers' life spans. We couldn't be happier.

Purchased a set of two of the 'Germ Guardian - Digital 3-in-1 Air Cleaning System UV-C' for a residence with elderly people with incontinence problems. Thru the winter months the air was stale and thick with urine smells. After only a week of running these for 24/7 there was a noticeable difference and with continued use it is again bearable to enter the home. With spring coming up we can again open the windows for some fresh air but we did go ahead and purchase two more of these and plan on using them when windows are closed. A true life saver!

I purchased two of these air filters and I am now planning to purchase two more. With two cats, both with very fine fur, I constantly had fur under furniture and moving on the floor. Since adding these filters, I've had no fur under the kitchen table where it was most noticeable. My five computers, I invest, doesn't gather the dust they always have. I would recommend this product to anyone who has a problem with dust and fur.

I bought this set about a month ago and they work great. They are easy to operate. I was able to tell the difference in the air within a few hours. I use them maybe 4 days a week. Sometimes for several hours and other times just a couple of hours. They are not intended to be a fan but I welcome the cool breeze that blows while it is summertime.
