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!

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 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.

Really happy with it

Love them

Not worth the cost

works as advertised. cleans the air nicely. I might buy more

Easy set up, and they run very quiet! Great features like a timer and multiple speeds.

Easy to operate.... quiet...
