Customers are impressed with the air quality improvement and quiet operation of this 22" air purifier tower. Many appreciate its ease of use and odor removal capabilities, along with the added benefit of a UV light. However, some customers express concern regarding the filter replacement cost and its coverage area.

    We purchased this air purifier because of all the dust in the dry air of Arizona. We also have long haired cats. So, this Germ Guardian has helped improve the air inside our house to a more comfortable level with no more sneezing. Plus, it makes the air seem fresher. So glad we finally decided to buy this Hepa Air Purifier and recommend it.

    It seems to work pretty well. I bought it because during the spring I can really smell cigarettes from neighbors strongly enough to trigger sinus headaches. It doesn't remove the smell entirely (which honestly may be too much to ask) but I can tell a difference if I go to bed without it. It is perhaps a bit loud, though I appreciate that part. I don't need to use my sound machine at bedtime when I have the purifier running. Overall, I'm very glad I bought this and I'm considering buying a second one.
