GermGuardian 870 Sq. ft HEPA Pure Filter Tower Air Purifier with UV-C, AC5350W, White

I purchased 2 of the Germ Guardian purifiers. They purify an 870 square foot room once every hour. I have one purifier in my TV room, a 224 square foot room. Therefore, the purifier in that room cleans the air every 16 minutes. These purifiers have a true HEPA filter and carbon pre filter that capture 99.97% of the particles down to .1 micron size in the air. The air purifiers are designed by American engineers and are EXTREMELY durable (not cheaply made or flimsy) and are attractive. In addition, they have a UV-C light you can turn on or off which will kill viruses, bacteria, mold, etc. in the air making the air safer to breathe. I live in a rural area by farms and a CAFO that produce a tremendous amount of dirt, etc. in the air. I dusted prior to setting up the 2 purifiers in an effort to verify if the purifiers cleaned/purified the air by removing the particulate matter in the air. I was astounded by how much they removed from the air in just 1 day. I placed the 2nd purifier in my bedroom to replace a different brand, inefficient, non Energy Star air purifier. The Germ Guardian Energy Star purifier was so quiet even on its highest speed, level 5. It so easy to sleep. Both Germ Guardian air purifiers removed so much particles from the air that I personally found it easier to breathe in both rooms! I have been vacuuming the carbon pre filters in an effort to extend the "life" of the combination filter (HEPA plus carbon pre filter). When I read the one flyer in the Germ Guardian box about Guardian Technologies which said: "The guardian of your family's air quality for a happier, healthier home." I hoped it would be true. I can definitely say it is. The air quality inside my home has definitely improved. It is easier to breathe, I'm not coughing anymore. I feel better, there's hardly any dust settling on my furniture as it is being captured by the Germ Guardian purifiers. This makes me extremely happy. I intend to purchase more of these air purifiers. Best purchase ever!

I have this as soon as I walk inside the front door and all I smell is clean air. You can hear it when on the 5th level but not on the 4th. There is a UV light that you turn on and has a timer for up to 9 hrs. so you can be in bed, set timer and stay in bed. This uses the long filter and a little hard to hide as it a tall one. The air flow is so strong that I actually get cold that is how well it works.

I was gonna return it because my kids got me others for Mother's Day. I decided to keep it because I realize this is much better than the ones. My kids got me.

i have been using the Guardian Air purifiers for over two years now and I am pleased with the quality of air that flows inside my home. The units clean the air of particles of dust, and other dangerous pollutants that get into the house and are transported to the many areas by the A/C unit. I think the incorporation of the UV light into the units is an additional and very important safety feaure.

This third air purifier I've purchased from Guardian Technologies. I gave one to our son who has seasonal allergies and it's helped him a lot. The two we have in our house work great.

Purchased on recommendation of a friend. I have been totally amazed and pleased with the quality and quietness and above cleaning the air in my house.

Fantastic air purifier!!!! Works well.

Simple to operate. Quiet.

seems like they put there smaller motor from the 24" version in this because it don't work like the other two I have plus the air comes out one side my other two comes out both sides

I bought a pair of white 5350. They have a high whine, even on the lowest setting. Needless to say, at night , it's annoying. They do the job of cleaning the air but putting them in the bedroom was a problem. I have 3, 6 year old black ones that don't have that problem and also a 9200 that is very quiet, fyi.
