Description & Features+

Air Purifier by Guardian Technologies. The GermGuardian 3-in-1 True HEPA Air Purifier is perfect for allergy sufferers. With a True HEPA filter, it captures 99.97% of dust and allergens as small as 0.3 microns in size.

The easy to use controls include UV-C control and 3 speeds, including a low speed that runs ultra-quiet. The simple, stylish design looks great in any home environment.

Rated 5 out of 5 by from THE BEST! I live in California in the hills, so the wind and dust are constantly flying in around my house which started to causing breathing problems. I needed something that would clean my air as well as cool off my room. Well, I bought this machine and immediately when I turned it on my stuffy nose was cleared and the nights were cool. The only thing is it doesn't cool off the room like it first did when I plugged it in, so I'm wondering do I need to clean or change the filter.
