Review on Greentech Environmental pureAir 500: The Ultimate Portable Air Purifier and Cleaner for Home, Office, and Bedroom, Ideal for Up to 850 Sq. Ft., Eliminates Stubborn Odors with Ease! by Jody Grimmett

My wife and I use this air purifier in the large master bedroom with attached bathroom. It does a great job of removing orders from the air and fills the air with a fresh scent. We're amazed at how well it performs given its small size. Noises are not even perceptible. The price was reasonable. We are so pleased with this product that we are considering purchasing the Air Pure Whole Home Purifier.
