I was provided an opportunity to try this air purifier in exchange for leaving an honest customer review.  I'm truly impressed with the overall quality, design, durability, and functionality of this air purifier. It has a sleek and modern cylinder look, is lightweight and easy to transport around the house.   Set up is also very quick and painless.  This air purifier is so quiet and easy to use. I was amazed by the ability of this purifier to detect dirty air. As a part of a test, I blew out a candle and within seconds the air purifier detected the change in air quality. I was in awe of how quickly this purifier eliminated the contaminated air and improved the air quality. I highly recommend this product because it works well and it will not disappoint.
