"I had no idea how much dirty air my bedroom had until I opened my filter 3 months later.. The pre filter catches a lot of the visible dust and pet hair and the H13 HEPA Filter captures the microscopic particles with the Carbon Filter doing it's part as-well...If don't have one of these yet you need one ASAP!! The proof is in my photo. It's a fantastic unit with tons of feature plus easy to use and clean. I love mine!!"

"A must have!! We set up this Air Purifier in our garaged as I do a lot of wood work and other projects...We did a lot of research because Air Purifiers can be very expensive. We settled on this one because of the HEPA Filters and the area it covers 825 sq. ft (which is a little larger then our garage).
It's been running for over 6 months so we opened the filter and found this!! ..Great customer support and quick shipping is a plus. It was an easy 5 stars from us."
