The Phat family offers premium products for air ventilation and filtration along with fan noise/air noise suppression.
Phat filters use proven odor-killing technology. They are packed full of high-adsorption-yield, high-density virgin carbon—the very best carbon on the market. The quantity of the carbon plays a role just as the quality does, and the carbon bed in Phat Filters is a true (not rounded up) 2 inches thick, providing more carbon for extended filter life.
