Scrub the Skunk Funk from your space with Maverick Sun"s 100% Virgin Carbon 4" Filter rated at 200 CFM. The Skunk Filter utilizes the highest quality virgin carbon available on the market includes a flange and pre-filter. Most competitors use carbon pellets inside their filters. Using this medium, only the outside of the solid carbon pellet is being utilized for activated carbon intake. The Skunk Filter utilizes granular carbon with thousands of micro PORES throughout each piece, so you"re not only getting all the external activated carbon, but takes advantage of all the active carbon contained within the piece as well. More active carbon surface area equals better filtration. Maverick Sun"s Skunk Filters use a full 2" bed of 100% Australian Virgin Granular Carbon to ensure maximum filtration and odor removal. We use aluminum base ends for reduced weight for ease of handling. Paired with a Maverick Sun Wind God 8" fan you will have one of the most effective odor removal systems on the market.
