Dust Shroom

The Horti-Control Dust Shroom is a PATENT PENDING reusable foam HEPA filter designed to keep dust, dirt, bugs, mold, and bacteria out of indoor gardens and air cooled reflectors. Dust Shroom traps 99.9% of all particles 0.1 micron and higher, with ZERO CFM LOSS (as measured on Can Fan H.O. inline fans)! Compare this with other HEPA filters in our industry which reduce the CFM by around 50% and cost about the same and you'll understand why this is such a great product.
