OdorSok 8\'\' x 20\'\' 850 cfm: J

Attach to your fan just like a short length of ducting. Video assembly instructions are online at http://www.odorsok.com/. Each pack includes: carbon filtration cloth, plastic mesh support structure, metal support straps, one roll of duct tape. Unwrap carbon cloth from the plastic mesh support, unfold the filter and insert the plastic mesh support into the carbon filtration cloth, forming a duct-like tube. Metal support straps snap into preinstalled clips in the plastic mesh support structure. Your filter is now ready to be connected to your fan like ducting. There is a prepared support strap at the top of the filter tube with holes for your support hooks. The recirculating air will be efficiently filtered every time it passes through the tube! Odor problems are in the bag! This multi layered carbon cloth bag sets new standards for carbon filters in every way. Full of innovation and versatility, some of the many benefits include: * Unbelievably light - weighs 6 lbs boxed. * Stores at under 1/12th of its working size. * Easy to assemble and disassemble. * Average lower air loss with centrifugal fans. * Work in humidity - Tumble dry when wet. Suitable up to 99% humidity. * Machine wash when dusty, (no detergent) * Air flow capacity from 100 to 2400 cf/m. * Sizes inc: 4, 6, 8, 10, 12, 14 & 16 inch . * Fits any fan and comes with duct tape. * Substantially cheaper than carbon canisters. So how do they work? Odor-Sok Air Filters are constructed using bundles of microscopic activated carbon filaments and fibres. By controlling fibre width to 20 nm, the kinetics (adsorption rate) of carbon cloth is similar to that of a single exposed carbon particle. Air flows evenly across the carbon and with accelerated kinetics (up to ID-2400) and increased surface area, Odor-Sok Air Filters retain all the properties of deep filter bed canisters. Faster adsorption rates means smaller filter equipment and up to thirty times less carbon in use for the same result over a one year period. That\'s how! BSS \"“ Bag Support System Smart thinking and clever use of materials under pin the Odor Sok\"™s patented Bag Support System or BSS.This allows users to choose the direction of air-flow to suit their individual application. The BSS system supports the bag from the inside and prevents the Odor Sok from collapsing as polluted air is sucked through the bag. The bi-directional air-flow properties that BSS provides means more versatility, the smallest achievable packaging and the easiest assembly possible from a collapsible sub frame and any carbon filter to date.
