Does the Odor-Sok 4" - 12" work as well as the regular pelleted carbon filters? We get asked that all the time - you would believe it looking at it but it does. The good thing is that when smells begin to break through it can be washed one time in a regular washing machine. How does it work? The Odor-Sok 4" - 12" Air Filters is constructed using bundles of microscopic activated carbon filaments and fibers. By controlling fiber width to 20 nm, the absorption rate of carbon cloth is similar to that of a single exposed carbon particle. Air flows evenly across the carbon and with accelerated absorption and increased surface area, Odor-Sok Air Filters retain all the properties of traditional canister filters. Faster absorption rates means smaller filter equipment and up to thirty times less carbon in use for the same result over a one-year period or more. 190 CFM Extremely cost effective Ultra light and compact / less than 6lbs Stores at a fraction of the assembled size Lightweight, durable construction Easy to assemble - less than 2 minutes easy to dispose - compresses to almost nothing Fits any/all manufacturers fans Less air pressure loss with centrifugal fans
