The powers of carbon and fine mesh netting combine in Sunleaves Duct Defenders to create a strong defense for duct systems against pesky bugs and mold, mildew and unpleasant odors. The simple Velcro tabs attach to fan intake systems to prevent pests from getting in, or affix to the fan exhaust system to keep unpleasant odors from getting out. All carbon filters included with the Duct Defenders are replaceable, and both the replacements and the filters are available in 4", 6", 8", 10" and 12" diameters.
