3M Filtrete Electrostatic Furnace Filters
Rather than just trapping dust, pollen, and other airborne allergens as they pass through, these pleated furnace filters actively attract nasty particles into their clutches thanks to their electrostatic charge. The filters come in a wide range of sizes to fit most household furnaces and are protected by a moisture-resistant cardboard frame.
- Electrostatically charged filter
- Pleated design increases dust-trapping surface area
- Moisture-resistant cardboard frame
- Each filter lasts up to 90 days, so up to three years of protection for 12-pack
