160R2/AN/DT Alpha-Stat pre-filter replacement 3-pack

Part #: E-1526B (1519)
Description: This filter slips over the outside the filter cartridge; it does not replace the HEPA or filterdown which are located inside the cartridge. The Alpha-Stat uses mechanical filtration and an electrostatic charge to increase the capture and retention of submicron particles including dust, bacteria, mold spores, abestos and smoke, and will help your unit absorb odors better by keeping dust off the granular carbon in the cartridge. Rated MERV12; 86.8% efficient at 1.0 microns. Should be changed every month or two to keep your unit working at peak performance. Sold in package of three.
