Aspria OEM permanent HEPA filter replacement for CPU8436HQ model power unit.
HEPA filter is a self cleaning center weighted cloth filter treated with Teflon fluoropolymer to reduce dust retention on the surface for easy self shedding action. Permanent filters are designed to last the life of the vacuum power unit and should only be replaced if damaged by mechanical action (ripped or torn) or damaged by collection of contaminated debris including water or large volumes of drywall dust or fireplace ashes.
No regular maintenance is required, if desired the permanent filter can be brushed off from the outside of the filter or gently blown out with compressed air from the inside if removed from the vacuum.
Measures approximately 14" diameter (about 45" circumference) and 10" deep. Sewn in 3/4" wide metal retainer band & center weight. Fits many other models and brands of central vacuum including some models of Hoover, Canavac, Kenmore and others. Sold 1 each.
