ABSTRACT:
Add-on filters for heated-air blowers and other electric motor-powered appliances. The filters are fabricated from a washable, flexible, reticulated foam which traps even minute solid and liquid particles and is adhesively attached to the blower housing. A template, which also serves as a protective cover for the adhesive, has index lines along which a blank of the filter material can be trimmed to size and configured for a particular blower intake.
