Polyester media bonded with a fire retardant binder, tackified and blue tinted on the air exit
side. The fiber orientation and graduated density of this media yields greater depth loading and
adhesive enhances particulate retention. This product is a superior replacement for 1” polyester
and 2” fiberglass media. HP 100 BT also makes an excellent prefilter for use in protecting more
expensive high efficiency filters. The media repels moisture and is suitable for use in
temperatures up to 220 degrees Fahrenheit.
