HEPA Filters - Air Filtration Products:

The term HEPA stands for “High Efficiency Particulate Air” and is known as the Ultimate Filter. HEPA Air Filters are a High-efficiency particulate air filters that come with a pre-filter to filter out large particulate, a carbon filter to adsorb odors, and a HEPA filter to filter particulate down to 0.3 microns in size. This is absolutely the perfect air filtration filter for any type of HEPA Vacuum or HEPA Vacuum Filters. HEPA Filter is an air purifier filter that works by utilizing spun-hooked glass fiber rolled into a paper-like material. This material is pleated to increase the fiber surface area and bonded, or potted, into a frame. Hot melt is used to hold the pleats far enough apart to allow air to flow between them. HEPA Filters are available in standard sizes along with other sizes that can be custom designed through RP Fedder.

ULPA Filters – Air Filtration Products:

The term ULPA stands for “Ultra-Low Penetration Air.” ULPA Filters are available in standard sizes for work stations along with other sizes can be custom ordered through RP Fedder. Like HEPA filters, ULPA filters are made of spun-hooked glass fiber rolled into a paper-like material. The ULPA Filters have the efficiency specification for environments like Commercial Air Filtration, such as pharmaceutical labs, where the highest degree of clean air must be maintained.
