Build-Your-Own Filter Cartridges for Water
Unscrew the bottom of these cartridges and fill with your own media. Cartridges fit standard filter housings. They can be cleaned for repeated use.
Acid-washed filter media reduces ash content and dust particles.
Plastic Filter Housings with Cartridge for Reducing Odor and Chlorine in Water
These filter housings come with a cartridge that filters odor and chlorine from your water line. They have a pressure-relief valve that allows you to release pressure prior to replacing the cartridge.
Opaque filter housings are light-blocking to minimize algae growth.
Clear filter housings let you monitor debris collecting in the cartridge without stopping flow.
Filter housings with flow-control valve allow you to stop the flow to replace the cartridge.
Filter housings with compression tube fitting adapters let you connect to tubing (sold separately) so you can route flow around a clogged cartridge.

Plastic Filter Housings with Cartridge for Drinking Water
Prepare water for use in beverages, food preparation, and ice production. These filter housings come with a cartridge that prevents scale formation, which can damage equipment. They also come with adapters and a length of tubing for under-sink installation between a water line and faucet. Both the filter and the cartridge meet NSF/ANSI 42 and 53 for use with drinking (potable) water.
Filter housings with a flow-control valve let you stop the flow to replace the cartridge.
Filter housings with a maximum flow rate of 3 gpm hold two cartridges for additional flow. They require two replacement cartridges.

Faucet-Mount Plastic Filter Housings with Cartridge for Drinking Water
Tap into great-tasting water by screwing this filter directly onto your faucet. It comes with a cartridge that filters out sediment, chlorine, and other particles that cause unpleasant tastes and odors. The cartridge lasts approximately two months or 200 gallons of water. Filter housing is opaque white so it blocks light to minimize algae growth. It is not recommended for hot water.

Odor-Absorbing High-Vacuum Oil-Mist-Eliminating Exhaust Filters
To keep airborne oil and odor out of your work environment, connect these filters to your high-vacuum oil pump. They purify pump exhaust in two stages: a fiberglass layer captures oil and collects it into a drain, and an active carbon layer removes any odor-causing oil or chemical vapors. Attach the quick-clamp fitting on the filter inlet to your high-vacuum pump. Use a ring and clamp (sold separately) to complete the connection.
