Filter Media Products

We do what others can’t. Good, clean water without hazardous ingredients.

Pathex and PathShield filter media offer a new approach to water treatment by killing bacteria when it comes into contact with filter media granules. No chemicals are used in the process, and no harmful byproducts are released.

The filter media is available as a drop-in replacement for untreated sand media in most sand and multi-media water filters. It is stable, non-toxic, not consumed, non-corrosive, requires no power source to kill bacteria, and is not affected by temperature changes.

The result? Good, clean water for industrial, stormwater and health care settings.
