The scientific approach to cleaner air.

Phresh was established in Austrialia in 2007 by a group of friends with a passion for high-tech hydroponics. They wanted to rock the horticultural industry with scientific analysis.

Phresh conduct independent batch testing on each of their carbon filters. Each unit is de-dusted, and the carbon is hand-picked for its exact particle size. Any carbon granules which are too small, too dusty, or do not pass the company’s stringent air-stream tests are discarded. Each grain must be able to absorb a minimum of 20% butane during testing to be considered suitable. Phresh carbon filters only uses premium.
