Pro Grow Filters
The quality of natural carbon sources varies from batch to batch. Pro Grow Intake & Inline carbon filter best for air filtration and ventilation systems setup. Unlike our competitors, Phresh Filter only buy the premium 20% of any carbon produced. Our on site Carbon Analysis Laboratory allows us to independently batch test, dedust and hand pick our carbon. We use the exact particle size required for the best air flow (Pro Grade 4/8). Any carbon that is too small, too dusty or does not meet our stringent air stream tests (minimum 20% butane absorbtion) is sent back to the manufacturer. The result is the smallest, lightest and least restrictive carbon filter canister available. Hydroponic carbon filter water incline. The advantages are easier installation, more airflow, and better air filtration with extended operating life. Great with any Indoor hydroponics system. Some examples of indoor hydroponics systems are Ebb & Flow, Drip Irrigation and Deep Water Culture (DWC).
