GENERAL HYDROPONICS CARBON FILTERS
Premium Carbon Air Filter

• Designed for the medical industry, General Hydroponics Carbon Air Filters are the only filters certified by the European Clean Air Act (ECAA).

• These filters – sold in the US only by General Hydroponics – are used in Europe for many demanding commercial applications, as well as in hospitals, as carbon air filters effectively remove 99.5% of airborne pathogens.

• General Hydroponics Carbon Air Filters use the highest quality carbon mined from pre-Cambrian ore (not from burned coco coir).

• The carbon grain size of GH Carbon Air Filters is 3mm, while the leading competitor uses a larger 5mm grain. This smaller carbon grain ensures that General Hydroponics Air Filters have greater surface area contact between the air stream and the carbon bed to clean the air more effectively.

• General Hydroponics Carbon Air Filters contain an expanding foam disk to ensure that the carbon stays tightly packed without air leaks.

• General Hydroponics Carbon Air Filters work with any popular inline fan. Calculate the size of your room and choose a fan that completely exchanges the air in the room eight to ten times per hour. Then choose the appropriate filter with the correct CFM and flange size to match that fan.
