The 4 inch RAM carbon filter from Rapid Air Movement is one of the best value charcoal filters available today. Measuring 100mm x 200mm, the high quality 5inch RAM filter runs at 170 m3/hr. 

The RAM Pro Active Carbon Filter Range is a professional range of filters designed with the modern horticulturalist in mind. Guaranteed to eliminate odours from small to medium sized grows – our RAM carbon filters use virgin Australian RC412 Carbon. This is considered to be one of the superior carbons for air filtration and has a low ash content (less than 13%) making it more effective than other brands.

The RAM Pro Active Carbon Filters feature a very high specification carbon pore size of 0.02 micron, making it far more absorbent of organic odours.

These superb filters will remain effective for up to 2 years - though exact durability will depend on humidity & temperature levels & using the modern design ( see left) will not only absorb and neutralise grow-room odours more effectively, but are designed not to allow them to leave back out into the environment.

These great carbon filters from Rapid Air Movement also include an elasticated white pre-filter sleeve, which helps catch any larger dirt particles - leaving your trusty RAM filter to clean the microscopic odour particles from your growroom.

The pre-filter can even be washed to help your carbon filter remain highly effective, for longer.
