Prima Klima K2603 Carbon Filter 800m3

The K2603 holds enough carbon to clean a two-light grow room. Run it around 800m3 per hour for best results; it will pull 1150m3 per hour flat out. The 160mm flange pairs it with the GT160 fan, which is the obvious partner at this size.

This is a room filter, not a tent accessory. It stands 650mm tall and weighs 7.8kg. All that height packs in more carbon, so refills come round less often even with a busy canopy. Growers with a wall of tomatoes, or a propagation bench that fills the room with green, fit one to keep the air clean. Mount it on the extraction line and feed the fan from the open end.
