Prima Klima K2602 Carbon Filter 475m3

The K2602 sits a notch above the K2601. Optimal flow is 475m3 per hour and it tops out at 620m3 per hour. That extra headroom suits a busy single-light tent, or a small corner running two lights. It keeps the 125mm flange, so GT125 fans and standard ducting bolt straight on.

More carbon sits in the bed here, giving the air longer contact on its way through. That matters once humidity climbs and the smells turn stubborn. The body runs to 400mm tall and tips the scales at 4.5kg. Reach for it when a dense tomato or chilli canopy starts to outpace the K2601. Hang it in the tent, duct the fan onto the open flange.
