Zamnesia’s Carbon Filter Air Purifier 100/300 is a 100 mm diameter, 300 mm length inline carbon canister for grow-tent exhaust systems. A thick bed of Australian activated charcoal adsorbs odours as extraction air passes through, while the perforated aluminium body keeps weight low and resists corrosion. This 100 × 300 mm variant is rated up to 300 m³/h and pairs with a 100 mm inline duct fan, suiting compact tents such as 60 × 60 or 80 × 80 cm. Each unit ships with a cotton pre‑filter sleeve installed, a spare sleeve, and rope ratchets for hanging. A silicone connector is not included and must be sourced separately for an airtight fit.
