PureFilter Activated Carbon Filter Ø200 mm - 1125 m³/h

PureFilter Activated Carbon Filter Ø200 mm — 1125 m³/h: total odour control

In a serious indoor grow, smell is the first thing that gives a room away. The PureFilter Ø200 mm activated carbon filter captures the volatile organic compounds released during flowering and returns clean air at the extraction outlet. Rated for a maximum airflow of 1125 m³/h, it serves the largest grow spaces without ever throttling your ventilation.

How activated carbon adsorption works

Activated carbon does not absorb odours, it adsorbs them. Its microporous structure creates an enormous internal exchange surface where odour molecules bind as air passes through. The denser the carbon bed and the longer the contact time, the more complete the filtration. That is exactly the design logic behind the PureFilter Ø200: a carbon bed calibrated for 1125 m³/h, so air moves through the media slowly enough to be genuinely treated rather than simply pushed across it.

Sizing your Ø200 extraction correctly

The baseline rule in indoor growing is to renew the entire volume of your grow room every one to three minutes. Multiply length × width × height of your tent for the volume in m³, then multiply by 30 to 60 depending on how much heat your lighting produces. Since the PureFilter Ø200 accepts up to 1125 m³/h, pair it with a Ø200 mm inline fan whose real-world airflow sits slightly below that figure. You keep a safety margin and, more importantly, an optimal contact time with the carbon.

Installation: filter first, always

The most effective layout suspends the filter inside the tent, strapped at the highest point and connected directly to the fan intake. Warm, odour-laden air is drawn through the carbon before being pushed out through the exhaust ducting. Running the filter on the intake side puts the whole circuit under negative pressure: even the small leaks around zips and cable ports pull air inwards instead of letting smell escape. Use a Ø200 mm duct clamp and check every joint for a proper seal.

Maintenance and carbon bed lifespan

Carbon filter longevity comes down to two things: the humidity of the air being treated and the number of running hours. Overly humid air saturates the carbon early, so keep your relative humidity under control. The fabric pre-filter slides off, rinses under clean water and goes back on once fully dry, which noticeably extends the working life of the cartridge.
