Take full control of the smells in your grow space with the Prima Klima Ø100mm activated carbon filter. Paired with a same-diameter extractor fan, it scrubs up to 180 m³/h of air and returns a perfectly neutral atmosphere, both inside and outside your grow room.

A trusted reference among growers, Prima Klima relies on high-density RC412 activated carbon, renowned for its exceptional adsorption power. Hand-picked by BloomLED, an indoor-growing expert for more than 10 years, this Ø100mm filter combines efficiency, longevity and effortless installation for small and medium grow tents.
| Specification | Detail |
|---|---|
| Flange diameter | Ø100 mm (4") |
| Max airflow | 180 m³/h |
| Carbon type | High-density RC412 activated carbon |
| Body length | ≈ 18 cm, compact format |
The RC412 activated carbon traps odor molecules through adsorption. Your grow stays discreet, with no smell noticeable in the room or for the neighbours.
Perfectly sized for a Ø100mm extractor, it filters the air of a small to medium grow tent without choking the extraction flow.
Washable, reusable pre-filter and long-lasting carbon: you extend the life of your filter and cut waste while keeping your budget under control.
Standard Ø100mm flange compatible with all ducting and extractors of the same diameter. Connects in seconds, whether in extraction or intake.
Connect the filter's Ø100mm flange to your extractor fan using a same-diameter ducting and hose clamps. Ideally place the filter high inside the tent, on the intake side, to treat the warmest, most odor-loaded air.
What is the lifespan of this carbon filter?A Prima Klima filter delivers on average 12 to 18 months of efficiency depending on humidity, frequency of use and odor intensity. Keeping humidity under control noticeably extends the life of the activated carbon.
Which extractor should I pair with this Ø100mm filter?Choose a Ø100mm extractor with an airflow close to or slightly above 180 m³/h, such as the Prima Klima Ø100mm 280 m³/h fan, to keep enough negative pressure once the filter is fitted.
The growers' winning combo: a Prima Klima carbon filter + a same-diameter extractor = a completely odor-free, discreet grow room, season after season.
