Eliminate 100% of the odours from your grow space with the Garden HighPro ProActiv Ø150mm carbon filter. Built around high-density coconut activated carbon and an airflow of up to 690 m³/h, this filter is the discreet, long-lasting solution for growing with complete peace of mind. Hand-picked by BloomLED, an indoor growing expert for over 10 years, it pairs with your Ø150 extractor fan to scrub the air continuously, leaving not the faintest trace of smell outside your tent.

The ProActiv's performance comes down to its RC4-12 coconut-shell activated carbon. Denser and more porous than conventional mineral carbons, it offers a far larger adsorption surface: each odour molecule is captured deep within the carbon rather than merely filtered. The result is exceptionally complete neutralisation of volatile organic compounds, even during the most intense flowering periods when odours peak.
The filter body is wrapped in a fabric pre-filter that traps dust and extends the carbon's lifespan. This sleeve is washable: regular maintenance keeps airflow at its rated level and guarantees optimal filtration throughout the cycle. Designed for indoor use, the ProActiv Ø150mm mounts vertically or horizontally and works equally well in extraction or air-recirculation mode inside a grow tent.
With a 150 mm connection diameter, this filter is perfectly sized for medium to large grow spaces. Paired with an extractor fan of equal or slightly higher airflow, it refreshes the air several times per minute, helps regulate temperature and humidity, and ensures a complete absence of odour in the room housing your setup.

Coconut activated carbon captures every odour compound for a completely discreet growing environment, from seedling to harvest.
A large volume of air treated per hour, ideal for medium to large grow tents and powerful Ø150 extractor fans.
More porous than mineral carbons, RC4-12 delivers a greater adsorption surface and a longer service life.
The pre-filter sleeve traps dust, protects the carbon and can be washed to maintain airflow over time.
Compatible with most Ø150 mm extractor fans and ducting, with vertical or horizontal mounting to suit your setup.
Choose a Ø150 extractor fan with airflow equal to or slightly above 690 m³/h. The filter must always be able to absorb the air being drawn through it: an overpowered fan would shorten the air's contact time with the carbon and reduce odour-control efficiency. A model around 600 to 800 m³/h is the ideal match.
How long does the activated carbon last?Under normal indoor-growing conditions, coconut activated carbon retains its efficiency for 18 to 24 months. Actual lifespan depends on humidity (very humid air saturates the carbon faster) and odour intensity. Maintaining the pre-filter regularly and controlling humidity will noticeably extend its life.
Does the filter work in air-recirculation mode?Yes. The ProActiv Ø150mm can be installed in extraction mode (filtered air is expelled outside) or in recirculation mode inside the tent, with the fan simply moving air through the carbon. Recirculation is useful when venting to the outside isn't possible.
Should it run continuously?For optimal odour control, it's recommended to run the fan-and-filter combination continuously, or at least throughout the photoperiod. Permanent ventilation also ensures air renewal, thermal regulation and a steady supply of CO₂ that benefits your plants.
