The CAN-LITE 3500 Filter Sleeve is a replacement pre-filter designed to protect activated carbon filters in indoor cultivation. It retains dust and pollen, facilitates maintenance, and helps maintain a stable 3500 m³/h flow rate in rooms and grow tents where discretion is essential.

The CAN-LITE 3500 Filter Sleeve works as the first mechanical barrier in extraction systems with activated carbon. The technical multilayer fabric captures suspended particles before they reach the carbon bed, preventing premature clogging and performance drops.
The perimeter fit around the filter cylinder reduces side leaks and keeps pressure loss low, so the extractor operates in a comfortable range with less noise and greater efficiency. This replacement extends the life of the main filter and, by keeping the circuit clean, reduces deposits in ducts and turbines.
Recommended washing every 3–4 months with warm water and neutral soap restores the textile's capture capacity; in environments with frequent pruning or substrate movement, intervals should be shortened.
Moisture management makes the difference: above 82% RH activated carbon reduces effectiveness because the aqueous film in porous cavities limits contact with volatile organic compounds.
Keeping the CAN-LITE 3500 Filter Sleeve in good condition, along with proper humidity and temperature control, reinforces odor neutralization and stabilizes the nominal flow rate 3500 m³/h.
Installation is quick, without special tools, using elastic bands or clamps to ensure a tight seal at both ends.
Ideal for professional projects and also for setups with cheap indoor grow tents, where every euro invested in maintenance directly impacts efficiency.
Among cannabis growing accessories, this pre-filter offers a very favorable cost/performance ratio and fits perfectly with discreet ventilation strategies in a Grow Shop in Spain.
In indoor growing facilities, odor control depends on the balance between filtration + recirculation. The CAN-LITE 3500 Filter Sleeve keeps the activated carbon clean for longer, stabilizes airflow, and helps calibrate extractors, silencers, and ducts to achieve effective and discreet microclimates.
It is used to protect the carbon filter against dust, lint, and pollen; prevent blockages that reduce flow; extend the useful life of the set and maintain performance around 3500 m³/h. As an additional effect, it reduces accumulated dirt in fans and tubes, improving hygiene and energy efficiency.
Considered an essential maintenance part among indoor growing accessories, the CAN-LITE 3500 Filter Sleeve allows the filter to work at the sweet spot of the curve, with less pressure loss and better response to odor peaks. It fits in production rooms and in cheap indoor grow tents, enhancing the odor control strategy without complex investments.
Recommended use from system start-up and whenever signs of saturation appear: increased external odor, noticeable drop in flow, darkened fabric, or increased extractor noise due to overexertion. After pruning, transplants, or work that raises dust, a visual inspection and cleaning or replacement of the pre-filter is advisable if necessary.
Turn off extraction and disconnect power. Remove the previous cover by sliding it out. Place the CAN-LITE 3500 Filter Sleeve from the blind end of the filter until the cylinder is completely covered. Adjust both ends with bands or clamps to prevent peripheral leaks. For washing, use warm water and neutral soap; rinse well and let dry completely before reinstalling. Keep operating humidity below 82% to preserve the effectiveness of the activated carbon.
