The CAN-LITE 4500 Filter Sleeve is a replacement pre-filter for activated carbon filters in indoor cultivation. It retains dust and pollen, extends the life of the cartridge, and helps maintain a stable 4500 m³/h flow rate in rooms and grow tents where discretion is a priority.

The CAN-LITE 4500 Filter Sleeve acts as the first line of defense in extraction systems with activated carbon. The technical multilayer fabric captures suspended particles (fine dust, lint, pollen) before reaching the carbon bed, preventing early clogging and performance drops.
The perimeter fit around the cylinder minimizes side leaks and keeps pressure loss low, allowing the extractor to operate in a comfortable range, with less noise and lower consumption.
This replacement is optimized for filters with a nominal capacity of 4500 m³/h, maintaining a balance between filtration and airflow for consistent odor neutralization over a longer period.
Maintenance is simple: gentle washing every 3–4 months with warm water and neutral soap restores the textile's capture capacity; in very dusty environments, it may be needed sooner.
Controlling humidity makes the difference: above 82% RH the activated carbon reduces effectiveness, as a water film limits contact with organic compounds.
The sleeve is installed and removed in minutes, without special tools, and can be secured with rubber bands or clamps for a tight seal at both ends.
In professional installations and in cheap indoor grow tents, a clean pre-filter maintains airflow, reduces extractor strain, extends the life of turbines and ducts, and improves the overall discretion of the project. Among cannabis growing accessories, this replacement has a direct impact on efficiency and operating costs.
An effective Indoor growing plan combines filtration + recirculation. The CAN-LITE 4500 Filter Sleeve keeps the activated carbon clean for longer, stabilizes airflow, and facilitates the calibration of extractors, ducts, and silencers for stable and discreet microclimates.
It is used to protect the carbon filter against particles, prevent blockages, maintain 4500 m³/h airflow and prolong the lifespan of the filtration set. It also reduces dust buildup in ducts and fans, improving hygiene and overall system performance.
Considered an essential maintenance part among indoor growing accessories, this pre-filter allows you to work at the sweet spot of the filter curve, with lower pressure loss and better response to odor peaks. It fits intensive production rooms and cheap indoor grow tents, reinforcing odor control strategies without complex investments.
Recommended use from system start-up and whenever signs of saturation appear: increased external odor, noticeable drop in airflow, darkened fabric, or increased extractor noise due to overexertion. After pruning, transplants, or work that raises dust, a visual inspection and cleaning or replacement if necessary is advisable.
Turn off extraction and cut power. Remove the previous cover by sliding it out. Place the CAN-LITE 4500 Filter Sleeve from the blind end of the filter until the cylinder is completely covered. Secure both ends with rubber bands or clamps to prevent 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.
