Charco Filters Plus Activated Carbon Filter - 8 x 20-in - 8-in Flange

Cleaner Exhaust Air for Indoor Rooms - 8 x 20 in

Odor leaving a grow tent or room is a constant problem for indoor growers, and untreated exhaust air can also carry airborne particles. This filter passes air through virgin, coal-based activated carbon to reduce odor before the air leaves your space. The distributor rates it at up to 99.5% odor removal, and the flange comes pre-installed.

The 8 x 20-in size suits a regular indoor grower running a single tent or dedicated room with 8-in ducting. It also suits a small commercial room that needs a compact inline filter.

Frequently Asked Questions

Q: How do I connect this filter?
A: The 8-in flange is already installed. Slide your 8-in ducting over the flange and secure it with a clamp. Place the filter on the intake or exhaust side of your fan.

Q: How long does it last?
A: The distributor lists an average lifespan of 1.5 years. Actual life depends on air quality, humidity and run time.

Q: What does CFM mean?
A: CFM is cubic feet per minute, a measure of airflow. This filter is rated at 548 CFM, so match your fan to that rating.

Q: Is a pre-filter included?
A: Yes, the distributor lists an included pre-filter. It collects larger particles and helps protect the carbon.

Q: How does carbon filtration compare with other odor control?
A: Carbon adsorbs odor molecules from the air itself. Masking sprays only cover odor, so carbon filtration is the usual choice for continuous control in enclosed rooms.

Q: What temperature can it handle?
A: The maximum operating temperature is listed at 180 °F. This covers typical exhaust conditions in indoor rooms.
