Can-Filter Can-Lite Active Carbon Filter - 12in - 1800 CFM

Grow Room Carbon Filtration for High-Airflow Ventilation, 1800 CFM

Odor control only works as well as the filter can keep up with airflow, and undersized or poorly perforated filters choke a ventilation system down or let odor pass through unfiltered. The Can-Lite active carbon filter packs 100% Australian granulated carbon into an aluminum housing with a 51% open perforation rate, so air moves through the carbon bed at volume instead of bottlenecking at the filter.

This 12in model is rated for 1800 CFM, sized to match mid-size grow room exhaust systems within the broader Can-Lite line, which spans ratings from 89 to 3000 CFM across different diameters.

Key Features & Benefits

• 100% Australian Granulated Carbon — captures odor compounds as air passes through the filter bed
• 51% Open Perforation — supports strong airflow through the filter without sacrificing odor capture
• Aluminum Top, Bottom & Flange — durable construction built to withstand continuous high-CFM airflow
• 1800 CFM Rating at 12in — matched to mid-size grow room exhaust systems
• Made in North America — manufactured in a dedicated carbon filter production facility

Who Should Use the Can-Lite 12in 1800 CFM Filter

This filter fits grow room operators whose exhaust fan is rated near 1800 CFM and who need a carbon filter that will not become the bottleneck in the ventilation system, whether in a home grow tent or a small commercial room.

Frequently Asked Questions

What carbon does the Can-Lite filter use?

It uses 100% Australian granulated carbon packed into the filter body to capture odor compounds as air is pulled through. This carbon source is used across the Can-Lite line regardless of filter size.

Why does the open perforation rate matter?

A 51% open perforation rate lets air pass through the carbon bed with less resistance than a tightly perforated housing, which helps the filter keep up with a fan rated near its 1800 CFM capacity. Too little perforation would restrict airflow and strain the connected fan.

How do I know if the 12in, 1800 CFM model is the right size for my room?

Match the filter's CFM rating to your exhaust fan's rated output, since the Can-Lite line spans ratings from 89 to 3000 CFM across different diameters. Running a fan that significantly exceeds the filter's rating reduces both airflow and odor control performance.

How long does the carbon last before it needs replacing?

Carbon filters gradually lose odor-capture capacity as the carbon bed becomes saturated, with actual lifespan depending on airflow volume and odor load rather than a fixed date. Many growers plan on replacing carbon filters roughly once a year in continuous-use rooms, checking performance periodically to confirm.

What is the filter housing made from?

The Can-Lite filter uses an aluminum top, bottom, and integrated flange, chosen for durability under continuous high-airflow operation. It ships shrink-wrapped and boxed for handling.
