Can-Filter Original Carbon Filter without Flange CAN 100 840 CFM

Thick-Bed Flangeless Carbon Filter for Maximum Lifespan, CAN 100, 840 CFM

A thin carbon bed clogs and channels air around the carbon faster than a thick one, cutting service life short. The Can-Filter Original addresses that with the industry's thickest granular carbon bed at 2.5 inches, creating maximum contact time between contaminated air and virgin activated carbon. The CAN 100 model handles 840 CFM and is sold without a flange for flexible custom ducting configurations.

This packed-bed design has been the benchmark for activated carbon air filtration in controlled growing environments for over 30 years, delivering consistent, low-pressure-drop filtration without the channeling issues that affect pleated or thin-bed alternatives.

Key Features & Benefits

• 2.5in Granular Carbon Bed: The thickest carbon bed in the category means more activated carbon for air to pass through, extending contaminant capture capacity and lifespan.
• Packed Bed Design: Decades of proven performance with a granular packed bed that avoids the channeling issues of pleated or thin-bed alternatives.
• Virgin Activated Carbon: Made with granular virgin activated carbon, not recycled or reactivated material, for maximum adsorption capacity out of the box.
• 840 CFM Flow Rate: Sized to match your inline fan selection and maintain proper air exchange rates for the grow space.
• Without Flange: Flange-free design allows custom ducting configurations and adapters to fit a wide range of installation setups.

Who Should Use This

Serious cultivators who prioritize maximum filter lifespan and contaminant removal capacity over lighter-weight alternatives are the direct fit for the CAN 100 Original, sized for grow rooms requiring 840 CFM of clean, odor-free air exchange.

About Can-Filter

The Can-Filter Original has anchored Can-Filter's carbon filtration lineup for over three decades; Can-Filter, a Hawthorne Gardening Company brand also known for its Can-Fan inline fan line, continues to build the Original alongside its lighter-weight Can-Lite series.

Frequently Asked Questions

Why choose the Can-Filter Original over the Can-Lite?

The Original features a thicker 2.5in carbon bed and higher total carbon mass, giving it a longer service life and higher contaminant capacity than the Can-Lite. The Can-Lite trades some lifespan for a lighter weight and an integrated flange, so the Original is the better choice when maximum lifespan matters most.

How long will the Can-Filter Original last?

Service life depends on VOC load, airflow rate, humidity, and temperature. Under typical grow room conditions with a clean pre-filter in place, the Original's thick carbon bed can last 1-2 years or longer.

Does this filter come with a pre-filter?

No, the Original is sold without a pre-filter. Can-Filter MERV-5 replacement pre-filters are available separately and are strongly recommended to protect the carbon bed and extend service life.

When would I need a flange or adapter for this filter?

You'll need one any time your duct system isn't already fitted with a matching connection point, since the Original ships without a flange for flexible custom ducting. Order a compatible flange or adapter separately based on your specific inline fan and duct size before installation.
