Can FV Intake Filterbox – Fleece Pre-Filter for Dust

Stop dust, pollen and bugs at the intake, before they ever reach your grow room

The Can FV Filterbox is a galvanised steel intake filter that sits on the fresh-air side of your ventilation, catching dust, pollen, insects and other airborne debris before it can settle on leaves or clog your carbon filter. A MERV-5 fleece filter insert handles the filtering, held in place by quick-release toggle fasteners on top of the housing so it can be swapped in seconds without tools.

Key Benefits

• Galvanised steel housing for a durable, corrosion-resistant build that lasts for years of continuous use.
• MERV-5 fleece filter insert blocks pollen, dust, insects and other particulate from entering your intake ducting.
• Toggle-fastened lid gives tool-free access for fast fleece changes and cleaning.
• Low airflow resistance so intake CFM stays close to your fan's rated output.
• Protects downstream equipment — keeping dust off leaves, out of carbon media and away from fan blades.

A dirty or unfiltered intake is one of the most common causes of a dusty grow room, clogged carbon filters and pest introduction from outside air. Fitting a Filterbox on every intake point keeps the whole room cleaner and reduces how often the main carbon filter needs replacing.

How to Use

Fit the Filterbox directly onto your intake ducting or wall vent with the flange matched to your duct diameter. Check the fleece insert every 2-4 weeks depending on how dusty the environment is, and replace it once it looks visibly grey or airflow starts to drop. Replacement fleece inserts are sold separately and sized to match each Filterbox.
