Can-Filter Can-Lite Pre-Filter

Yes, a pre-filter is essential if you want to get the full lifespan out of your carbon filter. It acts as a barrier that catches dust and debris, preventing those particles from clogging the activated carbon bed and reducing its effectiveness.

You should replace or wash the pre-filter whenever you notice a visible buildup of dust or if you see a drop in your system's airflow. In dusty environments, check it monthly; in cleaner spaces, it may last several months.

These fabric pre-filters are washable, which helps extend their utility. However, they will eventually degrade, so keep a spare on hand for when the fabric becomes too worn or thin to effectively trap particles.

These are specifically designed for the Can-Lite series. While they might physically fit other brands with similar diameters, we recommend sticking to the Can-Lite line to ensure the proper fit and airflow characteristics.

A clean pre-filter has a negligible impact on airflow. However, if you let it get completely clogged with dust, it will restrict air movement, so regular maintenance is key to keeping your system running efficiently.
