Can-Filter Pre-Filters

The pre-filter acts as a first line of defense, capturing larger airborne particulates like dust and pollen before they reach your main carbon filter. By trapping this debris, it prevents the primary filter from clogging prematurely, which significantly extends its overall lifespan and maintains optimal airflow.

These pre-filters are specifically engineered with a low-resistance mesh construction to ensure minimal impact on airflow. While any filter will create slight resistance, this design is optimized to keep your system running efficiently without forcing your fan to work harder.

You should match the pre-filter model number to your existing Can-Filter unit. We offer options including HGC700725, HGC700730, and HGC700735, which correspond to different filter sizes; check your current filter's specifications or model label to ensure a proper fit.

Replacement frequency depends on your environment's dust and pollen levels. As a general rule, inspect the pre-filter visually every few weeks; if you notice a visible layer of dust or debris buildup, it is time to replace it to maintain peak performance.

These pre-filters are designed as disposable replacements rather than washable filters. Attempting to wash the mesh can degrade the material and compromise its ability to effectively trap particulates, so it is best to replace them once they become dirty.
