FAQs

How often should I wash the pre-filter?+

Will this pre-filter reduce my fan's airflow?+

No, the pre-filter is made from a highly breathable polyester material specifically designed to capture particles without restricting the airflow of your ventilation system.

Is this compatible with other brands of 8" carbon filters?+

This pre-filter is specifically designed for a perfect fit on AC Infinity 8" carbon filters. While it may fit other brands, we cannot guarantee compatibility or optimal performance.

How do I wash the pre-filter cloth?+

You can wash it by hand with mild soap and water or put it in a washing machine on a gentle cycle. Always let it air dry completely before reinstalling it on your carbon filter.

What's the benefit of using a pre-filter?+
