Can furnace filters be cleaned and reused


Yes, furnace filters can be cleaned and reused, but it depends on the type of filter.

Disposable fibreglass or polyester filters are not meant to be cleaned and reused. Depending on usage and the manufacturer’s recommendations, they are designed to be replaced every one to three months.

On the other hand, some types of filters, such as washable electrostatic filters, are designed to be cleaned and reused. These filters are made of a material that creates a static charge when air passes through it, attracting and trapping particles.

To clean a washable electrostatic filter, turn off the furnace and remove the filter. Rinse the filter thoroughly with water, using a mild detergent if necessary, and let it air dry completely before reinstalling it in the furnace.

It’s important to note that even washable filters will eventually wear out and must be replaced. Check the manufacturer’s instructions for the recommended cleaning frequency and replacement schedule for your specific type of filter.
