Both filters are washable, and should be washed every 30 days to ensure peak cleaning performance, and replaced every 3-6 months depending on how active the home is. The Felt Filter is located underneath of the Foam filter, and captures a fine dust, where the foam filter captures larger debris. These filters are located directly below the dust cup and protect any debris from going into the motor. Both filters may be washed and reused several times before needing to be replaced. IMPORTANT make sure that both filters are 100% completely air dried before reusing them in your vacuum to avoid permanent damage to your vacuum. Some prefer to have an extra set of spare filters to use while waiting for them to dry. 4 Genuine Shark Euro-Pro Navigator, and Navigator Pro Replacement Filter Kits, Shark Part XFF350.
