SHARK Foam & Felt Filter

While these filters are washable, they will eventually degrade over time. For optimal suction performance, we recommend washing them every three months and replacing the entire set every six to twelve months, depending on your household's usage and pet hair levels.

This kit is specifically engineered for Shark upright models NV46, NV46C, NV36, NV36A, NV42, and NV44. Please double-check your vacuum's model number on the rating plate before purchasing to ensure a proper fit.

Simply rinse the foam and felt components under cold water until the water runs clear. It is crucial to let them air dry completely—usually for at least 24 hours—before reinstalling them to prevent mold growth or motor damage.

The dual-layer design serves two purposes: the foam layer traps larger particles and debris, while the felt layer acts as a secondary barrier to catch finer dust. Using both together ensures that clean air passes through to the motor, which protects it and maintains strong suction.

Yes, having a spare set is a smart maintenance strategy. Since the filters must be completely dry before use, keeping a second set on hand allows you to continue cleaning without waiting for the washed filters to air dry.
