Shark Navigator Filter

This filter is specifically engineered for the Shark Navigator models NP318, NP319, and NP320. Please check the model number printed on your vacuum's base or rating label to ensure a match before purchasing.

HEPA stands for High-Efficiency Particulate Air. This filter is designed to capture fine dust, pollen, and allergens that standard filters might miss, helping to improve the air quality in your home as you vacuum.

While replacement frequency depends on how often you vacuum and the amount of debris you pick up, we generally recommend replacing the filter every 6 to 12 months. If you notice a drop in suction or the filter appears visibly discolored or clogged, it is time for a new one.

This specific filter is designed as a replacement component for optimal filtration efficiency. While some vacuum filters are washable, HEPA filters often lose their effectiveness after being washed, so replacing it is the best way to ensure your vacuum continues to perform at its peak.

A precise fit is critical because it prevents air bypass. If the filter doesn't seal perfectly, dirty air can escape around the edges of the filter and back into your room, defeating the purpose of having a HEPA-grade filtration system.
