The HEPA filter in your Shark Navigator NV501 vacuum cleaner traps microscopic particles like dust mites, pollen, and pet dander, ensuring clean air output. Over time, these filters become clogged, reducing suction power and potentially releasing trapped particles back into the air. Regular replacement every 3 months maintains optimal performance and indoor air quality.
