The HEPA Filter in your Shark Navigator NV356E traps dust, allergens, and other microscopic particles, ensuring clean air output. Over time, the filter accumulates debris and loses effectiveness. This can lead to reduced suction power, poor air quality, and potentially even damage to the vacuum's motor. Regular replacement every 3 months is crucial for optimal performance and longevity.
