The Tetra Whisper Impeller Assembly replaces the impeller for the Whisper Power Filter PF60, 3, 4, Whisper Advanced PF30-60 and Triad 3000 filters. Replacing an old impeller is essential to keep your filter running powerfully and efficiently.
Old impellers can result in decreased water flow, poor circulation, and, in some cases, even an unpleasant grinding noise. Replace the impeller to reinvigorate your filter with strong, silent water pull and maximum circulation.
