Tetra Whisper 30 - 60 Air Pump, Felt Air Filters 4 Pack

First, I admit I purchased the incorrect size. That's on me and they still work. I hadn't realized my pump had these little filters until it started making a crazy noise. It took me a while to find Aqua Parts Online and, boy howdy, so glad I did. There are parts on here that will help with my aquarium, lizards, and gardening setups. These filters came quickly and well packaged. Good prices, too. Grateful folks like this exist.
