Pfister Faucet - Concealed Aerator Tool

The very bottom of the faucet doesn’t just unscrew? I can usually unscrew them with my hands or use a rag with channel locks.

I have been able to get some skinny needle nose pliers to work. I have also just broken the filter and pulled it out that way. Make sure you keep the filter and bring it to Lowe’s so you know what size to get.

I bought some sort of universal one from ace hardware a few months ago that was the correct size, but the threaded part was too long to fit in my faucet, so I trimmed it with a razor blade and it works fine
