Review on 🚿 Aquasana AQ-4125 Shower Filter Replacement Cartridge, White, 1-Pack by Vanessa Jones

I've been using this shower filter for a few years now with no problems and the water is better. However, my last filter was still leaving lots of fine black particles in the tub six weeks after installation. I wrote to Aquasan. After asking me a few questions about how I changed the filter, they sent me a replacement for free. That's good customer service. BUT I had the same problem for four weeks with a replacement filter - lots of black particles appeared on the bottom of the tub and often stuck to the bottom of the bath mat suction cups. I switched to another brand. FWIW I always carefully follow their installation instructions.
