Thrilled with how the installation went with my Atlas Filtri Duo system. Their kit comes with everything you need and makes this easy and clean to install. The water quality is amazing from the moment you start it up, and I cant say enough good things about this product. - Chase Piombo, General Plumbing Supply Co.

The filter arrived and I changed it out and the residual chlorine smell cleared right up. I think the issue with the aftermarket filter was threefold; one, the center opening is larger than the Atlas Filtri cartridge, so the guide in the housing couldn't center it properly. Two, the aftermarket filter was just a bit (1/8") shorter. And three, the aftermarket filter was probably of inferior quality. I will only use genuine Atlas Filtri cartridges from now on. - Roger Rheinheimer, Port Angeles, WA
