“Our customers are very happy with their Atlas Filtri systems. We install so many of them on water heaters in Frisco, Texas."   - Trident Plumbing, Frisco, TX

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
