About Rainshow'r®


Rainshow'r® is the pioneer in the shower filter industry. We're located in Southern California in the city of San Gabriel. We've been designing and manufacturing shower filters for over 20 years and have thousands of long time customers (Testimonials).


We do not use, and will never use, activated carbon in our shower filters due to the inferior performance of carbon in a short-bodied, high temperature filter environment.


Rainshow'r® is committed to the idea that everyone deserves a safe, healthy, and chlorine free shower.
