The Brondell
Coral UC300 Three Stage is part of the
Water Filters test program at
Consumer Reports. In our lab tests, Under-Sink Water Filters
models like the Coral UC300 Three Stage are rated on multiple criteria, such as those
listed below.
Flavor and Odor Reduction:
A measure of how effectively the filter removed flavor taints, along with the resulting odor taints, that CR added to plain water with minimal intrinsic flavor and odor (the "control" water). The test measured how close the flavor and odor of the filtered water was to that of the control water.
Flow rate:
The volume of water, in gallons, that passes through the filter each minute.
Clogging:
reflects if/how the filter's flow rate slowed over the course of the cartridge's lifespan
