These cartridges are compatible within whole house/high flow filter systems. These filter systems are designed to remove contaminants from the entire water supply to your home – providing near pure water to all the faucets/showers in the residence.
The micron rating of a filter cartridge determines the ability of the filter’s media to remove contaminants by the size of particles it is exposed to. For example, a filter that is marked or rated “10 micron” has some capability to capture particles as small as 10 micrometers. Although, the micron rating does not determine the exact efficiency of contaminant holding capability of the filter, it will help you determine which filter is most suitable according to your water supply.
