Filters are used in whole house system. They filter city water but we live at a dead end so we get a lot of sediment/rust. I use a 50 micron element in the primary filter and a 20 micron element in the secondary filter. Works perfectly. Good clear water. Between 2 and 3 months the water pressure will drop. I know it's time to change the filters. I've tried other types of filters, but none filter as well and for as long as membrane solutions.
