All filtering is done inside the MotorCoach. One(standard 10") canister contains a 4 micron sediment filter that flows @ 3-5 gal/min to fill the 55 gal fresh water tank and prevent build up anywhere in the system.
Before the pump is a standard SS filter screen to prtect the pump, and the second filter canister is before the drinking spout over the sink. Standard 10" canisters of many kinds can be found @ the RV water Filter Store or Real Goods, both on the internet and I am sure there are others.
