Please school me on water filter options

I have not done intense testing but I suspect the flow problem is as Bud mentioned the regulator not the filter. I'm OK with the reduced flow when using my holding tanks as it help to prolong the time between dumps. If I just use the blue filter, flow is great. Add the brass regulator and it makes a big difference.

Have you tried a different filter in the canister as if like the one I had at my last house they had several options in regards to particle size captured.

What you could do is use two pressure regulators, two Camco inline hose filters, get two "Y" connectors, a male to male adapter, two female to female adapters, and run both the filters and regulators in parallel. Twice the flow, same amount of pressure. You can keep the inside filter, and because the inline hose filters will get the worst stuff, the inside filter will last a lot longer.

THIS is the filter system I use. It gives me 8 GPM which is more than enough water for any RV. I usually use the AP110 cartridge for sediment, but will use any one of the AP110, AP124, AP117, AP420 cartridges depending if there are other things I am trying to filter out. All of these cartridges give me excellent flow. The system comes with a stainless steel bracket which I mounted on my RV right next to the city water inlet. I hang the unit here when I hookup. You can also just lay it on the ground and it will filter fine.

The filter will never have an effect on the pressure -- only on the flow. Go to Aqua Pure's website and look for the filter type that suits your needs as far as what you are trying to filter out. Then, look to see which model will give you the best flow (GPM) . Most of the in-line hose-type filters have a very dense medium that severely restricts the flow, and you don't have much choice of what, exactly, you are filtering out of your water. Your best option is to buy a brand like Aqua Pure, which has been around for years, who offers many options of filtering medium and flow rates. You will always be able to buy replacement filter cartridges for an Aqua Pure filter.

Doesn't really matter where the filter is located along the run,it will still lower the pressure where ever it is.

Flow is likely the small in line regulator.
Some canister style filters have a by pass. What is make and model of the filter inside the rig.
