“I have an RV that i want to install a whole system filter in before or after the pump that will take out the smells as well as, more importantly, the cysts. my pump pushes approx 2.8gallons/min and i dont want to lessen the flow through the pipes making the shower weak. is this even possible? ive seen filters on-line that say they flow approx 2gal/min but does the inlet pressure reduce this? is the flow calculated through a city pressure line? Is it even possible to do this or will anything I put in line reduce the flow to a trickle?”
Aside from the flow in gallons per minute, do you happen to know what your pressure is in PSI? For cyst removal, we recommend an 1-micron absolute-rated filter. Odors are different though, your best bet for that probably be an activated carbon filter for improved taste and odor. So, you could use both filters, one installed after the other.
These cartridges shouldn’t reduce your actual flow rate too much, because they’re designed to accommodate for at least 6 gpm.
See below for the recommendation:
