Where the points went

The Solar Score weighs performance, build, value, safety and warranty. For a water filter, safety means lead-free fittings, stated reduction claims and certifications the listing names; the Beech Lane states lead-free brass fittings, the Clearsource states VirusGuard protection, and the Filterelated states FDA grade materials. One of the five listings states a warranty term: the Beech Lane at lifetime. The other four state no term. How we pick explains the weights.

How to choose the best rv water filtration system

Count the stages

Stages decide what the water passes through. The Filterelated system has three stages: a 1 micron sediment filter, a 5 micron carbon block and a GAC filter. The Clearsource also has three stages: a 5 micron filter, a 0.5 micron coconut shell carbon block and a VirusGuard filter. The Beech Lane and the OKBA are dual systems with 5 and 0.5 micron filters, and the VEVOR has three cartridges. For the gravity-or-pump question, see gravity vs pump water filter.

Read the micron figures

The micron figure sets what the filter catches. A 5 micron filter catches larger material such as sand and dirt, and a 0.5 micron filter catches smaller material such as chlorine, per the Beech Lane and OKBA listings. The Filterelated adds a 1 micron sediment stage, and the Clearsource notes that 0.2 micron filters are effective only against rare, larger size viruses, which is why its VirusGuard stage matters. No system here lists a 0.01 micron stage; that figure belongs to the more-picks systems below.

Fittings, flow and capacity

Fittings decide whether the system connects without a fight. The Filterelated, Beech Lane and OKBA systems use 3/4 inch fittings, the Beech Lane in lead-free brass, and the Clearsource uses stainless steel fittings. Flow and capacity are stated for the VEVOR only: a 3 GPM flow rate with stable pressure from 20 to 125 PSI and up to 80,000 gallons of filtration capacity. The Filterelated installs in about 5 minutes with a wrench included, and needs a rinse for five minutes before use.

System Stages Fittings
Beech Lane Dual Filter System 2 filters, 5 and 0.5 micron 3/4 in lead-free brass
Clearsource Ultra VirusGuard 3 stages, VirusGuard Stainless steel
Filterelated 3-Stage System 3 stages, 1 micron to GAC 3/4 in brass
VEVOR 3-Cartridge System 3 cartridges Not stated
OKBA Dual Filter System 2 filters, 5 and 0.5 micron 3/4 in brass

Warranty and replacements

Only the Beech Lane states a warranty term, a lifetime manufacturer warranty that covers product failure. The other four state no term, so the warranty line of the score is empty for them. Replacement filters are part of the plan either way: the Beech Lane filters can be replaced with any brand of the same specifications, and Clearsource replacement filters are listed as available. For filter life, see how long does water filter last.

Sizing Notes

  • Match the fittings to the hose: the Filterelated, Beech Lane and OKBA systems use 3/4 inch fittings.
  • Check the micron figures against the job: 5 micron catches sand and dirt, 0.5 micron catches smaller particles.
  • Rinse the Filterelated cartridges for five minutes before use, as the listing directs.
  • Check the flow and pressure the listing states: the VEVOR lists 3 GPM and 20 to 125 PSI.
  • Keep a spare set of cartridges: the Beech Lane filters can be replaced with any brand of the same specifications.

FAQ: power away from the grid

How often should I change a camper water filter?

The listings do not give a change schedule. The VEVOR lists up to 80,000 gallons of filtration capacity, and the Beech Lane filters can be replaced with any brand of the same specifications.

What is a good RV water filter?

The Beech Lane leads here on stated features: a lifetime warranty, lead-free brass fittings and dual 5 and 0.5 micron filters. The Clearsource adds VirusGuard protection against viruses, bacteria and cysts.

Does an RV water filter reduce water pressure?

The Filterelated listing states a low pressure drop, and the VEVOR lists stable pressure from 20 to 125 PSI with a 3 GPM flow rate. Check the flow and pressure figures on the listing before buying.

Do RV water filters regulate pressure?

None of the five systems here lists a pressure regulator. The VEVOR states stable pressure from 20 to 125 PSI, which is a flow figure, not a regulator.

How long do RV inline water filters last?

The listings do not state a service life in months. The VEVOR lists up to 80,000 gallons of filtration capacity.
