On-the-Road Water Filtration and Purification

Compact, simple and efficient Seagull IV and Nature Pure systems are the “go-to choice” for the best in potable water purification and filtration.


  • The Nature Pure drinking water system is especially suited to RVs, small boats, and icemakers. Because it has no V-clamps, shear rods or separate pressure vessels, changing filter canisters couldn’t be easier.

  • Nature Pure Select QC2-PB system includes an interface with tethered sanitary by-pass connector, a NSF42/53 Nature Pure PB2QC canister, connection lines (2), plastic tee, cap nut, and a point-of-use LFP chrome faucet with ceramic disk valving.

  • The Seagull IV X-1B/F/KFE system is intended for drinking water or icemakers on RVs and small boats. The stainless steel canister installs easily beneath a sink or countertop and ties into the onboard water connection. The filter lasts about a year and is easily changed. Faucet options available. Includes metal mounting bracket and connection lines.

  • Manufactured to the same exacting standards as all Seagull IV systems, Select X1-PB is designed for microbiologically safe water sources where Lead removal is a primary concern. In addition the exceptional removal of water-borne Cysts, Particles, and Foul Tastes/Odors from your drinking water means Select X1-PB is your first choice for providing safe drinking water that is free of lead contamination. Registered for residential applications in California with the State Water Resource Control Board.

  • The Seagull IV X-2B system doubles the capacity and throughput of the X-1B and is the best choice for large vessels with higher water filtration requirements. Its stainless steel housing fits easily beneath the sink or countertop and ties into the mains water connection. The filter lasts about a year and is easily changed. Faucet options available. Includes metal mounting bracket and connection lines.

  • Manufactured to the same exacting standards as all Seagull IV systems, Select X2-PB is designed for microbiologically safe water sources where Lead removal is a primary concern.
