The Culligan RV-500A Inline RV Filter has been replaced with the compatible Culligan RV-700 and is a compact external water filter cartridge used to fill the water tanks of recreational vehicles (RVs), campers, boats, trailers, motor homes, and other large water tanks with filtered water. Using granular activated carbon, it reduces the bad taste and odor of chlorine as well as sediment, dirt, rust, limescale, sulfur odors, sand, silt, and other common impurities.

The Culligan RV700 compatible pre-tank RV filter features Level 1 basic filtration and comes in a slim design which is simple to use (no tools required) with your RV, boat, camper, and more. It will fit all standard 3/4" garden hoses for quick and easy filling of water tanks.
