If you want to put your mind at ease that you’re getting clean water in your camper, the Culligan RVF-10 might be just what you need.
It’s a pre-tank water filter system for RV use that allows you to enjoy better-tasting water (almost) free from foul tastes and odors – think chlorine – as well as sediment.

Culligan RVF-10 RV Water Filter – Key Features
How does the Culligan RVF-10 work? The cartridge inside is rated at 5-micron. This means that it will remove more or less all particulates that have a size of 5 microns or larger.
Above that, the filter exceeds at free chlorine elimination thanks to the granular activated carbon media.
The filtration capacity is as low as 250 gallons or 3 months which is not a whole lot of water, unfortunately. This has to do with the filtering media inside.
The good news is that replacement cartridges are super affordable.
Other than that, you get a limited warranty for a period of 5 years.
RVF-10 Pros
Additional benefits are the unit’s slim design for easy storing and the simple installation.
Pro Tip: Since the Culligan RVF-10 doesn’t come with a bracket, a free “mounting option” is to put the unit in a bucket. The hoses on either side will hold it in place – easy!
What’s more, apparently this filter is great for home brewing as many reviewers reported on Amazon.

Setup
Hooking up this filter is a piece of cake and won’t take you more than a couple of minutes. You want all the details? Sure, here are some step-by-step instructions:
Please note: The hose that connects to the water supply is not part of the deal!
- Start by wrapping the ⅜” fitting on the female hose adapter with Teflon tape (included).
- Screw the fitting into the system’s inlet port.
- Repeat the process with the male hose adapter. First wrap it with Teflon tape. Then screw it into the outlet side of the system.
- Use a wrench to firmly tighten both connections. Be careful not to over-tighten. About one thread should remain visible, says Culligan.
- Attach a sanitary hose (not included) that’s connected to a water supply to the filter inlet.
- Turn on the water for approximately one minute to flush any loose carbon fines out of the cartridge.
- Connect the outlet to the RV storage tank inlet using the short hose (included).
The Package (Parts)
- D-15 cartridge
- ¾” hose couplings
Usage & Maintenance
In terms of usage, there are 2 things that you have to keep in mind. For one, the RVF-10 must be protected from freezing temperatures. Otherwise the housing may crack and start leaking.
Secondly, if you don’t use the filter for an extended period of time, remove the cartridge and drain any excess water. Let the cartridge air dry before storing. Remember to flush before next use.
As far as maintenance is concerned, the filter cartridge requires periodic replacement:
- If the system is still connected to the water supply, turn it off and depress using the red pressure relief button.
- Now you can open the housing.
- Remove the old cartridge.
- Rinse out the housing and cap. You also want to scrub the inside with mild soap water and a non-abrasive sponge. Rinse thoroughly afterwards.
- Clean rubber O-ring and groove.
- Lubricate O-ring with clean petroleum jelly before placing it back in the groove. Make sure that it’s properly seated to prevent possible leaks.
- Insert new cartridge into housing and screw the housing back on. Be careful not to over-tighten.
- Before running water into your RV’s storage tank, flush the filter for approximately 1 minute to remove any loose carbon fines that may be present in the carbon cartridge.
Annual filter cost: Average compared to other RV filters.

RVF-10 Cons
We wouldn’t necessarily say that the Culligan RVF-10 is prone to leaking, but you have to make sure that you are using enough sealing tape on the connections to prevent a possible disaster.
Actually, it might be a better idea to replace the cheap plastic fittings that tend to break with brass.
Also, double-check that there is an O-ring (one user had his missing) and that it sits tight. Otherwise water will spray out the gap between the housing and the top cap.
