Ready for a Refresh? Knowing When Your RV Water Filters Need Replacing

This post was updated on March 19th, 2024

Every seasoned RVer knows that the journey’s success often hinges on the basics. And access to clean, purified drinking water tops that list. RV water filters serve as the first line of defense. They help to ensure that the water flowing through your RV’s taps is not only safe but also tastes great, no matter where your travels take you.

However, as crucial as these RV water filtration systems are, their efficiency isn’t everlasting. Timely recognition of when to replace these essential components is key for ensuring continuous access to high-quality water. This guide explores the expected lifespans of popular RV water filter systems, arming you with the insights needed to maintain pristine water quality throughout your nomadic adventures.

Inline RV Water Filters

  • What They Do: Inline water filters are designed to be attached directly to the RV’s water hose. They offer a convenient way to filter water before it enters your RV. They primarily remove sediments and chlorine, improve taste and odor, and can reduce contaminants like VOCs.
  • Installation: Easy to install, they connect between the RV’s water intake and the water source hose without needing tools for most models.
  • Popular Brands: Camco TastePURE and Culligan RV-800 are widely recognized for their effectiveness and affordability.
  • Lifespan: On average, 3-6 months, but this can vary with water quality and consumption.
  • When to Change: Reduced water flow, unpleasant taste, or odor indicates it’s time for a replacement.

Canister RV Water Filters

  • What They Do: Canister systems offer multi-stage filtration, allowing for a more comprehensive purification process. They can include sediment filters, activated carbon filters, and more specialized filters to target specific contaminants like cysts and giardia.
  • Installation: More complex than inline filters, they usually require mounting and connecting multiple canister units in sequence.
  • Popular Brands: Clearsource and RV Water Filter Store offer high-quality canister systems known for durability and performance.
  • Lifespan: Filters within the system should be replaced every 3-6 months, depending on use and the initial water quality.
  • When to Change: Noticeable decrease in water pressure or quality. Some systems have pressure gauges to help determine when a filter change is needed.

UV Sterilizers for RVs

  • What They Do: Utilize ultraviolet light to kill or inactivate microorganisms, providing an extra layer of protection against bacteria, viruses, and parasites without adding chemicals to the water.
  • Installation: Integrated into your RV’s water system after sediment and carbon filters. Requires a power source for the UV light.
  • Popular Brands: Acuva offers efficient UV sterilization solutions suitable for RV use.
  • Lifespan: The UV bulb typically needs replacing approximately every 12 months.
  • When to Change: A decline in water quality or an indicator on the unit can signal the need for bulb replacement.

Additional Tips

  • Microns Matter: The effectiveness of a filter is often gauged by its micron rating, where lower micron ratings equate to finer filtration, enabling the removal of smaller particles and organisms from the water.
  • Activated Carbon: The use of activated carbon in water filtration systems is essential for removing chemicals that negatively impact water’s taste and odor, making systems that utilize activated carbon or carbon block filters preferable for achieving the best water quality.
  • Certifications: Choosing water filters that have NSF certifications is crucial as it assures that the filters meet stringent health and safety standards, providing an additional layer of trust in the water’s purity.
  • Maintenance: To maintain the highest water quality, it’s important to regularly inspect all types of water filters for any signs of clogs or buildup and adhere to the manufacturer’s recommendations for timely filter replacement.
