RV life offers endless adventure, freedom, and a front-row seat to the beauty of the outdoors. But with every new destination, the quality of the water changes. To protect your health and your rig, one of the simplest and most effective steps is to routinely replace your RV water filters.

Why Changing Your Water Filters Matters

Your RV water filter is your only defense against sediments, heavy metals, bacteria, and other harmful contaminants. When a filter becomes clogged or overused, it can lead to:

• Bacteria Growth

• Contaminants Passing Through into Your Water

• Reduced Water Pressure

• Unpleasant Taste or Odor

According to the Centers for Disease Control and Prevention (CDC), untreated or poorly filtered water can carry harmful bacteria that pose serious health risks. Routine maintenance helps keep your water cleaner and your family safer.

How Often Should You Change Your RV Water Filter?

As a general rule, RV water filters should be replaced every 3–6 months, depending on usage and the quality of water you're filtering.

• Carbon Block Systems: Replace every 3–6 months

• UVC Systems: Replace pre-filters regularly and monitor UVC lamp lifespan based on hours of operation

• Heavy Usage or Poor Water Quality: Replace more frequently to ensure clean, safe water

Always check your manufacturer's recommendations, as system-specific guidelines may vary.

Signs It’s Time to Change Your Water Filter

Even with general timelines in mind, there are some telltale signs it’s time to swap out your water filter:

• Changes in Taste or Smell

• Lower Water Pressure

• Sediment Buildup

• Discoloration or Slimy Filter

• It's Been Longer Than the Recommended Replacement Period

When in doubt, replace all filters simultaneously to reset your system and ensure consistent performance.

Factors That Affect Filter Lifespan

Not all RV adventures are the same, and several factors influence how often your filters need replacing:

• Water Sources: Some areas have higher levels of sediment or contaminants.

• Frequency of Use: Full-time RVers need to change filters more often than part-time users.

• Type of Filtration System: Multi-stage systems may offer longer-lasting filtration compared to basic point-of-use filters.
