Buying Guide: How to Choose RV Water Filters

How to Choose an RV Water Filter

Why Campground Water Is Questionable
Every campground pulls water from different sources with different treatment. What's "safe" in Montana might taste like a swimming pool in Arizona. A good filter evens the playing field.

### Filtration Types
Carbon Only: Removes chlorine taste, basic sediment. Entry-level but effective.
KDF (Kinetic Degradation Fluxion): Reduces bacteria, heavy metals, chlorine. Better protection.
Multi-Stage Systems: Sediment filter + carbon + KDF. Best overall filtration.

### Inline vs. Canister Systems
Inline Filters: Disposable, compact, affordable. Replace entirely when spent.
Canister Systems: Replaceable cartridges, better filtration, higher upfront cost but cheaper long-term.

### What to Filter For
Sediment: Visible particles, rust, sand
- Chlorine: Taste and odor
- Bacteria: Especially at older campgrounds
- Heavy metals: Lead, mercury from old pipes

### Flow Rate Considerations
Filters reduce pressure. Look for 2.5+ GPM flow rate to maintain usable shower pressure. Multi-stage systems often need a pressure regulator.

Frequently Asked Questions About RV Water Filters

Should I filter water going into my fresh tank or at the tap?

Both, ideally. An inline filter at the connection protects your tank and plumbing. A tap filter provides final filtration for drinking water.

How often should I replace RV water filters?

Inline filters every 3-4 months of regular use. Canister cartridges every 6 months. Always replace at the start of camping season regardless of use.

Do I need a filter if I only use bottled water for drinking?

Yes. Unfiltered campground water still goes through your RV plumbing, hot water heater, and potentially your ice maker. Filter protects the whole system.
