Buying Guide

Match filter type to your hookup

Choose inline filters for quick, tool-free hookups and 10" cartridge filters for under-sink or dedicated housings to ensure compatibility with your RV plumbing

Check filtration media

Carbon block reduces chlorine and taste, while GAC+KDF blends target chlorine, heavy metals and microbial growth—pick media based on water source quality

Consider micron rating and flow

Lower micron ratings (finer) remove smaller particulates but can reduce flow; balance sediment removal (e.g., 20-micron prefilter) with sufficient water pressure for showers and appliances

Evaluate pack size and cost per filter

Buying multi-packs (4-pack, 3-pack, 2-pack) like those offered by Camco, Neo-Pure and others lowers cost per replacement and is practical for long trips or seasonal use

Look for construction and safety features

Prefer lead-free fittings, BPA-free housings and well-sealed inline connections to avoid contamination and leaks during travel
