The GLACIER FRESH RV/Marine Water Filter is designed to improve the taste and safety of water used from garden hoses, especially for RVs, boats, and outdoor activities.

The filter uses a combination of granular activated carbon and a special KDF material to also help reduce fluoride, which is a nice extra for protecting health. One big plus is its long filter lifespan — it can last up to three months or a full camping season, so you won’t need to replace it often. The included flexible hose protectors help prevent kinks and leaks, making installation and daily use easier and more reliable.

The filter fits standard water hoses, making it versatile for various uses beyond RVs, like gardening or pet water bowls.
