GLACIER FRESH RV/Marine Inline Water Filters 4-Pack with 2 Hose Protectors — GAC+KDF, 97.9% Chlorine Reduction

This four-filter set from GLACIER FRESH is designed for inline attachment to standard water hoses used in RVs, boats, and outdoor living. Each cartridge blends granular activated carbon (GAC) with KDF media inside a reinforced, food-grade housing. Independent laboratory testing reports up to 97.9% chlorine reduction and a 20-micron nominal rating, while the included flexible hose protectors ease connections and reduce kinking.

How does this filter improve the taste and smell of campsite or marina water?

The filters use selected GAC (granular activated carbon) plus Kinetic Degradation Fluxion (KDF) media, which adsorb and reduce chlorine and some taste-and-odor compounds. The result is water that typically smells and tastes cleaner coming from shore or hookup supplies. This is a practical, not medical, improvement in sensory quality.

• Independent lab testing shows up to 97.9% chlorine reduction*
• GAC media targets organic taste-and-odor molecules
• KDF supports longer carbon effectiveness in inline setups
• 20-micron nominal rating helps trap visible particles and sediment

How long will each filter last while camping or boating?

Filter lifetime depends on water quality and flow, but each cartridge is built for season-long use under typical recreational conditions. GLACIER FRESH rates the inline units to last up to about three months in regular RV or marine use, which makes the 4-pack convenient for extended trips or frequent hookups.

• Designed for an entire camping season for many users (approx. 3 months)
• Pack of four covers multiple hookups or replacement intervals
• Reusable housing is not required—cartridges are disposable per manufacturer guidance

Will this fit my hose and how do the flexible protectors help?

The cartridge uses standard garden-hose threaded ends so it connects to most RV, marine, and outdoor hoses without adapters. The two flexible hose protectors included with the set reduce stress on fittings and minimize kinking at the connection points, extending hose life and keeping flow steady.

• Standard threaded ends for easy inline installation
• Two flexible protectors reduce strain on connectors and prevent kinks
• Lightweight, reinforced food-grade plastic housing resists bursting

What contaminants does this filter target and what are its limitations?

The GLACIER FRESH media targets chlorine, taste-and-odor compounds, and larger particulate sediment down to a 20-micron nominal rating. The formula includes GAC and KDF to address a range of common hookup water issues, though it is not certified to remove all possible contaminants (e.g., viruses, dissolved salts, or some heavy metals). Always test water when in doubt and replace cartridges per use conditions.

• Reduces chlorine (tested up to 97.9% reduction)* and organic tastes/odors
• 20-micron nominal filtration for sediment and visible particulates
• Contains selected GAC and KDF; not a substitute for specialized contaminant removal systems

Who is this for: These inline filters suit RVers, boaters, campers, and homeowners who want an easy, portable way to improve shore or hose water taste and reduce chlorine exposure. The 4-pack with two flexible hose protectors is ideal for seasonal travelers, fleet owners, or anyone who needs multiple filter changes across extended trips or shared equipment.

Notes: Lab results referenced are from independent testing on chlorine reduction. Filter performance varies with water quality, flow rate, and maintenance. Replace cartridges according to observed flow reduction or after heavy usage.
