Vickmons KW1 RV Water Filter Replacement 2-Pack — KW1-Compatible Coconut Shell Carbon Block, 10,000-Gallon Life

Vickmons KW1 RV Water Filter is a high-capacity replacement cartridge that fits WaterPur KW1-compatible RV systems to reduce chlorine, VOCs, sediment and rust for up to 10,000 gallons.

Whether you live full-time in an RV or take seasonal road trips, clean water on board matters. This two-pack of Vickmons KW1 replacement filters uses a dense coconut shell carbon block and dual o-ring seals to maximize contact time and prevent bypass, improving taste and odor while removing fine particles and common contaminants. The cartridges are sized for built-in RV housings that accept KW1-style elements and deliver a practical flow rate without sacrificing filtration performance.

How does this filter improve water taste and smell on my RV?

The thick coconut shell carbon block in the Vickmons KW1 increases adsorption of chlorine, volatile organic compounds (VOCs), and other taste- and odor-causing chemicals. Its high surface area and contact time capture these molecules more effectively than granular carbon, producing cleaner, crisper water at sinks and faucets.

• Thick-wall coconut shell carbon block for enhanced CTO (chlorine, taste, odor) reduction
• Reduces VOCs that cause chemical tastes and smells
• Improves drinking water flavor without chemical additives

Will this cartridge fit my existing RV water filter housing?

The Vickmons KW1 is designed as a direct replacement for WaterPur KW1 and similar Forest River KW1 / FRE-10-BN style cartridges used in many RCS/FR1 and FRE-10 canisters. It matches the common KW1 form factor and includes dual o-rings for a secure seal, but it is not compatible with FRE-10-GN or FRE-10H housings.

• Compatible with WaterPur KW1 and Forest River KW1 / FRE-10-BN cartridges
• Fits many Forest River RCS/FR1 and FRE-10 style housing canisters
• Not a replacement for FRE-10-GN or FRE-10H housing parts

How long will each filter last and what are the performance specs?

Each Vickmons KW1 cartridge is rated for up to 10,000 gallons depending on feed-water quality and usage patterns, providing a reliable service life for most RV users. The element has a 5 micron rating, a flow capacity of approximately 2.5 gallons per minute, and operates across a broad temperature range for both summer and winter travel.

• Service life: up to 10,000 gallons (varies by water quality)
• Micron rating: 5 µm for fine sediment and rust particle reduction
• Flow rate: ~2.5 GPM with minimal initial pressure drop (about 2.6 PSI)
• Operating temperature: 40–165°F (4.4–73.8°C)

What design features prevent leaks and ensure full filtration?

Vickmons built dual o-rings into the KW1 cartridge to eliminate bypass paths that can allow unfiltered water through standard single-seal designs. The robust cartridge body and precise dimensions maintain a tight fit inside compatible housings so all water is forced through the carbon block.

• Dual o-ring sealing system prevents water bypass
• Accurate OEM-style dimensions for consistent housing fit
• Durable cartridge casing withstands normal RV vibration and handling

Who is this for: The Vickmons KW1 RV Water Filter 2-pack is aimed at RV owners and renters who need a high-capacity, OEM-compatible replacement element that improves drinking and cooking water quality. It’s ideal for Forest River, Rockwood, Flagstaff, GeoPro, EPro, Roo, and Shamrock model owners using KW1-style housings who want longer life, better taste, and dependable sealing. If your system uses FRE-10-GN or FRE-10H parts, choose the manufacturer-specified replacement instead.
