PUREPLUS RV Water Filter Replacement Combo 10" x 2.5" — 1µm KDF Carbon Block + 5µm Sediment, 2-Pack for Camper/Boat, BPA-Free

PUREPLUS 10" x 2.5" RV Water Filter Replacement Combo Pack provides two-stage protection for onboard water: a 5-micron sediment pre-filter plus a 1-micron KDF carbon block to reduce sediment, chlorine, odors and heavy metals.

Designed for RVs, campers and boats, this 2-pack of replacement cartridges fits standard 10" x 2.5" housings and PUREPLUS dual-stage systems. Together the polypropylene sediment element and the CTO carbon/KDF block deliver clearer, better-tasting water while protecting downstream plumbing and appliances. Built from food-grade, BPA-free materials and produced under ISO9001 quality control, these cartridges balance effective filtration with reliable mechanical strength for mobile use.

How do these filters work together to improve my RV water?

The two filters operate in sequence: the 5-micron PP sediment cartridge captures visible particles such as sand, rust and dirt, preventing clogging and abrasion. The 1-micron CTO carbon block with KDF then targets chlorine, unpleasant tastes and certain heavy metals, polishing the water for drinking and cooking. This staged approach extends life of the carbon block and preserves flow rate.

• Stage 1: 5µm polypropylene removes particulates and large debris.
• Stage 2: 1µm CTO carbon block with KDF reduces chlorine, odors, and some metals.
• Combined: Improved clarity, taste and protection for fittings, pumps and appliances.

Will these cartridges fit my existing 10" x 2.5" filter housing?

Yes — both cartridges are manufactured to standard 10" x 2.5" dimensions and are compatible as drop-in replacements for PUREPLUS dual-stage RV housings and most universal 10" x 2.5" systems. They install the same way as typical spin-on or cartridge-style replacements, so no special adapters are needed in most installations.

• Standard sizing: 10 inches by 2.5 inches for universal fit.
• Designed for drop-in replacement in PUREPLUS dual-stage housings.
• Works with most aftermarket 10" x 2.5" filter housings and quick-change systems.

How durable and safe are these PUREPLUS replacement filters?

PUREPLUS manufactures these cartridges under ISO9001 procedures with extensive testing, including pressure and water-hammer assessments, to ensure leak-free and consistent performance. Materials are food-grade and BPA-free; the PP10 sediment filter carries IAPMO R&T material certification to NSF/ANSI 42 standards, indicating safe construction and suitability for potable water systems.

• Manufactured under ISO9001 with 34 production checks.
• Pressure-tested to 400 PSI and subjected to water hammer cycles.
• Food-grade, BPA-free components and certified materials on sediment element.

How should I maintain and replace these cartridges for best performance?

Replace the sediment filter first if it appears clogged or after the recommended service interval — doing so extends the life of the carbon block. Inspect housings and O-rings during each service, flush the system briefly after installing new cartridges, and follow your RV manufacturer’s guidance on replacement frequency based on water quality and usage.

• Check filters visually for discoloration or flow reduction.
• Replace pre-filter first to protect the carbon block.
• Flush new cartridges for a short time before use; inspect O-rings each change.

Who is this for: This PUREPLUS 2-pack is suited to RV owners, boaters and camper van travelers who need dependable, easy-to-install water filtration that improves taste, reduces chlorine and protects plumbing. It’s ideal for people using campground, marina or municipal sources who want an economical, certified replacement set that fits common 10" x 2.5" housings.
