blu technology RV water filter replacement Trio 2.5 x 5 in — 3-pack 0.2µm high-flow, carbon & sediment cartridges

Three replacement cartridges that restore your GoBluTech R3 or AR3 2.5" x 5" system to 0.2 micron high-flow filtration, granular activated carbon taste improvement, and sediment pre-filtration for up to 3–4 months of use.

Replaceable cartridges are essential for RV owners who want dependable, better-tasting water on the road. The GoBluTech Trio recharge pack combines a fine 0.2 micron high-flow membrane, a granular activated carbon stage labeled “Tasty,” and a sediment pre-filter called “Longevity.” Together they protect your plumbing, reduce common tastes and odors, and remove rust, sand, and silt—while fitting standard 2.5" x 5" housings used in many RV, tiny home, and van installations.

How does the Trio keep campground water safe enough for everyday use?

The three-stage arrangement targets different contaminants so each stage does the job it’s best at. The sediment pre-filter catches larger debris first, the granular activated carbon reduces chlorine and unpleasant flavors, and the 0.2 micron element removes fine particulates that can affect clarity and equipment.

• Sediment "Longevity" removes rust, sand, and silt to protect downstream stages and fixtures.
• Granular activated carbon lowers chlorine, odors, and off-tastes for drinking and cooking.
• 0.2 micron high-flow element captures very small particulates while preserving strong water pressure.

Will these cartridges fit my R3 or AR3 system and other setups?

Yes—each cartridge is sized for the standard 2.5" x 5" form factor used by GoBluTech R3 and AR3 housings. They’re also easy to adapt into many under-sink, tiny house, or RV inline installations that accept the same cartridge dimensions.

• Compatible with GoBluTech R3 and AR3 filter housings out of the box.
• Works with other systems that accept 2.5" x 5" replacement cartridges.
• Simple swap-in installation—no special tools required beyond your housing wrench.

How long will each set last, and what affects that lifespan?

Typical lifespan for the Trio is about 3–4 months under normal RV usage and typical campground water conditions. Heavy sediment, very high chlorine, or continuous use will shorten life, while low-flow or filtered hookup can extend cartridge longevity.

• Average life: 3–4 months depending on water quality and usage.
• Replace sooner if you notice reduced flow, discoloration, or off-taste returning.
• Pre-flush and regular tank maintenance help maximize cartridge life.

How easy is maintenance and replacement on the road?

Maintenance is straightforward—shut off your water supply, open the filter housing, swap cartridges, and reassemble. No specialized tools or professional service are required, making replacements convenient during seasonal travel or at remote campsites.

• Quick cartridge swaps typically take under 10 minutes.
• Clear instructions included with GoBluTech housings; works with standard 2.5" x 5" systems.
• Lightweight pack is simple to store in an RV or van utility closet.
