External RV Dual Water Filter System for RVs Boats Motor Homes - Dual

In this review of the External RV Dual Water Filter System the bottom line is simple: this is a practical, hard-wearing dual-stage filter aimed at RV and boat owners who want noticeably cleaner water from standard garden hose hookups. The reviewer found the unit easy to mount and connect, and the combination of a 5 micron pre-filter plus a 0.5 micron carbon block noticeably improves taste and removes grit. It is best for users who need an external, mountable freshwater solution rather than an internal plumbing overhaul.

Key Features

• Dual-stage filtration: Two filters work together so larger particles are trapped first and the 0.5 micron carbon block then reduces finer sediment and improves taste.
• Universal hose compatibility: The unit attaches to standard 3/4' garden hose fittings so it connects quickly to common campground and marina water sources.
• Sturdy construction: Thick plastic housings and brass fixtures provide a heavy-duty feel that stands up to regular outdoor use.
• Mountable bracket included: A sturdy mounting bracket lets you fix the canisters to an RV or boat hull for a secure, tidy installation.
• Tool included: The supplied wrench makes tightening and replacing the canisters simple, reducing the chance of cross-threading during service.
• Complete kit: Comes with two canisters, one 5 micron and one 0.5 micron filter, the bracket and wrench so you have everything for initial setup.

Who It's For

This system is ideal for RVers, boaters, and motor home owners who rely on shore water connections and want to remove sand, grit and chlorine taste without modifying internal plumbing. Its external mounting and hose-thread fittings suit temporary or seasonal use where portability and quick hookup matter.

It is less appropriate for buyers seeking whole-vehicle built-in filtration or those who need certified contaminant removal beyond sediment and chlorine taste. Also, if a fully leak-proof, stainless plumbing solution is required, consider higher-end hard-plumbed systems.

Pros & Cons

Pros

• Effective combination of 5 micron and 0.5 micron filters that improves water taste and removes visible grit.
• Easy to install with standard 3/4' hose fittings and a mounting bracket for tidy, secure placement.
• Durable materials with thick plastic housings and brass fittings that feel robust for outdoor use.
• Good value as a complete kit including filters, bracket and wrench for initial setup.

Cons

• Some users report occasional leakage around housings or seals, so careful installation and periodic seal checks are necessary.
• Not a substitute for certified contaminant removal systems if you need reduction of specific chemical contaminants beyond taste and sediment.
