Plunge Crafters Cold Plunge Water Filter System — 10" Housing with 2×50μm Pleated Cartridges, 3/4" NPT Ports & Mounting Kit

The Plunge Crafters Cold Plunge Water Filter System is a 10" inline sediment filtration kit with dual 50-micron pleated filters, mounting hardware, and wrench—built to keep ice baths, spas, pools, or whole-house lines free of visible dirt and rust.

Designed for cold plunge tubs and other recreational water systems, this compact filter housing and two pleated elements trap sand, rust, and suspended particles so water looks and feels cleaner. The kit ships with a sturdy 10" housing equipped with 3/4" NPT ports, hose barb adapters for low-pressure installations, a mounting bracket with screws, and a wrench for quick cartridge changes. A digital build guide is included to help you assemble the system and integrate optional ozone venturi sanitation (venturi sold separately).

How does this filter improve the clarity of my cold plunge?

The dual pleated 50-micron cartridges remove suspended solids that cause cloudiness and visible debris in plunge and spa water. Pleated media provides a large surface area, capturing particles while maintaining flow for circulation systems.

• Two 50-micron pleated elements trap rust, sand, and dirt.
• 10" housing fits standard replaceable cartridges for easy maintenance.
• Pleated design extends service life versus spun-wound filters.
• Recommended monthly replacement with daily use to preserve performance.

Can I install it on a whole-house line, pool, or spa?

The housing supports city and well water but is primarily tuned for point-of-use cold plunge, spa, or low-pressure pool lines when used with the included hose barbs. For whole-house high-pressure installations, use proper threaded plumbing fittings and verify pressure ratings rather than relying on hose barb connections.

• 3/4" NPT ports for threaded plumbing connections (OD 26.7mm, ID 23.7mm).
• Two 3/4" hose barb fittings included for low-pressure setups only.
• Use threaded fittings or consult a plumber for high-pressure whole-house use.
• Clamps and mounting kit secure the housing for permanent installations.

What’s included and how easy is maintenance?

The kit comes complete with the filter housing, two pleated cartridges, mounting bracket, screws, and a housing wrench. Cartridge swaps are straightforward: depressurize the line, open the housing with the wrench, remove the old cartridge, insert the replacement, and reseal; most users replace filters monthly with frequent use.

• Complete hardware: housing, 2× pleated filters, bracket, screws, wrench.
• Digital step-by-step assembly guide included for DIY installation.
• Routine maintenance: depressurize, unscrew housing, swap cartridges, reseal.
• Optional ozone venturi can be added for advanced sanitation (sold separately).

Will this affect water flow or pressure in my system?

The dual 50-micron pleated cartridges are designed to balance filtration with flow, giving good clarity without severe pressure drop in low- to moderate-flow applications. High-flow whole-house or pressurized systems may notice reduced pressure if cartridges load with sediment—monitor and replace as needed.

• Pleated filters preserve flow better than dense spun filters.
• Monitor differential pressure; replace cartridges when flow decreases.
• For high-pressure systems, choose proper fittings and check specifications.

Who is this for: Plunge Crafters’ Cold Plunge Water Filter System is ideal for owners of home cold plunge tubs, ice-bath enthusiasts, spa and small-pool operators, or DIY installers who want a compact, serviceable sediment filter. It suits people seeking clearer water from city or well sources, those adding a mechanical pre-filter before chemical or ozone sanitation, and anyone who prefers easy cartridge swaps and a complete mounting kit for tidy installation.
