Housing Categories

Choose the Right Housing for Your Application

Standard 3G Housings

Compact and efficient filter housings designed for residential use with integrated brackets and pressure release valves. Available in 10-inch and 20-inch configurations with 3/4-inch or 3/8-inch NPT connections, these units feature durable blue or clear sumps for easy filter monitoring and quick cartridge replacement.

Big Blue Systems

High-capacity filter housings built for demanding residential and light commercial applications requiring greater flow rates and longer service intervals. These 20-inch Big Blue housings accommodate larger diameter filter cartridges and feature 1-inch NPT ports for maximum flow, available in both clear sump and blue sump configurations.

Slim Profile Housings

Space-saving filter housings like the Hydronix HF2 Series designed for installations with limited clearance. These compact units accept standard 10-inch by 2.5-inch diameter cartridges while maintaining a minimal footprint, making them ideal for under-sink installations, RV systems, and point-of-use applications where space is at a premium.

Selection Process

How to Select Your Filter Housing

1

Determine Cartridge Size

Identify the filter cartridge length you need based on your water quality requirements and available installation space. Standard residential systems typically use 10-inch cartridges for point-of-use applications, while whole-house systems benefit from 20-inch cartridges that provide longer service life and higher flow capacity.

2

Match Thread Connections

Select the appropriate NPT thread size to match your existing plumbing infrastructure. Common residential applications use 3/4-inch NPT connections, while higher flow applications require 1-inch NPT ports found on Big Blue housings. Ensure your housing thread size matches your inlet and outlet plumbing for proper installation.

3

Choose Sump Material

Decide between clear and opaque sump options based on your monitoring preferences and installation location. Clear sumps allow visual inspection of filter condition and sediment buildup without disassembly, while blue or black sumps protect UV-sensitive applications and provide a professional appearance in visible installations.

Maintenance Tip: Always relieve system pressure using the built-in pressure release button before unscrewing your filter housing sump. Apply food-grade silicone lubricant to the O-ring during each filter change to ensure a proper seal and prevent leaks, and hand-tighten only to avoid cracking the sump or damaging the threads.

Easy Maintenance Access

Tool-free sump removal and integrated mounting brackets simplify filter cartridge replacement and system servicing. Clear sump options provide instant visual confirmation of filter condition, while pressure release valves ensure safe maintenance procedures without specialized tools or plumbing knowledge.

Durable Construction

Heavy-duty reinforced polymer housings resist corrosion, withstand high water pressure, and maintain structural integrity through years of continuous operation. Premium materials ensure long-term reliability in both hot and cold water applications, backed by manufacturer warranties and proven field performance.

Optimized Flow Rates

Engineered inlet and outlet configurations minimize pressure drop while maximizing water flow throughout your home or facility. Multiple port size options accommodate different plumbing systems, ensuring your filtration doesn't compromise water pressure at fixtures and appliances even during peak demand periods.

Universal Compatibility

Industry-standard dimensions ensure compatibility with a wide range of replacement filter cartridges from multiple manufacturers. Whether you need sediment filtration, carbon block, or specialty media cartridges, these housings accept standard 10-inch and 20-inch formats for maximum flexibility in water treatment solutions.
