Description
The Myteck “Nice Big Fat” 20-Inch Jumbo UF Membrane is the ultimate solution for high-capacity whole-house water purification. With double the surface area and flow rate of the 10-inch jumbo model, this cartridge is designed to handle the most demanding residential or light commercial water requirements. Featuring a 0.01-micron filtration rating and advanced washable PVDF technology, it provides a robust physical barrier that removes 99% of bacteria and viruses, transforming your incoming supply into directly drinkable, safe water.
Features
- Maximum Flow & Surface Area: Optimized for 20″ x 4.5″ (Big Blue) housings to ensure high-volume water delivery with minimal pressure loss.
- Premium PVDF Construction: Built with industrial-grade PVDF hollow fibers that are corrosion-resistant and engineered for durability.
- Washable & Reusable: This membrane can be periodically cleaned/backwashed to restore flow, offering a highly cost-effective alternative to frequent cartridge replacements.
- Superior Purification: Industry-leading 0.01-micron accuracy removes pathogens, ultra-fine silt, and microplastics while retaining healthy natural minerals.
- Universal High-Flow Fit: Fits all standard 20-inch Big Blue/Jumbo housings, making it the perfect upgrade for whole-house systems.
What Does It Do?

Maintenance & Installation
To protect your investment and ensure the longest possible service life:
- Mandatory Chlorine Management: This membrane cannot remove chlorine. It must be paired with a Carbon (CTO or GAC) filter to protect the membrane fibers and improve taste.
- Essential Pre-Filtration: A 5-micron PP sediment filter should be installed upstream to prevent large debris from prematurely clogging the fine membrane pores.
- Washing/Cleaning: Periodically wash or backflush the unit (following manufacturer guidelines) to restore flow rate and clear accumulated “filter cake.”
- Replacement: While washable, we recommend replacement every 12 to 36 months depending on water quality and maintenance consistency.
