Features & Benefit
1.Compact Design with Broad Compatibility
JOZZON residential membrane elements (standard sizes such as 1812, 2012) feature a compact footprint, allowing easy integration into under-sink, countertop, and wall-mounted water purifiers. They are compatible with mainstream filter housings and fittings, simplifying system design and replacement.
2.Safe & Hygienic – Compliant with Drinking Water Standards
Manufactured with food-grade materials and free from BPA or other harmful substances, JOZZON membranes ensure no secondary contamination of the treated water. All products meet strict national drinking water hygiene regulations.
3.Fouling Resistance & Easy Cleanability
The optimized membrane surface charge and enhanced hydrophilicity provide good fouling resistance. Regular flushing or soaking cleaning can effectively restore water flux, extending service life and reducing replacement frequency for end users.
4.Stable Salt Rejection for Pure, Great-Tasting Water
JOZZON residential membranes consistently achieve 95%-98% salt rejection, effectively removing residual chlorine, odors, TDS, and heavy metals. The result is clean, refreshing drinking water with excellent taste.
5.Low Wastewater Ratio – Water Efficient
Through optimized membrane sheet and feed spacer design, JOZZON membranes achieve a low wastewater ratio (e.g., 1:1 to 1:3) while maintaining high water quality, conserving water resources and supporting eco-friendly household use.
6.Quiet Operation & Pump-Free Options
Select ultra-low pressure models operate reliably under low or no pump pressure, minimizing noise from booster pumps. These models are ideal for noise-sensitive home environments and for households with low incoming water pressure.
