As a core consumable in water treatment and liquid filtration systems, the Damai Melt-blown polypropylene filter cartridge is manufactured using internationally advanced gradient melt-blown technology. Crafted from 100% food-grade polypropylene, the cartridge features a three-dimensional labyrinth-style filtration structure formed through high-temperature melting and ultra-fine fiber layering. With exceptional contaminant retention capabilities and stable physical properties, the melt-blown polypropylene filter cartridge serves as an indispensable filtration barrier for industrial pretreatment, household water purification, medical/pharmaceutical systems, and beyond.
Core Advantages of Melt-blown Polypropylene Filter Cartridge
Gradient Precision Filtration:
Density-graded fibers (5μm-20μm options) create progressive depth filtration, efficiently trapping suspended solids, sediment, rust, colloids, and other pollutants. It’s 40% higher dirt-holding capacity extends service life while preventing surface clogging.
Robust Environmental Adaptability:
ISO 9001-certified quality management system ensures stable performance across 4°C to 80°C water temperatures and 0.3MPa working pressure. Resists structural degradation in high-temperature, acidic, or alkaline environments with zero fiber shedding, compliant with FDA food-contact material standards.
Eco-Conscious Design
Seamless monolithic structure eliminates secondary contamination. Environmentally safe disposal via incineration leaves no residue.
Comprehensive Application Scenarios
• Household Water Purification: Pre-filtration for RO systems to protect membrane longevity
• Industrial Pretreatment: Electronics ultrapure water preparation, plating solution filtration, cooling tower particulate control
• Food & Beverage: Raw water clarification, terminal precision filtration for bottling lines
• Medical Applications: Pharmaceutical particle removal, lab ultrapure water system primary protection

OEM/ODM services for filter cartridges are available, including custom branding, individual packaging, and third-party test reports. Damai delivers full lifecycle filtration solutions for your equipment.
Note that these cartridges are only meant to sieve out dirt and debris – basically, insoluble substances that may make their way into your home’s water outlets. They will, however, not get rid of harsh chemicals, gases, or heavy metals. Neither will they improve the taste nor neutralize any pungent smells.
Additionally, understand that these cartridges are replaceable. As time goes by, melt-blown polypropylene filter cartridges will hold on to enough dirt. To avoid incidents where they do not effectively remove debris or may release some of the previously trapped dirt, switching the cartridge regularly is of the utmost importance.
More often than not, manufacturers recommend performing replacements twice a year or as often as needed.
