Description

The 20-inch melt-blown PP filter cartridge is engineered with a multi-layer gradient structure to efficiently remove suspended particles, rust, sediment, and impurities from water. Manufactured from 100% food-grade polypropylene without any chemical binders, it is the ideal, cost-effective pre-filtration solution for reverse osmosis systems, whole-house water filtration, and food & beverage processing. 


Application
Designed for versatile pre-filtration across residential, commercial, and industrial settings:

Residential Water Treatment

l Whole-house sediment filtration to protect household appliances (water heaters, washing machines).

l Pre-filter stage for under-sink RO (Reverse Osmosis) systems and UV sterilizers.

Commercial & Public Facilities

l Pre-filtration for commercial drinking water fountains, office water dispensers, and restaurant beverage equipment.

l Swimming pool and spa water pre-treatment.

Food & Beverage Industry

l Pre-treatment for process water, ingredient water, and wash water in food processing plants, breweries, and bottling lines.

l Protection of downstream micro-filtration and ultra-filtration (UF) membranes.

Light Industrial & Manufacturing

l Pre-filtration for cooling tower makeup water and small-scale industrial circulating water systems.

l Electronics manufacturing pre-RO water treatment, electroplating solution pre-filtration, and general utility water purification.

l Agricultural irrigation systems to prevent emitter clogging.

 

Frequently Asked Questions (FAQ)

Q1: What is the difference between melt-blown filters and string-wound filters?

A: Melt-blown filters use a thermal-bonded gradient polypropylene web structure for high-efficiency particle retention. String-wound filters use twisted yarn patterns, which are typically better suited for high-viscosity liquids.

Q2: What micron rating should I choose for RO pre-filtration?

A: 5 µm or 10 µm PP melt-blown cartridges are the most popular choices for RO system pre-filtration to effectively protect the high-pressure pump and membrane.

Q3: Can this filter cartridge be cleaned and reused?

A: No. This is a disposable depth filter. Attempting to wash or reuse it may damage the gradient structure and compromise filtration performance.

Q4: Is this safe for drinking water?

A: Yes. It is made of 100% food-grade polypropylene with no chemical binders, making it completely safe for potable water and food processing.

Q5: What end cap types are available?

A: Standard configurations include DOE (Double Open End) and SOE (Single Open End with gasket/O-ring options) to fit various filter housings.
