Melt-blown filter

A melt-blown filter cartridge is a type of depth filtration system crafted by thermally bonding melt-blown polypropylene (PP) fibers into a gradient structure. It’s popular in water filtration systems—especially as a first-stage or pre-filter—thanks to its efficiency and versatility.

Key Features:

  • High filtration efficiency: Captures particles as small as 0.1–1 micron, making it ideal for fine sediment removal and RO prefiltration

  • Excellent dirt-holding capacity: Gradient structure allows it to retain a lot of debris before clogging

  • Chemical resistance & purity: Made from 100% polypropylene with no binders or adhesives—resists many chemicals and is FDA-grade safe for food, beverage

  • Durability: Withstands a range of temperatures and pressures, offering a long service life and low replacement costs

  • Low pressure drop: Maintains efficient flow due to uniform pore distribution

  • Various forms: Available as flat, grooved, or embossed cartridges—grooved versions increase surface area and enhance lifespan

Common Applications

  • Water filtration systems: Whole-house pre-filtration, RO systems, drinking water treatment

  • Industrial & commercial use: Including pharmaceuticals, food & beverage, chemicals, electronics, power, and oil & gas sectors

Summary

  • Filtration Type: Depth filtration via melt-blown PP fibers.

  • Efficiency: Excellent—captures very fine particles (down to 0.1–1 µm).

  • Dirt Capacity: High, thanks to gradient layering.

  • Durability & Safety: Robust chemical resistance; no binders; FDA-compliant.

  • Performance: Efficient flow (low pressure drop); suitable across varied industries.

  • Variations: Available in flat, grooved, embossed forms to optimize performance.

  • Ideal For: Pre-filtration in water systems, industrial filtration, and sensitive applications.
