Key Features:

• Filtration Precision: 5.0 micron nominal rating, effectively traps sediment, rust, suspended solids, colloids, and other large particulate impurities, protecting downstream RO membranes and activated carbon elements.

• Connection Type: Quick-connect (push-in/pull-out fitting) with built-in O-ring seal. Tool-free installation—plug and play—for convenient, leak-proof replacement.

• Dimensions: Standard 10-inch length, compatible with most universal quick-connect filter housings and water purifier heads.

• Applications: Undersink household use, commercial drinking water systems, outdoor water purification, RVs, and more.

• Material: Food-grade polypropylene (PP), manufactured using a melt-blown process to create a deep gradient filtration structure.

• Flow Rate Compatibility: Designed as a pre-filter for RO systems ranging from 75G to 600G; low flow resistance ensures adequate feed water supply to meet the demands of corresponding RO membranes.

Advantages:

• Quick-Change Design: Compared to traditional threaded twist-in cartridges, the quick-connect structure reduces replacement time to just seconds. Users can perform changes independently, reducing after-sales service costs.

• High Filtration Efficiency: The deep gradient pore structure (outer-loose/inner-dense configuration) offers high contaminant-holding capacity and extended service life.

• Strong Versatility: Standardized quick-connect port sizes (commonly 1/4" or 3/8" push-fit specifications) ensure compatibility with mainstream quick-install water purification systems.

• Pre-Filter Protection: As the first-stage pretreatment, it effectively reduces turbidity and SDI (Silt Density Index), extending RO membrane life by 2–3 times.

• Private mold customization supported; 1-year warranty + free spare parts.

Product Description:

This product is a 10-inch PP melt-blown quick-connect sediment filter cartridge with a 5-micron filtration rating. Manufactured from food-grade PP material using deep gradient melt-blown technology, it serves as the primary coarse filtration stage in water purification systems. The quick-connect fitting (equipped with an O-ring seal) requires no wrenches—replacements can be done by hand with reliable leak-proof performance. This cartridge is compatible with all mainstream 75G–600G RO reverse osmosis systems currently on the market as a pre-treatment stage. By removing visible particulates and colloids from feed water, it effectively lowers turbidity and SDI values, significantly reducing the load on downstream RO membranes and carbon filters, thereby extending the service life of core consumables. As an ideal pre-filter for quick-install water purification systems, it combines replacement convenience with filtration economy.
