I. PP Sediment Filter Cartridge

Key Features:

• Filtration Precision: 5.0 micron nominal rating, effectively traps sediment, rust, suspended solids, colloids, and other large particulate impurities

• Connection Type: Quick-connect (push-in/pull-out fitting) with built-in O-ring seal, tool-free installation, plug-and-play

• Dimensions: Standard 10-inch length, compatible with most universal quick-connect housings

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

Core Advantages:

• Deep gradient pore structure (outer-loose/inner-dense) offers high contaminant-holding capacity and extended service life

• As the first-stage pre-treatment, effectively reduces turbidity and SDI (Silt Density Index), extending RO membrane life by 2–3 times

• Compatible with 75G–600G RO systems with low flow resistance

Product Description:
This product is a 10-inch PP melt-blown quick-connect sediment filter cartridge, designed for the first-stage coarse filtration in water purification systems. The quick-connect fitting (equipped with O-ring seal) requires no wrenches—replacement can be done by hand with reliable leak-proof performance. Effectively removes visible particulates and colloids, reducing the load on downstream RO membranes and carbon filters. An ideal pre-filter combining replacement convenience with filtration economy.

II. Carbon Block Filter Cartridge (CTO)

Key Features:

• Filtration Precision: 5.0 micron nominal rating, dual-function physical filtration and chemical adsorption

• Connection Type: Quick-connect with built-in O-ring seal, tool-free installation

• Dimensions: Standard 10-inch length

• Material: High-quality activated carbon formed through advanced sintering technology with large surface area

Core Advantages:

• Effectively removes chlorine, odor, and volatile organic compounds (VOCs), significantly improving water taste and odor

• Dual-function performance — physical sediment trapping combined with chemical adsorption (chlorine and odor removal) — two functions in one cartridge

• Can be used as either a pre-carbon filter (protecting RO membrane from chlorine damage) or a post-carbon filter (enhancing water taste)

• Compatible with 75G–600G RO systems

Product Description:
This product is a 10-inch CTO quick-connect sintered carbon block filter cartridge, combining physical filtration and chemical adsorption capabilities. The quick-connect fitting allows hand-operated replacement with reliable leak-proof performance. When installed as a pre-filter, it adsorbs chlorine to protect the RO membrane; when installed as a post-filter, it removes residual odors to enhance taste. An ideal carbon block filter choice for quick-install water purification systems.

III. Granular Activated Carbon Filter (GAC / UDF)

Key Features:

• Filtration Precision: 5.0 micron nominal rating

• Connection Type: Korean-type quick-connect with built-in O-ring seal, tool-free installation

• Dimensions: Standard 10-inch length

• Material: High-quality coconut shell granular activated carbon with high iodine value, professionally acid-washed

Core Advantages:

• Abundant micro-pores and large surface area provide high adsorption efficiency for chlorine, color, odor, and organic compounds

• Professionally acid-washed with low ash content, ensures clear effluent with no carbon fines residue

• Can be used as either a pre-UDF (adsorbing chlorine to protect RO membrane) or a post-UDF (enhancing water taste)

• Compatible with 75G–600G RO systems

Product Description:
This product is a 10-inch UDF quick-connect granular activated carbon filter cartridge, filled with high-quality coconut shell granular activated carbon. Professionally acid-washed, it features high iodine value, low ash content, and high adsorption efficiency. The Korean-type quick-connect fitting allows hand-operated replacement with reliable leak-proof performance. Pre-installation adsorbs chlorine to protect the RO membrane; post-installation removes residual odors to improve taste. An ideal activated carbon filter choice for quick-install water purification systems.

IV. Ultrafiltration Membrane Filter (UF)

Key Features:

• Filtration Precision: 0.01 micron (10 nanometers) ultra-high precision

• Connection Type: Quick-connect with built-in O-ring seal, tool-free installation

• Dimensions: Standard 10-inch length

• Material: Hollow fiber ultrafiltration membrane (PVDF/PAN options available)

• Power Source: Operates on tap water pressure, no electricity required

Core Advantages:

• Effectively removes 99.99% of bacteria, viruses, Giardia, Cryptosporidium, and other pathogenic microorganisms

• Retains natural minerals and trace elements in water for healthier drinking water

• Zero power consumption, zero wastewater discharge — energy-efficient and environmentally friendly

• Hollow fiber membrane offers strong anti-fouling properties, backwashable for extended service life

• Compatible with 75G–600G water purification systems

Product Description:
This product is a 10-inch quick-connect hollow fiber ultrafiltration membrane filter cartridge with a filtration precision of 0.01 microns. It effectively removes bacteria, viruses, and other pathogenic microorganisms while retaining beneficial natural minerals and trace elements. The quick-connect fitting allows hand-operated replacement with reliable leak-proof performance. Operates on tap water pressure — no electricity required and no wastewater produced. Compatible with 75G–600G water purification systems, it is an ideal ultrafiltration solution for household, commercial, outdoor, and RV applications.
