What is a Depth Filter Cartridge?
The depth filter cartridge utilizes micron-sized fibers to form a full path of filtration from the surface to the inside, with a “gradient pore size” intelligent filtration unit. The depth retention mechanism extends the life of a single cartridge, eliminating the need for frequent replacements in the production line, and directly increasing production yield by 15%. Optimized fiber bonding technology ensures no leakage under ultra-high differential pressure, bringing you more robust fluid safety. Simplified filtration system, no need to configure redundant multi-stage filtration tanks, a significant reduction in pumping energy consumption, to protect your power system from premature destruction due to high-pressure loads, and extend the service life of the equipment by more than 20%. The high retention accuracy brings you perfect protection for downstream precision components (e.g. ultrafiltration membranes, nozzles) and reduces the replacement cost of downstream equipment by 30%. Even under severe conditions, the deep filter cartridge provides you with an extremely high throughput per pass, ensuring that your production rate is not disturbed by fluctuations in fluid impurities and that your output efficiency is increased by about 10%.

Key Features of Depth Filter Cartridges
FiltEdge depth filter has excellent chemical compatibility, superior structural stability, extremely high dirt-holding capacity and long life, and low-pressure drop operation.
FiltEdge is naturally chemically inert, regardless of strong acids, bases, alcohols or organic solvents, FiltEdge can maintain stable physical and chemical properties, can withstand pH1-14 fluids, and will not release any extracts that may affect the quality of the fluid.
FiltEdge Depth Filter Cartridge adopts an outer protective structure, and precise heat stabilization treatment ensures that the bonding points between microfibers are extremely strong, and the retention efficiency of FiltEdge Cartridge fluctuates less than 0.5% under a continuous pressure difference of 0.3 MPa (43.5 PSID), and the structural displacement is close to zero.
Optimized fiber stack density, with higher effective void volume, internal locking of a large number of solid impurities, colloids and soft particles.
At standard flow rates, the FiltEdge Initial ΔP is 15% – 20% lower than the competition, resulting in a smoother pressure rise over the life of the cartridge.
FiltEdge Coreless Self-Supporting Technology
When traditional cartridges are pressurized, the fibers are pressed against the inner core, resulting in a smaller pore size or even blockage. Inherent structural rigidity to bring true deep filtration, coreless self-supporting process through a simple stack of fibers, loose structure, must rely on the center of the skeleton to prevent deformation under pressure, high temperature thermal gradient self-adhesive technology in the instant of fusion spraying, ultra-fine fibers in the semi-molten state of high-speed spraying, through the precise frequency of the winding, so that the fibers at the intersection of the molecular level of “fusion. “Fusion. Experiments have shown that during the pressure surge from 0.05 MPa to 0.25 MPa, the downstream particle escape rate of the FiltEdge cartridge is close to 0%, while the penetration rate of ordinary cartridges tends to surge by 15%. With the plastic core removed, the cartridge is 100% composed of high-performance polypropylene, a process that creates a sophisticated and robust three-dimensional spatial truss structure inside the cartridge. The self-supporting structure maintains a porosity of 85-90%, resulting in a shorter, barrier-free path for fluid flow, no pore size compression at 0.3 MPa differential pressure, a 15% increase in filtration throughput efficiency, and the elimination of secondary contamination due to leaching of the core material.

Testimonials
Previously plagued by high-priced OEM contracts, we didn’t hesitate to switch to FiltEdge, which offered equal or better filtration at a more competitive price, and found that we were able to reduce replacement frequency by 25% and consumable expenditures by 40% right away. The longer life has saved us over $20,000 per year in labor and consumable costs, truly delivering on the promise of ‘lower cost, higher output.
Michael ROperations Manager | Global Water Solutions, IncMembrane contamination in desalination is the biggest headache, always looking for a cartridge with a high turbidity feed and no bypass leakage, FiltEdge has been very satisfactory, the life of the RO membranes is a doubled longer after use.
Sarah JPrincipal Process Engineer | Advanced Desalination PlantOur high-precision chemical coating line is perfectly compatible with all of our canisters using FiltEdge depth filtration cartridges, with no modifications required and a 5% increase in end-cap yields.
David LDirector of Quality Assurance | Precision Chemical Manufacturing
Absolutely. FiltEdge cartridges are 100% compatible with all major brands of canisters using globally standardized specifications (such as DOE double or 222/226 ports), with the same flow rate as the original, and our gradient density technology provides even longer life.
No, because we utilize a 100% pure polypropylene hot-melt bonding process without the use of any chemical adhesives, resins or surfactants. All materials are FDA 21 CFR compliant with zero fiber shedding and zero chemical extracts in the manufacturing process.
Replacement is scientifically based on pressure differential and is typically recommended when the differential pressure reaches 0.2 MPa (30 PSID). Although FiltEdge cartridges are constructed to withstand up to 0.45 MPa, the cartridge is nearing saturation at this point. Benefits: Timely replacement gives you downstream process stability and prevents pump energy spikes due to excessive differential pressure, saving you 10% on system operating costs.
