Introduction
For over 16 years, LEFILTER has been a trusted manufacturer of high-performance filter cartridges and filtration systems, specializing in cost-effective alternatives to premium brands such as PALL, Hydac, MAHLE, Internormen, and Parker. Today, the company is making waves in the water treatment industry with its high-efficiency big flow filter cartridges, designed to deliver comparable filtration performance at a fraction of the price, while ensuring fast production and short lead times.
The Growing Demand for Big Flow Filtration in Water Treatment
Municipal water supply, industrial wastewater treatment, and pure water preparation require high-capacity filtration solutions that can efficiently remove suspended solids, sand, rust, bacteria, and other contaminants without compromising flow rates. Traditional filter cartridges often struggle to balance high throughput, long service life, and cost-effectiveness, leading to frequent replacements and increased operational expenses.
LEFILTER’s big flow filter cartridges address these challenges with innovative design and advanced materials, making them ideal for:
1. Municipal Water Supply – Ensuring clean drinking water by filtering sediments, algae, and microorganisms.
2. Industrial Wastewater Treatment – Removing heavy particles, oils, and chemical residues before discharge or reuse.
3. Pure Water Preparation – Serving as pre-filtration for reverse osmosis (RO) systems, protecting membranes from clogging and damage
Key Advantages of LEFILTER’s Big Flow Filter Cartridges
1. High Flow Rate with Reduced Operating Costs
Unlike conventional filters, LEFILTER’s big flow cartridges feature a large filtration area and optimized pleated design, allowing them to process higher volumes of water with lower pressure drop. This means fewer filter changes, lower energy consumption, and reduced maintenance costs.
2. Superior Filtration Efficiency
Made from thermally bonded polypropylene (PP), these cartridges provide 99% filtration efficiency at various micron ratings (1–100μm), effectively capturing fine particles, colloids, and microbial contaminants. The gradient density structure ensures deep filtration, extending service life while maintaining consistent performance.
3. Longer Lifespan & Easy Maintenance
Thanks to their high dirt-holding capacity, LEFILTER’s big flow cartridges last 2–3 times longer than standard PP melt-blown or string-wound filters. Their modular design allows for quick replacement, minimizing downtime in critical water treatment processes.
4. Cost-Effective Alternative to Brand-Name Filters
Many industries rely on expensive imported filters from PALL, Hydac, or Parker. LEFILTER offers direct replacements with identical dimensions and performance but at 30–50% lower prices, making high-efficiency filtration accessible to more businesses.
5. Fast Production & Reliable Delivery
With a vertically integrated manufacturing facility in Xinxiang, Henan, LEFILTER maintains short lead times (7–15 days for standard models) and can customize filters to meet specific flow rate, material, or connection requirements.
