Your Complete Source for Cartridge Filter Solutions
Our product line covers three core technologies — pleated, string wound, and melt blown — so you always have a fit-for-purpose choice.
Whether you need a sediment filter cartridge for pre-treatment, a tight-rating melt blown filter cartridge for fine particle control, or a high-flow pleated filter cartridge for large volume systems, our range has you covered.
Our Products
Our pleated filter elements can accommodate a larger filtration surface area within each filter housing.
When a fluid contains a significant amount of sediment, a wound filter element is the ideal choice, specifically designed for such operating conditions.
Our melt-blown filter cartridges are made from 100% pure polypropylene and contain no binders or glues.
Advantages of Cartridge Filters
You purchase directly from our manufacturing facility. No middlemen, no markups.
We can manufacture filter elements for you based on your exact dimensions, filtration precision, and end cap style.
Every batch of our filter cartridges undergoes integrity testing and dimensional inspection.
For standard in-stock items, your order will be shipped within 3 to 7 days.
Need FDA, NSF, RoHS, or CE certificates? We provide full compliance paperwork for your filter cartridge products so your audit passes without delays.
Our engineering team will evaluate your flow rate, fluid type, and particle characteristics to recommend the product best suited for your system.
How to Pick the Right Filter Cartridge for Your System
The primary factor to consider is filtration precision. A filter element with a precision of 1 micron is capable of capturing extremely fine particles, but it is also more prone to clogging; in contrast, a filter element with a precision range of 10 to 50 microns can handle higher impurity loads and offers a longer service life.

Why Choose Lianda for Filter Elements?
We manufacture a wide variety of filter cartridges within our own facilities—whether pleated, wound, or melt-blown—handling the entire production process independently in-house. You are not purchasing from a trading company. Prior to shipment, every batch of products undergoes rigorous testing to verify both dimensions and performance. We have supplied filter cartridges to water treatment plants, industrial facilities, food manufacturers, and OEM equipment manufacturers in over 30 countries worldwide. Whether you require standard-specification cartridges or customized solutions, our team will work directly with you.
Yes. Our melt blown cartridges are manufactured from 100% virgin polypropylene with no binders or additives, and they comply with FDA 21 CFR standards for food contact applications. Certificates of compliance are available for every batch. If you need NSF/ANSI 61 certification or other specific documentation for your industry, let us know and we can advise on the right product variant.
Certainly. If your system requires non-standard dimensions, specific filtration precision, or specialized filter media, simply let us know your requirements: housing dimensions, fluid type, flow rate, and the particle size you need to capture. Our engineering team will assist you with an OEM custom order; we will provide a tailored solution, so you need not worry about excessive lead times.
Replacement frequency depends on your water quality, flow rate, and application. In clean municipal water systems, a standard polypropylene filter cartridge typically lasts 3–6 months. In high-turbidity or heavily loaded systems, your changeout interval will be shorter. A differential pressure gauge on your housing is the most reliable indicator — replace when the pressure drop reaches the manufacturer’s limit.
