Our disc-shaped activated carbon filter cartridge utilizes high-quality food-grade coconut shell activated carbon as the core filtration medium, combined with food-grade non-woven fabric and ABS/PP shell structure. It effectively adsorbs residual chlorine, odors, organic substances, and some heavy metals from tap water, significantly improving the taste while retaining beneficial minerals. According to tests conducted by our CNAS accredited testing center, the residual chlorine removal rate can reach over 95%, making it fully suitable for portable drinking scenarios such as outdoor sports, hiking, and traveling.

The standard disc-shaped activated carbon filter cartridge generally has an effective filtration capacity of 100–200L (approximately 1–3 months of use, depending on water quality and usage frequency). We can customize different weights of activated carbon formulas and filtration capacities based on the customer's bottle capacity, target market water quality, and product positioning to ensure product performance perfectly matches the end-use scenarios.

Yes. As a professional filtration manufacturer established in 2002, we have obtained ISO 9001, ISO 14001, and ISO 45001 certification, as well as international certifications such as NSF, EPA, European BSC1, and SOP. In 2024, we also acquired IATF16949 and medical GMP certifications. The activated carbon used in the filter cartridge and components in contact with water comply with food safety standards, making it safe for export to high-end markets in Europe, America, Japan, and South Korea.

We offer a complete OEM/ODM service. Customizable content includes: filter cartridge size (diameter/thickness), activated carbon weight and formula, shell color and material, printed logo, independent packaging design (color box/vacuum bag/blister, etc.), and supporting manuals and certification marks. Leveraging over 20 years of industry experience and thousands of filtration solutions, our engineering team can provide samples and complete technical proposals within 2-3 weeks.

Our factory covers an area of 50,000㎡, with 6 clean workshops totaling 20,000㎡. The assembly and packaging of the filter cartridges are completed in a clean environment to avoid secondary contamination. The company has a national CNAS accredited testing center that can conduct full-process testing on raw materials, semi-finished products, and finished products, including key indicators such as flow rate, residual chlorine removal rate, microbiology, and heavy metal leaching. Each batch of products has a complete QC report to ensure stable and traceable quality.

The MOQ is usually 1,000-2,000 pieces, depending on product specifications and packaging requirements; the recommended MOQ for customized models is 5,000 pieces. In terms of delivery time, standard items in stock can be shipped within 7-15 days; the mass production delivery time for OEM custom orders is generally 25-35 days. We have our own factory in Zhongshan, Guangdong, with flexible production scheduling, and we can arrange VMI inventory or staggered deliveries for long-term partners to ensure your supply chain stability.

Yes. We highly welcome customers to conduct sample testing before bulk orders. Standard samples can be provided free of charge (shipping costs covered by the customer); for customized samples, a certain sample fee will be charged based on the complexity of development, which can be offset upon bulk ordering. Our CNAS laboratory can also assist customers in obtaining necessary preliminary testing data for third-party certification, helping them to quickly enter the target market.

Our products have been exported to many countries and regions, including Europe, the United States, Japan, and South Korea, and we have long-term relationships with renowned brand merchants, chain retailers, and OEM customers. We are familiar with the regulatory requirements of different countries/regions (such as US NSF/EPA, EU REACH/BSC1, etc.) and can assist customers in completing compliance plans based on the target market, making us a reliable manufacturing partner for entering international markets.
