This disc-shaped activated carbon filter cartridge is designed for sports water bottles, filtering tap water to reduce chlorine, odours, organic matter and some heavy metals while retaining beneficial minerals. It is built for outdoor enthusiasts, hikers and travellers who need reliable portable water treatment. The brand is Ranveth, and each cartridge pairs food-grade coconut shell activated carbon with non-woven fabric and an ABS/PP housing to deliver a balance of adsorption efficiency, low airflow resistance and service life.
At the core of this cartridge is food-grade coconut shell activated carbon, selected for its high adsorption capacity and consistent pore structure. The carbon is enclosed by a food-grade non-woven fabric that acts as a pre-filter and post-filter, containing fine particles while allowing water to pass freely. The outer shell is made from ABS or PP, both food-contact-safe thermoplastics that provide structural rigidity without adding significant weight.
This layered construction is not arbitrary. The non-woven fabric upstream of the carbon captures larger suspended solids, protecting the carbon bed from premature clogging. The carbon layer itself is engineered for optimal contact time: water flows through the disc at a rate that allows sufficient interaction with the carbon surface for chlorine reduction, yet the pressure drop remains low enough for gravity-fed or low-pressure bottle systems. Downstream, a second non-woven layer ensures no carbon fines migrate into the drinking water.
The pairing of media directly influences three performance factors. First, efficiency: the coconut shell carbon offers a high surface area, and the non-woven fabric prevents fouling, so the carbon’s capacity is used effectively. Second, airflow resistance (or water flow resistance, in this case): the disc geometry and fabric permeability are matched to maintain an easy flow rate without requiring pumping. Third, service life: by keeping particulates away from the carbon, the fabric extends the useful life of the cartridge to a typical 100–200 L of water, depending on feed water quality and usage frequency. Every material choice is validated in our CNAS-accredited laboratory, where we test for chlorine removal (≥95% in internal testing), flow rate and structural integrity.

This disc cartridge is primarily used in sports water bottles and portable hydration systems. Its low-profile shape fits many bottle caps and filter housings, making it suitable for outdoor, hiking, camping and travel scenarios where access to clean drinking water is limited. The cartridge is also compatible with some water pitchers, desktop water dispensers and coffee machine water tanks, provided the housing dimensions match. Because the media and housing materials are food-grade, the cartridge can be used in applications requiring potable water contact. For OEM projects, we adapt the disc dimensions and carbon formulation to suit the specific bottle or appliance design, ensuring a proper fit and optimal flow characteristics.

Our engineering team will review your inputs and propose a media pairing, layer structure and housing design that balance efficiency, resistance and life. We can also provide samples for validation before mass production.
Ranveth is a filter manufacturer with over 20 years of experience in filtration research and manufacturing, exporting to Europe, the USA, Japan and South Korea. Our self-built laboratory is CNAS-accredited, which means the media choices we make for your cartridge are backed by test reports for filtration efficiency, dust holding capacity and resistance. This is the foundation of our approach: we do not guess at performance; we measure it.
Our production base in Zhongshan, Guangdong, covers 50,000 m², including six cleanrooms totalling 20,000 m². Cartridge assembly and packaging take place in these controlled environments to prevent secondary contamination. We are certified to IATF 16949 (achieved in 2024) and hold ISO 9001, ISO 14001 and ISO 45001 system certifications. Products comply with REACH and RoHS regulations, and we can provide compliance documentation as needed.
With more than 1,000 filtration solutions developed, we support OEM/ODM projects that customise size, structure, media grade, housing material, logo and packaging. Multiple automated production lines give us a monthly capacity of millions of pieces, and our IQC, IPQC and OQC processes ensure consistent quality from incoming materials to final shipment.
To discuss your water bottle filter project, please contact us with the details listed above. Whether you need a standard disc cartridge or a fully customised solution, we will respond with a proposal, sample availability and pricing. For standard configurations, samples are available free of charge (freight collect); custom samples may incur a development fee, which is credited against your bulk order. Let us help you bring a reliable, well-engineered filter to your market.
It uses food-grade coconut shell activated carbon as the core adsorption media, enclosed by food-grade non-woven fabric and housed in an ABS/PP casing. The fabric acts as both pre-filter and post-filter, protecting the carbon bed and preventing fines from escaping. This combination is chosen to balance chlorine reduction, flow rate and service life.
The non-woven fabric upstream captures larger particles, keeping the carbon surface accessible for adsorption, which maintains efficiency. The fabric’s permeability and the disc geometry are matched to allow a low-pressure flow suitable for gravity-fed bottles. Downstream fabric ensures no carbon particles enter the drinking water. This layered design minimises flow resistance while extending the carbon’s useful life.
The standard disc cartridge is rated for 100–200 L of water, which typically corresponds to 1–3 months of use depending on water quality and frequency. For custom formulations, we can adjust the carbon weight and media blend to target a longer or shorter life aligned with your product positioning. We recommend replacing the cartridge when flow rate noticeably decreases or after the stated volume, whichever comes first.
Yes, we offer full OEM/ODM customisation. You can specify the disc diameter and thickness, carbon weight and formulation, housing colour and material, logo printing and packaging format. Our engineering team will work from your drawing or sample to ensure proper fit and performance. Custom tooling may be required for non-standard dimensions.
Yes, we encourage sample testing. Standard samples are provided free of charge, with freight collect. For customised samples, a development fee may apply, which is credited against your bulk order. Our CNAS-accredited lab can also assist with preliminary testing data to support your certification needs.
