The Thesvin disc-shaped activated carbon filter cartridge is a compact, food-grade water filter designed to drop into sports water bottles and similar portable drinking vessels. It reduces chlorine, odours, organic matter and some heavy metals from tap water, while retaining beneficial minerals. The filter is made for outdoor enthusiasts, hikers, travellers and anyone who wants cleaner-tasting water on the go, and it is manufactured by Thesvin, a filter specialist based in Zhongshan, Guangdong, China.
Fitment is the first consideration with any disc-style cartridge. This filter is shaped as a round disc, and it is intended to sit inside the neck or base of a compatible water bottle, depending on the bottle design. Because the source data does not specify a universal interface, Thesvin works from your bottle's internal dimensions or from a sample of the original filter to match diameter, thickness and sealing behaviour. The outer housing is available in ABS or PP, and the filter media is encapsulated between food-grade non-woven layers, so the disc holds its shape and does not shed carbon fines into the water. The fit is confirmed through samples before production, so the cartridge seats correctly and seals against the bottle without bypass.
The core media is food-grade coconut-shell activated carbon, selected for its adsorption capacity and clean taste profile. As water passes through the disc, the carbon adsorbs residual chlorine, unpleasant tastes and odours, and organic compounds, and it also reduces some heavy metals. Minerals that occur naturally in water are largely retained. Testing at Thesvin's CNAS-accredited laboratory reports chlorine removal of more than 95%. The filter is intended for municipal tap water in outdoor, travel and everyday portable drinking scenarios, and it is not designed to treat microbiologically unsafe water.

Thesvin has held IATF 16949 certification since 2024, and dimensional consistency is controlled through IQC, IPQC and OQC checks from incoming carbon and housing resin through to packed cartridges. The company's own laboratory is CNAS-accredited and can issue test reports on filtration efficiency, dust holding capacity and resistance, which supports your market-entry documentation. Production runs in a 50,000 m² facility that includes six clean rooms totalling 20,000 m², and the site operates under ISO 9001, ISO 14001 and ISO 45001. Products comply with REACH and RoHS, and compliance files can be supplied on request. With more than 20 years of export experience to Europe, the US, Japan and Korea, Thesvin ships standard samples in 7–15 days and OEM production orders in 25–35 days.
To get a quotation and sample plan, send us the device or bottle model, the disc size or a drawing, the required flow or daily water volume, operating conditions, and your target quantity. If you do not have a drawing, an old filter is enough for us to work from. Contact our team via the contact page and we will respond with the next steps.
Fitment depends on the internal diameter and depth of your bottle's filter seat. Thesvin matches the disc to your drawing or to an original filter sample, and we confirm fit with a physical sample before production. Send us the bottle model or dimensions and we will advise.
Yes. An original filter is often the fastest way to match the interface. We measure diameter, thickness and sealing surfaces from the sample and produce a drawing for your approval before tooling or production.
The coconut-shell activated carbon removes more than 95% of residual chlorine, as tested in Thesvin's CNAS-accredited laboratory. It also reduces odours, organic matter and some heavy metals while retaining beneficial minerals. It is not intended for microbiologically unsafe water.
Yes. Thesvin offers OEM/ODM customisation of diameter and thickness, carbon weight and formulation, housing colour and material, logo printing and retail packaging. Custom work starts from your target filter life and bottle interface.
MOQ is typically 1,000–2,000 pieces for standard specifications, while custom models are recommended from 5,000 pieces. Standard samples ship in 7–15 days and OEM production orders in 25–35 days.
The standard disc is rated for 100–200 L, or roughly 1–3 months depending on water quality and daily use. For higher daily volumes, we can adjust the carbon weight to extend filter life.
Yes. Standard samples are free with freight collected, and custom samples carry a development fee that is credited against a bulk order. Our CNAS lab can also support pre-testing for your certification needs.
Thesvin has exported to Europe, the US, Japan and Korea for more than 20 years, and holds ISO 9001, ISO 14001, ISO 45001 and IATF 16949 certifications. We can prepare REACH and RoHS compliance documents for your market. Contact us with your requirements to start an inquiry.
