The Thesvin disc-shaped water dispenser filter is a drop-in cartridge that reduces TDS and chlorine in pet water fountains and smart water dispensers. It combines high-density PET non-woven fabric, ion-exchange resin, and coconut-shell activated carbon to capture hair and debris, soften hard water, and improve taste. It is designed for pet water fountain OEMs, brand owners, and aftermarket suppliers who need a reliable, custom-fit filter.
The filter is built as a flat disc, a format chosen because it seats directly into the shallow filter well of most pet fountains and smart dispensers. The outer diameter, thickness, and edge profile are matched to the host device or duct, so the disc locates without wobble and seals against the housing wall. This keeps unfiltered water from bypassing the media and ensures that flow passes through the entire filter cross-section.
Because every fountain has its own internal geometry, Thesvin does not rely on a one-size-fits-all approach. We work from your existing filter sample, a 3D model, or a simple dimensioned drawing to confirm the disc diameter, thickness, and any locating features such as tabs or recesses. The frame and dimensions are then matched to the host device, so the replacement filter drops in and seats the same way as the original. For OEM projects, we can also adjust the media composition and disc thickness to balance filtration performance with the space available in the fountain.
Water in pet fountains picks up hair, dust, and food particles before it reaches the pump. The outer PET non-woven layer of this disc filter intercepts these larger contaminants, protecting the media inside and keeping the water visually clean. Inside, coconut-shell activated carbon adsorbs residual chlorine and odours that affect palatability, while ion-exchange resin targets calcium and magnesium ions to soften hard water and reduce TDS. The result is water that pets are more likely to drink, which supports hydration.
The filter is intended for cat and dog automatic water fountains, smart constant-temperature water dispensers, and other pet water purification devices. It is not a standalone water treatment system; it is a consumable designed to be replaced every 2 to 4 weeks, depending on local water hardness and how often pets drink. For OEM customers, Thesvin can adjust the ratio of ion-exchange resin to activated carbon to emphasise TDS reduction, chlorine removal, or a balance of both.

Thesvin operates under IATF 16949 (certified in 2024) and ISO 9001, ISO 14001, and ISO 45001 management systems. For this filter, dimensional consistency is controlled through IQC, IPQC, and OQC at each stage: incoming materials are inspected, in-process discs are checked for dimensions and media fill, and finished goods are verified before packing. Our CNAS-accredited laboratory supports testing of filtration efficiency, dust holding capacity, and resistance, and can provide reports for customer verification.
Production takes place in a 50,000 m² facility that includes 20,000 m² of clean workshops across six rooms, where filters are assembled and packed to avoid secondary contamination. Products comply with REACH and RoHS requirements, and compliance documents are available on request. With more than 20 years of filtration experience and exports to Europe, the US, Japan, and South Korea, we support OEM/ODM projects with custom sizes, structures, media grades, logos, and packaging. Multiple automated lines provide monthly capacity in the millions of pieces.

The Thesvin disc filter is designed to match the host device's filter well. We confirm fitment by checking the outer diameter, thickness, and any locating features against your existing filter or a dimensioned drawing. For standard fountains, many sizes are available; for custom models, we can adjust the disc geometry to ensure a proper seal and drop-in replacement.
Yes. You can send us a used filter or a sample of the current part, and our engineers will measure it and propose a matching disc. We can also work from a 3D model or a simple sketch with key dimensions. This is often the fastest way to confirm fitment for OEM projects.
The ion-exchange resin in this filter reduces TDS by targeting calcium and magnesium ions. Actual efficiency depends on water hardness, flow rate, and contact time; in typical fountain conditions, TDS reduction can range from 60% to 90%. For project-specific performance, we can provide test data from our CNAS-accredited laboratory.
Under normal use, we recommend replacing the filter every 2 to 4 weeks, depending on local water hardness, the number of pets, and how often they drink. Regular replacement maintains flow and filtration performance. For OEM customers, we can adjust the media to optimise service life for specific markets.
Yes, we support OEM/ODM customisation. We can adjust the disc size, thickness, and locating features, as well as the ratio of ion-exchange resin to activated carbon to emphasise TDS reduction or chlorine removal. Logo printing and retail packaging options are also available. Our team can develop samples within 2–4 weeks.
For standard specifications, the MOQ is typically 5,000–10,000 pieces, with lead time of 15–25 days. Custom orders generally start at 10,000 pieces and take 30–45 days including tooling and sample approval. We have monthly capacity in the millions of pieces to support large volumes.
Yes, we welcome sample requests. Standard samples are usually shipped within 3–5 business days; custom samples take 2–4 weeks depending on complexity. Each sample is accompanied by technical specifications and, where applicable, test reports from our CNAS-accredited laboratory.
The filter is produced under ISO 9001, ISO 14001, ISO 45001, and IATF 16949 systems. The materials meet US EPA and NSF standards for food-grade safety, and we can provide REACH and RoHS compliance documents. These certifications support market entry and customer confidence.
