The Thesvin pet water dispenser filter cartridge is a drop-in filtration component for cat and dog automatic water fountains and smart circulating water dispensers. It combines high-density PET non-woven fabric, ion-exchange resin and coconut-shell activated carbon to capture hair and floating debris, reduce residual chlorine and odours, and soften hard water. It is designed for pet-product brands, OEM/ODM buyers and distributors who need a reliable, customisable filter that fits their existing dispenser models.
Fitment is the first thing to confirm. This cartridge is made to sit inside the filter slot of automatic pet water fountains, smart constant-temperature circulating dispensers and other pet water-purification devices. The outer dimensions, inlet and outlet openings, and locating features are matched to the host device so the cartridge seats correctly and stays in place while water flows through.
Thesvin supports non-standard customisation based on your existing mould shape, size and filter-media ratio. That means if you have a current filter or a 3D drawing, the sealing face, frame outline and connection points can be adjusted to match your dispenser without changing the housing. The goal is a cartridge that installs the same way as the original part and maintains a consistent seal throughout the replacement cycle.
Water passes through three functional layers. The high-density PET non-woven fabric first intercepts pet hair, dust and visible particles, keeping them out of the inner media. The ion-exchange resin then reduces water hardness by exchanging hardness ions, which helps limit scale build-up in the pump and fountain. The coconut-shell activated carbon adsorbs residual chlorine, odours and organic compounds, improving the taste and smell of the water your pet drinks.
This layered structure is aimed at everyday fountain maintenance: fewer hair clogs, less odour, and softer water that is gentler on the dispenser's internal parts. The cartridge is intended for continuous use in circulating systems where water is repeatedly filtered.

Thesvin operates under IATF 16949 (obtained in 2024) and ISO 9001, ISO 14001 and ISO 45001 systems. Dimensional consistency is controlled through IQC, IPQC and OQC: incoming materials are checked before production, in-process dimensions and assembly are monitored, and outgoing cartridges are inspected against the approved specification. This flow is important for a part that must drop into a customer's existing dispenser without rework.
Our CNAS-accredited laboratory can issue test reports for filtration efficiency, dust holding capacity and resistance, and our 50,000 m² production site includes six clean workshops totalling 20,000 m². Products comply with REACH and RoHS requirements, and compliance documents can be provided. With more than 20 years of filtration manufacturing and export experience to Europe, the US, Japan and South Korea, we support OEM/ODM projects covering size, structure, media grade, frame material, logo and packaging, and have developed more than 1,000 filtration solutions.
To get a quotation, send us the device or vehicle model, a size drawing or the old part, the required airflow or water flow, operating conditions (water quality, temperature, continuous or intermittent use), and your target quantity. With those details we can confirm fitment and propose the right media configuration. Contact our team to start the evaluation.
It is designed to fit automatic pet water fountains and smart circulating dispensers, but fitment depends on the specific model. Send us the dispenser model, a photo of the current filter or a sample of the old part, and we will check the outline, inlet/outlet positions and sealing surfaces against your device. Custom sizes and structures are available through OEM/ODM.
Yes. An old filter is often the fastest way to confirm fitment because it shows the exact shape, interface and wear pattern. We measure it and use it as the baseline for a custom cartridge. If you have a 3D drawing, we can review that as well and flag tolerance points that affect installation.
The cartridge uses coconut-shell activated carbon with ion-exchange resin and achieves a residual chlorine removal rate of over 95%. Under normal use (about 500–1,000 ml of water per day), a single cartridge lasts about 2–4 weeks, depending on local water quality and how often your pet drinks. All performance parameters are verified in our CNAS-accredited testing centre.
The cartridge is made from food-grade materials selected for pet drinking safety. Production follows ISO 9001, ISO 14001 and ISO 45001 systems, and the materials meet US EPA and NSF standards. Compliance documents for REACH and RoHS can be provided for your market assessment.
Yes. We support OEM/ODM customisation of size and outer structure to fit different dispenser brands, filter-media ratio (for example, stronger chlorine removal or hardness reduction), logo printing and packaging design. Our team works from your mould shape, dimensions and target performance, and we have developed more than 1,000 filtration solutions.
Standard models typically have an MOQ of 3,000–5,000 pcs, while custom models are evaluated case by case, usually 5,000–10,000 pcs. Standard samples ship in about 3–5 working days; custom samples take about 15–25 days. Stock standard items ship in 7–15 days, and OEM custom orders (including tooling) generally take 30–45 days, depending on complexity.
Replace it every 2–4 weeks. The exact interval depends on your local water hardness, sediment levels and how frequently the pet uses the fountain. In areas with harder water or multiple pets, the shorter end of that range is more appropriate.
