The Celrith disc-shaped water dispenser filter reduces TDS and removes chlorine, odour, and physical debris from drinking water in pet water fountains. It combines high-density PET non-woven fabric, ion-exchange resin, and coconut-shell activated carbon to soften water and improve taste. This filter is designed for pet owners, fountain manufacturers, and private-label brands that need a reliable, customisable filter for automatic pet water dispensers and smart circulating systems.
Water in a pet fountain is not static. Every time an animal drinks, it leaves behind saliva, food particles, and loose hair. These organic materials become a food source for bacteria, and the pump circulates them through the entire system. Meanwhile, tap water brings its own load: residual chlorine, dissolved minerals that cause hardness, and trace metals that affect taste and smell. Over days, the water develops an odour and a visible film, and the fountain that was meant to encourage hydration becomes a less appealing drinking station.
The Celrith filter addresses this problem at the source. The outer PET non-woven layer traps hair, dust, and floating debris before they reach the inner filtration media. Inside, coconut-shell activated carbon adsorbs chlorine and odour-causing compounds, while ion-exchange resin targets calcium and magnesium ions that make water hard. The result is water that looks clearer, smells fresher, and tastes more inviting to pets. For multi-pet households or areas with hard water, this combination reduces the frequency of full fountain cleanings and helps maintain water quality between changes.
When debris and scale are allowed to accumulate, the consequences extend beyond water quality. Hair and particles can clog pump impellers, reducing flow rate and causing the motor to work harder. Mineral scale builds up on heating elements in fountains with temperature control, reducing heat transfer and increasing energy consumption. Odour-causing bacteria form biofilms on reservoir walls and tubing, which are difficult to remove without disassembly. In commercial settings, such as pet boarding facilities or veterinary clinics, the downtime and labour required to clean scaled or clogged fountains add up quickly.
By intercepting contaminants early, the Celrith filter reduces the load on pumps, heaters, and plumbing. Cleaner water means less scale formation on hot surfaces and fewer particles reaching moving parts. The filter itself is designed to be replaced regularly, so the system avoids the buildup that leads to costly repairs or premature equipment failure. For OEM partners, this translates into fewer warranty claims and higher customer satisfaction, as end users experience consistent performance throughout the filter's service life.
The Celrith disc-shaped filter is built around a three-stage filtration approach. First, the high-density PET non-woven fabric acts as a pre-filter, capturing hair, dust, and larger particles. Second, the coconut-shell activated carbon layer adsorbs chlorine, organic compounds, and odours. Third, the ion-exchange resin softens water by exchanging hardness ions for sodium or hydrogen ions, depending on the formulation. This multi-layer construction is housed in a disc format that fits standard pet fountain designs.
Celrith manufactures this filter in a 20,000 m² cleanroom environment, part of a 50,000 m² production facility in Zhongshan, Guangdong, China. The company operates a CNAS-accredited laboratory for in-house testing of filtration performance, and production follows ISO 9001, ISO 14001, and IATF 16949 quality systems. For OEM/ODM customers, Celrith offers customisation of filter size, shape, media ratio, and packaging, supported by a team that has developed over 1,000 filtration solutions. The filter materials meet REACH and RoHS requirements, and compliance documentation is available upon request.

This filter is primarily used by pet owners who operate automatic water fountains for cats and dogs. It is equally suited to pet-related businesses such as grooming salons, boarding kennels, and veterinary clinics that maintain multiple water stations. For fountain manufacturers and brands, Celrith provides OEM/ODM services to integrate the filter into new or existing product lines. The disc format is compatible with many mainstream pet fountain models, and custom dimensions can be developed to match specific housing designs. Whether the goal is to reduce TDS for pets with urinary sensitivities or to improve the overall drinking experience, this filter offers a practical solution.
Celrith operates a 50,000 m² manufacturing plant in Zhongshan, Guangdong, China, which includes 20,000 m² of cleanroom space across six cleanrooms. The company holds ISO 9001, ISO 14001, and ISO 45001 certifications, and has been IATF 16949 certified since 2024. Products comply with REACH and RoHS regulations, and Celrith can provide documentation to support customer compliance requirements. The CNAS-accredited laboratory enables in-house testing of filtration efficiency and material safety, while automated production lines support a monthly capacity of several million units. With over 20 years of experience in filtration and exports to Europe, the United States, Japan, and South Korea, Celrith offers stable supply and consistent quality for OEM and ODM projects.
To receive a tailored quote or discuss a custom filter project, please contact us through our contact page. To help us respond efficiently, include the following details: your device or vehicle model, required filter size or a drawing, target airflow or water flow rate, operating conditions (such as water hardness and temperature), and estimated order quantity. Our team will review your requirements and provide recommendations, samples, and pricing. We look forward to supporting your filtration needs.
The filter removes floating debris such as hair and dust, residual chlorine, odours, and hardness minerals like calcium and magnesium. It achieves TDS reduction through ion-exchange resin, with typical removal rates of 60%–90% depending on water quality and flow rate. It also improves water taste and clarity for pets.
The ion-exchange resin exchanges hardness ions for sodium or hydrogen ions, effectively lowering TDS. Coconut-shell activated carbon adsorbs chlorine and organic compounds, while the PET non-woven layer captures physical particles. Together, they soften water and remove contaminants that affect taste and odour.
The disc-shaped design fits many mainstream pet water fountains. For specific models, Celrith offers customisation of size, shape, and connection details. Please provide your fountain model or a drawing, and our team can confirm compatibility or develop a custom-fit solution.
Yes, samples are available for evaluation. Standard samples are typically shipped within 3–5 working days, while custom samples may take 2–4 weeks depending on complexity. Each sample comes with technical specifications and test reports to support your assessment.
For standard specifications, the MOQ is typically 5,000–10,000 pieces. Custom OEM orders generally start at 10,000 pieces, depending on complexity. Standard lead time is 15–25 days; custom orders including tooling may take 30–45 days. Monthly capacity reaches several million units to support large volumes.
Under normal use, replace the filter every 2–4 weeks, depending on local water hardness, number of pets, and drinking frequency. Regular replacement prevents scale buildup and maintains flow rate. Celrith can adjust filter media ratios to optimise lifespan for specific market needs.
