The Celrith Pet Water Dispenser Filter Cartridge is a replacement filter for automatic pet water fountains that removes chlorine, odours, and waterborne impurities while softening hard water. It combines high-density PET non-woven fabric, ion-exchange resin, and coconut-shell activated carbon to deliver cleaner, fresher-tasting water for cats and dogs. Designed for pet owners and OEM/ODM buyers, this cartridge helps maintain fountain hygiene and supports animal hydration.
Water in a pet fountain is not sterile. As pets drink, saliva, food particles, and hair enter the water. Municipal tap water also carries residual chlorine, which can give water an unpleasant taste and odour. In hard-water areas, dissolved minerals leave scale that coats the fountain pump and basin. These contaminants accumulate quickly, especially in fountains with recirculating water, and can discourage pets from drinking enough.
Left unmanaged, the result is a cycle of poorer water quality, more frequent cleaning, and potential equipment wear. A dedicated filter cartridge addresses these issues at the source by intercepting particles and adsorbing dissolved impurities before they affect the pet or the fountain.
Every contaminant places a specific burden on the fountain and its components. Hair and dust can clog pump impellers and reduce flow, leading to noisy operation or motor strain. Chlorine and organic odours are not removed by simple mechanical filtration, so they persist in the water and can taint the drinking experience. Hardness minerals form scale on heating elements (in heated fountains) and on pump surfaces, decreasing efficiency and shortening service life.
For pet owners, this means more frequent disassembly and scrubbing, and for OEMs, it can translate into higher warranty claims and customer dissatisfaction. The Celrith cartridge is engineered to relieve these loads by combining mechanical interception, adsorption, and ion exchange in a single replaceable unit.
The cartridge uses a layered approach. The outer high-density PET non-woven fabric captures hair, dust, and suspended particles, preventing them from reaching the inner media. This layer is durable and maintains structural integrity even when wet.
Inside, coconut-shell activated carbon adsorbs residual chlorine, odours, and certain organic compounds. Coconut-shell carbon is chosen for its high surface area and consistent pore structure, which support effective adsorption. Ion-exchange resin then targets hardness minerals, softening the water and reducing scale formation. Together, these media address the three main contaminant categories: physical, chemical (chlorine and odour), and mineral hardness.
The result is water that tastes fresher and is kinder to fountain components. The cartridge is designed for easy replacement, with a recommended interval of 2 to 4 weeks depending on local water quality and pet drinking frequency.

This filter cartridge is used by pet owners who want to improve water quality in automatic fountains for cats and dogs. It is equally suited to OEM and ODM customers—pet product brands, fountain manufacturers, and distributors—who need a reliable filtration component that can be customised to fit specific fountain models or to meet particular performance targets.
Typical applications include smart constant-temperature fountains and standard recirculating pet water dispensers. The cartridge is also used in larger pet water purification systems where consistent water quality is important.
Celrith products are manufactured in a facility that holds ISO 9001, ISO 14001, and ISO 45001 certifications, and our materials comply with REACH and RoHS regulations. We can provide compliance documentation upon request. Our in-house laboratory is CNAS-accredited and can issue test reports for filtration efficiency, dust holding capacity, and resistance, giving you dependable data for your own quality assessments.
Production takes place in a 50,000 m² plant, which includes 20,000 m² of cleanrooms across six dedicated cleanroom workshops. We are certified to IATF 16949 (obtained in 2024), reflecting our commitment to rigorous quality management. With over 20 years of experience in filtration and exports to Europe, the US, Japan, and South Korea, we have developed more than 1,000 filtration solutions and operate multiple automated production lines with a monthly capacity of millions of pieces. Full IQC, IPQC, and OQC processes are in place to ensure consistent quality.

It removes floating hair and micro-dust through a high-density PET non-woven layer, adsorbs residual chlorine and odours with coconut-shell activated carbon, and reduces water hardness using ion-exchange resin. This three-stage approach targets the most common impurities in pet fountain water.
Under normal use, replace the cartridge every 2 to 4 weeks. The exact interval depends on your local water quality and how often your pet drinks. Regular replacement ensures consistent flow and filtration efficiency.
Yes, standard samples are usually shipped within 3–5 working days. For customised samples, the lead time is about 15–25 days. We can also provide CNAS test reports and material safety certificates with the samples.
For standard models, the MOQ is typically 3,000–5,000 pieces, with a lead time of 7–15 days for stock items. Customised models generally require 5,000–10,000 pieces, and lead time is 30–45 days depending on complexity.
Absolutely. We offer OEM/ODM services, including custom dimensions, housing structure, filter media formulation (e.g., enhanced chlorine removal or scale inhibition), logo printing, and packaging design. Our team will work with you to develop a solution that matches your specifications.
The coconut-shell activated carbon is specifically selected for high chlorine adsorption. In-house testing shows a chlorine removal rate of over 95%, ensuring water is fresh and free from chlorine odour.
The cartridge is produced under ISO 9001, ISO 14001, and IATF 16949 systems. Materials meet US EPA and NSF standards for food-grade safety, and we can provide REACH and RoHS compliance documents. Our CNAS-accredited lab tests each batch for filtration performance.
