Ranveth's pet water dispenser filter cartridge is a drop-in purification unit for cat and dog drinking fountains. It filters out stray hair and fine debris, strips residual chlorine and odours with coconut-shell activated carbon, and softens hard water using ion-exchange resin. It is built for pet-product brands, OEM buyers and fountain manufacturers who need a dependable filter that keeps water clean and palatable.
The cartridge is not a single material dropped into a housing. It is a layered flow path in which each medium has a defined job, and the order of those jobs is what determines how long the filter lasts and how much resistance it adds to the pump.
Water first meets a high-density PET non-woven fabric. This outer layer is the physical gate: it traps hair, dust and visible particles before they can reach the inner media. Keeping solids on the surface protects the carbon and resin downstream, so the chemical media are not blinded by debris. The non-woven is selected for consistent pore size and enough mechanical strength to hold its shape under the water flow of a typical fountain pump.
Behind the non-woven sits high-efficiency ion-exchange resin. Its role is to soften water by exchanging hardness ions, which reduces the mineral load that can cause scale on fountain parts and makes the water easier for pets to drink. The resin is paired with premium coconut-shell activated carbon, a medium with a well-developed micropore structure that adsorbs residual chlorine and odour-causing compounds. Coconut carbon is chosen here because it combines fast kinetics with a clean, low-dust handling profile, which matters in a small cartridge that pets drink from continuously.
This pairing drives the three performance outcomes a buyer cares about. Efficiency comes from the sequence: solids are removed first, so the carbon and resin work on dissolved contaminants rather than on debris. Airflow resistance — more precisely, water-flow resistance — is managed by balancing layer thickness and media grade so the cartridge does not starve the pump. Service life is a function of how much chlorine and hardness the media can hold before exhaustion, which is why the recommended replacement window is 2–4 weeks depending on local water quality and how often the pet drinks.

The cartridge is designed for the small pumps and low-flow loops found in pet drinking appliances. Typical installations include automatic cat and dog water fountains, smart constant-temperature fountains that circulate and gently warm drinking water, and compact pet water-purification units. In each case the filter sits in the recirculating stream, so it repeatedly contacts the same water and gradually removes chlorine, odour and hardness while the non-woven layer keeps hair and dust out of the media bed.
Because the media are selected for potable-water contact and the production environment is controlled, the cartridge is also suited to OEM programmes where a fountain brand wants a filter that can be private-labelled and shipped with material safety documentation. It is not intended for industrial water treatment or for any application outside pet drinking appliances.
Ranveth supports OEM and ODM work on this cartridge, including non-standard dimensions, housing shape, filter-material ratio and branding. To quote accurately and avoid repeated sampling rounds, please send the following with your inquiry:
If you already have a reference sample or a competitor cartridge you want to match, include it in the discussion; our engineering team can propose a media pairing and layer build around it.
Media choices on this cartridge are backed by testing, not assumption. Ranveth's in-house laboratory is CNAS-accredited and can issue reports on filtration efficiency, contaminant holding capacity and resistance, so the carbon-and-resin pairing can be verified against the performance you specify.
Production takes place in a 50,000 m² plant in Zhongshan, Guangdong, China, which includes six cleanrooms totalling 20,000 m². Cleanroom assembly reduces the risk of contamination during cartridge build, which matters for a product that sits in drinking water. The site operates under IATF 16949, obtained in 2024, and under ISO 9001, ISO 14001 and ISO 45001 systems, with IQC, IPQC and OQC controls running from incoming material to finished goods.
Ranveth has more than 20 years of filtration research and manufacturing experience and has exported to Europe, the United States, Japan and Korea for over 20 years. Products can be supplied with REACH and RoHS compliance documentation, and the OEM/ODM team has developed more than 1,000 filtration solutions, which helps shorten the path from a drawing to a production-ready cartridge.
To move forward, tell us your device model, the size or drawing you are working to, the airflow or water flow of your fountain, the operating conditions, and the quantity you expect to order. With those details we can recommend a media pairing, confirm MOQ and lead time, and arrange samples for your evaluation. Contact our team to start the conversation.
It uses a layered build of high-density PET non-woven fabric, high-efficiency ion-exchange resin and premium coconut-shell activated carbon. The non-woven removes hair and particles first, the resin softens water, and the carbon adsorbs residual chlorine and odours. This order protects the inner media and supports a 2–4 week service life under normal use.
The coconut-shell activated carbon and ion-exchange resin are selected for chlorine removal and odour control, and the layered structure is designed to keep those media working on dissolved contaminants rather than debris. Under normal conditions the suggested replacement interval is 2–4 weeks, depending on local water quality and how often the pet drinks. Performance can be verified through reports from our CNAS-accredited laboratory.
Yes. We support OEM/ODM customisation of dimensions, housing shape and filter-material ratio, using a 20,000 m² cleanroom and a CNAS-accredited laboratory. Send your device model or a dimensioned drawing and the target flow rate, and our engineers will propose a media pairing and layer build for your fountain. Branding and packaging can also be customised.
MOQ and lead time depend on whether the cartridge is a standard size or a custom build, so we confirm both after reviewing your drawing, flow data and quantity. Providing expected annual volume with your inquiry helps us give a firm schedule. Samples can be arranged before you commit to a production order.
Yes. We encourage sampling so you can test fit, flow and water taste in your own fountain. To quote, we need the device model, size or drawing, water flow, operating conditions and quantity. Contact our team through the inquiry form and we will respond with a proposal.
The recommended replacement interval is 2–4 weeks. The exact timing depends on local water hardness and chlorine levels and on how frequently the pet drinks. In hard-water areas or busy multi-pet households, changing at the shorter end of that range helps maintain flow and water quality.
The materials meet US EPA and NSF standards for food-grade, non-toxic safety, and production follows ISO 9001, ISO 14001 and IATF 16949 systems. The cartridge is assembled in cleanrooms to reduce contamination risk. Compliance documentation, including REACH and RoHS files, can be provided with your order.
Please send the device model or a dimensioned drawing, the required size and shape, the fountain's water flow or airflow data, operating conditions such as water quality and temperature, and your expected quantity. With those details we can recommend a media pairing, confirm MOQ and lead time, and arrange samples. <a href="/en/contact">Contact us</a> to begin.
