The Oltaven pet water dispenser filter cartridge is a drop-in water filter for cat and dog automatic drinking fountains and smart circulating water dispensers. It combines high-density PET non-woven fabric, ion exchange resin and coconut shell activated carbon to catch hair and floating particles, reduce residual chlorine and odours, and soften hard water. It is made for pet-product brands, fountain makers and distributors who want a finished, customisable cartridge rather than loose filter media.
A filter is often described by its media, but the media alone is not the product. The same coconut shell activated carbon can behave quite differently depending on how it is packed, how the water is made to pass through it, and how the finished cartridge is assembled. Oltaven sells finished filters, so the work starts with the media and ends with a part that fits a specific fountain and performs predictably.
The construction here is layered. A high-density PET non-woven fabric forms the outer stage, catching hair, dust and visible particles that pets carry into the bowl. Behind it, coconut shell activated carbon adsorbs residual chlorine and odours that affect how water tastes and smells. Ion exchange resin then works on hardness, exchanging hardness ions and helping to reduce the mineral scale that can build up in a fountain. Each layer has a job, and the order in which water meets them shapes what the cartridge can do.
Forming turns those layers into a cartridge. The media has to be held in place so water flows through the intended path instead of bypassing the treatment layers, and the housing has to keep its shape through weeks of continuous wet use. That is why we treat pleating, framing and sealing as part of the performance specification, not as packaging around it.
Three outcomes matter to a fountain brand: how much chlorine and odour is taken out, how hard the water is to push through the cartridge, and how long the cartridge lasts before it needs changing. Media choice and forming decisions set all three.
Efficiency depends on the amount and quality of the activated carbon and resin, and on contact time. Water that passes too quickly through a thin carbon layer has less chance to give up chlorine. A denser carbon bed or a longer flow path raises removal, but it also changes resistance.
Resistance is the pressure needed to move water through the finished part. The non-woven fabric, the carbon bed and the resin all contribute. A tight structure that traps fine hair well can also make the pump work harder, which matters on small fountains with low-power pumps. Balancing the two is a forming question as much as a media question.
Capacity is how much contamination the cartridge can hold before performance drops. A larger carbon mass and a well-supported structure can hold more, but the cartridge must still fit the fountain's filter slot. This is why custom sizes and media ratios are developed together rather than chosen separately.
Sealing and framing decide whether water follows the intended path. If water slips past the media at an edge, the rated media never gets used and real-world performance falls short of the bench result. A well-formed cartridge keeps the flow inside the treatment layers for its whole service life.
The cartridge is built for pet drinking-water equipment: cat and dog automatic water fountains, smart constant-temperature circulating fountains, and other pet water purification devices. In these machines the filter usually sits in a small compartment and is changed by the owner, so fit and easy replacement matter as much as filtration.
Typical use is household fountains where tap water is circulated for pets. The non-woven stage deals with hair and dust that pets bring to the bowl, the carbon stage addresses chlorine and odour, and the resin stage helps with hard-water areas. Because local water quality and drinking frequency vary, the replacement interval is set by the conditions rather than by a single fixed number.

Oltaven is an OEM/ODM filter manufacturer, and that capability is the centre of how this cartridge is made. We have developed more than 1,000 filtration solutions for customers, which means a new fountain model can often start from an existing material combination rather than from a blank page.
Production runs in a 50,000 m² plant in Zhongshan, Guangdong, China, including six cleanrooms with a combined area of 20,000 m². Our own laboratory is CNAS-accredited and can issue reports on filtration efficiency, dust holding capacity and resistance. The plant operates under ISO 9001, ISO 14001 and ISO 45001 systems, and IATF 16949 was achieved in 2024. Products meet REACH and RoHS requirements, and compliance documents can be supplied. With more than 20 years of filtration development and manufacturing, we have exported to Europe, the United States, Japan and South Korea for over 20 years.
To quote accurately, please send your device or fountain model, the cartridge size or a drawing, the airflow or water flow figures, the operating conditions (water hardness, temperature, daily drinking volume), and your target quantity. Our team will come back with a material proposal and a production plan. Contact Oltaven to begin.
Resistance is set by the finished structure, not only by the outer dimensions. The density of the non-woven fabric, the carbon bed and the resin all affect how hard water is to push through, and so does the internal flow path created by framing and sealing. Two cartridges can share a footprint yet differ in resistance because their media ratios and forming are different.
It starts with your fountain model, the filter slot size or a drawing, and the water flow and operating conditions. From there we propose a media combination and a formed structure, then produce samples for your evaluation. Once the specification, logo and packaging are confirmed, the project moves to volume production.
The coconut shell activated carbon and ion exchange resin are combined to reduce residual chlorine and odours, and the material system is designed for chlorine removal above 95%. Under normal use at roughly 500–1,000 ml of water per day, a cartridge lasts about 2–4 weeks, depending on local water quality and drinking frequency.
Yes. We support OEM/ODM work on mould shape, dimensions and filter material ratio, as well as logo and packaging. Customisation is handled through the 20,000 m² clean workshop and CNAS-level laboratory, so fit and filtration can be developed together rather than adjusted afterwards.
Yes. Standard samples are usually sent within 3–5 working days, while custom samples such as a new size or special media ratio take about 15–25 days. Samples can be accompanied by CNAS test reports and material safety documents to support your evaluation and quoting.
For standard models the MOQ is typically 3,000–5,000 pcs, and for custom models it is assessed by project, generally 5,000–10,000 pcs. Standard stock items ship in about 7–15 days; OEM custom orders including tooling generally take 30–45 days, depending on complexity.
The suggested interval is 2–4 weeks. Hard water, heavy pet drinking or visible hair build-up on the non-woven surface can shorten it, while softer water and lighter use may allow the longer end of the range. The owner should check the cartridge during routine fountain cleaning.
We have exported to Europe, the United States, Japan and South Korea for over 20 years. Products meet REACH and RoHS requirements, and compliance documents can be provided. Please send your destination market and requirements through our contact page so we can confirm the documents you need.
