The Oltaven pet toilet filter cartridge is a finished activated-carbon filter built for smart cat litter boxes, automatic pet toilets, pet air cabins and pet deodorisers. It adsorbs the odour molecules pets leave behind — ammonia, hydrogen sulphide and TVOC-type volatile compounds — using high-iodine coconut shell activated carbon wrapped in PET structure material. It is made for pet-appliance brands, OEM buyers and distributors who need a replaceable odour filter matched to their own device cavity and replacement rhythm.
A finished filter is not simply carbon in a bag. The same activated carbon can behave quite differently depending on how it is pleated, framed, sealed and cut. Media decides the adsorption potential; forming decides how much of that potential the user actually experiences in the device.
In this cartridge, high-iodine coconut shell activated carbon provides the adsorption surface. The carbon is held within environmentally friendly PET structure material, which gives the cartridge its shape and its air path. The way that structure is assembled — the packing of carbon, the covering layers, the edge finishing and the cut outline — sets three things at once: how freely air moves through the cartridge, how long the carbon keeps working before it is saturated, and how well the piece fits the cavity it was designed for.
Oltaven sells the finished cartridge, not loose media. That distinction matters to a device maker: the delivered part is the one that has to drop into a moulded housing, survive shipping, and keep odour control steady across a replacement cycle.
Coconut shell activated carbon is chosen for its high iodine value, which relates to the internal surface available for adsorption. A high surface area gives the cartridge capacity to hold odour molecules, and the carbon grade can be adjusted when a customer's target market expects a longer or shorter service window.
A cartridge that resists airflow will move less air through the carbon, even if the carbon itself is capable. Forming therefore balances breathability against contact: the PET structure and the way the carbon is laid out keep the piece permeable while still exposing odour-laden air to the carbon. This is why two cartridges of similar outer size can feel different in service — the internal arrangement, not the footprint, often explains the difference.
Because pet toilets differ from brand to brand, the outline of the cartridge is part of its performance. Cutting, edge finishing and special shapes are matched to the customer's mould and device cavity, so the filter seats correctly and air passes where the device expects it to.
Clean handling protects the carbon before it ever reaches a customer. Oltaven produces in clean workshops and checks the finished cartridge through IQC, IPQC and OQC stages, so dust and loose material are controlled as part of the finished part rather than treated as an afterthought.
The cartridge is designed as an embedded filter for equipment that handles pet waste odour. Typical uses include:
In each case the cartridge is a replaceable consumable. The device maker specifies the cavity and the expected replacement rhythm; Oltaven shapes the cartridge to that specification so the end user can swap it without tools or guesswork.

Oltaven supports OEM/ODM work as a core part of the business, with more than 1,000 filter solutions developed to date. That experience is useful when a pet-appliance brand needs a cartridge matched to an existing housing rather than a catalogue part.
The manufacturing base in Zhongshan, Guangdong, China, covers 50,000 m², including six cleanrooms totalling 20,000 m². Production runs on multiple automated lines with monthly capacity in the millions of pieces, which supports repeat programmes rather than one-off batches.
Quality is backed by an in-house laboratory accredited by CNAS, able to issue reports on filtration efficiency, dust-holding capacity and resistance. The company holds IATF 16949 certification (obtained in 2024) and ISO 9001, ISO 14001 and ISO 45001 system certifications. Products meet REACH and RoHS environmental requirements, and compliance documents can be supplied on request. Quality control runs through IQC, IPQC and OQC across the process.
To quote accurately, Oltaven needs a few details: your device or litter-box model, the cartridge size or a drawing, the airflow your device moves through the filter compartment, the operating conditions in which it runs, and the quantity you expect per order and per year. If you already have a sample of the current cartridge, that is the fastest starting point.
Send these details through the contact page and the team will respond with a proposal for media, form and packaging. Whether you are developing a new pet appliance or replacing a supplier, Oltaven is open to a long-term OEM/ODM partnership.
Resistance depends less on outer size than on how the filter is formed. The carbon loading, the PET structure and the internal air path determine how freely air moves through the cartridge. Two cartridges with the same footprint can therefore feel different inside the same device. Oltaven adjusts the internal arrangement during sampling so the finished part suits the device's airflow.
It starts with your device model, a cavity drawing or a current sample, plus the expected replacement rhythm and target market. Oltaven then proposes carbon grade, structure, outline and packaging, and produces a sample for fit and airflow checks. Once you validate odour control and fit, the specification is fixed for production.
Yes. Size and shape are made to order, and cutting, edge finishing and special shapes can follow your mould and device cavity. This is how the cartridge seats correctly in different pet-appliance brands. Share a drawing or sample and the outline can be matched to it.
The suggested replacement interval is 1–3 months, depending on the number of pets and how often the device runs. Households with more pets or heavier device use sit at the shorter end. Carbon loading can be adjusted per project to match the replacement rhythm your market expects.
Yes. Sampling is part of the OEM/ODM workflow: a cartridge is produced for fit and airflow checks in your device, and relevant test documents can accompany it. A quote follows once the size, carbon grade, packaging and quantity are agreed. Send your device details through the contact page to begin.
Minimum order quantity and lead time are agreed per project, because they depend on the size, carbon grade and packaging format. Oltaven runs multiple automated lines with monthly capacity in the millions of pieces, which supports repeat programmes. Share your expected order volume and the team will confirm both figures with the quotation.
The in-house CNAS-accredited laboratory can issue reports on filtration efficiency, dust-holding capacity and resistance. The company holds IATF 16949 (2024) and ISO 9001, ISO 14001 and ISO 45001 certifications, and products meet REACH and RoHS requirements, with compliance documents available on request. Production follows IQC, IPQC and OQC checks in cleanrooms totalling 20,000 m².
A finished cartridge is the part that has to fit your housing, survive shipping and keep odour control steady across a replacement cycle. Oltaven forms the carbon into a PET structure, cuts and finishes the outline, and checks the finished part through IQC, IPQC and OQC. Buying the finished cartridge means the media choice and the forming are already resolved together. Tell us about your device and we will propose a specification.
