FILTER MEDIA / ROLLS · SHEETS · DIE-CUT
The Oltaven aquarium descaling filter cartridge is a finished filter that combines a PET non-woven structure with high-quality coconut shell activated carbon granules to reduce turbidity, remove residual chlorine, control odours and limit scale build-up in aquarium water. It is designed for household and commercial fish tank filters, aquarium purification systems and pet automatic water dispensers. This page explains how media selection and forming choices determine the finished filter’s efficiency, resistance and capacity, so you can specify the right cartridge for your application.
Media alone does not make a filter. The same activated carbon can perform very differently depending on how it is pleated, framed and sealed. At Oltaven, we sell finished filters, not just media. Our engineering team works from the application backwards: water chemistry, flow rate and maintenance interval define the media grade; the housing and installation space define the forming method; and the required seal integrity defines the assembly process. This integrated approach ensures that the cartridge you receive delivers the filtration performance you expect, not just on the lab bench but in your customers’ aquariums.
Three factors govern the finished filter’s behaviour: the media, the forming and the sealing.
Media choice. The coconut shell activated carbon used in this cartridge is selected for its high iodine value, which relates to its adsorption capacity for residual chlorine and organic odours. The carbon granules are combined with a PET non-woven fabric that provides physical interception of suspended particles. The ratio of carbon to non-woven, the granule size and the fabric’s pore structure all influence how quickly water passes through and how much contaminant is removed per pass.
Forming. Pleating increases the surface area available for filtration within a compact cartridge. The pleat height, pleat count and the way the media is folded affect both the resistance to water flow and the dirt-holding capacity. A tighter pleat pack offers more area but can raise resistance; a more open pack reduces resistance but may shorten the interval between replacements. Oltaven balances these trade-offs during prototyping, using the customer’s target flow rate and maintenance cycle as the design brief.
Sealing and framing. The end caps and frame keep the media in place and prevent bypass. A poor seal allows unfiltered water to bypass the carbon, reducing efficiency regardless of media quality. Oltaven assembles cartridges in cleanrooms and inspects seals as part of in-process quality control, so the finished filter performs as intended.
The Oltaven aquarium descaling filter cartridge is used in:
In these applications, the cartridge reduces water turbidity, adsorbs residual chlorine (Cl₂), removes odours and helps limit scale formation. By extending the interval between water changes, it supports easier aquarium maintenance. The recommended replacement interval is 2–4 weeks, depending on tank volume and water pollution level.

Oltaven brings over 20 years of filtration product development and manufacturing experience to every project. Our OEM/ODM capability is central to what we offer: we have developed more than 1,000 filtration solutions, supporting customisation of size, structure, filter media grade, frame material, logo and packaging. Our production base covers 50,000 m², including six cleanrooms totalling 20,000 m², where cartridge assembly and packaging take place under controlled conditions. Our in-house laboratory is CNAS-accredited and can issue test reports for filtration efficiency, dust holding capacity and resistance. We are certified to IATF 16949 (obtained in 2024) and hold ISO 9001, ISO 14001 and ISO 45001 system certifications. Our products comply with REACH and RoHS environmental regulations, and we can provide compliance documents. Quality control follows IQC, IPQC and OQC throughout the process. Our address is Zhongshan, Guangdong, China.
Throughout the process, a dedicated project manager coordinates communication to ensure efficiency.
To discuss a custom aquarium descaling filter cartridge for your brand, please provide the following details: device or vehicle model, required size or drawing, airflow or water flow, operating conditions (water hardness, tank volume, temperature), and estimated order quantity. Our team will respond with a tailored proposal. Contact us to start the conversation. We look forward to partnering with you.
Resistance depends on the media and forming choices inside the cartridge. Two cartridges with identical outer dimensions can have different pleat counts, pleat heights, carbon granule sizes or non-woven pore structures. A tighter pleat pack offers more surface area but can increase resistance, while a more open pack reduces resistance but may shorten the replacement interval. Oltaven tunes these variables during prototyping to meet your target flow rate.
An OEM project starts with your requirements: device or vehicle model, size or drawing, airflow or water flow, operating conditions and estimated quantity. Our engineering team reviews these and proposes a solution, typically within 3 working days. We then produce samples (usually 7–10 working days) for your approval before batch production.
Yes. Oltaven supports deep non-standard customisation based on your moulds and sizes. We can adjust dimensions, structure, media grade, frame material, logo and packaging. Our production base includes 20,000 m² of clean workshop space and a CNAS testing centre, enabling us to deliver custom cartridges that fit your system.
Standard models typically have an MOQ of 3,000–5,000 pieces, while customised models have an MOQ of 5,000–10,000 pieces, depending on specification and packaging complexity. For lead time, standard stock orders ship in 7–15 days; custom orders generally ship 30–45 days after sample confirmation.
We provide free standard samples to B2B customers with clear purchasing intent (customer covers courier cost). For custom samples, the process is: you provide requirements/drawings/reference samples; our engineering team confirms the plan within 3 working days; we produce samples in 7–10 working days; we send samples with CNAS test reports; and after your approval, we schedule production.
The recommended replacement interval is 2–4 weeks, depending on tank volume and water pollution level. In practice, you may need to replace it more often in heavily stocked tanks or when water hardness is high. Oltaven can help you set a suitable interval for your market by adjusting the media formulation.
We control consistency through IQC, IPQC and OQC across the production process. Key checks include media fill weight, seal integrity, flow rate and appearance. Our CNAS-accredited laboratory can issue test reports with international recognition, helping ensure each batch meets the same performance criteria.
The production system conforms to ISO 9001, ISO 14001 and IATF 16949, and the materials have passed US EPA, NSF and medical supplies GMP standard audits. Oltaven also holds ISO 45001 certification and can provide REACH and RoHS compliance documents. These certifications reflect our commitment to quality and regulatory compliance.
