This desktop air purifier filter is a cylindrical HEPA filter combined with granular activated carbon, designed to remove particulate matter and gaseous pollutants such as formaldehyde and odors. It is offered by Zanxis for desktop and bedside air purifiers, car purifiers, and fresh-air modules. The filter uses high-efficiency PP, PET composite, or PTFE media with high-iodine coconut-shell carbon, and is available in filtration grades from F7 to H13. It is intended for OEM and ODM customers who need verifiable performance and flexible dimensions.

Before selecting a filter, confirm the following parameters with your device specifications. These values directly affect fit, efficiency, and replacement interval.
We recommend a structured sample validation process to confirm performance before mass production.
The filter combines a HEPA layer for particle removal with a granular activated carbon layer for gas-phase adsorption. The media is pleated to increase surface area, and the carbon is evenly distributed to avoid bypass. The cylindrical format is common for desktop purifiers, while rectangular and custom shapes are available for other devices. Sponge sealing edges ensure a tight fit and prevent air bypass. The filter is designed for easy replacement by end users. For optimal performance, replace the filter every 6–12 months under normal use (8 hours per day), depending on air quality and usage intensity.
Zanxis operates a CNAS-accredited laboratory that provides test reports for filtration efficiency, dust holding capacity, and resistance. These reports document the performance of each filter design and are available for customer review. Our quality management system is certified to ISO 9001, ISO 14001, and IATF 16949 (obtained in 2024), and we implement IQC, IPQC, and OQC throughout production. The manufacturing plant covers 50,000 square meters, including six cleanrooms totaling 20,000 square meters. With over 20 years of experience in filter development and manufacturing, we have exported to Europe, the United States, Japan, and South Korea. Our products comply with REACH and RoHS regulations, and we can provide compliance documentation. We support OEM/ODM customization of dimensions, structure, media grade, frame material, logo, and packaging, and have developed more than 1,000 filter solutions.
To receive samples and test reports, please provide the following details: your device or vehicle model, required dimensions or a drawing, airflow rate or water flow (if applicable), operating conditions, and estimated quantity. Our team will respond with a tailored proposal and sample timeline. Contact us to start the verification process.
Yes. Our CNAS-accredited laboratory issues test reports covering filtration efficiency, dust holding capacity, and resistance for each filter design. These reports are available for customer review and verification. We can provide them alongside samples for your evaluation.
Sample fabrication typically takes 7–15 working days, depending on customization complexity. After samples are ready, we conduct laboratory testing and provide reports. You can then perform fit checks and performance validation in your device. The entire process from requirement review to sign-off usually takes 3–5 weeks.
Standard models have an MOQ of 1,000–2,000 pieces. Customized models require an MOQ to be negotiated based on the specific design. We also support flexible trial orders during the sample stage.
Mass production lead time is typically 25–35 days after sample approval and order confirmation. For long-term customers, we can arrange stock or VMI management to shorten delivery cycles.
Under normal use (8 hours per day), the filter typically lasts 6–12 months, depending on air quality and usage intensity. We can integrate RFID tags or timer/differential pressure sensing options to help end users determine replacement timing accurately.
Yes. We offer 100% OEM/ODM customization, including dimensions, shape, media grade (F7 to H13), carbon type, frame material, and sealing. Provide your device model and air duct dimensions, and our engineers will design a filter to match.
Please share your device model, required dimensions or drawing, target airflow rate, filtration efficiency, operating conditions, and estimated quantity. With these details, we can prepare a precise quotation and propose a filter specification. Contact us to start the process.
