This HEPA-grade dust filter box is a high-efficiency filter cartridge designed to remove PM0.3 particles at ≥ 99.99% efficiency while also adsorbing VOCs, thanks to its PTFE membrane and activated carbon layers. It is intended for clinical ventilator and anesthesia circuits, industrial respirators, and high-spec air purification or oxygen concentrator equipment. Zanxis manufactures it under GMP for medical supplies, with full customization to your drawing. The sections below list the parameters to confirm, how samples and lab reports verify them, and how the product is built and tested.

Before you approve a drawing or place a volume order, confirm the filtration efficiency you actually need: the standard product is rated at ≥ 99.99% for PM0.3, and H13/H14 grades are available. The pressure drop at your operating airflow should be checked against the device's allowable resistance, because a higher-efficiency grade will change the resistance curve. Confirm the VOC adsorption capacity and the type of activated carbon if the application involves anesthetic gases or industrial solvents. For fit, verify the housing dimensions, the seal ring compression, and the connector geometry against your device interface. Also agree on the sampling plan and the acceptance criteria for efficiency, resistance, and airtightness before mass production. Zanxis can issue CNAS lab reports for efficiency, dust holding, and resistance so these values are documented rather than assumed.
The filter box combines a PTFE microporous membrane, glass fiber layers, and composite activated carbon in a housing molded from non-toxic medical-grade ABS or PC. The seal is a medical silicone ring joined by ultrasonic welding, which is intended to prevent air bypass around the media. Zanxis molds the housing to your drawing, so the outer dimensions, inlet/outlet configuration, and mounting features are fixed at the sampling stage rather than adapted from a catalog part. The product is used in clinical ventilator and anesthesia circuits, in industrial gas masks and positive-pressure respirators, and in high-spec fresh air purification and oxygen generation equipment. Because the same core media can be supplied in H13 or H14 grades, the choice should be made together with the device's resistance budget and the contaminants present. Replace the filter according to your device manufacturer's schedule or when resistance rises beyond the device's specified limit; the filter itself is not cleanable and should be replaced as a sealed unit.
Zanxis operates its own CNAS-accredited laboratory, which can issue reports on filtration efficiency, dust holding capacity, and resistance for each batch. Quality control follows IQC, IPQC, and OQC stages from incoming media to final inspection. The company holds GMP for medical supplies, IATF 16949 (obtained in 2024), ISO 9001, ISO 14001, and ISO 45001 system certificates, and products meet REACH and RoHS requirements with compliance documents available.Zanxis has more than 20 years of filtration R&D and manufacturing experience, exports to Europe, the United States, Japan, and South Korea, and supports OEM/ODM customization of dimensions, structure, media grade, housing material, logo, and packaging, with over 1,000 filtration solutions developed. The address is Zhongshan, Guangdong, China.
To receive a sample and the corresponding test report, send the device or vehicle model, the required dimensions or a drawing, the airflow or water flow at the operating point, the operating conditions (temperature, humidity, contaminants), and the estimated quantity. Zanxis will confirm the feasible HEPA grade and seal configuration, then quote sample lead time and production MOQ. Use the contact page to start the review.
Yes. Zanxis has a CNAS-accredited laboratory that issues reports on filtration efficiency, dust holding capacity, and resistance. These reports can be provided with samples or production batches so you can verify the ≥ 99.99% PM0.3 efficiency claim against your specification.
Sample preparation typically takes 7–15 days after the drawing and media grade are confirmed. Validation time on your side depends on your device testing; once you sign off the sample and acceptance criteria, production lead time is confirmed.
For standard specifications, the MOQ is usually 1,000 pieces. For custom molded housings, the MOQ is agreed based on tooling and development complexity. Sample orders are available before volume commitment.
Standard items ship in about 7–15 days, while custom production batches typically take 25–35 days. Zanxis will confirm the schedule in the quotation based on your quantity and configuration.
Replace the filter according to your device manufacturer's maintenance schedule, or when resistance rises beyond the device's specified limit. The filter is a sealed unit and is not intended to be cleaned and reused.
Yes. Zanxis molds the housing to your drawing and can supply medical silicone ultrasonic-welded seal rings to prevent air leakage. Send your device model and interface drawing, and the team will confirm feasible dimensions and HEPA grade.
The product is offered in HEPA H13 and H14 grades, with the standard efficiency rated at ≥ 99.99% for PM0.3. The grade choice should be matched to your device's allowable resistance and the contaminants present.
