Cleantop gas filter boxes use high-efficiency filter materials, achieving filtration efficiency levels of HEPA H13/H14 (≥99.97% for 0.3μm particles), effectively intercepting bacteria, viral aerosols, particulate matter, and odors. The product is widely applicable for medical ventilators, anesthesia machines, oxygen generators, and emergency respiratory devices, ensuring the cleanliness and safety of patients' respiratory pathways. We can also customize solutions with different efficiency levels (HEPA + activated carbon composite structure) based on specific device models and filtration requirements.

Cleantop has passed ISO 9001, ISO 14001, ISO 45001 system certifications and obtained IATF16949 automotive industry certification and GMP certification for medical supplies in 2024. Our production system fully complies with the regulatory requirements for medical-grade products. Additionally, our products have passed multiple international certifications such as Europe's BSC1, the US EPA, NSF, and SOP, and are exported to markets in Europe, the United States, Japan, and South Korea. For gas filter boxes for medical ventilators, we can assist customers in completing the necessary test reports and technical documents for FDA, CE (MDR), and other end registrations.

We have over 20 years of experience in the development and production of filtration products and a reserve of thousands of solutions, fully supporting OEM/ODM customization services. The customization range includes: the appearance structure of the filter box (size, interface, latch design), filter material combinations (HEPA, activated carbon, antibacterial coatings, etc.), filtration efficiency levels, shell materials (medical-grade ABS, PC, etc.), as well as logo printing, colored packaging, manuals, etc. We have a professional R&D team that can complete everything from drawing design, mold development to small batch trial production in one stop, typically with a development cycle of 30-45 days.

The Cleantop factory covers an area of 50,000㎡, which includes six clean workshops totaling 20,000㎡, meeting the clean production requirements for medical-grade products. We have established a nationally recognized CNAS testing center that can independently carry out full testing for filtration efficiency, resistance, dust holding capacity, sealing, and air-tightness. Quality control processes cover incoming material IQC, process IPQC, finished product FQC, and outgoing shipment OQC, with each batch of products accompanied by a testing report, ensuring batch consistency and traceability, which is our core guarantee for continuously serving high-end customers from Europe, the United States, and Japan.

The lifespan of the gas filter box depends on actual working conditions (air flow rate, environmental cleanliness, duration of use, etc.). Generally, the recommended replacement cycle for medical ventilator gas filter boxes is after single patient use (disposable models) or every 24-72 hours (reusable models); in home ventilator scenarios, it is usually 1-3 months. We can provide lifetime testing data and clear replacement guidelines based on customer device parameters and regulatory requirements of the target market, assisting customers in formulating after-sales consumables plans.

The standard MOQ for products is usually 1000pcs, and the MOQ for customized products is assessed separately according to the mold and filter material configuration. As for samples: standard samples can be shipped within 3-5 working days; custom samples (involving mold opening) generally take 15-30 days to complete. The bulk delivery period is usually 25-35 days after the order confirmation, and urgent orders can be prioritized in the clean workshop. We have a sufficient inventory of raw materials at our head office in Zhongshan, allowing us to provide VMI inventory management services for long-term cooperative customers, shortening the replenishment cycle.

For medical gas filter boxes, we complete assembly, testing, and initial packaging in GMP clean workshops, using medical-grade PE bags for independent sealing, followed by inner box and export carton packaging that complies with ISTA transportation testing standards. For products with sterilization requirements, we can provide EO ethylene oxide sterilization services along with sterilization verification reports. Every batch of shipments undergoes air-tightness random sampling inspections and full appearance inspections, and we support customer-specified third-party inspections (SGS, BV, TÜV, etc.) to ensure products are delivered to end customers in the best condition.
