Industry Pain Points

The medical and life science sector is directly linked to patient safety and pharmaceutical quality, imposing extremely strict requirements on filter elements in terms of cleanliness, biosafety, traceability and reliability.

Nosocomial infection control serves as a core indicator of medical quality management. If airborne microorganisms (bacteria, fungi, viruses) in operating rooms, ICUs, transplant wards and burn wards fail to be effectively controlled, the risk of postoperative infections among patients will rise sharply, especially for critically ill patients with compromised immunity.

Pharmaceutical production, particularly sterile preparations, must comply with stringent GMP (Good Manufacturing Practice) standards for cleanroom environments. Class A zones (high-risk operation areas such as sterile filling workshops) need to meet ISO Class 5 (Class 100) cleanliness standards: the permitted count of particles ≥0.5 μm shall not exceed 3,520 per cubic meter, while zero particles ≥5 μm are allowed. Terminal sterile filtration requires filter elements to achieve a bacterial retention rate of no less than 99.9999% against Brevundimonas diminuta.

For respiratory support equipment including ventilators, anesthesia machines and high-flow oxygen therapy devices, inadequate filtration by terminal filters may lead to internal gas circuit contamination by pathogens carried in patient-exhaled aerosols, resulting in cross-infections.

Insufficient intake filtration in oxygen generators and medical air compressors allows oil mist, solid particles and moisture in compressed air to contaminate molecular sieves. This reduces oxygen production purity and may even deliver oil-laden air to patients.

Solutions & Applications

Medical Gas and Equipment Filtration

We provide full-path graded filtration solutions from air intake to terminal ends for oxygen concentrators, ventilators, anesthesia machines and other medical devices, covering oil & water removal, bacterial and viral interception (HEPA grade with filtration efficiency ≥99.995%), and odor adsorption.

Biosafety and Laboratory Protection

ULPA ultra-high-efficiency filters are configured for biosafety cabinets, cell therapy isolators and gene sequencers to achieve ultimate interception of nano-scale particles and microorganisms.

Cleanroom Environment Control

We supply a full range of cleanroom filters including pre-filters, medium-efficiency filters and high-efficiency filters to precisely maintain air cleanliness levels from ISO Class 5 to ISO Class 8 for operating rooms, ICUs, GMP pharmaceutical workshops and biological laboratories.
