In modern medical environments, respiratory safety remains a key clinical concern. Whether in intensive care units, during anesthesia and surgery, or in respiratory therapy and mechanical ventilation, effectively filtering pathogens and maintaining airway moisture directly impacts patient treatment outcomes and infection control. Disposable circular HME filter paper is a crucial consumable developed to address this need.

HME stands for Heat and Moisture Exchanger. HME filter paper is the core functional material in HME filters. Its primary function is to recover heat and moisture from the patient's exhaled air and release it again during inhalation, thus mimicking the natural warming and humidifying function of the upper respiratory tract. Simultaneously, it acts as a highly efficient filtration medium, blocking bacteria, viruses, and microparticles.

This disposable circular HME filter paper boasts an absorbency rate of up to 220%, meaning it can quickly absorb and store a large amount of moisture. During exhalation, the filter paper effectively captures moisture; during inhalation, this moisture is released again, effectively preventing airway dryness. This characteristic is particularly important for patients on long-term mechanical ventilation, helping to reduce sputum viscosity, airway damage, and related complications.

Infection control, this HME filter paper also performs exceptionally well. With a filtration efficiency of up to 99.999%, it effectively blocks bacteria, viruses, and particulate contaminants, forming a reliable safety barrier between the patient and the respiratory equipment. This not only helps protect patients from exogenous infections but also prevents contamination of the respiratory circuit, thereby reducing the risk of cross-infection and improving overall medical safety.

The single-use design avoids the problems of incomplete disinfection and performance degradation associated with reuse, meeting the dual requirements of modern hospitals for infection control and operational efficiency. The circular structure also makes it more compatible with various standard HME filters and breathing circuits, simplifying installation and offering flexible use.

This high-performance HME filter paper is widely used in anesthesia machines, ventilators, ICU ventilation systems, emergency respiratory equipment, and other applications, making it an indispensable component of respiratory therapy consumables. For medical device manufacturers, it is also a crucial core material for enhancing the performance and competitiveness of end products.
