Heat Moisture Exchange Filter （HMEF）
Product Showcase
Information
HMEF is a critical medical device used in respiratory care systems, particularly for patients requiring mechanical ventilation or tracheostomy support. It combines the functions of filtration, heat exchange, and moisture conservation to mimic the natural physiological processes of the upper airway, enhancing patient comfort and respiratory efficiency.Core Functions:
Filtration:
Effectively removes pathogens (including bacteria and viruses) and particulate matter (≥0.3μm particles) from inhaled and exhaled air, with a filtration efficiency of ≥99.99% for particles ≥0.3μm
. This reduces the risk of secondary infections in immunocompromised or critically ill patients.
