Heat Moisture Exchange Filter System
Heat–Moisture Exchange (HME) filter systems are compact, passive devices designed to conserve a patient’s exhaled heat and humidity and to filter airborne pathogens during mechanical ventilation or tracheostomy care. By capturing moisture and warmth from exhaled gases and returning them to the inspired gases, HMEs help maintain optimal airway conditions, reduce the risk of mucosal drying, and lower infection rates. These systems are particularly valuable in intensive care units, during intra-hospital transport, and for long-term ventilator-dependent patients.
