Abstract

A heat and moisture exchange filter comprises a layer of hydrophobic media together with a layer of a hydrophilic media. The filter may be used in the medical field in open breathing systems with the hydrophilic material downstream of the patient in the exhalation path. The hydrophobic material prevents the passage of water droplets and globules in known manner and also has a bubble point sufficiently high to trap micro-organisms. The hydrophilic material captures water vapour that passes through the hydrophobic material thereby allowing more moisture to be retained by the filter. This moisture is picked up by the inhaled gases and serves to provide additional humidity for the inhaled gases.
