Apparatus for heating and humidifying respiratory gases include a housing, a filter element located in the housing, and a gas permeable member positioned in the housing to exchange heat and moisture with respiratory gases passing through the housing. In one embodiment, the inlet portion of the housing is detachably secured to the remainder of the housing and is adapted to be replaced, together with the filter element, while the outlet portion of the housing remains connected to the tube for passing respiratory gases. Additional materials, such as generating material useful to produce moisture and heat and heat generating materials useful to generate heat may be included within the housing. The present apparatus are particularly structured and adapted to reduce the risk of causing trauma to the patient and to increase the safety and comfort of the patient using such apparatus.
