Moisture and heat exchanger

The utility model relates to the field of medical devices, in particular to a moisture and heat exchanger. The moisture and heat exchanger is long in service life, and easy and convenient to manufacture. The moisture and heat exchanger is composed of an upper shell, a lower shell and a filtering membrane component; the upper shell is connected with the lower shell through a buckle to be a whole, and a cavity is formed through the connection of the upper shell and the lower shell; the filtering membrane component is arranged between the upper shell and the lower shell, the centers of the upper shell, the lower shell and the filtering membrane component are on the same axis, two separating cavities are formed through the filtering membrane component, the face, opposite to the upper shell, of the filtering membrane component is hydrophobic membrane materials, and the face, opposite to the lower shell, of the filtering membrane component is hydrophilic membrane materials. Accordingly, the moisture and heat exchanger has the advantages of being simple in structure, convenient to use and reasonable in design and the like.
