1. A breathing protector for a laryngectomized or tracheotomised person, the breathing protector comprising:
a housing including an upper part coupled to a lower part;
a heat and moisture exchanger (HME) and an air filter retained between the upper part and the lower part of the housing;
a closing valve retained inside of the housing and located proximal the air filter and distal the HME;
an opening formed in the upper part of the housing to form a guide rim on an exterior surface of the upper part of the housing;
a closing member separate from the upper part of the housing, with the closing member inserted into the opening and exposed on the exterior surface of the upper part of the housing within the guide rim, with the closing member coupled to the closing valve;
at least one inlet formed through the exterior surface of the upper part of the housing between the closing member and a side wall of the upper part of the housing; and
at least one outlet formed through the lower part of the housing such that air flow, during use, passes into the at least one inlet and out of the at least one outlet and into a trachea of the person;
wherein the closing member is movable within the opening in an axial direction toward the HME to close the air flow between the at least one inlet and the at least one outlet.
