Abstract
A respirator includes a head unit configured to be received on a human head and a purifying unit configured to provide purified air to the head unit. The purifying unit includes a first housing portion having an interior side defining a blower cavity, an exterior side defining a partial filter chamber with a filter sealing surface, and an inlet hole circumscribed by the sealing surface and extending between the interior and exterior sides. A second housing portion has an interior side defining a blower cavity. The first and second housings are attached to each other to form a housing such that the blower cavities are opposite each other to define a blower chamber within the housing. A blower is disposed in the blower chamber. A filter covers over the inlet hole and is disposed against the sealing surface such that air entering the hole passes through the filter.
