Document Type and Number:
WIPO Patent Application WO/2017/063137
Kind Code:
A1
Abstract:
Systems and methods for reducing moisture inside a face mask. A moisture absorbing system may comprise a jar (110) operable to attach to a face mask (100). The jar (110) may contain a moisture absorbing material (300), such as silica gel beads. The jar (110) may be attached to the mask (100) over an exhalation point, allowing the user's exhaled breath to enter the jar (110), wherein the moisture absorbing material (300) may absorb the moisture from the exhaled breath. The jar (110) may be rechargeable, or reusable. When the moisture absorbing material (300) has been saturated with moisture, the jar (110) may be removed from the mask (100) and heated on a heating base (402) to evaporate the moisture from the moisture absorbing material (300). The moisture absorbing material (300) may change color when it is saturated or dry.
