Abstract
An anti-fogging facemask for preventing fogging of the wearer's glasses or goggles is described herein. The anti-fogging facemask includes an outer facemask and an inner facemask. The inner facemask is attached to the outer facemask. The inner facemask provides a barrier to prevent exhaled air from traveling through the upper end of the facemask. The inner facemask directs exhaled air downwards. The outer facemask forms a seal at an upper portion of the wearer's nose. The facemask may be configured to serve as a CO2 concentrating mask for temporary relief of allergic rhinitis symptoms.
