An in-mouth filtration apparatus, for example for use in sunless liquid-spra y tanning to prevent the inhalation of liquid droplets, particles, and/or toxic gases. Th e filtration apparatus includes a mouthpiece having a curved portion with protrusions for biting upon. This permits the apparatus to be held in place with the jaw in a substantially closed position, thereby reducing the required lip and jaw pressure and improving the comfort and safety of the user. An interchangeable and disposable filtration insert permits airflow only through an end opening which comprises a plurality of holes. A second chamber for receiving such interchangeable inserts may contain additional filtration material.
