As an accessory and in combination to a smoking instrument such as a traditional cigarette, a personal air filter filtering exhale and intermittent smoke emissions, is disclosed. The device is broadly a housing providing a semi-enclosure having a mouthpiece coupled thereto, the mouthpiece including dual check valve technology for an inhale and a reverse exhale function. Separate or multi-directional filters are provided for the exhale function, and also for filtering intermittent emissions occurring between user intakes. The configuration and filter technology herein, seeks to improve air quality in enclosed spaces, additionally further by minimizing or eliminating second hand smoke.

Various structures for interfaces for a smokable element to connect to a smoke and/or tar filter, and related methods, are provided. For example, the structures and methods enable repeatably and securely connecting or interfacing a smokable element, e.g., an herbal joint, to an air filter, e.g., a smoke and/or tar filter. For instance, an interface can have a horn-shaped end with a deformable opening that receives a smokable element, creating at least a partial seal between the deformable opening of the horn-shaped end and the smokable element. Also, the other end of the interface can have a round end that attaches to an air filter.
