Abstract
Embodiments relate generally to a filter, for example, for attachment onto a gas detector device or a gas sensor, and attempt to improve the efficiency and service life of the filter. Embodiments typically comprise a dustproof membrane and a waterproof membrane. Some embodiments may also comprise a splash-proof cap and/or features to reduce negative pressure on the filters.
