Abstract: Embodiments relate generally to a filter (110), 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 (110). Embodiments typically comprise a dustproof membrane (114) and a waterproof membrane (113). Some embodiments may also comprise a splash-proof cap (130) and/or features to reduce negative pressure on the filter (110).
