Respirator - Single Filter (NP-305)

A half-mask respirator taking a single filter, model NP-305. It differs from a disposable dust mask in kind rather than degree: the rubber facepiece seals against the skin, and everything breathed in passes through a replaceable filter cartridge rather than through the mask material. That is what makes it suitable for the work a paper mask cannot cover - spray painting and solvent-based coatings, adhesives and thinners, chemical handling, and prolonged exposure to heavy dust where a disposable would clog within the hour. Which filter it takes and what that filter is rated against are not recorded here, and they matter absolutely: a filter for dust gives no protection against solvent vapour. Confirm the filter for your work before relying on it.
