Composed of 防 (to prevent, to guard against) and 塵 (dust). A technical term commonly seen on product labels, safety equipment, and industrial specifications.
USAGE:
防塵 is almost always used attributively — it modifies another noun rather than standing alone as a subject. On consumer electronics it very often appears paired with 防水 (waterproof) as a single compact specification.
COMMON COLLOCATIONS:
- 防塵マスク: dust mask
- 防塵カバー: dust cover
- 防塵仕様: dustproof design / specification
- 防塵性能: dustproof performance
- 防水・防塵: waterproof and dustproof (a set phrase)
SIMILAR WORDS:
- 防水: waterproof — the parallel term for water resistance; the two are often paired
- 耐塵: dust-resistant — a less common variant emphasizing the ability to withstand dust rather than prevent its entry
- 集塵: dust collection — the opposite side of the problem, used for vacuum cleaners and industrial dust collectors
