The 755 A1P2 NR combination filter is designed for use against certain organic gases and vapors with a boiling point above 65°C. It incorporates a non-reusable (NR) filter for liquid or solid aerosols, which attaches to the gas filter via a retaining ring. This particle filter is removable, allowing it to be replaced at the end of its useful life. The combination filter has a non-standard thread for compatibility with Climax masks models 755, 756, and 810.

The P2 NR particle filter consists of several layers of non-woven fabric specially designed to
offer maximum filtration efficiency for both solid and liquid particles. The particle filter is
positioned on top of the gas filter cover and secured with the retaining ring.
