Product Reviews

Verdict: 4.6/5. The 3M Secure Click D3076HF is the specialized P95 filter for HF-800 users facing hydrogen fluoride aerosol exposure - P95 efficiency plus HF sorbent in a single filter body, with the critical caveat that it covers HF aerosol only, not vapor-phase HF.

The D9093C is a P100 particulate filter in a hard case with nuisance-level hydrogen fluoride relief. The HF relief is below-OEL odor relief only - not a substitute for an acid-gas cartridge where HF is at or above the exposure limit.

The 3M 2076HF is a P95 particulate filter with nuisance-level relief for hydrogen fluoride, acid gas and organic vapor - built for semiconductor and HF-adjacent work below the OSHA PEL, not as a gas cartridge. This 3M 2076HF review covers what it protects against, which respirators it fits, and how it compares.

The 3M 60922 is the acid gas + P100 combination cartridge, pairing acid-gas protection with a P100 particulate filter in one bayonet unit. This review covers what it protects against, which 3M 6000, 6500QL, and 7500 respirators it fits, where it falls short, and how it compares to the 6002, 60923 and 60921.
