The 3M 6007 is a specialty gas-only cartridge for mercury vapor occurring alongside organic vapor and acid gases like chlorine and sulfur dioxide - no general 3M cartridge covers mercury. This 3M 6007 review covers what it protects against, which 3M respirators it fits, and how it compares to the 6003 and 6006.

A research-intent review of the 3M 7500 Series silicone half mask respirator: all-day comfort, the Cool Flow valve and drop-down design, sizing (7501/7502/7503), compatible 3M bayonet cartridges and P100 filters for painting, welding, woodworking, and chemical work, and how it compares to the 6500 and 6000 series.

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.

3M Secure Click D3078 review: a single-pair P95 particulate filter (95%, oil-resistant) for HF-800 and FF-800 respirators - the same protection as the D3071 in a smaller pack. Particulate only, no gas/vapor. Who needs it, compatibility, limits, and how it compares to the sibling D3071, the D9093 P100, and the D3076HF.

3M Secure Click D7N11 review: an N95 particulate prefilter (20/pack) used ahead of a gas/vapor cartridge to extend its life on HF-800 and FF-800 respirators. It is N95, not oil-resistant, and not P100. What it does, who needs it, compatibility, limits, and how it compares to the D7P71, D3071, and D9093.

The D3097 is a P100 particulate filter with nuisance-level organic vapor relief. The OV relief is below-OEL odor relief only - not a substitute for an organic vapor cartridge such as the D8001 or D80921 where vapor is at or above the limit.

The D9093CB is a P100 particulate filter in a hard case, sold by the case of 144, with nuisance-level acid gas relief. The acid gas relief is below-OEL odor relief only - not a substitute for an acid-gas cartridge at or above the limit.

The D8006 is the broadest gas-only Secure Click cartridge — organic vapor, acid gas, ammonia, methylamine, formaldehyde, no integrated P100. It suits broad gas exposure with no particulate; step up to the combination D80926 when dust or mist is present.

The D8001 is the lightest, most economical Secure Click gas/vapor cartridge — organic vapor only, no integrated P100. It suits vapor-only solvent and paint work; the moment particulate is present, step up to the D80921.

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 D9093 is the standard Secure Click P100 particulate filter in a hard case — silica, mold, welding fume, dust at 99.97%, no retainer. It is a filter only, not a gas/vapor cartridge; the D3091 is the same P100 in standard form.

The D3096 is the standard-form P100 particulate filter with nuisance-level acid gas relief. The acid gas relief is below-OEL odor relief only - not a substitute for an acid-gas cartridge at or above the limit. Same function as the bulk hard-case D9093CB.
