3M Secure Click D3076HF P95 + Hydrogen Fluoride Filter

3M Secure Click D3076HF P95 + Hydrogen Fluoride Filter overview

The 3M Secure Click D3076HF P95 + Hydrogen Fluoride Filter is a NIOSH-approved P95 particulate filter that carries its own dedicated hydrogen fluoride (HF) rating — 3M's official name for it is the "P95/Hydrogen Fluoride w/ Nuisance Acid Gas Relief" cartridge. It's tested and rated for HF gas up to 10 times the OSHA permissible exposure limit (PEL) on a half-mask Secure Click facepiece, the standard protection-factor ceiling that applies to any air-purifying cartridge on a half mask. It uses 3M's Secure Click push-to-connect mount and seats with an audible click on 3M HF-800 half-facepiece and FF-800 full-facepiece respirators — it will not fit any 3M bayonet respirator. See our respirator filter types explained guide and the 3M filter and cartridge guide to confirm your exposure before ordering.

Beyond hydrogen fluoride, the D3076HF also provides nuisance-level relief for other acid gases such as chlorine, hydrogen chloride, and sulfur dioxide — relief from odor and irritation at concentrations below their own PEL, not a rated acid-gas cartridge for those gases; browse the nuisance-relief respirators collection for the broader category. For P100 particulate efficiency with the same HF gas rating in a hard polycarbonate case, step up to the 3M D9093C. For general particulate work with no HF exposure, the D3071 or D3078 cost less.

Where it fits

Identify your hazard before choosing any filter — ideally through an industrial-hygiene assessment. Reach for the D3076HF in semiconductor wet-bench HF processes, fluoropolymer processing, and HF acid cleaning where hydrogen fluoride exposure is confirmed at or below 10x the PEL and P95 efficiency meets your standard. For P100 efficiency or a hard-case filter in the same HF work, the 3M D9093C is the upgrade, and the 3M D3096 covers P100 particulate with nuisance acid gas relief when HF specifically isn't present. If your process generates other gases above nuisance levels, step to a matched combination cartridge from the how to choose a respirator cartridge guide.

Frequently asked questions

What is the 3M Secure Click D3076HF used for?

P95 particulate protection plus a dedicated hydrogen fluoride gas rating (up to 10x PEL) and nuisance acid gas relief, on 3M Secure Click HF-800 and FF-800 respirators — common in semiconductor wet-bench HF processes, fluoropolymer processing, and HF acid work.

Does the D3076HF protect against hydrogen fluoride gas, or only mist?

It's NIOSH-tested and rated for hydrogen fluoride gas specifically, up to 10 times the OSHA PEL on a half-mask Secure Click facepiece — the standard half-mask protection-factor ceiling. It is not rated for HF concentrations above that limit or for atmospheres immediately dangerous to life or health.

What does "nuisance acid gas relief" mean on the D3076HF?

It's supplemental relief from odor and irritation caused by other acid gases — chlorine, hydrogen chloride, sulfur dioxide, and similar — at concentrations below their own OSHA PEL. It is not a rated acid-gas cartridge for those other gases and should not be relied on above nuisance levels.

What respirators does the D3076HF fit?

Only the 3M Secure Click platform: HF-800 series half-facepieces and FF-800 series full facepieces. It does not fit any 3M bayonet respirator, including the 6000, 6500QL, 7500, 7800S, or FF-400 series.

What's the difference between the D3076HF and the D9093C?

The D3076HF is P95 with a soft filter housing. The D9093C is P100 (higher particulate efficiency) with a hard polycarbonate case. Both carry the same dedicated hydrogen fluoride gas rating and Secure Click mount; choose the D9093C when your program requires P100 efficiency or a hard-case filter.

Is the D3076HF P95 or P100?

P95 — it captures at least 95% of airborne particles and is oil-proof rated. For P100 (≥99.97%) with the same HF gas rating on Secure Click, the D9093C is the correct filter.

Can I use the D3076HF in an atmosphere immediately dangerous to life or health?

No. The D3076HF is an air-purifying filter, not supplied air. It is not rated for atmospheres immediately dangerous to life or health, sandblasting, or asbestos, and it does not protect against hazardous concentrations of any gas or vapor other than hydrogen fluoride.

Does the D3076HF protect against organic vapor or ammonia?

No. Its only tested gas rating is hydrogen fluoride, plus nuisance-level relief for other acid gases. Organic vapor, ammonia, formaldehyde, and other gas classes require a Secure Click combination cartridge matched to that hazard.

What is the pack quantity for the D3076HF?

Sold as a 1-pair pack — two filters, one for each side of a Secure Click facepiece.

How does the D3076HF compare to the D3071?

Both are Secure Click P95 filters. The D3071 is general particulate only, with no hydrogen fluoride rating, and typically costs less. Buy the D3076HF only when your hazard assessment confirms hydrogen fluoride exposure.

Can I use the D3076HF on the FF-800 full-face respirator?

Yes. The FF-800 is a Secure Click full facepiece, and the D3076HF's push-to-connect mount seats on it the same way it does on the HF-800 half-facepiece.

When should I replace the D3076HF?

Replace it when damaged, soiled, or difficult to breathe through, or per your employer's written respiratory protection program change-out schedule — service life against hydrogen fluoride depends on concentration and exposure time, so don't rely on breathing resistance alone.

Reviewed by Steven Eaton, WC Safety. Specifications reflect 3M's published data for the D3076HF Secure Click filter; hydrogen fluoride exposure limits and respirator selection should follow OSHA 1910.134 and a workplace hazard assessment. Atmospheres above the filter's rated limit, or that are immediately dangerous to life or health, require supplied-air equipment.
