Specifications

Typical Applications

• Fine non-oil dust requiring N99 in warm or active conditions; see all N99/N100s
• Pharmaceutical and high-precision manufacturing with elevated fine-particle hazards

• Read our N95 vs P100 guide to confirm N99 is the right class for your hazard

Hazard Coverage — Gerson 1760 N99 Particulate Respirator with Valve — Box of 10

The Gerson 1760 N99 Particulate Respirator with Valve — Box of 10 is NIOSH-approved under 42 CFR 84 Subpart K as an N99: ≥99% filtration of non-oil particulates — higher than N95 without oil resistance. Appropriate for fine non-oil dust and sub-micron metal fumes where N95 efficiency isn't sufficient. Browse all N99 and N100 respirators.

Not oil-resistant — for oil aerosols use R95 or P100. See our N95 vs P100 comparison.

Frequently Asked Questions

What does the exhalation valve on the 1760 do?

The exhalation valve opens when you breathe out, allowing warm humid air to exit directly rather than passing back through the filter media. This reduces heat and moisture buildup inside the mask — a significant comfort advantage during extended or physically demanding wear. Inhalation closes the valve, so all inhaled air is filtered normally.

Does the valve on the 1760 reduce filtration efficiency?

No. The exhalation valve does not affect inhalation filtration efficiency — the 1760 still filters inhaled air at the rated N95/R95/P100 level. The valve only controls exhaled air routing. Note: because exhaled air is not filtered, valved respirators are not appropriate as source-control devices (e.g., in surgical environments or when protecting others from the wearer).

Is a valved respirator like the 1760 acceptable for source control?

No. A valved respirator directs exhaled air outward unfiltered and is not appropriate where the wearer must also protect others (surgical settings, some healthcare environments). Facility policies may prohibit valved masks in sterile or at-risk patient areas. For source-control requirements, use an unvalved N95 or a surgical N95.

What does N99 mean for the 1760?

N99 indicates NIOSH approval for ≥99% filtration of non-oil-based particles — higher than the N95 standard but without oil resistance. The 1760 is appropriate when N95's 95% efficiency isn't enough for fine non-oil particulates. Browse all N99 and N100 respirators.

How is the 1760 different from an N95?

The 1760 offers 99% filtration vs N95's 95% minimum — useful for finer particles like sub-micron metal fumes, extremely fine dust, or environments where a higher protection factor is desired without stepping up to a reusable half-face respirator. Neither N99 nor N95 provides oil resistance; for oil aerosols, choose R95 or P100.

Is the 1760 NIOSH-approved?

Yes. The 1760 is NIOSH-approved under 42 CFR 84 Subpart K as an N99 filtering facepiece respirator. Confirm the TC approval number on the NIOSH Certified Equipment List.

Does the 1760 require a fit test?

Yes. OSHA 29 CFR 1910.134 requires fit testing before first occupational use. Our fit testing guide covers both qualitative (QLFT) and quantitative (QNFT) protocols. A proper facial seal is essential for rated N99 performance.

Can the 1760 be used in oil mist environments?

No. N99 class respirators are rated for non-oil particulates only. In oil mist environments (spray painting, machining, oil-mist coolants), use an R95 (oil-resistant, one shift) or P100 (oil-proof, no time limit). See our N95 vs P100 comparison guide.

Is the 1760 reusable?

No, the 1760 is a disposable N99 respirator. Discard when soiled, damaged, or when breathing resistance increases. Do not wash or attempt to reconstitute the filter.

What hazards does the 1760 NOT protect against?

The 1760 does not filter gases, vapors, or chemical vapors — only non-oil particulates. For vapor hazards, you need a respirator with chemical cartridges. It also does not protect against oxygen-deficient atmospheres.

How many come in a box?

See the product title for pack count. Browse all N99 and N100 respirators for size options.

What is the shelf life of the 1760?

Typically 5 years from production date in original sealed packaging stored in cool, dry conditions. Check the expiration date on the box.
