Gerson 1760 N99 Particulate Respirator with Exhalation Valve – Made in USA (Box of 10)

The Gerson 1760 N99 Particulate Respirator combines ≥99% NIOSH-certified filtration efficiency with a premium oversized exhalation valve, addressing the two performance priorities that the 1750 (unvalved) and generic N99 designs leave unmet simultaneously. Manufactured in the United States in Gerson's ISO 9001:2015 certified facility, the 1760 is the high-filtration, high-comfort option in Gerson's particulate respirator line. Each box contains 10 respirators.

Construction and Materials

The 1760 uses Gerson's collapse-resistant double-shell molded cup platform. A soft foam nose cushion creates a comfortable seal at the bridge; the contoured adjustable nose clip reduces eyewear fogging. Smooth latex-free polymer head straps require no pre-stretching and do not catch on hair. The premium oversized valve is engineered to open at lower exhalation pressure than standard valve designs, expelling warm air more readily. Construction is staple-free.

Compliance and Ratings

NIOSH approved for ≥99% filtration efficiency against non-oil-based airborne particles per 42 CFR Part 84. The exhalation valve means the 1760 is not appropriate for surgical environments or where source control (protecting others from the wearer) is required. Meets OSHA 29 CFR 1910.134 for industrial respiratory protection programs specifying N99 performance.

Performance

The valve's oversized geometry and lower opening resistance directly address the heat and humidity accumulation that reduces wearer tolerance of extended N99 wear. In warm industrial environments, the 1760 outperforms the unvalved 1750 in all-shift wear studies. The double-shell construction ensures the filter geometry holds its shape under physical exertion, maintaining consistent face seal and filtration area.

Strengths

• N99 NIOSH certification — ≥99% filtration against non-oil particles
• Premium oversized valve reduces heat and humidity inside the mask
• Collapse-resistant double-shell maintains filter geometry during extended wear
• Latex-free, staple-free construction
• Made in USA — ISO 9001:2015 certified, Middleboro, MA

Limitations

• Exhalation valve passes unfiltered exhaled air — not for surgical or source-control applications
• N-series rating only — oil mist environments require R or P-series protection
• N99 is a less common specification than N95; availability may be more limited during supply chain disruptions

Recommended Use Cases

The 1760 is most appropriate for industrial environments with confirmed N99 requirements where worker comfort during extended wear is a compliance concern. Applications include pharmaceutical manufacturing, fine particulate processing, and high-particulate construction or demolition operations where both elevated filtration and extended wear comfort matter.

Verdict

The Gerson 1760 is the complete solution for programs requiring N99 filtration in a valved format. For organizations where N95 is the governing specification, the Gerson 1740 provides similar valve comfort at a lower cost. For N99 without a valve, the Gerson 1750 is the unvalved alternative.

FAQ

What is the filtration efficiency of the Gerson 1760?

≥99% against non-oil-based airborne particles at the most penetrating particle size, per NIOSH 42 CFR Part 84 testing protocol. This makes it an N99 certified respirator.

How does the Gerson 1760 valve compare to a standard valve?

Gerson's premium oversized valve is specifically engineered to open at lower exhalation pressure than standard valve designs. This means more exhaled air exits through the valve (rather than through the filter media), resulting in a cooler, drier interior during extended wear.

What is the box and case quantity for the Gerson 1760?

Each box contains 10 respirators. A standard case contains 10 boxes for 100 units total.

Can the Gerson 1760 be used in healthcare settings?

The 1760's exhalation valve means exhaled air is not filtered, making it unsuitable for surgical environments where source control is required. For healthcare N99 applications requiring source control, an unvalved design such as the Gerson 1750 is the appropriate choice.

Is N99 significantly better than N95 for practical industrial use?

N99 reduces filter penetration by approximately 80% relative to N95 — from 5% to 1%. In most standard industrial environments where the N95 assigned protection factor of 10 is adequate for measured concentrations, the additional filtration margin of N99 provides no regulatory benefit. N99 is primarily warranted where hazard assessments show concentrations near or above the N95 APF, or where an industrial hygienist has specifically called for the higher rating.
