What the Gerson 1740 does well
Valve comfort, made in USA
You get heat-venting valve comfort with U.S. manufacturing — relevant for TAA-sensitive buyers who also want the valve. See respirator filter types explained.
Familiar molded cup
Same cup as the 1730, so fit and adoption are straightforward.
NIOSH N95
Genuine 95% non-oil filtration in a domestic product.
Where the Gerson 1740 falls short
No source control
The valve releases unfiltered breath — use the unvalved Gerson 1730 where you must protect others.
Non-oil only
N95 is not oil-rated; use R95 or P100 for oil mist.
Costs more than the 1730
The valve adds cost over the plain cup.

Gerson 1740 FAQ
Gerson 1740 vs Gerson 1730 — what is the difference?
The 1740 adds an exhalation valve for cooler breathing; the unvalved 1730 is for source control and lowest cost. Same N95 protection and U.S. manufacturing.
Is the Gerson 1740 made in the USA?
Yes — like the 1730 it is domestically manufactured, relevant for government and TAA-compliant procurement.
Is the Gerson 1740 NIOSH-approved?
Yes — a NIOSH N95 under 42 CFR Part 84, 95% minimum non-oil filtration.
What does the valve on the Gerson 1740 do?
The one-way exhalation valve vents warm, moist exhaled air to reduce heat and fogging; inhaled air is still filtered. It does not change the N95 level.
Can the Gerson 1740 be used for source control?
No — the valve releases unfiltered breath. Use the unvalved Gerson 1730 there.
Does the Gerson 1740 protect against oil?
No — N95 is non-oil; use R95 or P100 for oil mist.
Gerson 1740 vs 3M 8511 — which valved N95?
Both are valved cup N95s; the 1740's edge is U.S. manufacturing, the 8511 adds braided straps and the widest fit-test support. Choose by sourcing vs comfort/infrastructure.
Can you reuse a Gerson 1740?
Single-use with limited reuse when constrained; discard when soiled, damaged, or hard to breathe through. See can you reuse an N95?.

Yes for OSHA-regulated use — medical evaluation, annual fit test, and seal check per OSHA 29 CFR 1910.134.

No — facial hair across the seal fails the fit test; clean-shaven along the seal is required, or use a PAPR.

No fixed hours — replace at end of task or when dirty, damaged, or breathing resistance rises.
