Product Reviews

3M FF-402 is the medium-size flagship of the Ultimate FX FF-400 series: APF 50, soft silicone seal, ~85% panoramic lens, every 3M bayonet cartridge. Covers long-shift performance, QNFT, cost of ownership, and comparisons to the 6800 Medium, 7800S-M, and FF-401/FF-403 siblings. Default full-face pick for most U.S. adults.

3M FF-403 Ultimate FX full-face respirator review (2026) — large size, APF 50, silicone seal, ~85% panoramic lens. Covers performance vs the 6900 Large, cartridge compatibility, and the most overlooked point in large-respirator selection: fit testing is required before purchase. Do not self-select large without QNFT confirmation.

The 3M FF-401 Ultimate FX is a small-size silicone full-facepiece respirator rated APF 50. Its integrated low-profile harness, wide-view polycarbonate lens, and silicone sealing flange make it the top pick for workers in spray painting, chemical processing, and asbestos programs needing reliable fit on small facial profiles.
