- FFP3 Protection
- Disposable (Non Reusable “NR”)
- Same Fit - Both are 3M “Aura” Design, therefore fit is the same.
- 1863+ is Type IIR Fluid Resistant (EN 14683 Classification)
- 9330+ is not Type IIR Fluid Resistant
See below BSI EU Type Examination excerpts below for further evidence:
Blue = 3M 9330+
Red = 3M 1863+
What does Type IIR mean?
EN 14683 certification is specifically designed for face masks that can protect the wearer from droplets of the people in their vicinity.
Type IIR = bacteria filtering effectiveness > 98% and are splash-resistant (kPa ≥ 16.0)
Why might this matter?
The clinical setting you find yourself in may be of importance.
e.g) If you are a dentist carrying out dental work on a patient, there is a chance that fluid could leave the patients mouth and land on your mask.
If this mask is not Type IIR certified, the mask could become compromised and therefore no longer offer full protection.
