No degrading results on filtration performance or face-becoming were noticed for the completely different fashions of FFRs tested as all treated masks managed to pass quality and security standards. Lindsley et al. reported that there was a small improve in particle filtration efficiency (up to 1.25%) but little effect on move resistance for many models of FFRs upon present process UVGI therapy with an exposure dose between a hundred and twenty and 950 J/m2 . The elastic strap, however, skilled decreases in breaking strength as the dosage of UV radiation will increase.
