Please see the enclosed paper of a research study “Comparing 3M N95 and NASK Nanofibre Smart Mask (NIOSH 95 – Professional Edition) before and after nursing procedures (Suen LKP et al., Journal of Hospital Infection, http://doi.org/10.1016/j.jhin.2019.09.014)” for your reference. The paper can be summarized as below:
In the study, mask fitness test and usability satisfaction survey were conducted in order to evaluate the applicability of the nanofiber smart mask, benchmarking with the “best-fitted respirator” including “3M’s 1860 series” and “3M’s 1870 plus”.
104 subjects were involved in the study.
All masks used in the study were N95-certified by NIOSH.
2 major conclusions can be drawn from the study:
The overall fit factor of the nanofiber smart mask is higher than that of the “best-fitted respirator”, no matter whether the fit factors are determined before or after nursing procedures.
The usability (i.e. user satisfaction) of the nanofiber smart mask is significantly higher than that of the “best-fitted respirator” in all investigated aspects including “heat”, “breathability”, “tightness”, “ease in talking”, “mist over glasses”, “itchiness”, “difficulty of maintaining the mask in place” and comfort on ear lobe”.
