33% higher efficiency of cotton masks compared to other materials
Numerous media have echoed this new study, including NIUS, which has just published with this headline:
Breath moisture increases the effectiveness of cotton fabric masks against covid-19
Today we share the article published this past March 10 by NIUS here.We advance part of its content, which we consider especially relevant, especially in order to promote the use of reusable cloth masks against the excessive use of single-use masks, which is invading the planet with waste by leaps and bounds, during the attempt to protect ourselves against the spread of the pandemic. Some of these relevant data are:
- Cotton fabrics become better filters when exposed to humid conditions. Synthetic fabrics do not. In other words, polyester masks, for example, would not have this filtration capacity.
- Protection against the virus increases up to 33% if the mask is wet, according to the study.
- Surgical and KN95 masks demonstrated the same efficacy in high or low humidity conditions.
