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.

A study conducted by the US National Institute of Standards and Technology (NIST) states that cotton fabric masks, which are slightly moistened by breath, are more effective than those made of other materials in preventing the spread of infection. pandemic.

Breath-moistened cotton cloth masks capture up to 33% more particles , making them a better choice than synthetic masks to stop the spread of COVID-19.

"Cotton fabrics work in face masks better than we think" ( Christopher Zangmeister, NIST researcher ) Feel free to take a look at the links. At Rewinder , designers and manufacturers of reusable organic cotton hygienic masks, we are convinced that news like this should be a boost for healthy citizens to opt for a reusable option made from a natural material, as is the case with cotton. Faced with the need for protection, the ideal is that it not only protect people but that we try to protect ourselves does not imply the danger and destruction of natural ecosystems and the uncontrolled dumping of plastic waste into the sea.
