Only surgical masks can protect against infection, but because of the measures taken to limit contamination with Covid-19, mouth masks made from organic cotton fabrics are a good alternative. Keep in mind that these mouth masks do not protect you against Covid-19 contamination, but you can protects others by wearing one, as fewer particles are transmitted to the air. Also, by wearing a mask, you remind others to be careful.
Organic cotton fabrics are the best option because they can be washed at 60 degrees Celsius and do not cause allergies or skin discomfort. We recommend using poplin in combination with hydrophilic and the use of a flannel or non-woven interlining for the filter. Twill fabrics are also suitable. Twill is slightly thicker than poplin making it the most recommended option. The tighter weave creates a greater barrier. Therefore, only one layer of twill is needed for the mask. If you prefer to use thinner fabrics, the poplin option is perfect for sewing a double layer mask in which you can insert a filter.
Poplin and flanel are sold in the Bo Weevil onlinestore; for twill fabrics, such as gabardine, we refer to our partner Pure Fabricz for companies or Pure Coverz for consumers.
For those who want to buy ready-made face masks, we refer to companies that work with organic materials:
