We have conducted Research into the effectiveness of Facemasks that are not N95/FSP3 certified. In light of the current Covid-19 virus we want people to be safe. We are appalled that some retailers are using the current shortage of FSP3 and N95 masks to profiteer from the most vulnerable in our society. However there is a shortage of these products, and if the products cannot be purchased or located, we need to consider alternative solution.
We are not claiming that our products will save you from the Covid-19 virus, but are happy to share with you the research that we found on the subject of effectiveness of Facemasks that are not N95/FSP3 certified.

An abstract of the report summary reads as follow;
Objective: This study examined non-commercial masks as an alternative to commercial face masks (FSP3 and N95).
Methods: Several household materials were evaluated for the capacity to block bacterial and viral aerosols. Twenty-one healthy volunteers use non-commercial face masks made from cotton; the masks were then tested for fit. The number of microorganisms isolated from coughs of healthy volunteers wearing their non-commercial mask, a surgical mask, or no mask was compared using several air-sampling techniques.
Results: The median-fit factor of the homemade masks was one-half that of the surgical masks. Both masks significantly reduced the number of microorganisms expelled by volunteers, although the surgical mask was 3 times more effective in blocking transmission than the non-commercial mask.
Conclusion: Our findings suggest that a non-commercial mask should only be considered as a last resort to prevent droplet transmission from infected individuals, but it would be better than no protection.
