HEPA filter insert for masks

HEPA filter insert for masks

For use with the 100% cotton masks available in my shop.


Removeable HEPA filter inserts are shown to effectively capture and trap ultrafine virus particles as small as 0.01 microns. (The virus that causes COVID-19 is much larger at approximately 0.125 microns in diameter - so, no problem for HEPA filters).


For highest efficacy, once a filter is used, it should be removed from the mask and set aside in a sealed plastic bag for at least 3 days - to allow any trapped viral particles to die before using again.



    Masks and filters are not designed or intended to prevent, mitigate, treat, diagnose or cure any disease or health condition, including COVID-19/Coronavirus. Masks and filters are intended for general public use only. They are non-sterile and are not intended for use in any clinical or surgical setting or where exposure to bodily or hazardous fluids may be expected, where the risk of exposure through inhalation is high, or near intense heat or flammable gas. Masks are not surgical masks, personal protective equipment, or filtering respirators (such as N95 masks). ANY MEDICAL QUESTIONS SHOULD BE DIRECTED TO YOUR HEALTHCARE PROVIDER. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PRODUCT IS WITH THE BUYER.
