PTFE is mechanically 100% Hydrophobic which allows it to be washable up to 40 times unlike standard filters that must be re-sterilized to be reused.
It is very lightweight and cool making it breathable, unlike standard filters that are heavier and build up heat from exhalation.
Washing of the media can only be done when it’s inside the mask's cloth inner/outer layer to keep it from abrasion against heavier garments. The best way is to hand wash in lukewarm soapy water and let air dry and make it reusable. Do not wring or twist the washable mask or filter material. Alternatively, you can use an Insta-Pot and put in ¼” water and place mask on the wire rack. Put on Pressure Cook for a 10-minute cycle. Let pressure down and your mask is ready for a new cycle.
Note this filter is not intended for clinical use nor does it guarantee to prevent covid19.
The CDC has adopted a safety-first policy and is recommending everyone wear non-medical protective face coverings to help flatten the curve. Despite this remember this SHOULD be used in addition to practicing CDC recommendations on handwashing and social distancing.
For sanitary reasons, filters cannot be returned.
