The filtration level for the third embodiments for adults and children of the present invention is 99.8%.
How the Invention is Used
[0040] The invention is used by wearing the headband/ear loops around the ears or the head of the user depending on how they are designed. The back of the mask consisting of the outer layer is pressed firmly around the nose and mouth areas thereby, allowing the user to freely breathe in clean air free from pathogens.
[0041] It's vital to note that for the present invention to be reused while maintaining the effectiveness of its functionality, the user must ensure that it is properly disinfected and washed according to the instructions presented below: [0042] i. For disinfecting: Use a disinfecting spray that is human and textile friendly, sprayed for 2-3 seconds about 30 cm away from the face mask. (Both sides of the mask can be sprayed). [0043] ii. For washing: Soak the mask for 15-30 minutes in lukewarm water with soap, rinse, allow the water to drain off the mask by gently pressing it in its natural folded position, then let it air dry in the shade in an open position and should only be worn when completely dry. The present invention should not be used when not completely dry, should not be squeezed, it should not be tumble dried. Washing the face mask in a machine will damage its filtration effectiveness. Hand wash is most recommended. It is very important to hang and completely air dry in order to eliminate any viruses, bacteria, or other pathogen that may have come into contact with the face mask.
