These are fashion mask to give u price of mind. They are not medical grade or protect u from the covid19. All mask are interfaced to add a lil more protection. I also leave a split so u can add your own filter. I do not add splits for children mask unless u ask. No extra charge. You can also get $5 mask with no interfacing for a toddler or babies if u like. 

Disclosure. I am not a medical professional and these do not protect you from the covid19
