Use this adaptor to be able to use a PAPR filter at the end of a snorkel mask.
Masks can be found on Amazon, at WalMart, or any local or online retailer.
PAPR filters, to my understanding, are only available to order through healthcare professionals. Please consult with your director/ manager to see if you are able to acquire the filter pictured.
Please check the lead time page for current lead times.
