Directly from the manufacturer in bulk or from bulk deals I see on social media. I can’t mention the brands without having bad opsec sorry. I have my cost down to around $1 per mask and wear them for around 20-40 hours before using a new one (I go by appearance, the fibers start to get soft).
Mask blocs are great and do this kind of thing all the time. Get involved with your local one!
