We think they are great, it's our second time ordering them. Your masks are great as well, they are one of my favourite masks!
Additional Mask Filters - 20 Pack
High quality filters, and service was stellar.
I now have filters, I don’t need to go looking for more or worry about running out. I love my mask, it is very comfortable.
I am happy with my masks, filters and nose wires. I do not need any more supplies.
Exceptional masks. Proper weight and fit.
