Just alright
They are alright. They will work in the masks that I've made. There no indication which side goes out (luckily my friend is an osha's safety officer). The first order never made it to me after several delivery date changes, was given a choice of refund or new shipment, chose refund, got new shipment instead. Live & learn.

Not what I expected
It took a really long time to be delivered. The filters are an odd shape. They are two small for the Olson mask it only covers the mouth part not the nose. I’ve also tried it in the regular masks and it fits weird because it flattens out the creases on the mask when you put the filters in. They don’t work for me.
