I like how these posts were written so they can be read to mean opposing things at the same time, and how they're written in such a way that makes the reader assume the posts were written by someone with a poor English skills, making it uncertain what exactly the author means:
>>11761606> "these don't filter the air out"can mean:
"they don't filter the air coming out from your body"
"they don't filter the air outside the mask"
>>11761643> "they filter only what is coming inside of you, not what is coming outside"can mean:
"they only filter the air that's going into you, not the air going out from your body"
"they only filter the air that's coming from inside you, not the air coming from the outside"
