can i put a 3m aura over a kn95?

or would this compromise the seal? wondering bc im reusing a kn95, which has a really good fit, but im worried it won’t be good enough because i’ve already worn it for ~8 hours. i have a 3M aura that i had to staple at the bottom for it to fit me but im unsure if it actually fits because it doesn’t move up and down when i breathe
