How to get rid of dusty hay?

[Abi :)]

Hey guys, I bought Small Pet Select hay for the first time and bought a 20lb box (just in case we couldn't buy hay in the future because of lockdown restrictions). It is by far the best hay I have ever bought and my bun loves it! But the thing I've noticed it that it can get quite dusty, I try my best to shake the dust off before I give it to her but it still is a bit dusty, and she sneezes a couple of times if it is too dusty, any way I can get rid of the dust? Thanks in advance! <3

I would put some of the hay in a large Rubbermaid container and shake it out. Remove the top hay that is not dusty, and leave the bottom bits.
