Here’s some tips I read on creating a clean room at home for doing things like opening and repairing hard drives:

Actually to break the seal on your hard drive, there is a special way . . .

You need a few things

1) saran wrap
2) latex gloves
3) a good box fan
4) a hair net (or hat) and a dust mask (just to keep the drive safe from you)
5) a screw driver to open the drive

Go to your bathroom and turn on the shower for about 10 minutes on hot, so there is lots of steam in there

Then, take the box fan and blow the steam out of the bathroom, this will catch all the particles of dust that hang in the air and blow them with the steam outside of the bathroom, you then take the top of the drive off and IMMEDIATELY wrap it in the saran wrap.

You can then mod the drives top and then put it back together in the “clean room”

It is not guaranteed to work, but I have seen it done with no issues, you just need to wear the right clothes and be super careful.
