Got to say after figuring this out I am tempted to ditch the western style mattress and replace it with something like a Japanese futon. I assume it'd be much easier to wash.
In the meantime I need to purchase a mattress encasement, I put one on my pillow and that alone helped a bunch.
Long term maybe desensitization is an option but I'm too lazy for that atm.
I did a desensitization and it helped a little bit. Despite the regular washing and using a dust mite vacuum I'm still having a hard time getting good sleep though. At least my nose isn't bloody in the morning anymore, so I guess that's something.
