Forest fires are going nuts. Any ideas to help me breathe in my bedroom?

All day the smoke has been bad but just in the last hour it is getting much worse. My eyes are all fucked up and my throat is burning.

I have set up a bunch of wet towels on racks with fans blowing on them hoping that will trap the smoke particles. It seems to be helping a bit.

Any other ideas that would help make the air less painful?

And I am somewhat concerned about my fishtank. I am considering shutting off the two air pumps and HOB filter to keep the smoke out of the water. But I am not sure if that will make things worse.
