Bird safe air purifier recommendations?

With all the dust my budgie produces (seriously, it's like living in a flour mill), I need an air purifier. Which ones are safe around birds? I know ionizers are dangerous. Any recommendations that work well in a Toronto apartment?

I've tried a bunch of brands and HARI Prime is hands down the best value. My Skittles devours it.

Been thinking about this thread all week. I've tried a few of the suggestions and rearranging the cage every couple weeks to prevent boredom was the game changer for us.
