U.S.-based Blinds Chalet has some tips to cut down on household dust:
Real wood blinds, faux wood blinds and aluminum blinds don’t accumulate dust mites like fabric blinds do.
Make your own dust repellent with a mix of one part liquid fabric softener and four parts water. Spray onto a cloth and lightly wipe onto faux wood and aluminum blinds. For real wood, test a hidden location first.
