that is what i used to usebadgr said:Not worth the risk. Dry sheets are not going to protect against mold spores pet dander or even pollen. They are for making your clothing soft and fresh or packing into the end of a doob tube.
I use Filtrete Room air conditioner filters.
-electrostatically charged fibers
-captures microscopic allergens like dust and smoke particles
-captures large allergens like mold spores, pet dander and pollen
Lasts about 2 months according to the box but I replace ever month. Keeps me and my plants happer. And the filter sheet is certified by the American Lung Association Health House. Good stuff.
Pricey though.
