I'd like to buy 20x20x1 size filters for this deal but none of the options for this filter type are accepted for this filter size. Please let me know which option to choose for the 3M 1,000 microparticle performance rating: 12 filters (3M098028)â€”Attracts and captures airborne allergens like pollen, mold spores, dust mite debris, smoke, pet dander, household dust, and smog. Thanks.

I am sorry but we no longer have 20x20x1 filters available. They have all sold out.
