American Standard Air Filters come in many sizes. As with all furnace, HVAC and AC filters they are interchangeable with any brand as long as you replace with the same filter size. While we don't carry the American Standard Air Filter brand, we have a large selection of replacement air filters in the same standard sizes that perform just as well if not better. Plus you have several efficiency rating options and can save money with many of the filter options we carry. We only work with leading manufacturers in the indoor air filtration industry for both commercial and residential systems.
Filter sizes can be confusing with nominal and actual sizes. The links below are for replacements in our Exact Filters®. The perfect fit American Standard replacements without being confused by the size of your filter in the future.
