[This review was collected as part of a promotion.] Great USA company to work with. Made my custom filters for a competitive price and shopped them fast for free. Will be back for more when needed.

These look ok but the thickness was too thin being 3.5 inches instead of 4 so I asked if they had 5 inch thickness which would've been 4.5 inches and fit my furnace much better, they indicated they didn't make them that size which was disappointing seeing they made the 5 inch thickness in other sizes but not 25x25. So I'm stuck with a couple that are about an inch too thin.
