The PopUP™ media replacement filter for media air cleaner systems requires no assembly and pops up ready to use. The collapsible design allows for compact storage and eliminates the need for extra combs, pleat spacers, and end caps. It offers an additional 1 inch of filtration depth compared to standard cartridge replacement filters, the manufacturer claims. Rated at MERV 11, six universal sizes are available. The filters meet the American Lung Association® Health House® guidelines.
