This is a two-pack of 3M Filtrete 24 x 24 x 1 pleated furnace filters rated MPR 1900 and MERV 13. That rating puts it among Filtrete's higher-tier filters: it captures fine particles and is marketed for allergens, bacteria and viruses, at the cost of more airflow resistance than a basic filter. The best new price is $41.56 at Walmart as of November 7, 2026, for the two-pack, or about $20.78 per filter.

Filtrete's higher-MPR filters are generally well regarded for allergy relief and dust reduction. Owners of 1-inch systems often note that MERV 13 filters load up quickly and can strain weaker blowers.
