The single biggest reason to consider these filters is the \u003cstrong\u003eMERV 13\u003c\/strong\u003e rating, which captures more airborne particles than lower-rated options while still fitting common one-inch filter slots; the pack is sold as a set of four and is fully manufactured in the United States.
