Manufactured in the USA and sold as a 4-pack, these 1-inch pleated filters (actual size 13 x 18 x 3\/4 in) aim to extend service life up to 90 days while keeping HVAC airflow largely unaffected.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMERV 13 rating:\u003c\/strong\u003e Captures smaller airborne particles than lower rated filters, improving indoor air quality for sensitive households.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePleated design:\u003c\/strong\u003e More surface area helps trap contaminants while maintaining normal airflow through typical A\/C and furnace systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in USA:\u003c\/strong\u003e Fully manufactured in the United States using consistent materials and construction with EPA establishment information noted.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-pack convenience:\u003c\/strong\u003e Provides multiple replacements so users can change filters on a seasonal schedule without frequent reordering.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplace every 30-90 days:\u003c\/strong\u003e The filters are designed to last up to 90 days with recommendations to check and replace between 30 and 90 days depending on use and conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis product is best for homeowners and renters with forced-air heating and cooling who want a higher-efficiency, pleated 1-inch filter to reduce dust, pollen and other airborne particles.
