Also check fit carefully if your furnace uses a bottom return style box or nonstandard frames, since actual size variance matters more with 4 in and 5 in depth filters.\u003c\/p\u003e\n\u003ch2\u003ePros \u0026amp; Cons\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003ePros\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003eGood balance of dust capture and airflow from a \u003cstrong\u003eMERV 8\u003c\/strong\u003e pleated media.\u003c\/li\u003e\n \u003cli\u003eFused carbon layer reduces common household odors such as pet and cooking smells.\u003c\/li\u003e\n \u003cli\u003eActual size clearly listed to prevent fit surprises and made to replace specific Lennox models.\u003c\/li\u003e\n \u003cli\u003eTwo-pack offers convenience and value for routine replacements.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCons\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003eActual size differs from nominal size, so customers must measure to ensure a proper fit.\u003c\/li\u003e\n \u003cli\u003eNot designed for very high filtration needs where a higher MERV or HEPA solution is required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n \u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eNordic Pure\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eNominal size\u003c\/td\u003e\n\u003ctd\u003e20 x 25 x 5 in\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eActual size\u003c\/td\u003e\n\u003ctd\u003e19 3\/4 x 24 3\/4 x 4 3\/8 in\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eMERV rating\u003c\/td\u003e\n\u003ctd\u003eMERV 8 (equivalent to MPR 800)\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eReplaces\u003c\/td\u003e\n\u003ctd\u003eLennox X6673, X6675\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003ePack quantity\u003c\/td\u003e\n\u003ctd\u003e2 filters\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eCountry of manufacture\u003c\/td\u003e\n\u003ctd\u003eMade in the USA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eOur Verdict\u003c\/h2\u003e\n\u003cp\u003eThe Nordic Pure 20x25x5 MERV 8 plus carbon two pack is a sensible, value-oriented choice for homeowners who measure their filter slot and want modest odor reduction along with reliable dust capture.
