These filters deliver MERV 11 filtration in a practical 3-pack sized for whole-house replacement, capturing most common allergens and pet dander while fitting in deeper 5 in filter slots (actual size 18.38 in x 28.63 in x 3.69 in). The bottom line: they are a cost-conscious, longer-lasting alternative to basic fiberglass panels and are worth considering for allergy-prone households and pet owners seeking consistent filtration every 90 days.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMERV 11 performance:\u003c\/strong\u003e The synthetic media captures up to 95% of dust, helping reduce pet dander and common allergens without significantly restricting airflow.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrostatic pleated media:\u003c\/strong\u003e Electrostatically charged material with about 8 pleats per ft traps finer particles and extends usable life compared with fiberglass panels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActual sizing:\u003c\/strong\u003e Measured at 18.38 in x 28.63 in x 3.69 in, these filters are sized to fit 20x30x5 housings while making it easy to confirm fit before installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable frame:\u003c\/strong\u003e Beverage board recyclable frames with dual wire backing resist warping and temperature extremes better than thin cardboard options.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in the USA media:\u003c\/strong\u003e The filter media is manufactured domestically, which can provide consistent quality and electrostatic charge performance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe filters are best for homeowners or small businesses with furnaces, air conditioners, or heat pumps that accept 20x30x5 elements and where allergy or pet dander reduction is a priority.
