For allergy sufferers and pet owners the combination of MERV 11 performance and a higher pleat count is the single biggest reason to consider this pack.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversally compatible size:\u003c\/strong\u003e The filters measure 18 x 18 x 1 in nominally and an actual size of 17.75 x 17.75 x 0.75 in, so they fit most residential and commercial return slots and central units.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMERV 11 filtration:\u003c\/strong\u003e Rated to trap finer particles like dust, pet dander and pollen, the filter helps reduce airborne allergens around the home.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced pleated technology:\u003c\/strong\u003e A higher pleat count increases media surface area to improve capture coverage while maintaining airflow through the system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix pack convenience:\u003c\/strong\u003e Supplying multiple replacements at once reduces shopping trips and ensures you can change filters on a three-month cycle without delay.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in USA components:\u003c\/strong\u003e Constructed from American materials with recycled content, offering a domestic manufacturing advantage for shoppers who prefer that origin.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Simply MERV 11 six pack is best for homeowners with pets, mild to moderate allergy sufferers, and small offices or classrooms that need improved indoor air without upgrading to high-resistance filters.
