Designed for residential forced-air systems, this filter goes beyond basic equipment protection by capturing microscopic airborne particles in addition to the larger debris that standard flat-panel filters target. The pleated media increases surface area relative to a fiberglass panel, which supports longer service intervals and consistent airflow resistance. MERV 8 performance makes it appropriate for households with seasonal allergy concerns or where wall and furnishing staining from fine particles is an issue. HVAC technicians and homeowners commonly stock these in case quantities to maintain scheduled filter change programs.\u003c\/p\u003e\u003cp\u003eThe 84858.011825 fits standard 18 x 25 x 1 inch filter slots found in residential furnaces, air handlers, and return-air grilles. The Naturalaire Standard Pleated line is rated under ASHRAE 52.2 at MERV 8, positioning it above basic fiberglass filters while maintaining acceptable static pressure drop across typical residential blower systems. The case pack of 12 is practical for service contractors maintaining multiple units or for building managers on a quarterly filter replacement schedule.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eASHRAE 52.2 rated MERV 8 filtration captures fine particles including allergens and fine dust\u003c\/li\u003e\n\u003cli\u003ePleated media design increases surface area for improved particle capture versus flat-panel filters\u003c\/li\u003e\n\u003cli\u003eNominal size 18 inches x 25 inches x 1 inch fits standard residential filter slots\u003c\/li\u003e\n\u003cli\u003eSold as a case of 12 filters for bulk replacement programs\u003c\/li\u003e\n\u003cli\u003eDrop-in replacement design requires no tools for installation\u003c\/li\u003e\n\u003cli\u003eReduces fine particle buildup on walls, furnishings, and HVAC components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement pleated filter for residential gas furnaces, heat pumps, and air handlers equipped with a standard 18 x 25 x 1 inch filter slot.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFilter replacement is a routine maintenance task performed by HVAC technicians and qualified building maintenance staff. Before replacing the filter, set the thermostat to off and confirm the blower has stopped. Note the airflow direction arrow printed on the filter frame and orient it so the arrow points toward the blower or furnace cabinet, not toward the return duct. MERV 8 filters in high-dust environments should be inspected monthly and replaced at least quarterly to prevent excessive pressure drop across the system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 18 x 25 x 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMERV Rating\u003c\/strong\u003e: 8 (ASHRAE 52.2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12 filters per case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.5 pounds (case)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AAF\/FLANDERS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 84858.011825\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FLANDERS FILTERS","offers":[{"title":"Default Title","offer_id":51525187174706,"sku":"84858.01183","price":115.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40ff5644f9938cbcbbf0103a1f7b1e12_bd82044e-5194-4177-ac38-498acda05dcc.jpg?v=1785466651","url":"https:\/\/voomisupply.com\/products\/aaf-flanders-84858-011825-pleated-air-filter-18x25x1-merv-8","provider":"Voomi Supply","version":"1.0","type":"link"}
