Functioning as the first stage of filtration, these prefilters extend the service life of the primary electronic cells by intercepting lint, hair, and coarse debris. They are a direct OEM-style replacement and are suited for installation by licensed HVAC technicians performing routine maintenance on residential whole-home air cleaning systems.\u003c\/p\u003e\n\u003cp\u003eThese prefilters are rated for use in residential electronic air cleaner systems.

Each pack includes 2 prefilters, allowing a complete replacement at a single service call.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-pack format covers a complete prefilter replacement in one order\u003c\/li\u003e\n  \u003cli\u003e20 x 20 inch dimensions match OEM sizing for the supported units\u003c\/li\u003e\n  \u003cli\u003eFirst-stage filtration design intercepts large debris before the main collection cells\u003c\/li\u003e\n  \u003cli\u003eHelps extend the service interval and performance of electronic collection cells\u003c\/li\u003e\n  \u003cli\u003eManufactured by Resideo Technologies Inc. for OEM-grade fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with Honeywell F300 and Honeywell F50A, F50B, F50E, and F50F electronic air cleaner systems, as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed HVAC technician. Before servicing the electronic air cleaner, shut off power to the unit at the disconnect or breaker to eliminate shock hazard from the high-voltage ionizing cells. Remove the existing prefilters, inspect the cabinet and collection cells, install the new prefilters in the correct orientation per the unit access door markings, and restore power only after the cabinet is fully closed and latched.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Filter Type\u003c\/strong\u003e: Electronic Air Cleaner Prefilter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer\u003c\/strong\u003e: Resideo Technologies Inc.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RESIDEO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 203373\/u\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RESIDEO","offers":[{"title":"Default Title","offer_id":51138317386034,"sku":"203373\/U","price":59.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305533384.jpg?v=1778253243","url":"https:\/\/voomisupply.com\/products\/resideo-203373-u-electronic-air-cleaner-prefilter-20x20-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
