It operates at 1040 CFM airflow and delivers 40 percent efficiency at full load, making it suitable for jobsite air-cleaning applications where coarse particulate is present. At 2 inches thick, this filter provides mechanical pre-filtration that extends the service life of downstream primary filters. Four prefilters are required per unit installation. Licensed contractors and restoration professionals handling dust, debris, and airborne particulate in contained work areas are the primary installers of this filter type.\u003c\/p\u003e\n\u003cp\u003eThis prefilter is specifically rated for use with ACE portable air scrubber units 73-601 and 73-801. It is commonly installed in commercial and residential restoration, remediation, and construction environments where portable negative-air or air-scrubbing equipment is deployed. The prefilter stage captures larger particles before they reach the primary or HEPA filter stage, reducing change-out frequency on higher-cost filter media. Sold in a package quantity of six, this SKU supports stocking for multi-unit deployments or routine scheduled maintenance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1040 CFM rated airflow matches ACE 73-601 and 73-801 portable air scrubber units\u003c\/li\u003e\n  \u003cli\u003e40 percent filtration efficiency at full load for coarse particulate capture\u003c\/li\u003e\n  \u003cli\u003e2-inch overall thickness for mechanical pre-filtration stage\u003c\/li\u003e\n  \u003cli\u003eFour filters required per unit, protecting downstream primary filter media\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of six to support scheduled maintenance and multi-unit inventories\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ACE portable air scrubber units 73-601 and 73-801.

Four prefilters must be installed per unit  -  do not operate the unit with fewer than the required number of filters in place. Follow the equipment manufacturer service interval recommendations and inspect prefilters regularly in high-particulate environments. Restoration technicians and IAQ contractors typically perform this service as part of routine equipment maintenance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Flow\u003c\/strong\u003e: 1040 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEfficiency at Full Load\u003c\/strong\u003e: 40 percent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.88 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Prefilter (4 required per unit)\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: ACE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 91-955-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACE","offers":[{"title":"Default Title","offer_id":67910981321010,"sku":"91-955-6","price":269.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60eace558ba18b1cb262a48f5fa959ce.jpg?v=1791202546","url":"https:\/\/voomisupply.com\/products\/ace-91-955-6-air-scrubber-prefilter-1040-cfm","provider":"Voomi Supply","version":"1.0","type":"link"}
