The sheet construction uses activated carbon material to trap airborne particles and adsorb odor-causing molecules within its porous structure. This type of media is commonly installed upstream of primary filtration systems to extend filter life and reduce odor load before air reaches downstream components. HVAC technicians and air quality professionals handle installation in residential and light commercial systems.\u003c\/p\u003e\u003cp\u003eThe w4-0855 prefilter blanket suits applications where a flexible, sheet-form carbon media is needed. It is appropriate for use in air handlers, fan coil units, and custom filter housings that require cut-to-fit media. The blanket format allows it to be sized and trimmed to fit a range of enclosures, making it a practical choice for retrofits and maintenance replacements in existing filtration setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eActivated carbon construction adsorbs odor-causing molecules from the airstream\u003c\/li\u003e\n\u003cli\u003eSheet blanket format allows cut-to-fit installation in various housing sizes\u003c\/li\u003e\n\u003cli\u003eCaptures airborne particulates as a prefilter stage, protecting downstream media\u003c\/li\u003e\n\u003cli\u003eFlexible material accommodates curved or irregular filter frames\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement prefilter blanket for air handlers, fan coil units, and custom filter housings that accept sheet-form carbon filtration media.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by HVAC technicians during routine filter maintenance. Always shut down the air handling unit and confirm power is off before accessing the filter compartment. Trim the blanket to the required dimensions using clean shears or a utility knife, and seat the media securely to prevent bypass around the edges. Follow local mechanical codes and the equipment manufacturer's guidelines for filter media replacement intervals.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedia Type\u003c\/strong\u003e: Activated carbon blanket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Stage\u003c\/strong\u003e: Prefilter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MJ BRUNIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: w4-0855\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MJ BRUNIN","offers":[{"title":"Default Title","offer_id":51138599387442,"sku":"W4-0855","price":29.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305533171.jpg?v=1778259837","url":"https:\/\/voomisupply.com\/products\/mj-brunin-w4-0855-carbon-prefilter-blanket","provider":"Voomi Supply","version":"1.0","type":"link"}
