{"title":"Fiberglass Furnace Filters","description":"\u003cp\u003eFiberglass furnace filters are an economical solution designed to capture larger airborne particles and help protect your HVAC system from dust, lint, and debris. Commonly found in residential heating and cooling systems, these disposable filters provide basic filtration while allowing excellent airflow, making them a practical choice for homeowners who prioritize equipment protection and low replacement costs.\u003c\/p\u003e\n\u003cp\u003eUnlike pleated air filters, fiberglass filters typically have a lower MERV rating and are not intended to capture smaller particles such as pollen, pet dander, mold spores, or bacteria. Instead, their primary purpose is to prevent larger contaminants from accumulating on your furnace or air conditioner components, helping maintain reliable system operation and reducing unnecessary wear.\u003c\/p\u003e\n\u003cp\u003eBecause fiberglass filters offer less airflow resistance than higher-efficiency pleated filters, they may be recommended for some older HVAC systems or applications where maximum airflow is preferred. However, homeowners looking to improve indoor air quality, reduce allergens, or capture finer particles may benefit from upgrading to a pleated filter with a higher MERV rating.\u003c\/p\u003e\n\u003cp\u003eFiberglass furnace filters are available in a variety of standard sizes and should be replaced regularly to maintain proper airflow and system performance. Most homeowners should inspect their filter monthly and replace it every 30 days or according to the manufacturer's recommendations, household conditions, and HVAC usage.\u003c\/p\u003e\n\u003cp\u003eWhether you're replacing an existing fiberglass filter or looking for an affordable option to protect your heating and cooling equipment, you'll find a selection of fiberglass furnace filters designed to fit many of today's most common HVAC systems.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is a fiberglass furnace filter?\u003c\/h3\u003e\n\u003cp\u003eA fiberglass furnace filter is a disposable HVAC air filter made from layered fiberglass fibers. Its primary purpose is to protect your heating and cooling equipment by capturing larger airborne particles such as dust, lint, and debris before they enter the system.\u003c\/p\u003e\n\u003ch3\u003eAre fiberglass furnace filters good?\u003c\/h3\u003e\n\u003cp\u003eFiberglass furnace filters are effective at protecting HVAC equipment from larger particles and maintaining strong airflow. However, they provide only basic air filtration and are less effective than pleated filters at capturing allergens, pet dander, pollen, and other fine airborne particles.\u003c\/p\u003e\n\u003ch3\u003eWhat's the difference between fiberglass and pleated furnace filters?\u003c\/h3\u003e\n\u003cp\u003eFiberglass filters use flat layers of spun fiberglass and typically have lower MERV ratings, while pleated filters use folded synthetic media to create more surface area for capturing smaller particles. Pleated filters generally offer better indoor air quality but may create slightly more airflow resistance depending on the MERV rating.\u003c\/p\u003e\n\u003ch3\u003eHow often should I replace a fiberglass furnace filter?\u003c\/h3\u003e\n\u003cp\u003eMost fiberglass furnace filters should be replaced every 30 days. Homes with pets, higher dust levels, or heavy HVAC use may require more frequent replacement. Checking your filter monthly is the best way to ensure proper airflow and system performance.\u003c\/p\u003e\n\u003ch3\u003eCan fiberglass furnace filters help with allergies?\u003c\/h3\u003e\n\u003cp\u003eFiberglass filters are not designed to capture the smaller particles that commonly trigger allergies. Homeowners looking to improve indoor air quality or reduce allergens should consider a pleated furnace filter with a higher MERV rating.\u003c\/p\u003e","products":[{"product_id":"koch-274-120-200-12-x-20-x-1-disposable-dual-density-fiberglass-filter-panel-merv-4-5","title":"Koch 274-120-200 - 12\" x 20\" x 1\" Disposable Dual-Density Fiberglass Filter Panel, MERV 4\/5","description":"\u003cp\u003eKoch 274-120-200 - 12\" x 20\" x 1\" Disposable Dual-Density Fiberglass Filter Panel, \u003cstrong\u003eMERV 4\/5\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli style=\"mso-list: l0 level1 lfo1; tab-stops: list .5in;\" class=\"MsoNormal\" data-mce-style=\"mso-list: l0 level1 lfo1; tab-stops: list .5in;\"\u003e\n\u003cb\u003eNominal Filter Dimensions: \u003c\/b\u003e12x20x1\u003c\/li\u003e\n\u003cli style=\"mso-list: l0 level1 lfo1; tab-stops: list .5in;\" class=\"MsoNormal\" data-mce-style=\"mso-list: l0 level1 lfo1; tab-stops: list .5in;\"\u003e\n\u003cb\u003eActual Filter Dimensions: \u003c\/b\u003e11-1\/2\" x 19-3\/4\" x 3\/4\"\u003c\/li\u003e\n\u003cli\u003eDurable construction for all types of industrial and commercial applications\u003c\/li\u003e\n\u003cli\u003eHeavy-duty frame and corners for added strength and durability\u003c\/li\u003e\n\u003cli\u003eEnvironmentally friendly\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEasy to install\u003c\/li\u003e\n\u003cli\u003eFiberglass Media - Standard C\u0026amp;I Disposables are constructed with high-grade progressively dense glass fibers.
