The actual size is 17.5 x 19.5 x 0.75 inches, designed to fit many standard residential HVAC units that use a 1 inch filter slot. The electrostatically charged synthetic media captures a broad range of particles as small as 0.3 to 1.0 microns, including lint, dust mites, mold spores, pollen, pet dander, smoke, and fine dust. The result is a cleaner flow of air through your home and potentially less buildup in the system over time.\u003c\/p\u003e\n\u003cp\u003eIn real world use, you may notice the difference during routine cleaning and daily activities: dust tends to settle less densely on surfaces, allergens can be less noticeable during peak seasons, and the HVAC system works with less resistance thanks to optimized airflow. The pleated construction adds surface area for longer-lasting filtration without restricting air flow, which can help your unit run more efficiently and may reduce maintenance needs.\u003c\/p\u003e\n\n\u003ch3\u003eKey benefits at a glance\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eUniversal compatibility with most 1 inch filter slots, including Carrier, Bryant, Payne and Honeywell.\u003c\/li\u003e\n  \u003cli\u003eHigh efficiency MERV 11 filtration (comparable to MPR 1200 and FPR 7) that traps up to 95% of airborne particles such as dust, pollen, mold spores, pet dander, and smoke.\u003c\/li\u003e\n  \u003cli\u003eOptimized airflow design: media captures fine particles without overly restricting airflow, supporting HVAC efficiency.\u003c\/li\u003e\n  \u003cli\u003eDurable pleated construction with a sturdy frame that resists humidity and temperature changes.\u003c\/li\u003e\n  \u003cli\u003eMade in the USA using quality materials for dependable performance and cleaner indoor air you can trust.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eUsage tips and care\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eChange every 60 to 90 days under typical use; increase frequency to 30 days during peak summer and winter months when the system runs hardest.\u003c\/li\u003e\n  \u003cli\u003eSix filters per pack provide a convenient yearly supply and help maintain consistent filtration.\u003c\/li\u003e\n  \u003cli\u003eCheck compatibility with your furnace or AC unit’s filter slot to ensure a proper fit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWhy choose Aerostar?
