    Ultra-Efficiency Pleated Panel Air Filters

    Image of Product. Front orientation. Air Filters. Ultra-Efficiency Pleated Panel Air Filters.
    Capture more viruses and finer allergens than high-efficiency filters—these ultra-efficiency filters can even remove contaminants from wildfire smoke and pollution. They have pleats that create a large surface area for filtering without reducing airflow. The cardboard frame is treated to resist humidity, and the galvanized steel grill prevents sagging.
    While these ultra-efficiency filters may make your HVAC system work harder than lower efficiency filters, they’re still easier on your equipment than HEPA filters.
