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.
