MERV 11 Pleated Air Filters

Brookaire's pleated MERV 11 air filter is widely used in commercial and high-end residential HVAC systems. Each MERV 11 filter is manufactured using wire-backed synthetic media assembled within a sturdy cardboard frame, available in 1", 2" and 4" depths across 50+ standard die-cut sizes. The pleated design provides increased media surface area, maximizing airflow efficiency while delivering superior particle capture compared to standard MERV 8 air filters.

MERV 11 pleated air filters are the ideal choice when MERV 13 is too restrictive for your system's airflow capacity but higher-grade filtration is required — capturing Legionella, humidifier dust, lead dust, milled flour, auto emission particles, nebulizer drops, and more. All filters are made in the USA. Bulk pricing available with same or next-day delivery. Need a custom size? We make any size within 48 hours.
