HVAC air filters in Minnesota, delivered to your job site
Minnesota’s commercial air quality picture changed permanently in 2021. That summer, wildfire smoke pushed the state’s Air Quality Index above 200 for the first time, reaching purple and maroon categories that present health risks for everyone — not just sensitive groups. Since then, Minnesota has issued air quality alerts at a rate that makes wildfire smoke preparation a year-round operational consideration for commercial facilities, not a seasonal afterthought.
Brookaire operates from Lakeville, MN, 25 miles south of Minneapolis. From there, filters reach job sites across the Twin Cities metro, Rochester, Duluth, Bloomington, and Saint Cloud with scheduled delivery and same-day options. Every order includes job tagging, real-time tracking, and proof of delivery.
Air quality in Minnesota
What the data shows
Minnesota’s air quality has improved steadily on most industrial and vehicle emission metrics over the past 30 years. The MPCA’s 2025 legislative report confirms that conventional pollutants from transportation and manufacturing continue to decline. What the same report confirms is that wildfire smoke and ozone are moving in the opposite direction, with both increasing in frequency and severity over the same period.
The wildfire smoke turning point
Minnesota issued 7 orange AQI alerts in 2018. In 2023, that number was 37 orange alerts and 12 red alerts — a five-fold increase in five years. Of the 52 total air quality alert days in 2023, 16 were directly caused by fine particles from wildfire smoke, with nine reaching the red category (unhealthy for everyone). In summer 2021, wildfire smoke from Canada and the Pacific Northwest pushed Minnesota’s AQI above 200 for the first time in recorded history.

IQAir recorded real-time PM2.5 concentrations placing Minneapolis temporarily among the top 10 most polluted major cities in the United States during those events. These are not rare outliers. The MPCA now treats recurring wildfire smoke events as a structural planning assumption, not an anomaly.

The American Lung Association’s 2025 State of the Air report gave the Twin Cities a failing grade for ozone, ranking the Minneapolis-St. Paul metro 48th worst out of 228 measured metros — a significant decline from 79th worst in the prior year’s report. Anoka County received the metro’s worst grade. The state’s 2025 air quality forecast predicted a moderately active ozone season with 2 to 4 alert days above the yearly average, concentrated in the suburban Twin Cities and Rochester metro areas.

Minneapolis averaged 7.6 µg/m³ PM2.5 in 2024 — below EPA’s standard of 9 µg/m³ in normal conditions. The real concern is the distribution. On the 268 moderate AQI days that PA cities also experience, Minnesota sees similar patterns. But during wildfire events, Minneapolis PM2.5 spikes from a baseline of 7 to 8 µg/m³ to concentrations that can reach 150 µg/m³ within hours. Buildings with MERV 8 filtration provide essentially no meaningful protection during a spike of that magnitude. MERV 13 captures 75 to 95 percent of PM2.5 at normal concentrations and still provides meaningful protection during moderate smoke events. HEPA filtration is the only filter standard that provides near-complete protection across the full spike range.

Minnesota’s medical device cluster: A high-HEPA market
Minnesota’s bioscience sector includes 3,380 establishments and more than 500 medical device businesses employing 34,400 workers. Medtronic, which traces its founding to Minneapolis in the 1950s and maintains its operational headquarters in Fridley, and Boston Scientific both operate facilities requiring ISO-classified cleanrooms and HEPA terminal filtration. Mayo Clinic’s $5 billion renovation and expansion announced for Rochester is the largest single capital project in recent Minnesota economic development history and will require sustained high-specification HVAC supply for years of construction and commissioning.

Frequently asked questions
HVAC air filters in Minnesota
MERV 13 is the standard for all Twin Cities, Rochester, and Duluth commercial buildings. The Minneapolis-St. Paul metro received a failing ozone grade in 2025. During wildfire smoke events — which now occur multiple times per year in Minnesota — MERV 13 captures 75 to 95 percent of PM2.5 particles. HEPA is required for medical device cleanrooms, surgical suites, data centers, and pharmaceutical environments. Call Brookaire to confirm for your specific system.
MERV 13 minimum. In 2023, Minnesota recorded 52 air quality alert days, 16 from wildfire smoke, with 9 reaching red AQI (unhealthy for everyone). Buildings with MERV 8 or lower provide essentially no meaningful PM2.5 protection during a significant smoke event. MERV 13 provides meaningful protection during moderate events. HEPA provides near-complete protection and is recommended for healthcare, medical device manufacturing, and data centers.
