Indoor air takes more than an AQI. It takes and — and one daily score that holds both, your Lution Level.

Lution is a system that combines sensors, sampling, and accredited laboratory analysis — reading your air continuously, and from a sample that has seen over a million times more air than a spot test.
01 — The Sensors
Installed in your home, Lution's advanced sensors breathe the same air you do — about 40 pounds of it a day. They read how conditions change hour by hour, catching the patterns and shifts a one-off test misses.
02 — Your Filters
Lution uses your home's own filters to sample what's moving through your air. Your filters serve as both filtration and sampling tools, capturing airborne material as it moves through your system — more than a billion liters of air in three months.¹ Using the compact hand vacuum provided, you collect a sample on your own time and send it to an accredited partner laboratory for analysis.

03 — The Lab
Accredited partner laboratories run a battery of tests on your sample — gene-targeted sequencing that identifies mold and bacteria, and microscopy read by laboratory scientists for the materials that make up the rest of your dust.

04 — Your Lution Level
Every morning, the Lution app gives you a Lution Level for yesterday's air: the band, what drove it, and the next thing to do. When something changes during the day, you know what's happening — and what to do about it.
Spore trap: 5 L/min × 5–10 min = 25–50 L. Residential HVAC: 35,000–55,000 L/min, 90 days at 35% runtime = 1.6–2.5 billion liters (55–90 million ft³). Ratio: 32–100 million. ↩

“The air in my house was making me sick. No one could tell me why. And no one could tell me it was a healthy environment again.”
