A smarter way to know what you breathe.

Indoor air takes more than an AQI. It takes What's actually in your air — the particles, vapors, and microbes present, identified by name rather than lumped into one number. and Where each finding comes from and how much of it you've been breathing, for how long — the source and the dose. — 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

Track

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

Capture

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.

The Lution lab analysis

03 — The Lab

Analyze

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

Guide

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. ↩

Air monitors count. Lution explains.

A used HVAC air filter

Time to change your filter.

Your HVAC filter is no longer working efficiently and is due for a change.

An industrial smokestack against the sky

Close & seal your windows.

Outdoor particle levels are rising with the wind from the east. Close the windows and run filtration until it passes.

Fine airborne moisture wisps

Moisture levels are high.

Damp air favors mold growth. Try running the AC or a dehumidifier.

A vacuum cleaner

Check your vacuum filter.

Check that your vacuum uses a HEPA filter, so it doesn't return fine particles to the air.

A glass of water

Time to deep clean the dishwasher.

Your latest lab results found bacteria that favor standing water. Dishwasher and washing-machine seals are common sources — a deep clean helps.

A rising column of smoke

Open your windows.

Combustion particles are high — candles or a fireplace are the usual sources. Open a window for a while, the air outside is better.

A frying pan on the stove

Turn on your vent hood.

Particles are rising the way they do when someone's cooking. Try the vent hood or a fan.
