Lution identifies what you're breathing. Think of it as a nutrition label for the 40 pounds of air you breathe every day.¹ Lution shows the ingredient list — over 100,000 particle types, from mold and bacteria to dander and fibers, plus the gases in the air — and weighs each one by what it is, how much there is, and for how long. Not all particles are equal. Not all gases are the same. Lution ranks what matters most, gives you a Lution Level every morning, and tells you what moves it: filtration, ventilation, moisture control, and reducing a source where you can.

One convenient system, delivered to your door.

Read your air continuously, catching the patterns and shifts a single test can't see — a test is a photograph of a moving thing. They read particles (matched to what your lab results found), formaldehyde, VOCs, NOx, CO₂, temperature, humidity and pressure. The number of sensors is sized to your home's layout.

Air drawn through a home's window and filtration over time

Over a million times more air than a spot test.

A typical spore trap test samples 25 to 50 liters of air in ten minutes — a lunchbox of air, from one spot, on one afternoon. Your home's HVAC filter moves more than a billion liters in three months; a good HEPA purifier moves about a billion in six.¹ Either way, Lution's sample is over a million times — sometimes a hundred million times — larger than a spot test. A small sample catches whatever happened to be passing by. A big one catches what's rare, what's constant, and what only shows up at 3 a.m. — so what we report is your air, not a moment of it.

Identified by name.

Accredited partner laboratories identify mold and bacteria by gene-targeted sequencing, and the materials in your dust by microscopy read by laboratory scientists — because what a particle is matters as much as how much of it there is.

Weighed by what it is.

Each ingredient is weighed by what it is, not just how much there is, so what matters most rises to the top.

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. ↩
