WHY YOUR INDOOR AIR MATTERS
A beautiful home doesn’t guarantee clean air.
90%
of our time is spent indoors.
US EPA ↗1 in 5
of us will get a lung condition in our lifetime.
Asthma + Lung UK ↗A little less wondering. A clearer understanding.
Smoke, sprays, damp and mould at home can affect lung conditions such as asthma. Syra shows you when the air in your room changes, so you’re not left guessing.

Know when the air
at home changes.
A gentle notification on your phone when Syra notices a change, even when you’re out, and a quiet all-clear when it settles.
For families keeping an eye on asthma or allergies, it means knowing when the air changes, rather than guessing. Open the app to see what changed and what usually helps.

What can SYRA measure?
Particles, gases and the conditions in your room.
All brought together in your app.
Airborne particles
Tiny particles suspended in the air, including smoke and dust. Fine particles can reach deep into the lungs, worsen asthma and affect heart health.
Source: EPA ↗Carbon dioxide
A gas we breathe out. Rising indoor levels can signal poor ventilation; very high concentrations can cause headaches and dizziness.
Source: HSE ↗VOC Index
Volatile organic compounds are gases released by products such as sprays, cleaners and paints. Some can cause headaches and eye or throat irritation, depending on exposure.
Source: EPA ↗NOx Index
Nitrogen oxides are gases produced by fuel burning, including gas cooking. Nitrogen dioxide can inflame airways and worsen asthma.
Source: EPA ↗Temperature
How warm your room is. Temperature shapes comfort and sleep, and gives the rest of your readings their context.
Humidity
How much moisture the air holds. Excess humidity encourages mould, which can trigger allergies and asthma.
Source: EPA ↗About these measurements & health information
Health effects depend on the pollutant, concentration and length of exposure. VOC and NOx indices show relative changes, rather than individual chemical concentrations or health-risk scores. For everyday CO₂ readings, the main use is understanding ventilation; direct harmful effects occur at much higher concentrations.

How does Test Mode work?
Choose an activity, follow the guided session, then review your readings before, during and after. Save the session to revisit it later.
What’s included?
Your Syra, companion app and core Test Mode, bringing everyday room readings and guided testing together.
How can I compare my routines?
Give your sessions recognisable names, save them and review them together. Repeating a routine under similar room conditions helps you make more useful comparisons.
What can I explore?
Candles, spray deodorants, cleaning sprays, other aerosols, cooking and fragrance. Test Mode follows the room’s readings throughout the activity you choose.
