Aira Sense Home Wellness Monitoring — Questions & Answers

Aira Sense is the indoor measurement layer of Pico X Health's three-part home wellness system. The unit continuously measures humidity, temperature, CO2, TVOC and particulate matter in your room, and pairs those live readings with two AI-calibrated indices: AMRI, the Aira Mould Risk Index for outdoor conditions across Singapore, and the Aira Home Wellness Index, the household assessment at airahales.com/home-wellness. Together they warn you before conditions turn mould-friendly, tell our team when a service such as aircon cleaning or dehumidification is actually needed, and verify the outcome afterwards. From S$3.50 a month, free with Pico X Health services.

AMRI — the Aira Mould Risk Index — is the outdoor layer. It turns Singapore environmental data (humidity, rainfall, temperature and wind) into a daily 0–100 mould risk score with a clear action, such as whether today is a good hour to open the windows or keep them shut. The Aira Home Wellness Index is the household layer: the free assessment at airahales.com/home-wellness that profiles your specific unit — its age, orientation, ventilation, past leaks, structural weak spots, noise and UV exposure — and ranks your prevention priorities. AMRI tells you what the environment is doing to homes like yours today; the Aira Home Wellness Index tells you how vulnerable your home is to it; Aira Sense measures what is actually happening inside your room.

Both AMRI and the Aira Home Wellness Index are AI-calibrated against 3,000 Pico X Health customer data points and Singapore environmental sensor data, using our own algorithm rather than a generic humidity rule of thumb. The calibration is refined against real remediation outcomes — which homes recurred, which held, and what the readings looked like in each case — so the scores reflect what actually predicts mould in Singapore building stock.

Because most Singapore homes breathe. Indoor humidity is largely a function of what is happening outside and how you ventilate against it: opening windows during a wet monsoon hour actively imports moisture, while the same action on a dry, breezy afternoon dries the home out. Reading indoor conditions alone tells you that a room is humid; reading them against AMRI tells you whether the cause is outside pressure, your ventilation behaviour, or a defect such as a leak or cold bridge — and therefore what to do about it.

AMRI and the Aira Home Wellness Index are free and predictive — they tell you the risk. Aira Sense is the confirmation: it measures your actual room, so guidance becomes specific to your bedroom, nursery or clinic instead of general to Singapore, and it is the only one of the three that can prove a remediation worked. If you have never had a mould problem, the two free layers may be enough; if you have had one, or are paying for works, the measurement layer is what closes the loop.

Mould needs sustained surface moisture, not a single humid afternoon. Aira Sense watches relative humidity over time and flags the hours your rooms spend above the growth threshold — typically 70% RH — long before a stain appears. Read against the day's AMRI score you get a specific action for the conditions of that day, such as running aircon dry mode, opening windows during a dry afternoon, or keeping them shut during a monsoon hour when outdoor air is wetter than indoor.

We take a sensor baseline before works begin and keep the sensor in place afterwards. The reading trend after remediation is the proof: humidity hours in the danger zone should fall and stay down. If they do not, the moisture source was not fully resolved and we come back under warranty. Most remediation companies leave the job with no measurement at all, so nobody can tell whether the home actually improved.

Relative humidity and temperature (mould risk and condensation risk), CO2 (ventilation adequacy and stuffiness), TVOC (chemical off-gassing from furniture, paint or cleaning products) and PM2.5/PM10 particulates (haze, cooking and aircon filter condition). Together these describe both the mould risk and the general air quality of the room.

A hygrometer shows a number. A consumer air monitor shows a graph. Aira Sense is connected to a remediation team — the readings trigger a specific recommended action, and when the action needs a professional, the service is booked and later verified against the same sensor data. It is the measurement layer of a service, not a standalone gadget.

The Aira Home Wellness Index is the free household assessment at airahales.com/home-wellness. It profiles your specific unit — Singapore building stock, weather zone, orientation, ventilation, past leaks, neighbour-unit patterns, noise levels and UV exposure — and returns a unit-level risk score, the structural weak spots most likely to grow mould, and what to fix first versus what can wait. It is AI-calibrated on 3,000 customer data points with our own algorithm. Aira Sense then measures the same home live, so the assessment stops being a prediction and becomes a running record of how your home is actually doing.

Aircon fouling shows up in the data before it shows up in your nose. When cooling cycles start coinciding with rising particulates, humidity that no longer drops during cooling, or a TVOC rise, that pattern means the coil and drip pan need attention. We service on that signal instead of on a fixed calendar, so you are neither cleaning a clean unit nor waiting until it smells.

From S$3.50 per month. It is included free for the duration of Pico X Health service engagements such as mould remediation, anti-condensation coating or aircon servicing, so existing customers get the monitoring layer at no extra cost.

In the room that matters most to you and, if you only have one unit, the room with a history of problems — usually a bedroom, nursery or the room adjacent to a bathroom or aircon ledge. Place it at roughly chest height, away from direct aircon airflow, windows and heat sources, so it reads room conditions rather than a draft.

Yes, a normal 2.4GHz home wifi network. The sensor uploads readings continuously so alerts, trends and your AMRI-adjusted guidance stay current even when you are away from home.

Readings are environmental only — humidity, temperature, CO2, TVOC and particulates. There is no camera, no microphone, and no recording of anything said or done in the home. Data is used to generate your alerts, to sharpen your Aira Home Wellness Index and AMRI guidance, and, where you engage us, the before-and-after verification for your service.

No. A sensor tells you the conditions of the air; an inspection tells you where the water is coming from. Aira Sense catches the risk early and confirms outcomes afterwards, but a thermal and moisture inspection is still what locates a leak, a cold bridge or a failing waterproof membrane.

Aira Hales is the conversational layer — the free Telegram companion that answers questions, reads photos and pushes weather-based mould guidance. Aira Sense is the measurement layer that gives Aira Hales your actual room data, so guidance becomes specific to your home instead of general to Singapore.

Yes. Multi-unit deployments are used in offices, clinics, childcare centres and F&B premises where indoor air quality is both a compliance and a reputation issue. The same loop applies: baseline, alerting, service triggered on data, and a documented improvement trend you can show to a landlord, an auditor or a tenant.

It will tell you whether the conditions in the nursery are within the range associated with healthy sleep and low mould risk — humidity, CO2 build-up overnight, and particulate levels. It is not a medical device and does not diagnose health conditions, but it removes the guesswork from questions like whether the room is too humid or too stuffy.
