Overture Indoor Air Quality Monitoring for Assisted Living Centers

In assisted living, air quality is a resident-safety issue. Older residents, and anyone with a respiratory or cardiac condition or a compromised immune system, are the most sensitive people in the building to fine particles, high CO2, and damp air that grows mold. Overture puts a Room Sensor in each space, tracks the air in real time, and automates an action when a level moves out of range. Your team sees current conditions across the whole facility on one screen and gets the documented record that supports your compliance and accreditation reviews.

The two air problems that matter most in assisted living

Two pillars drive resident health and building safety. Overture tracks both and acts on both.

PM2.5 - the health load

PM2.5 is particulate matter 2.5 micrometers or smaller, roughly 30 times thinner than a human hair. Particles that small slip past the body's defenses, reach deep into the lungs, and cross into the bloodstream, which is why PM2.5 worsens asthma, bronchitis, COPD, and cardiovascular disease. Research from Max Sherman (2024) attributes about 80% of the chronic health harm from indoor air to fine particles. The EPA limits are 35 µg/m³ over 24 hours and 12 µg/m³ as an annual average, and for a frail population the target is to stay well under those numbers.

Sources inside a facility include: - Cooking on gas stovetops and other appliances - Burning candles - Resuspended dust from cleaning and foot traffic - Outdoor smoke and traffic pulled in through the building envelope (wildfire smoke is a growing one)

Dew point and humidity - mold, infection, and durability

Moisture is the pillar most assisted-living pages ignore, and it is the one that causes mold and supports infection. The physically primary variable is dew point, not relative humidity: when a surface in the building sits below the dew point of the air around it, water vapor condenses on it and mold follows. ASHRAE points to a 60°F indoor dew-point ceiling. Overture tracks dew point and humidity in each space and, when it climbs, automates a response (boost an ERV, run a make-up air fan, or signal a dehumidifier) before condensation starts. Drier air also slows the survival and spread of many airborne pathogens, which matters in a building full of vulnerable residents.

How Overture works - monitor, then automate the action

The Overture Room Sensor is a small, unobtrusive device that plugs into a standard outlet. No HVAC retrofit, no rewiring. Each Room Sensor tracks CO2, PM2.5, TVOC, humidity, and temperature in real time and reports it to one dashboard, so you get room-by-room visibility across the whole facility.

What sets Overture apart is that it does not stop at a reading. When a level moves out of range, the system automates an action through a Smart Plug or a Wall Control: - Turn on a bath fan or range hood to clear a spike - Put an ERV into boost mode to bring in fresh air - Run a dehumidifier when dew point climbs - Start a make-up air fan or the forced-air blower to circulate and filter air.

No other IAQ sensor takes the action for you. Overture can also point you to the right filtration and dehumidification equipment when a space needs it. To be clear, the Room Sensor does not clean the air itself - it measures the air and triggers the equipment that does.

Built for a building, not a single room

For a handful of locations, the Overture app runs the whole system from your phone. For a multi building operation with 50 to 500 spaces, the web-based interface gives your facilities team one view of every room, every alert, and every automated action. The two work together as your footprint grows.
