Indoor Air Quality Monitoring in Washington
Seattle and the rest of Washington have earned a reputation for rainy weather, but that’s not all that residents have to deal with. Wet winters and dry summers can both impact indoor air quality throughout the state, and smoke from wildfires can find its way into any home or business and make breathing difficult. Wouldn’t it be nice if your property’s ventilation components could detect signs of poor indoor air quality and improve it on their own? With an Overture® system installed, they can. Overture IAQ handles everything from air data to air control so you don’t have to.
Measures the Room, Runs the Equipment
A monitor shows you a number. Overture measures the room and runs the equipment. Once the system is installed, it connects with compatible systems by way of 24V dry contacts, 120V outlets, and the Wall Control. Its programming allows it to run equipment without any third-party integrations. And with Room Sensor, Smart Plug, and Wall Control components already integrated, Overture is a true turnkey solution anyone can use to get healthy air, automatically.
In 2025 Overture supported a field study by TRC, paid for by California's CalNEXT program (report ET24SWE0015, final report December 19th, 2025). The report describes a “field demonstration at 17 dwelling units in two multi-family housing sites to evaluate IAQ performance, energy impacts, and user satisfaction.” Its finding: “The results show that smart ventilation systems can maintain acceptable IAQ while reducing ventilation runtime compared to continuously operating systems provided the underlying ventilation infrastructure is properly designed and functioning.”
How Overture Measures Indoor Air Quality
When Overture is active, it’s constantly monitoring five key indoor air quality levels:
- CO2, which is one of the key indicators of ventilation performance
- PM2.5, tiny particulate matter that can stay suspended in air for long periods
- TVOC, or total volatile organic compounds that fluctuate throughout the day
- Relative humidity, from which Overture calculates the dew point, the number that tells you whether moisture will condense on a cool surface
- Temperature, which provides context for all of Overture’s indoor air quality measurements
Once installed, the Overture system can run compatible equipment located in any room for targeted indoor air quality improvement. For example, if wildfire smoke enters a home and affects the air quality, Overture sends a call to the furnace blower so the house air passes through the filter.
Ventilation systems that are compatible with Overture systems include:
- Bathroom exhaust fans
- ERV boost modes
- Range hoods
- Dehumidifiers
- Make-up air systems
- Forced-air blowers
Residential & Commercial Indoor Air Quality Monitoring
Overture IAQ has developed scalable IAQ solutions for residential and commercial purposes. Overture works for one building and is sized for 500 sites and up, so tracking indoor air quality across a portfolio in Washington is as simple as measuring one single-family home in Vancouver. Here’s how it works:
Residential Indoor Air Quality Monitoring
Homeowners will use the Overture app to receive real-time indoor air quality measurements and keep track of the system’s actions. Through the app, a user can access reports, alerts, and system activity for the bedrooms, the basement and the bathrooms they care about.
Overture IAQ’s IAQ monitoring system works for:
New-Construction Homes
Home builders and contractors are always trying to stay on top of the latest energy efficiency solutions. Overture is a natural fit for a brand-new home with mechanical ventilation systems, especially in an area such as Washington with a highly eco-conscious population.
Older Home Retrofits
Updating an older home to meet modern standards for comfort and energy efficiency is easier with Overture. This is because Overture IAQ’s systems are far easier to install than an entirely new HVAC system would be. Just plug it in, set it up, and enjoy healthier air.
Commercial Indoor Air Quality Monitoring
Keeping track of indoor air quality levels across dozens, if not hundreds of sites can seem like a daunting task. Overture makes it simple no matter where you’re monitoring from. Overture IAQ’s commercial systems are highly scalable, and use a web-based interface that includes a user-friendly Google Maps dashboard view.
Overture systems are used in many different types of commercial properties throughout Washington, such as:
- Office buildings
- Schools
- Manufacturing facilities
- Dormitories
- Assisted living communities
- Strip malls
- Military housing
- Small offices
- Healthcare centers
- Multi-unit residential properties
Overture IAQ’s Vape Alert Technology
Indoor vaping is a common problem at schools, dormitories, offices, and other commercial properties. It may smell more pleasant than cigarettes, but the vaping particles aren’t much better for people. Overture identifies a vaping event by its signature: particles rise while carbon dioxide stays flat. People raise both; an aerosol raises particles alone. When Overture sees it, it notifies building managers immediately so they can take action.
Take the Next Step Toward Better Indoor Air Quality
Overture systems measure CO2, PM2.5, TVOC, relative humidity, and temperature, and then run the ventilation equipment as needed to maintain healthy IAQ levels. Best of all, it’s a turnkey, plug-and-play solution that’s scalable, customizable, and capable of doing it all right out of the box. Plus, it comes with a one-year warranty on parts and hardware.
