For decades, the residential building industry has leaned heavily on ASHRAE 62.2 as the reference point for indoor air quality. This has helped move homes in the right direction by requiring mechanical ventilation in tighter, more energy-efficient buildings. However, the industry has often treated compliance with ASHRAE 62.2 as if it were equivalent to delivering healthy indoor air.
The Harm Paradigm reframes indoor air quality as the cumulative effect of many small, location-specific pollution sources rather than a single metric, asking where harm to occupants is actually occurring. Breathe implements this by using distributed sensors to detect room-by-room pollutant sources and exposures in real time and respond with targeted ventilation, filtration, and humidity control to reduce health impacts rather than just meeting averages.
When managing indoor air quality (IAQ), it's easy to focus exclusively on what happens inside your home. However, outdoor air quality plays a critical role, especially when it comes to fine particulate matter, or PM2.5. These microscopic particles, produced by sources like vehicle emissions, industrial activity, and wildfires, can enter your home through ventilation, open windows, and even tiny cracks in the building envelope.
