Notes on the air we share.
We explore what shapes the air inside buildings and turn research, standards and real-world data into practical ideas people can use.
Can Cleaner Classroom Air Improve Test Scores?
In 2015, a huge gas leak near Los Angeles led to air filters being installed in every nearby school. Nobody planned it as an experiment, but it became one of the clearest studies we have on what cleaner classroom air does for learning. Pupils in schools with filters scored higher in maths and English. The researcher says the gains were about as large as cutting class sizes or giving pupils intensive tutoring. What happened?

It is not a certificate you receive once. It is a result y

How Many IAQ Monitors Does a WELL Project Need?
Two questions come up on almost every WELL project: how many indoor air quality monitors do we need, and where should they go? How many monitors does WELL require? The WELL Performance Verification Guidebook sets monitor density by occupiable area, not gross floor area: Occupiable spaceMonitor densityMinimumUnder 3,250 m²1 per 325 m²23,250 to 25,000 m²1 per 500 m²10Over 25,000 m²1 per 1,000 m²50 Round up, and apply the density across the whole project, not floor by floor.
