Introducing the GLAS® smart thermostat by Johnson Controls.
Monitors air quality.
GLAS provides you with the information you need to help make your home healthier. The smart thermostat monitors humidity, tVOC and eCO2 levels indoors. It even reports pollen and air quality outdoors - especially helpful for asthma or allergy sufferers.
What's behind GLAS?
Johnson Controls invented the room thermostat 135 years ago. With your family's health and energy savings in mind, we reinvented it with GLAS. The smart thermostat can help create an efficient and healthy space, and its clean translucent interface reimagines any space.
