Answers to your questions

Airsafe is a small, discreet air quality meter. You plug it into any USB-C port, and it quietly monitors the air around you, staying out of your way. If the air needs attention, due to high CO2, temperature, or unusual humidity, it gently glows to get your attention, or sends you a notification - all configurable. Aranet is a stand-alone monitor powered by batteries, designed more for industrial use cases than use at home and work.
Quality of the air you breathe directly affects your cognition, creativity, mood and energy. High CO2 and high temperature, which are common indoors, especially in hot climates, decrease your cognitive performance, make you sleepy, irritated and tired. Humidity affects you as well - too high and you will sweat like in a sauna, too low and you are at risk of nasal infections, skin irritation and airborne diseases. The optimal air is 18-22C, 40-60% humidity and as low on CO2 as possible, ideally <800ppm. AirSafe helps you maintain the best air possible, so that you can do your best work and live your best life.
