Thanks to the still rampant COVID-19 / SARS-CoV-2 pandemic out there, Easter is just one of the many things in early 2020 that has been moved into the safety of your home, just like Marathon running, children’s education and office work. With the time spent at home massively increased, new things start to matter: for example indoor air quality. So, I decided to dedicate one Life-Sparring Round to indoor air quality and the setup we run in our crib, using the Kaiterra Laser Egg+ air quality sensors.
