Apart from regular cleaning, there are a number of measures that, if followed consistently, can bring proven benefits to indoor air quality.
The first suggestion comes directly from the founder of Biosafe, Arch. Leopoldo Busa (who you can listen to in the webinar "Misurare la qualità dell'aria indoor" ("Measuring indoor air quality") produced by Sistem Air, editor's note), who states that it is essential to keep the room thermostat at a temperature that never exceeds 20°. This is because an increase in temperature corresponds to an increase in the volatility of harmful chemical compounds found in an inhabited environment.
For the architect, it is always advisable to wear an extra sock or a heavier jumper than to raise the temperature of the home heating.
Another suggestion is to open the windows for a few moments during the day, perhaps in the cooler hours, or when you have just finished cooking or taking a shower to keep humidity under control.
Finally, not smoking in the home and changing the filters of air conditioners at the beginning of each season, washing them with soap and water, are two suggestions that, together with the others, can guarantee you a healthy and safe home environment.
