While outdoor air quality has remarkably improved in our towns and cities in the last 30 years, the quality of indoor air is still an unsolved issue. Due to the presence of many chemical substances (cleaning products, air fresheners, solvents, paint, etc.), poor ventilation and the accumulation of outdoor pollutants, indoor air is highly polluted and this affects people’s health and increases the number of allergies, which have become quite common. ENVIRA develops devices for measuring the quality of indoor air in order to improve the environment where we live and work. These devices also help improve our buildings sustainability, optimizing the ventilation and cooling systems.
