The "Clean Air" program is a government initiative aimed at improving air quality in Poland. The program is targeted at individual residents who want to improve the insulation of their homes and replace outdated, non-ecological heating sources with more energy-efficient and environmentally friendly ones. Through the program, funding is available for the replacement of windows, boilers, installation of heat pumps, building thermomodernization, and installation of photovoltaic panels. The funding ranges from 40 to 100% of the investment value, depending on the income per person in the family and the location of the building.
