Air pollution is one of the most important current environmental health problems, threatening health in a significant way and contributing to the development of many diseases. The reason for exceeding the air quality standards is mainly low emissions, including, inter alia, pollution from individual sources, such as households. Improving air quality requires a comprehensive and wellthought- out approach when introducing a number of legal regulations. Current and planned regulations aimed at limiting air pollution do not take into account important social issues, such as the right of the poorest to heat or the growing percentage of people falling into energy poverty, which are essentially influenced by three factors: high energy cost, low energy efficiency of buildings, and low household income, which translates into the quality of fuels burned, often including garbage. It should be noted, however, that adopted resolutions may constitute a barrier to the development of innovation in the heating industry. As a result of the regulations already adopted, only installations complying with class 5 standards will be allowed to be used, which means that lower-class boilers will have to be replaced with new, top-class boilers, but no other technical solutions are taken into account – e.g., filters, which in combination with non-class or class 3 and 4 boilers may result in a reduction of emission.
