What is the initial step in the three-part air quality improvement strategy recommended by the EPA?
Answer
Control the source of contamination
The hierarchy for improving indoor air quality begins with controlling the source of the contamination, as removing the problem at its origin is the most effective approach. The second step is to improve home ventilation to bring in fresh air and dilute pollutants. Using an air purifier is the third and final step in this strategy. Relying solely on filtration without addressing the source or ventilation limits the ability of the device to improve overall air quality, especially regarding issues like moisture-related mold growth.
