Understanding Indoor Air Pollutants: Types, Sizes, and Impacts on Health

This guide explores the various indoor air pollutants, their typical sizes measured in microns, and their prevalence in indoor environments. It highlights how particles like dust, pollen, bacteria, and viruses can be suspended in the air, affecting our health. With insights into how these pollutants linger in the breathing zone and the duration of their suspension, the importance of air filtration systems, such as HEPA filters, is emphasized for effective odor and contaminant removal. Learn more about maintaining healthier indoor air quality!
