The main goal of this research project is to determine the effectiveness of commercially available air filters and to compare different kinds of commercially available air filters in certain categories. With recent record-breaking wildfires and the Covid-19 pandemic, research on the effects and features of nanoparticles has become increasingly important. Inhalation of nanoparticles in smoke can result in severe health effects on humans, affecting especially the respiratory system. As nanoparticles can pass through cell membranes, absorption occurs rapidly and affects many different parts and functions of the human body. While air filters are an effective method of reducing small-sized particles in flowing air, current filtration standards only apply to larger scaled microparticles, and filtration efficiencies for nanoparticles are often unknown.
This thesis analyzes the filtration efficiency of commercially available air filters for nanoparticles generated by woodsmoke. Four different air filters were tested for two different kinds of smoke. While trends were observed, high standard deviations caused inconsistent results.
