Determining the Effectiveness of a Mycelium-Based Air Filter on the Removal of PM2.5 from a Controller Environment

CSEF · 2026 Environmental Engineering (Senior Division)

Ariana Joel

Overview

This study investigates whether a biodegradable mycelium-based air filter can serve as a sustainable alternative to conventional HEPA filtration in reducing fine particulate matter. Both filters produced substantial decreases of PM2.5 concentration, with the HEPA filter achieving an average reduction of approximately 99.9% and the mycelium filter achieving roughly 95.54%, while the control condition experienced a 0% reduction, indicating no natural settling of the particles. Statistical analysis showed that the HEPA filter modeled exponential regression, while the mycelium filter modeled logarithmic regression, indicating the HEPA filter is more efficient in removing PM2.5 particles. However, the mycelium filter showed significant reduction, living it has the potential to serve as a filtration material.
