Wildfires, escalating in intensity each year, have plunged California into a crisis of indoor air quality, particularly during the wildfire season. This thesis dives into a potential solution: the use of exterior green walls as a respiratory system, employing phytoremediation. Phytoremediation harnesses the plant's natural ability to cleanse soil, water, and air of contaminants. The prevalence of heavy smoke, composed with particulate matter 2.5, from these increasingly fierce fires poses a significant health risk in California. This research advocates for a plant-based biological filtration system as a promising alternative to conventional methods.
