The application of concentrated plant extracts to a porous material designed to purify the atmosphere involves introducing volatile organic compounds into an environment alongside a system intended to remove such substances. This process attempts to imbue filtered air with the therapeutic properties attributed to these botanical derivatives.
This practice gains traction due to perceived advantages such as enhanced well-being, odor masking, and potential antimicrobial effects. Historically, aromatherapy has long utilized plant-derived scents for their purported health benefits, leading to exploration of different delivery methods. The use of air filters as a medium for dispensing these oils represents a modern adaptation of traditional practices.
