This page displays a ranking of plants based on VOC Efficiency, which measures how effectively a plant removes volatile organic compounds relative to its leaf surface area (μg/cm²). This metric allows us to identify high-performance purifiers even if they are smaller in size.
To calculate VOC efficiency, I used a SQL query that divides the total VOCs removed by the plant’s leaf area, rounding the result to two decimal places. The list was filtered to exclude plants with zero surface area to ensure data validity.
Gerbera daisy once again leads the list, not only removing the most total VOCs but also doing so with the highest efficiency—proving both powerful and space-saving. This ranking helps prioritize plants when space is limited but purification performance is essential.
