evidence: Oxygen-Producing Capacity of Snake Plants [...] While the exact amount of oxygen produced by a snake plant varies depending on factors such as size, light exposure, and environmental conditions, research suggests that an average-sized snake plant can produce around 5-7 grams of oxygen per day. This is a modest amount compared to the oxygen requirements of humans, but it can still contribute to improving air quality in indoor spaces. [...] While snake plants may not produce enough oxygen to fulfill our daily needs entirely, they can still contribute to increasing oxygen levels in enclosed spaces. This can be especially useful in rooms with limited ventilation or during nighttime when windows are closed.
