Objectives: This study was conducted to determine the impact of aquariums on indoor air quality for improvinghumidity and reducing indoor air pollutants. Methods: An air-conditioning chamber was used to determine humidity increase by aquarium volume at threedifferent temperatures (20 C, 25 C, 30 C). Humidity increase was measured for 21 hours (20 C) and 12 hoursoooo(25 C, 30 C) while placing five different volume of aquarium in the chamber. Concentrations of several volatileoo organic compounds and formaldehyde were measured after a known amount was injected into the chamber withand without an aquarium. Results: The humidity inside the chamber increased when the aquarium was inside the chamber. Humiditychange was similar at 20 C, 25 C, and 30 C, but slightly higher at higher temperatures. The bigger the aquariumooovolume, the higher was the humidity increase that occurred. Humidity increase by the aquarium was sufficientto increase indoor humidity in winter and negligible in summer. Concentrations of some water-soluble indoorair pollutants and formaldehyde were decreased with the aquarium inside the chamber. Conclusions: An aquarium could increase indoor humidity in winter, while the humidity increase is negligiblein summer. An aquarium could decrease some water-soluble indoor air pollutants, including formaldehyde. Thisresult implies that an aquarium may have positive effects on indoor environmental quality.
