The US EPA estimates that even buildings fitted with very sophisticated HVAC systems can concentrate pollution levels up to 100 times higher than outdoors. Furbish Company installs Naturaire Systems as a means using of natural biological processes to break down and remove indoor air pollutants. Airflow speed through each Naturaire biofilter is engineered to treat indoor at an appropriate rate for the pollutant-loading specific to the building in which it is installed. Using the air exchange rates for the biofilters we have installed we are able to calculate in real-time the cumulative air volume filtered by the biofilters since founding our company in 2003.
