Why do the pads in my EnviroSept sometimes turn black?
This is a common question that we receive, especially in the wintertime. During most of the year, the collector pads will change color throughout from a snowy white to a dirty gray. However, in the wintertime, customers with oil or gas furnaces will see the collector pads turn to a dark gray or black from the hydrocarbons in the air as a result of the combustion of fuels. Customers that burn candles or have wood stoves and fireplaces will experience the same results. This serves as a testimonial to the highly efficient performance of the EnviroSept, as it removes the smallest sub-micron particles that other devices can’t begin to remove.
