If you've been on our website, you've seen this counter on the commercial homepage. But did you know what it means and how it is calculated?

 

While Dynamic Air Cleaners can reduce maintenance costs nicely, by far the biggest savings are in the form of energy. Studies show that in general, 90% of the cost of filtration is energy and not the cost of the filter. That is, the primary cost of filtration is the energy required to push air through the filter. With low static pressure and the flattest loading curve in the industry, Dynamic Air Cleaners save significant fan energy and brake horsepower. For example, a MERV 14 passive filter with a MERV 8 pre-filter consumes 3 times more energy than a Dynamic V8. Further, Dynamic Air Cleaners can help implement the IAQ Procedure of ASHRAE 62 to result in more cleaned air and less outdoor air. This saves the energy it takes to heat, cool, dehumidify and clean the outdoor air.

 

So what does counter measure? Started in 2009, it measures the cumulative savings from reduced fan energy and reduced outdoor air compared to base case operation. In virtually all commercial jobs, we have computed the savings and payback as part of the applications engineering. Operation with Dynamic Air Cleaners is compared to passive filtration and/or the use of the Ventilation Rate Procedure. This information is the basis for the savings numbers in the counter. While the energy cost for each job may vary anywhere from $0.06 to $0.28/kWh, we assume a conservative $0.11/kWh in the calculator.

 

The savings are expressed in U.S. dollars, KWH, and metric tons of carbon dioxide. Each month we update the savings with new installations.

 

We are extremely proud that our Air Cleaners have saved our customers over $31 Million in energy-and counting!
