Energy Consumed by Filters- Easy and Expensive to Miss

The most obvious consequence is a HVAC system breakdown, usually a fan failure from the increased load. This is very expensive but also hard to not attribute to the deferred maintenance. Much harder to catch but much more common is the increased energy consumed from a filter that is in use beyond its ideal changeout […]

Higher Filter Efficiencies – What do they Cost?

One thing that is commonly accepted about filter efficiencies – increased removal efficiency generally means increased pressure drop across a filter, or an increase in energy consumed. For example, look at the TCO of our Synthetic Rigid Filters at MERV 11, 13 and 15 when prefiltered by the Series 400 Standard Capacity Pleat. To combat […]

Indoor Air Quality 101

Conventional wisdom tells us to employ MERV 13+ filters to remove particulates from  the air for both fresh outside air and recirculated air. Anything below MERV 13 is basically just protecting your equipment, whereas MERV 13 and above filters smaller particulates in the 0.3-2.5 micron range that can get in your lungs and potentially your […]

Filtration Total Cost of Ownership – What you need to know.

When evaluating multiple filters against each other, it is very common to focus on the initial DP as the primary indicator of Total Cost of Ownership (TCO) of a given product. However, that is only one part of the story. As it turns out, the Dust Holding Capacity (DHC), or more generically, the amount of […]
