Room for improvement
The AprilAire 8100 is an elegantly simple ERV that performs well and has few parts to fail or replace. Cost is reasonable and installation easy. The two main drawbacks are the lack of a condensation trap and inadequate filtration system. The condensation trap is not a problem in areas that don't have climate extremes. The EZ Clean filters are fine if the intake is dust free. But because they are positioned after the intake motor, it can accumulate debris and clog the transfer core. I use a pleated filter in the intake duct ahead of the intake blower.
