Not familiar with them, I use the cheap old residential foam AC filters you buy at Lowes, Home Depot, Walmart and the like, in our front unit. Usually wash them a a few times before replacement. A year of fulltime heatpump/AC use is about the norm for us. I have a "washable" filter in the rear unit, been there 4 or 5 years and washed monthly. Both seem to work equally well.
