We just built a house and I need to replace the filter of our Geothermal unit. I have e-mailed the manufacturer to find out what we should use, however, they just said to use the same type of filter that the unit came with. I have looked everywhere online and cannot find a 16 x 30 x 1 fiberglass filter except for a company that makes a PDA type (here is what they say: Disposable panel filters are rigidly constructed using a progressively dense PolyStrand� media to maximize dust holding capacity. Two metal grids are thermally bonded to the internal sides of a heavy-duty, one-piece craftboard frame to maintain the media's integrity under adverse operating conditions)

Does anyone know if that will work or if I should get pleated filters instead? Thank you!
