[hitchup]

We did the white knobs as posted sometime back on the forum. Only negative was they were glass & one fell on the countertop & chipped the knob. It's so much easier for me to clean filters.

I also found more of the same foam material at WalMart & is cheaper than CW or Lowe's. Its a seasonal item since it was sitting with the AC's. Tried the electrostatic filter material but it's just as easy to clean & rotate with new foam pieces I cut.
