Product review (3 stars): Generic AC-819 Wick Filter
I have used generic wick filters over the years and up to this point all have had a heavy foil matrix in the center of the filter for added strength.  These do not have that feature.  The filters appear to be the correct height but are a little too long to fit easily in the holder.  I trimmed the edge on the first one and now it is a tad loose so I will try cramming the entire filter into the holder when I replace the first one.  The first one has only been in service for a couple of weeks but seems to be holding up so far.  On the plus side, these filters were less expensive than the ones that I have used in the past so at this point, I would call it a push.
