Product review (5 stars): Appears to be of Excellent Quality
These filters arrived well packaged and look fine.  I will not be needing these for a few months as I just replaced my filter recently.  But I buy in advance to have on hand when needed.  So hopefully these will install and work fine when the time comes.  If not I will adjust my rating.  The only thing that I did notice is that the instructions refer to an arrow on the back of the filter to line up with when installing and I do not believe that arrow is there.  But shouldn't be a big deal (I hope) as I have installed numerous filters by now.  Based on what I can see so far, I can recommend these filters.
