Product review (5 stars): 1) Great price, and 2) They seem to work as ...
I ordered this because it was a match as a replacement for my expired filter, and I didn't read much more of the description. Based on the price - and I've been buying different versions of these things for a while now - I thought I was buying 1 filter. Man, was I pleasantly surprised when a package of 3 filters arrived. So, 1)  Great price, and 2)  They seem to work as advertised.
