Product review (5 stars): Ridiculously Awesome Price!
Considering I generally pay ridiculously more than this ($50 for 1 versus $48 for 3) I was very skeptical on the quality.  After scouring some of the extremely thorough reviews, I decided to give them a chance.

Installation is exactly the same as it was with the name brand (and more expensive) model we used previously.

A filter installed in May made it through the end of the summer (when we use the filter the most) and ended up lasting a total of about 6 months.  The name brand, expensive version lasted us (during this same time) a max of 4-5 months.

Final verdict is THESE filters are better than the name brand, more expensive version and I will continue to buy them here as long as they offer them.
