Product review (1 stars): Not Worth the Money
Worth the extra money it costs over the cheap off-brand one I picked up in an emergency at the local hardware superstore. I can totally tell the difference.

1/24/17 - UPDATE: The quality of these filters has gone way down. The last two I bought started falling apart within a couple of weeks, just splitting for no reason along the seam. And fraying on the edges. I am very careful to handle the filter gently when I turn it over daily and soak it weekly. I want one of the old style filters with the blue inside. It seemed they lasted a lot longer.
