Product review (1 stars): Not the qulity I expected.
The filter received is not an NSF53 filter.  It claims to filter out ibuprofin and progesterone.  This filter should filter out mercury and lead. The filter on the Amazon website states it meets NSF53 standards: This filter only meets NSF42. There is a HUGE difference. This is not the $44.73 filter I paid for.  I'm returning it today.  Compare my picture to that on the Amazon website
