Product review (4 stars): Good Filter - Lasts as Stated by Manufacturer.
This is a really good filter, I get every bit of 6 months+ use. I use one and a half times the recommended amount of water to pass through the filter after installation. I am sure it's fine if you use the recommended amount but to my taste buds, the water tasted a little weird. Flushing through extra water solved the weird taste. Also, I use a Sharpie to mark the date when the filter needs replacing. No need to put a reminder anyplace else.
