Product review (3 stars): Not as described
I found the exact same things Robert mentioned in his comment on July 14. These filters do not have the NSF Standard 53 rating and the filter says 300 gallons. I wish I had read Robert's comment before I ordered. I'm sure they work great for taste and they installed as they should, but they aren't the filter the description states. I do love the price, but I will look for the better filters next time and send them back if they are described falsely as these are.
