Product review (5 stars): These are good for a year
We used a 3 pack of their 6 month filters which worked perfectly.  Trying this newer one year version.  It installed perfectly and the flow is fine.  I think the GE warning light will come on automatically after 6 months vs. really measuring the amount of water used. The instructions say that if that happens then reset the button [for 3 seconds] to start the clock again.
