Product review (3 stars): this filter has been replace with the MFW P
This has worked well with my refrigerator.  I've got an indicator telling me when to replace the filter.  We've had the refrigerator for 13 years and it's still going good except the ice maker stopped working.  They replaced this filter with the MWF P because this filter may cause a problem with the ice makers, so we have to replace the water filter and it's too late to send this one back.  Oh well, hope this helps someone else.
