Product review (3 stars): But the new filter is OK and was easy to install and then uninstall
The appliance has a "replace air filter" alert activated two-three months after the new refrigerator was first put into service.
This seems to be a recurring alarm based on elapsed time since reset and not the accumulation of what ever filtered particles may rend the filter less effective.
When I compared the new filter to the one that has been in the refrigerator for 2 years, I noticed no difference in them. The old one was just as clean looking as the new one. The old one is still in the refrigerator.
But the new filter is OK and was easy to install and then uninstall.
