LOL! I hear you. Actually, I don't disagree with you at all. I was only
pointing out the premise of their recommendation. Let's just say that the
indicator light is for "dummies" and it's probably best that people who
don't have a clue follow the prescribed recommendation. For those who can
perceive the difference in flow and/or taste, then that is probably the
As to the "two week" recommendation, that is as much for health reasons and
CYA as anything else. When the filter doesn't have a frequent flow, in
certain environments it is possible for bacteria or other organic
contaminants to multiply.
Back in the late 1960s, the Heater Division of Eaton Corp. developed one of
the first activated charcoal water filters for residential contertop use.
The activiated charcoal cartridge in this filter was significantly larger
than any of those currently installed in refrigerators. Their general
recommendation in their literature was to change the cartridge annually.
Just my 2 cents.

Whirpool has developed a new fridge that only tells you when the filter
really needs to be replaced. It has a differential pressure guage and
does random sampling to make sure the purity level is within spec. When
it detects something odd in the water, it uses a built in internet
connection to connect with the Whirlpool testing and engineering
department for further analyis and, if the levels are bad, they will
give you a personal phone call to explain it to you and let you know you
need a new filter and where to buy one. This additional stuff makes the
refrigerator cost about $2000 more than the other ones. But for you
people who don't think the 6 month timer is good enough and ends up
wasting filters, maybe this new fridge is for you. Perhaps in about 60
years it would pay for itself in filter savings.
