If the municipal water supply is ok, why use a water filter in the
fridge? It's just guesswork to figure out how often to change it -
would water from a non-working filter be worse than unfiltered water?
Also, does it filter the water going into the icemaker?
Thanks!
You want a water filter in you refrigerator because you want to
filter the water that comes into your house. Water pipes can
have all kinds sediment in it. Scale from older pipes can get
into your water. Water in some locations has stuff like iron
and calcium in it. The second reason is for taste. A good
carbon filter can clean up the off taste that many city water
supplies have, and cover up the chemicals.
Yes, the filter takes care of the icemaker. Yes, a non-working
filter can be dangerous. A filter can block benzene from
passing, and if that filter would to break due to pressure
building up from being full of debris, you can get a slug of
benzene and really do some damage. That is what happened to
Perrier when they had their recall.
An even better solution is to get a reverse osmosis system
for under your sink, and then a 3 stage filter. This way, you
get rid of much of the bad stuff, and you have water at the
sink that is filtered. Using larger filters under your sink
means that they last longer, and you don't needlessly use
your expensive filters in the refrigerator. You may also
want a U/V filter to kill off any biologicals that come down
the water line. People die every year across the US from
biologicals in the water.
Even if you have a bigger filter under the sink, you still want
to keep a filter in your refrigerator. That becomes a polishing
filter that the final job on your water, resulting in good tasting
and very clean water. If your ice cubes are not clear, remember
that the junk that keeps your ice from being clear ends up in
your body if you don't filter it out.
