Have you noticed that your refrigerator's ice maker is making ice cubes that taste bad or smell funny, this is a fairly common problem in ice makers.
One possible cause for ice that isn't quite right is a dirty water filtration system filter. If your filter is older than six months you should go ahead and replace it since that is about as long as they are designed to work properly. In fact, if your family uses a lot of ice you may need to replace the filter at more frequent intervals, because the more water the filter has to purify the less time it lasts.
You may want to order a few extra filters to keep on hand as well, luckily filters are not terribly expensive and can in most cases be ordered online.
