What can I say, having a filter on the frig keeps the ice and water tasting better no doubt. However, having to changeout the filter every six months is like having your oil changed in your car. Cha..ching every 6 months for 30 bucks, I would have given 5 starts if I could buy these filter for under 20 each. But as the saying goes "they got you by the short hairs" and so you must pay.
