Product review (5 stars): For a small family, lasts better than 6 months
I've been really happy with everything LG made and made-for. This filter probably lasts us (family of 3) a bit longer than six months. Our water is hard and often needs filtering for anything other than daily-use (washing dishes, showers, etc.), but it doesn't seem to speed up our filter use. We use a lot of ice, but less water as we're often either on the go with a bottle of water, or at work/school and using the filtered water there to drink, so I'm not sure our experience is normal. That being said, I think the longest any filter on the refrigerator has lasted us was 8 months. For a family who drinks a LOT of water using the refrigerator filtered spout, it may last a little less than six months.
