Product review (5 stars): I put it in my Kitchenaid refrigerator about a month ago - installed just like the old blue and orange filter
Not sure why others have had issues with this filter.  I put it in my Kitchenaid refrigerator about a month ago - installed just like the old blue and orange filter.  I ran several liters through it, then it was good to go.  Have had no problems and I think the flow is slightly better with this filter.  If I run into any problems I will re-visit this post.  So far so good - water tastes great.
