Product review (4 stars): Returning to Samsung filters
After removing the previous filter, which was not a Samsung Aqua-Pure Plus, I discovered the previous one (not a Samsung) had not been completely locked into place, therefore rendering it useless for 6 months--no wonder I was unhappy with the water taste.

The only reason I didn't give this filter a 5-star rating is because it is harder than hell to install. Getting the filter into position in preparation for turning it is not a problem, but to make the quarter right turn to lock it into place , you have to have Herculean muscles. I was afraid I was going to break the filter cover. All of that being said, I used Samsung Aqua Pure Plus filters in the early days of this refrigerator and was happy with them. I went back to Samsung after spouse complaints about the taste of the filtered water with non-Samsung filters.
