I love this filter because it is much cheaper than the PUR #4396918 filter that I used to get for my Whirlpool refrigerator.  This filter fits perfectly and it is easy to install. I am looking at the box of the filter, it said "One Purify LLC , 6725 S. Fry Road, Suite 700-298 , Katy, TX 77494.  So I am not sure if this is made in USA or China. At the bottom of the box, it also said "Made in China". I hope the box is made in China only , not the filter.
Things made in China usually have no quality control. So I really hope that this is made in Texas.
The water tastes fine and pure after I change the filter but the filter weigh a lot less than the PUR filter that I used to have. The PUR filter is much heavier.  I am not sure if that will affect the water quality and the filter ability.  Anyhow, I just purchased 4 of them, so hopefully they are not made in China and I will keep buying them in the future.
