Product review (3 stars): Know the differences from Original and Replacement
This is a good replacement filter, BUT you need to know that has some differences from the original.
The replacement are not EPA certified for cyst filtering, And the original are approved by EPA to filtering SOME prefiltered CYST. This is a huge difference that can be reflected on your health. The explanation for this is that the Original filter has tiniest filtering pores and also active carbon. The replacement only have active carbon wich help reducing sediments,chlorine and odors also can improve the taste.  Another difference is on the operation of the filter, the pressure of the water with the replacement is fluctuant because do not have the same pore size as the original and this is reflected when you take water from the fridge door.

For me I prefer the replacement because is 50% less expensive and also I had a prefilter for the home main water pipe. And of course is better the replacement filter than using an Expired Original.
