Product review (5 stars): Cut one open, internally it's same as GE specifications
The whole debate over certifications had me curious to see if they were offering a lower quality product or just didn't pay to be certified in all available tests. Its an expensive process so its not surprising an off brand might opt to bypass that option. I cut one of each open to compare my GE MWF to this one and they are very clearly using the same filtration methods and specifications GE designed for this filter.

Buy what makes you feel the best about your purchase but I can tell you first hand that this is just as safe as the GE branded filters at less than half the cost, I'm switching and not looking back. Overpriced name brand products are all too common, and these generic replacement filters are made in the USA instead of some place like China which you would expect, so I'm pleased to start saving money and actually buy something American made for a change.
