Product review (1 stars): It's not a GE MFWP Filter....thoses certifications mean nothing.
From what I can tell it does not filter Mercury, Pesticide (Carbofuran), Pharmaceuticals (Progesterone, Trimethorprim, Fluoxetine, Atenolol, Ibuprofen), Particulate chemicals (Benzene, P-Dichlorobenzene). Since most of this is found in your water supply, curious why you would waste your money?
