Product review (4 stars): Removes MORE SOLIDS than GE
Good alternative to the brand name GE MWF filter, fit well with no leaks and I've used one for several months before replacing again. I have used both the GreenPureFilter and the brand specific GE MWF filter and used a TDS meter to analyze the total dissolved solids in the water and compare their filtration capabilities. To start, our tap water isn't the worst to begin with, rating around 148. After using the GreenPureFilter for 2 months it scored 111 on the TDS meter and the brand specific GE was 138! This isn't exact and would vary greatly depending on your water quality but our taste comparison tasted identical and according to the TDS meter the GreenPureFilter actually works better and for half the price of GE.
The only reason I didn't give it 5 stars, well after testing both filters I found that I was somewhat disappointed with the refrigerator filters overall and I now have a ZeroWater dispenser filtration system that we keep inside the fridge, which the 5 stage filter reads 00 on the TDS meter and tastes wonderful (who would have thought that 'nothing' would taste so good). I do continue to run the water through the fridge filter before putting it in the ZeroWater dispenser to extend it's filter life though!
