Product review (1 stars): Over priced gimmick not worthy of another purchase.
Using a TDS meter the desolved particles went from about 450 to 395 PPM with the GE filter. This is not enough to justify another purchase. Just for comparison my Zero Water drops the desolved particles to 0.0 PPM. The Zero Water also tastes 100 times better. ( Zero Water is like Brita only the filters work better)

This is what I do: As you know all of these filters are expensive including the Zero Water. So, I purchase cheap $1 bottled water that has a desolved particle reading of 25 PPM. I filter it through the Zero Water. The low 25 PPM water does not clog up the Zero Water filter so they last 10 times longer. After 3 1/2 months I am still getting readings of 0.0 PPM on my Zero Filter. I have completely given up on using the GE filter for drinking water and I will replace it with a cheaper after market filter in the future.

In conclusion, the GE MWF only reduced my water particulate by about 55 PPM which makes this over priced piece of junk worthless.
