Product review (2 stars): Original GE MWF filter compared to many others
After 4 hours of researching brands to replace the MWF GE water filter for my refrigerator I found that none of the brands had the same standard as the OEM brand of GE.  Many had at the most  - an  nsf 42 standard which reduce specific aesthetic or non-health-related contaminants (such as chlorine, taste and odor, and particulates). .. but none had an NSF standard of 53 which  reduce specific health-related contaminants such hazardous contaminants may be microbiological (including filterable cysts), chemical (including disinfection byproducts, pesticides, herbicides, and insecticides), or particulate in nature.  Most didn't list an NSF standard at all they just claim a filtration system that will make your water taste better.  The GE brand has gone up in price a lot which ticks me off and is ridiculous, so that is why I was hoping to find a knock off brand that was the same but cheaper.  In the end I found a site cheaper than the GE site by around $18 and they were the original GE filters.  A lot of time researching which I feel wasted a good portion of my Saturday, but now I know and I guess I learned some things.. and I can at least leave my review for others who may be wondering the same thing.  I ended up getting mine at freshwater.com as of this date Aug 16, 2014 - they were the cheapest I could find online.  I hope some other companies who can make these water filters will do it at the same standard and not charge as much as GE. .. if they do they will make a lot of money on volume selling because i'm sure people would buy them.
