Product review (1 stars): Beware, you might not be getting the product you expect.
Beware, you might not be getting the product you expect. For years, GE sold the MWF filter. Now they offer two similar-sounding products, the MWF filter and the MWFA filter. Even though I have purchased the MWF filter from this link from Amazon since 2010, this time they shipped me model MWFA. There is a very significant difference. See the manufacturer's link (shown in the photograph). The old MWF filter is being sold as "Pharmaceutical Filtration" while the new MWFA filter is being sold as "Standard Filtration." The implication is that the only difference is the MWF filter also reduces certain listed pharmaceutical compounds, while the MWFA filter removes everything that the MWF does except for the pharmaceutical compounds. This is NOT the case. The MWF filters that Amazon shipped to me did little or nothing to improve the taste of my water. I was not convinced that I could actually get the old MWF filter from this website, so I went to Home Depot and found the old MWF filter (sold as the "Pharmaceutical Filtration" model). I installed the MWF filter and once again my system supplied water with good taste.

If you want the best tasting water, and likely the highest contamination removal, be sure to use the MWF "Pharmaceutical Filtration" model and avoid the MWFA filter. Unfortunately, I don't know if the MWF filter is available from Amazon. If Amazon ships you the MWFA filter and you've ordered the MWF filter, be sure to return it for a refund within 30 days.

Unfortunately, GE jacked up the price of the MWF significantly, so if you've used the MWF filter in the past, expect to pay a lot more for it now.
