Product review (5 stars): These are a great, cheap alternative
Historically, we would purchase the much more expensive GE MWF cartridges. Those cartridges would last 2 months at best before the water supply would slow down to a trickle.

The Supco replacement for GE MWF filters comes in a 2-pack and is still cheaper than a single GE filter. We have been using this Supco filter for a month now, and it works flawlessly. The filter slips into the container just as it should, and produces water much quicker than the GE filter ever could. I have not seen the filter slowing down the water flow as of yet. Each box also comes with sticker labels so you can put the date of installation on the filter.

The packages that the filters come in were not high quality, and the product can easily fall out of the box. This was not a big issue for me, but I can see this bugging some people.

These are a great alternative to the GE filters, and work much better.
