  • Once I figured out that I needed a flathead….
I got the 4 filters. It was actually super simple to replace everything. The only part that I didn’t know how to do was to get the connection fittings off of the one filter to put on the new one. I finally found a video that showed me; you just use a flathead screwdriver to hold down the little ring, and then you can pull out the tube. The new filter already has the insert part that holds everything in place, so you just push the connector into there. Other than that hiccup, it was pretty easy. I turned to water back on to drain it out, and, so far, no leaks! ... show more

  • NOT the filter you want for Reverse Osmosis
Pay very VERY close attention to the specifications and certifications when buying any filter, but especially when buying reverse osmosis filters. If you're running a reverse osmosis system it's safe to assume you need a very high level of filtering to remove specific contaminants. In my particular situation I need heavy metals removed. These filters are NOT certified for that.. ... show more
