    The filter works great. Easy to replace.

    Amazing filter system. We use our FS10 to run our fridge ice/water as well as counter top water spigot. We typically run a filter for 18months as during the dark years (2020-) we had one around 24months and it became noticeable that it was past due. System is easy to change a filter as long as you have some shutoffs, run some water through allow it to rest and run more through than its ready to go. Have never seen any organic growth one of these filters; opposed to the ceramic gravity filters. Absolutely the best filter system company on the market. Proud to support a MICHIGAN company,
