My wife and I have a martini bar restaurant and we bought a new Manitowoc under the bar ice machine. From day one were using commercial carbon cartridge filters for the ice maker and the soda system. The system was C Pure AQUAKINGPSC10. The filters were cheap enough and we changed twice a year or so but we could never get rid of the calcium build up in the drain system of the ice maker. About every 3 to 4 months we would have a flooded floor where the ice maker drained the excess water out and it could not pass due to the calcium and it would run out the bottom. After a service tech showed the the issue, we cut a hole in the back were we could put draino in the small water catch and this would keep it clear. A real pain honestly but it was a solution. We just got used to the process. Then I noticed a lot if chain stores were using 3M at their ice machines so I decided to try this one. The cartridge cost was my only issue but I figured it might be worth a try. I installed the unit in August of 2020 and there has never been a calcium build up since. I decided to add the same system to the soda gun system which is the image shown. I change the filters once a year now and have no issues. Clearly a superior system to my previous cartridge system I had used for 4 years. I just ordered another one for my new spare ice machine. I will not be without 3M for my ice equipment again. The only thing I would suggest is installing a purge valve as shown in the picture if it is not going under a sink or some place that you cannot run some water through it. The cartridge does have some carbon that blows out quickly but it will give you gray ice if you don't purge it.
