Review on Optimize Water Quality with Green Label Replacement Multi Stage Filtration Filtration by Mark Kolipano

I give 4 stars because of the price. Works great on our filter system. Your prices keep going up. I ordered them and wanted to buy them monthly because they work great and the price was great. But in the last 4-5 months the price keeps increasing. We change our filters monthly but at this price we can't afford it. When I started buying them they were great for the price we needed in our monthly budget. Now I have to wait and change our filter every two months instead of monthly due to the price increase for these filters. We will buy filters at a cheaper price that we can change monthly. They work great.
