Review on Ronaqua Sediment Cartridge Filtration Polypropylene by Gerald Duncan

These are quality devices that work as advertised and are sure to make the reverse reading system successful. I would wholeheartedly recommend doing 3 in a row though depending on your settings. 2 in a batch for me working 24/7 only lasts 3 months using 550ppm Michigan well water. If you have city or municipal water you probably won't need to change filters for a few months, but if you struggle with well water like I do, you may need to think about a pre-filter before two or just buy it in bulk. and change filters every few months.
