We just installed an Aqua Rex WK1 water conditioning system on a mist system. They previously had a GE Merlin Reverse Osmosis system which was a tankless RO System that had horrible reviews. GE discontinued the product not too long ago due to issues such as constant draining which is what we were experiencing here. I installed a Water filter and the Aqua Rex WK1 to alleviate the mist system of sediment, VOC’s and scaling. The Aqua Rex system has great reviews and after talking to a few people that have both installed them and purchased them, they are quite a good product. Its an easy and affordable solution to limit the scaling and buildup of minerals in a water system.
