iSpring WCS50KGRO5004F, Whole House Water Softener & Under Sink Reverse Osmosis Water Filtration System, Reduce PFAS, TDS, and Lead, Complete Softening and Purification Solution for the Entire Home

The iSpring WCS50KG and RO5004F bundle delivers a complete water solution for your home, combining whole house softening with advanced under sink purification. The WCS50KG whole house water softener removes hardness minerals, preventing scale buildup in plumbing, appliances, and fixtures while extending their lifespan. Its advanced control valve automates backwash and regeneration, with user-friendly features such as low salt reminders and vacation mode. The RO5004F under sink reverse osmosis system features a 6-layer filtration process that removes chlorine, taste, odor, sediment, and up to 99% of over 1,000 harmful contaminants, providing pure, great-tasting water for drinking and cooking. Its compact design saves space, and the modular filter structure makes replacements quick and easy. A water softener replaces hardness minerals like calcium and magnesium with sodium (or potassium) ions through an ion exchange process. While this effectively prevents scale buildup, it also means your softened water contains added salt, which is not ideal for drinking or cooking. That’s why it’s important to pair your water softener with a point-of-use (POU) reverse osmosis (RO) system. An RO system removes the sodium introduced by the softener along with other dissolved solids, ensuring your tap delivers fresh, great-tasting, and low-sodium water. In short, the water softener protects your plumbing and appliances, while the RO system ensures the water you consume is as pure and healthy as possible.
