ISpring Multi-layer filtration allows for less clogs and minimal pressure loss. ISpring carbon block filter uses high quality coconut shell carbon and highly compact fabrication tech for maximum filtration efficiency and filter life. Knocks out residual bad tastes and odors. Two CTOs combine to deeply remove chlorine, and are highly effective on organic chemicals like pesticides, herbicides and industrial chemicals. Q: With this whole house system, do I still need to install a water softener if my water is very hard? A: Yes, a water softener is needed if your source water has a high level of hardness, usually with TDS higher than 700 PPM. Hard water can reduce the lifespan of whole house water filter cartridges. The harder the water, the greater amount of scale buildup occurs, and the sooner the filters get clogged. This whole house water filter can remove up to 95% of sediment, chlorine, rust, pesticides, herbicides, industrial solvents, VOCs, and various other contaminants that a regular water softener can’t, although it does not soften your water. It is recommended that you install this WGB32B series whole house system after your water softener to achieve optimal performance if you have hard water. Note: Water Softeners and whole house systems usually do not lower the TDS level of the water. An additional Reverse Osmosis system may be necessary for your drinking water. Peak Flow Rate: 15 GPM.
