iSpring WCB32C 3-Stage Whole House Water Filtration System w/ 20” x 2.5” Oversized Fine Sediment and Carbon Block Filters
About this item
- [Protect Your Family and Household Appliance from Sediment, Chlorine, and More] Say goodbye to smelly, bad tasting water! Our system removes up to 99% of chlorine from water as well as sediment, rust, pesticides, herbicides, industrial solvents, and various other contaminants. This system is installed at the main water supply line in order to treat all the water in your home.
- [DIY Installation and Maintenance] Refer to our manual and our helpful YouTube videos for DIY installation. With a clear housing for the first stage, you can easily tell when to change the filter. The cartridges are individually wrapped to ensure freshness. Please unwrap the cartridges before use.
- The first stage polypropylene sediment filter is able to achieve filtration down to 5 microns. The second and third stage CTO Carbon Block filters are made of coconut shell carbon to increase filtration efficiency and extend filter life. Both are tested by an independent third-party to meet NSF/ANSI standards. Both filters have a capacity of 30,000 gallons of water, enough to supply a family of four with clean water for half a year.

- [Please Note] Unlike an RO system, this system will NOT reduce Total Dissolved Solids (TDS). If you are interested in a filter that removes TDS consider our iSpring Reverse Osmosis (RO) systems.

Frequently Asked Question
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 WCB32 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. Please consult iSpring professionals prior to purchase if you are unsure of which product will meet your needs.
