    Frequently Asked Questions

    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, 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 WCB32O whole house system after your water softener to achieve optimal performance if you have hard water.
    To determine which product best suits your need, it is recommended that you get a professional water test done prior to purchase to identify the main issue of your source 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.


    Q: What type of Whole House Water Filter do I need?
    A: If you are on municipal water that isn't contaminated with heavy metals like iron, manganese and lead, the WCB32O is the system to go with. Naturally occurring metals are a commonplace in most well water sources however, and that is where the WGB32BM or WGB32B-PB earns its keep.
    If you are on well water or have heavy metals in your municipal water supply, you may want to consider the WGB32BM or WGB32B-PB over the WCB32O. For removing the common contaminants found in the majority of municipal water supplies however, the WCB32O fits the bill.


    Q: What flow rate should I look for?
    A: Measured in gallons per minute (GPM), flow rate determines the amount of water available to run your shower, toilet, hot water heater, dishwasher, etc. When calculating your requirements look at the demand ratings printed on your appliances and toilet. Depending on the size of your house and family your water flow rate requirements may range from 5 to 40 GPM.

    Product Description


    Style:All Blue Housing

    The WCB32O whole house filtration system is a "point of entry" filtration system for cleaning up water supplies to a home or business on municipal (city) water. Unlike "point of use" systems (like reverse osmosis systems) that are installed to supply water to a specific faucet, the WCB32O filters your water from the source. This means water from every output in your home or business will have passed through the three filtration stages of the WCB32O.

    So what exactly do these three stages of filtration offer? Used as the first stage of defense on the system, the stage 1 housing holds a 5-micron polypropylene sediment filter. This filter removes dirt and other various larger-sized particles from the water that can clog the following filters. The second and third stages of the WCB32O house 5-micron CTO coconut shell carbon block filters. Block carbon is finely ground up carbon packed into a solidified block. They knock out bad tastes and odors, combine to remove up to 99% of chlorine from the water, and are highly effective on pesticides, herbicides, and industrial chemicals.

    If you are on well water or have unusual contaminants in your municipal water supply, you may want to consider the WGB32BM over the WCB32O. For removing the common contaminants found in the majority of municipal water supplies however, the WCB32O fits the bill.
