    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 WGB32BM whole house system after your water softener 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 WGB32B 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 WGB32B. For removing the common contaminants found in the majority of municipal water supplies however, the WGB32B fits the bill.


    Q: How does this filter remove iron in the water? Does 3ppm to 0.01ppm apply to any water source?
    A: It depends on the quality of the source water. If the source water has a higher level of hardness, normally with TDS higher than 700, the resin in the filter could be saturated by Calcium, Lead, Magnesium and other cations, and would not be able to remove iron and manganese effectively. In this case, please install it behind a Water Softener that can either remove or neutralize these cations first in order to extend the lifespan of this FM25B iron manganese removal filter.


    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:

    The WGB32B-KS whole house filtration system is a "point of entry" filtration system for cleaning up well water. Unlike "point of use" systems (like a reverse osmosis systems) which only filter water for a specific faucet, the WGB32B-KS passes all source water through a three stage filtration process before sending the freshly cleaned water to every part of your home.

    Each of the three stages of filtration offer a different level of protection. The first stage housing holds a 5-micron polypropylene sediment filter that removes dirt and various larger-sized particles from the water that can clog the following two filters. The second stage of the WGB32B-KS has a GAC+KDF filter designed to remove chlorine, lead, mercury, hydrogen sulfide, heavy metals, pesticides, herbicides, odors, and other contaminants from the water. The third stage of the WGB32B-KS houses a 5-micron CTO coconut shell carbon block filter that knocks out bad tastes and odors, removes up to 99% of chlorine from the water, and is highly effective on pesticides, herbicides, and industrial chemicals.

    The WGB32B-KS is ideal for removing common contaminants and heavy metals found in the majority of well water. If you are on municipal (city) water or another generally clean water supply, the WGB32B may be a better fit for you.
