    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, 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 WGB22B 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 WGB22B is the system to go with. Naturally occurring metals are a commonplace in most well water sources however, and that is where the WGB22BM or WGB22B-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 WGB22BM or WGB22B-PB over the WGB22B. For removing the common contaminants found in the majority of municipal water supplies however, the WGB22B 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 Features


    Style:Fine Sediment and Carbon

    The WGB22B 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 WGB22B filters your water from the source. This means water from every output in your home or business will have passed through the two filtration stages of the WGB22B. So what exactly do these two 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 stage of the WGB22B houses a 5-micron CTO coconut shell carbon block filter. Block carbon is finely ground up carbon packed into a solidified block. It knocks out bad tastes and odors, removes up to 99% of chlorine from the water, and also removes pesticides, herbicides, and industrial chemicals.

    The WGB22B is intended for lightly contaminated municipal water. If your water is highly chlorinated (to the point where you can smell, taste, and/or feel it), the WGB32B will be your best option as it has dual CTO carbon block filters to provide additional filtration measures. Alternatively, if you are on a well water source, you will want to take a look at the WGB32BM and/or WGB32B-PB, which have iron and lead reducing filters - great for the plethora of heavy metals found in most well water sources. For standard municipal water that hasn't been heavily chlorinated, however, the WGB22B is a great choice.
