About this item

    This fits your .
  • Make sure this fits by entering your model number.
  • 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 up to 95% of sediment, rust, pesticides, herbicides, industrial solvents, VOCs, 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 easy DIY installation. With 1” NPT inlet / outlet and Big Blue 20” x 4.5” filter cartridges, the system has minimum impact on water flow (up to 15 GPM) and requires minimum maintenance.
  • Top-Notch Quality: The first stage high capacity polypropylene sediment filter is able to achieve filtration down to 5 microns. The second stage CTO Carbon Block filter is made of high quality coconut shell carbon for maximum filtration efficiency and filter life. Both are tested by an independent third-party to meet NSF/ANSI standards. Both filters have a capacity of 100,000 gallons of water, enough to supply a family of four with clean water for a full year.

Product description

The WGB22B whole house filtration system is the ideal "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 high-capacity 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 more effective than other forms of carbon in that it is finely ground up carbon packed into a solidified block. This means they have a higher density than other types of carbon filters, and are therefore more effective in removing their targeted contaminants. The carbon block filter knocks out bad tastes and odors, removes up to 99% of chlorine from the water, and is highly effective on organic chemicals (VOCs) like 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, which has an iron and lead reducing filter - 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.

5.0 out of 5 stars Definitely improved the quality of our home's water supply!
Reviewed in Canada on December 4, 2017
We had the kit installed by a professional plumber and recommend it be done that way. This filter connects to the main water line so any issues with a DIY installation could be disastrous. Like a few other reviewers, our iSpring WGB22B had a leak between the 2 filters. iSpring immediately shipped us another kit (without filters) but the wall bracket was bent. I am giving this 3 stars because there truly is a noticeable difference in the taste and quality of the water after installing the iSpring WGB22B even with our clean water here in Montreal. I was skeptical about noticing any difference but it is definitely noticeable. However the fact that the first one leaked, and the second kit had a dented bracket makes we worried about the overall quality control at iSpring. I will be placing a water leak sensor underneath the filters just in case more leaks develop. To summarize, the filters definitely improved our water.

Update 5 months later: I am giving the iSpring system a 5 star review as it really improved the quality of our water. Everyone who has tasted our tap water notices how the water is refreshing and doesn’t taste of anything (at all!). We got in contact with Nick at iSpring who promptly helped us resolve the leak issue mentioned in the initial review and the system has been working perfectly since. This kind of direct customer support is rare and we really appreciated it. I added a picture of our installation and a filter to show how massive they are. Another reason for the 5 stars is that we did not notice any drop in water pressure at all. It’s a simple system but well designed and does the job!
