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 95% of sediment, chlorine, rust, 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 WGB21B-PB whole house system after your water softener to achieve ideal 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 WGB21B is the system to go with. Naturally occurring metals are commonplace in most well water sources, however, and that is where the WGB21BM or WGB21B-PB earns its keep.
If you are on well water or have heavy metals such as iron and manganese or lead in your municipal water supply, you may want to consider the WGB21BM(iron and manganese reducing) or WGB21B-PB(lead reducing) over the WGB21B. For removing the common contaminants found in the majority of municipal water supplies, however, the WGB21B 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.

80,000-gallon capacity replaceable highly compact coconut shell activated carbon filter and lead reducing filter provide over half year of clean water for your entire family.

This whole house system removes up to 98 percent of sediment, chlorine, chloramines, chemicals and other contaminants that create color, foul tastes and odors. (Tested by SGS, 2018)

The WGB21B series whole house filtration system is the ideal 'point of entry' filtration system for cleaning up water supplies to a home or business on contaminated municipal (city) water or chlorine-treated well water. (Tested by independent third-party to meet NSF/ANSI Standards: 42, 53 for drinking water treatment units, 2018
Product Features
Style:Fine Sediment and Carbon
The WGB21B series is a great "point of entry" filtration system and an excellent alternative to the larger WGB32B series (4.5"X20") for smaller homes or where limited space may be a concern. Unlike "point of use" systems the WGB21B series will filter water directly from your source. This means that water from every outlet in your home will have passed through this filter, providing up to 80,000 gallons of clean water for the entire family.
The 1st stage houses the 5-micron CTO coconut shell carbon block filter (FC15B). 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 over 90% of sediment and chlorine from the water, and is effective on herbicides, and industrial chemicals.
Our 2nd stage filter (FCRC15B) lead removal filter is specially designed for reducing lead. This filter features a high filtration capacity of 80, 000 gallons of lead-loaded water, reducing lead level from as high as100 ppb to 15 ppb (the EPA standard for drinking water) and less.
If you are on city water, your local water utility must meet very strict Federal and State standards for purity. Almost all municipally treated water is chlorinated, and this can affect the taste and create odors in the water. The WGB21B series filtration system will remove these tastes and odors. If you are on a private well or spring, you should have your water tested.

The system came aligned for water flowing right to left, but the pipe coming into my house is on the left, the rest of the plumbing was on the right. This got fixed easily. I simply removed the bolts, turned the mounting frame around, and installed it to change the direction of the flow. Works great! No reddish stains any more!

Installed this filter without many problems and we are now getting quality water into our house.

Hope it will last a while. The water tastes great!! Installation was fairly simple, as we were replacing an existing system.

My water tasted metallic and left some stains in the tub and sinks. I knew it's time I should get some water treatment systems. Did some research and found this one that fit my budget. Installation was easy than I had thought. It's been in my house for over a month and I can clearly see that water quality has improved a lot!

As someone with zero plumbing, I installed this sytem in 2 hours: 15 minutes for reading the literature and/or video, 10 minutes for setup of tools and cleaning up the area, 1 hour for the installation, and 20 minutes for checks after the install. We purchased this because we want an efficient way to treat water coming into our house and I know our well water has high levels of lead in it.

We used to find hints of iron and lead in our well water; started to take it seriously after the Flint water crisis. Got this iSpring 2-stage whole house system as it fit our budget. Easy to install. The brownish stains are gone. So if your looking to pick this up for your household, go for it you can't go wrong picking this system.

I tried that filter that hooks straight to the main valve next to the water heater tank and that is neat. My tap water is clear and directly drinkable. Convenient.

We have small kids in our house. Want to ensure that our water is safe for drinking and daily consumption. Our pipe system is aged. I know that pipe corrosion may add copper, lead, and other metals to our water. Found this system that fit my budget and could treat water coming into my house. Very satisfed with the results. Love that this water filtration system can help keep me and my family safe.
