The iSpring WGB32B 3-Stage Whole House Water Filtration System

If you are looking for the best whole house water filter , you should consider buying the iSpring WGB32B 3-Stage Whole House Water Filtration System. All of us are going to be happy with a product that makes our lives better and this is what the iSpring WGB32B 3-stage whole house water filtration system will do. It is able to take a variety of impurities from the water and these include dissolved pesticides, rust, chlorine, and sediments.

Having these in the water can make it dangerous to drink and can also cause damage to any machines that the water goes into. This filter can change that and provide you with clean, safe water regardless of what it is being used for. This happens thanks to the 3-stage filters with micron ratings of 5, 5 and 1. As a result, there will be 96% cleanliness of the water. The first filter is a polypropylene sediment filter while the next is a CTO carbon filter. The small micron number means that the smallest of particles could be kept away and little or nothing can get through.

Key Features

Cleaning Ability

The system can remove all of the damaging items from the water. The inlet/outlet is 1inch NPT so there is not a lot of impact regarding the flow of the water. This flow will be as high as 15 GPM and overall the system will not need a lot of maintenance. You will not have to go to a lot of trouble to have access to clean water.

Filter Cartridges

The connection is made to the water supply that services the whole house. From then on, all taps will provide improved water. The filter cartridges used are Big Blue 20 inches x 4.5 inches, so there is not a great loss of pressure plus there is a long filter life.

Total Dissolved Solids

These will not be reduced and the water will be kept full of the healthy minerals that we want to have in the water. You lose what you do not need and are able to keep what you do need.

Filtration Stages

Filtration at the first stage will be as low as 5 microns. The last 2 stages are CTO Carbon Block filters and provide the highest level of filtration, thanks to the use of coconut shell carbon that is of a high standard. NSF/ANSI Standards are reached after tests from a third party. 100,000 gallons of water each year can be filtered to provide safe water for a household of 4.


  • You can get a years’ clean water thanks to the 100,000-gallon capacity of the easy to replace the filter.
  • Provides enough pure water for a family of 4 members.
  • Every item in the house that uses water will have around 98% of the sediment taken out of it.
  • A third party carried out the tests to check how good the filter is and it was found to meet NSF/ANSI standards 42 and 53 for clean drinking water.


  • If you do not have a lot of knowledge when it comes to plumbing, you may find it a little bit difficult to install.

Frequently Asked Questions

How can I replace both types of filters?

The iSpring water systems website will have all the details you need. You can sort out what you need by Big Blue.

How do I attach the iSpring WKB32B to the inlet?
