Main Features

The iSpring WGB32B comes with numerous advantages that make it both a good investment and the right filter system for households. Apart from the high quality materials used in constructing the system, there are several unique features of this product that makes it useful for everyday life:

High Performance

The iSpring WGB32B provides excellent purification of water supplies in urban areas.

Though this product is mainly developed to remove chlorine, VOCs rust and sediments, which are major impurities in city and municipal supplies, it can also remove other contaminants like heavy metals.

The rated efficiency of the iSpring WGB32B is 95% contaminants removal, which makes the system an ideal solution for producing clean water in your home all through the year.

Easy Installation

Installing most whole house water filter systems usually present a challenge for many homeowners. However, this is not the case with the iSpring WGB32B. As long you’re a bit handy and good with DIY projects, it shouldn’t take you much to set up this unit.

Each component of the unit is coloured and labelled which makes it very easy to fit and match them. A detailed manual with step-by-step instruction is provided to make the installation a breeze. However if you are not confident enough, then consider hiring an experienced plumber to do the job. Don’t worry; it will cost you only few bucks.

Highly Efficient

Depending on the contaminants in your city water, the iSpring WGB32B might just be enough to solve your problems.

This unit comes with a high capacity polypropylene sediment filter which provides adequate filtration of your flush water down to 5 microns, which isn’t bad. But then, this also implies that pollutants of particle size less than 5 microns such as pesticides can still pass through the filter.

However, not all water supplies contain pesticides or impurities with very small particulate size. This is why you need to find out about the contaminants present in your supply before making a final purchase decision.
