iSpring WGB32B 3-Stage Whole House Water Filter

iSpring WGB32B 3-Stage Whole House Water Filter Review

The iSpring 3-stage whole house water system connects to the main water line coming into your house, ensuring all the faucets and showers produce clean filtered water.

The system uses three filtration levels to remove sediment, rust, chlorine, and chemicals.

If you’ve been noticing sediment deposits in your toilet bowl and sinks, you want to get rid of the chlorine taste in your city water, or you are simply concerned about chemicals being present in your water, then this filter is just for you.

If you receive well water, there are two other configurations available: One for iron and manganese removal and another for lead and iron removal.

Read this complete iSpring water filter review and decide whether it is the right one for your home.

Filtering Performance

ispring water filter

1st Stage: Sediment Pre-filter 

The first housing contains a 5-micron polypropylene filter that catches sediment and other large particles.

5 micron is pretty small. Even the finest of silt and sand can’t get through the first stage.

In addition to improving purification performance, the first stage fulfills another important role; it protects the other two filters down the line.

Since the carbon filters don’t have to handle any sediment, they last longer before you need to replace them.

2nd Stage: Activated Carbon Filter 

If you hate the chlorine taste of your city water, this is where the magic happens to ensure your water tastes fresh and pure.

Activated carbon reacts with the chlorine in the water, eliminating most of it. The carbon can also remove chloramines, which some cities use instead of chlorine.

But that’s not all this filter does.

Its highly porous structure also traps molecules of chemicals and some heavy metals. This makes your water safer to drink and cook with.

3rd Stage: Another Activated Carbon Filter

The iSpring system produces twice-filtered water that is cleaner and fresher-tasting.

The second coconut shell carbon block removes residual taste and smells from the water.

The two carbon filters combine to remove over 99% of chlorine in your water and reduce a wide range of organic chemicals from herbicides, pesticides, and industrial pollution.

You’ll notice the difference in your water quality and taste almost immediately after you install the filter.

To verify that the filter is working, get a chlorine test strip – you can get a pack for $10 or less – and see how much chlorine is left in your water.

 Over time, you’ll also notice that your surfaces no longer have any stains.

Installation & Maintenance

If you have done some DIY plumbing projects before, you can have the system installed in a couple of hours.

But if you are busy or don’t trust your plumbing skills, get a plumber to install it properly.

Either way, you’ll need to get a few extra fittings and connectors to finish the installation.  

The first thing is to pick where the filter will go. It should be on the main water line after the water meter. You want all the water coming into the house to pass through the filter.

Once you identify the right spot, make a T joint such that the water diverts to the filter but can still flow as usual to bypass the filter when you need to do some maintenance (remember to turn off water and drain the pipes).

Mount the filters on the included bracket and link them together through their inlet and outlet ports.

Make sure you use plenty of lubricant or Teflon tape on the connectors to avoid leaks.

When you are done, switch on the water and check for leaks.

The maintenance is bit easy. Other than occasionally checking for leaks, you simply have to wait until it’s time to replace the filters.

This can range anywhere between 6-12 months depending on how much water your family uses.

A good way to tell when the filters have gotten too clogged is to install two pressure gauges; one before the filter and another after.

Because the iSpring filter has a high flow rate, the pressure should be just about the same on both ends. If the outlet pressure gauge starts dropping, replace the filters.


What We Like The Most About The iSpring System

ispring water filter review

This is one of the best whole-house filters for municipal water. With dual activated carbon filters, it’s able to remove over 90% of chlorine from the water.

If your biggest issue is the unpleasant taste and smell of chlorine in your water, this is the best whole house filter.

It can also help if you think that the chlorine in your shower water is affecting your skin and hair.

Apart from removing chlorine and chloramines from your water, it will also get rid of sediment, rust, and chemicals.

Another thing we love about the iSpring system is the high water flow. Nothing is worse than having water come out of the faucet or shower in a trickle.

The iSpring uses large inlets and outlets that don’t slow water down.

You will also appreciate how easy and quick it is to change the filters when the time comes. There is no need to take down the whole filter.

You simply unscrew the filter housings, replace the filter cartridges and screw the housing back.  

We also love that they provide multiple options to suit different customer needs.

If you get city water, the main filter with the two carbon blocks is great.

 If you receive well water, chlorine is not a concern. The iron and manganese or the lead and iron filter are the best choices.

What We Don't Like About The iSpring WGB32B

ispring water filter review

The main issue with this system – and this is the case with most whole-house filters – is the amount of work involved in installing it.

This is not like an under-sink filter where you can hook up the filter in less than half an hour. Depending on your level of DIY plumbing skills, it could take anywhere between an hour to four hours.

Most buyers actually just prefer to hire a plumber to install it.

It will cost you more, but at least you'll be sure it's installed properly. Moreover, you won't have to spend a whole afternoon cutting pipes and joining connectors.     

In addition to the hours-long hassles of installing the iSpring system, you may also have to buy some parts yourself.

These include connectors, O-rings and lubricant.

The lubricant is especially important to keep on hand. The filter tends to develop leaks after installation.

 Generously apply the lubricant to connectors during installation to avoid having to take down the whole system to repair a leak.

The iSpring WGB32B Water Filter Is Perfect For You If...

iSpring WGB32B Water Filter
  • You receive city water and want to get rid of the taste/smell of chlorine.
  • You are concerned about chemicals such as herbicides, VOCs and industrial solvents in your water.
  • You’ve been noticing rust deposits and other stains on the toilet bowl, sinks and other surfaces.
  • You receive well water and want to get rid of manganese, iron or lead.
  • You want to filter all the water coming into the house rather than water at only one point.

Avoid Buying This One If You...

ispring wgb32b

Are looking for a smaller point-of-access filter

If you want to filter water coming out of one faucet, don’t spend a lot of money on a whole-house filter. A cheaper and smaller under-sink or counter-top filter will do.

Want a filter that can remove microbes and almost all chemicals from water 

Carbon filters are great, but they cannot remove everything. They are especially poor at targeting dangerous microbes like bacteria and viruses.

They also don’t remove all chemicals.  

If you want to filter most of the bad stuff from the water, you are better off with an under-sink RO filter.

The downsides of RO filters are that they are pricey and significantly reduce water pressure.

But you can also have both systems in place.

Use the iSpring system to remove chlorine and sediment from all the water coming into the house and then install an RO filter and faucet specifically for drinking and cooking water.



Our Bottom Line

iSpring WGB32B 3-Stage Filter

A whole house is a pricey investment. Even more so if you have to hire a plumber to help you install it.

But as numerous buyers of the iSpring 3-stage system have attested to, it’s worth it. The quality of water drastically goes up.

It smells pure, it tastes fresh, and you can forget about constantly cleaning up reddish stains left behind by rust and sediment.

Even the shower feels healthier for your skin and hair.

If you are after a reliable whole-house water filter, we highly recommend this one.

Get the WGB32B model if you receive chlorinated city water, the WGB32BM model if your well water is contaminated by a significant amount of iron and manganese, or the WGB32B-PB model if you are concerned about lead being present in your well water.
