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 WGB32B filters your water from the source. This means water from every output in your home or business will have passed through the three filtration stages of the WGB32B. So what exactly do these three 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 and third stages of the WGB32B house 5-micron CTO coconut shell carbon block filters. 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 filters knock out bad tastes and odors, combine to remove over 90% of chlorine from the water, and are highly effective on organic chemicals (VOCs) like pesticides, herbicides, and industrial chemicals.

If you are on well water or have unusual contaminants in your municipal water supply, you may want to consider the WGB32BM over the WGB32B. For removing the common contaminants found in the majority of municipal water supplies however, the WGB32B fits the bill.

Performance

Being a 3-stage system it offers three layers of protection against harmful water contaminants.

The first stage filter protects against the larger particles like sediment, rust, sand, dirt, and heavy metals. This filter uses  multi-layer technology which gives a more gradual filtration, meaning that the filter is less likely to clog up as quickly. Put simply, the outside layer of the filter has bigger holes (larger micron size), and the holes get smaller as the filter nears the inner layer. This has the effect of reducing clogging of the filter pores which can cause pressure loss. It also means your filters will last a bit longer. This filter offers protection down to 5 microns, meaning that only particles smaller than this will pass. This is about as good as it gets for whole house water filters, which are not as refined as reverse osmosis systems. The Aquasana Rhino is offers the best protection in a whole house unit (down to 0.35 microns). Five microns should suffice in most areas, but if you have problems with pesticides then I’d recommend something a bit more refined.

The second and third stages of the filtration process use carbon block filters. These work to remove further pollutants from the water, and also to refine the taste and odor. They are more effective at removing chlorine and organic chemicals. These two filters are exactly the same, and doing so keeps the running costs low. However, these big blue 20″ x 4.5″ filter housings are standard among many different filter systems. This means there are a variety of different filters available, allowing you to pick and choose and customize your water filter combinations. This system comes as standard with one sediment filter and two carbon filters, but if you wanted you could add a pH filter in place of a carbon filter to balance the pH. This idea of customization is a great selling point of this system, and allows you to tailor your filters specifically to your water problem.

Update: This 3-stage water filter is now available in 3 different filter configurations. There is the regular carbon filter that we have just mentioned, and now two specialist versions. They deal with heavy metals like lead, copper, and iron. The carbon version is great for municipal water supplies, while the heavy metal filters are well suited to well water supplies. Take a look at how the 3 systems compare in the table below:

User Reviews

Review 1

We have had this filter installed now for about 5 months and we absolutely love it. I have a family of five and we live in a five bathroom home with 1 kitchen and a bar. We have well water on our homestead and we installed the 1 Inch Rusco / Vu-Flow 100 Mesh Spin Down Sediment Water Filter as directed in the instructions to help with filter maintenance. I did upgrade the filter cartridge in the 1 inch Rusco with the 200 mesh (74 mic) for 3/4 or 1″ Spin-Down to handel Fine Sediment. This allows us to catch and wash away the larger particles in the water without clogging up the 5 micron 1st stage filter of the iSpring. We often have 2 showers going with a load of laundry and the dishwasher going. To this date we have not experienced a loss of water pressure. Our water is so much better now, it smells better, taste better and just looks cleaner. I feel good about letting this device treat the water for my family.

Style: Fine Sediment and CarbonVerified Purchase

Great product. There is a very noticeable difference in water quality, from drinking to showering to washing clothes and dishes. The product is large, so make sure you have the room to accommodate it. I added a shutoff valve on the water main before the filter, added a regulator (our pressure was 150psi! The filter's range is 40-90psi. I set mine to 65psi.), installed a water pressure gauge just after the regulator, installed a bypass for the system (just in case), then another pressure gauge to help monitor differentials before and after filter (should help determine when its time to change the filters), and then finally another shutoff valve after the system so that the filter can be isolated for filter changing or other maintenance (with only a shutoff valve before the filter, be prepared for all the lines in your house to drain back to the system).

Its a project and requires some know-how… expect to spend several hours on it, especially if your situation is similar to mine (my water main came in to the house in the worst spot in the crawlspace, so I rerouted it so that its closer to the entrance.). If it seems daunting, I would get a professional to install it for you.

But again, its a great product and a great investment in your home. Well worth it!

I always like to start these with the positive… the system has performed very well to filter the iron and manganese from my well water which is what I needed it to do. And yes, despite some problems I would buy it again. Now the rest of the story… when I received the first one, the packaging was missing the entire 3rd canister and the iron/manganese filter cartridge. Since it is shipped with the 3 canister heads pre-assembled and attached to the mounting bracket, there was no way to hook up only part of it. Amazon took care of that immediately with one phone call. (Nice job Amazon, as always!). When I received and hooked up the new system it was quite easy. I am a DIY homeowner and am not afraid to tackle most anything. I aready had a whole house sediment filter in place (0.5 and 1.0 micron filters removed most of my reddish color) which I will continue to use. But I still had problems with discoloration in the appliances and laundry which forced me to add the iSpring system. But I digress…, when I installed and pressurized the system I had a serious leak on top of the canister head of 1 unit. I switched heads with the first system that I had not yet returned and it was worse. Two of them were leaking. Upon closer inspection I found that it was actually not the canister heads per se, but was the red push-button pressure relief valve that is used to relieve pressure in order to change filters. This time I called iSpring and spoke with a very nice gentleman who told me that sometimes the relief valves get loosened suring shipping and that all I needed to do was tighten the Phillips head screw from the bottom to easily correct the problem. This is where they dropped from a 4 or 5 star rating to only 2. He was Johnny on the spot with the correction so this let me know that it was a known problem. I actually had to take it apart 3 times, re-tighten the screws, finally holding the red button gently with a pair of pliers while tightening and then wait 6 days for it to slowly stop leaking. I doubt the story about loosening during shipping as there was NO internal or external damage to the packaging of either unit. Since it is obviously a known problem, and there have been leaks mentioned several times in other reviews, then I would have expected this problem to have been resolved a long time ago. Come on iSpring, put a durn o-ring in the assembly or something and take care of this nuisance once and for all. And by the way, once the correction is developed, send all of us a modification kit so we can stop worrying about coming home to a water leak. My leak was about 2 quarts a day.

Overall I am happy with the filter system. I installed this in combination with a 50 micron spin down pre-filter and a downstream iSpring UV sterilizer. I have a dug well which has the potential for surface water contamination and I feel very comfortable drinking the water from the tap now.

The 1″ FPT inlet and outlet didn't seal too well for me. I have a small intermittent drip from the outlet. I installed the spin down filter directly into the inlet which is a terrible idea. iSpring say you can do it, but it makes it so close you can't get the filter wrench on it. Also, the threads on the spin down filter are very short and were difficult to get sealed into the filter housing.

Conclusion

The WGB32B-PB version is the most expensive, but it is one of the most effective whole house systems for treating well water supplies. It can deal with water that has high levels of sediment in it, while at the same time removing dangerous heavy metals like lead and mercury.

The cheaper WGB32B is perfect for city water supplies. The 2 carbon filters are great at treating high levels of chlorine.
