Features
- An anti-scale water filter system that protects your pipes and household appliance from scale, corrosion, and more - The FWDS150K patented scale Inhibitor effectively sequesters calcium and magnesium. It also inhibits corrosion, particularly iron, steel, galvanized, copper, and lead, by coating the surface of your pipes. The coating serves as a protective layer that makes it harder for bio-film to form. It also helps to stabilize chlorine as the chlorine will not react with the metal pipe if the coating exists. This water filter has a capacity of 250,000 gallons of water filtration.
- A water filtration system with top-notch quality - WSP50ARB reusable spin down sediment filter with touch-screen auto flushing module is an ideal frontier water filter in whole house water filter system, protecting your entire plumbing system from sediment, rust, dirt, sand, and large particles. The second stage FG25B-KS compound filter is specially designed to remove chlorine, lead, mercury, hydrogen sulfide, heavy metals, pesticides, herbicides, odors, and other contaminants.
- The third stage FC25B carbon block filter is made of high-quality coconut shell carbon for maximum filtration efficiency and filter life. It further reduces chlorine and harmful chemicals, and improves your water taste. Both water filters are tested by an independent third party to meet NSF/ANSI standards. The whole system has a capacity of up to 250,000 gallons of water filtration, enough to supply a family of four with clean water for a full year.
- A whole house water filter with DIY installation and maintenance - refer to the manual and our helpful YouTube videos for easy DIY installation. With 1 in. NPT inlet/outlet and 20 in. x 4.5 in. water filter cartridges, WGB32B-KDS whole home water filter system has minimum impact on water flow (up to 15 GPM) and requires minimum maintenance.

- Please note - This whole house water filter is installed at the main water supply line in order to treat all the water in your home. Unlike an RO system, this whole house water filtration system will NOT reduce Total Dissolved Solids (TDS) and instead keeps healthy minerals in your water; if you are interested in a filter that removes TDS consider our iSpring Reverse Osmosis (RO) systems. The polyphosphate filter does not remove calcium and magnesium from water - it only prevents those molecules from forming scale.
Description
Engineered with durable Dutch-weave stainless steel mesh, our pre-filter delivers superior sediment capture, enhanced strength, and longer service life. Unlike standard mesh designs, it provides more reliable filtration and lasting performance. Packed with 10 lbs of premium-grade Siliphos, our anti-scale cartridge delivers long-lasting protection and superior performance. While many alternatives use only 1 lb of lower-quality media, iSpring provides both higher quantity and higher quality for greater value. Your feedback drives our innovation. iSpring refines every detail based on real user experience — earning 98% positive reviews since mid-2025, far ahead of others. Does this system soften water? No. The WGB32B-KDS whole house water filter prevents scale buildup and protects pipes and appliances from corrosion. It does not remove calcium or magnesium, so water hardness remains unchanged. For softening, see iSpring WCS45KG (B08XW4NXDP). What contaminants can this system remove? Turbidity, visible particulate matter, sand, silt, dirt, rust, chlorine, lead, mercury, heavy metals, hydrogen sulfide, taste, odor, THMs, VOCs, chemicals, herbicides, scale, and corrosion Can I install this system outdoors? Install indoors in a well-ventilated area, shielded from wind and rain, away from direct sunlight and heat. Consider water leakage protection. For outdoor installation, ensure insulation for frost, sun, and waterproofing for both unit and pipes. Can I use this system if my water flow is from left to right? Yes, you can. However, please note that the inlet/outlet marking on the system is fixed, so you will need to flip the machine head to accommodate this setup. To do this, simply unscrew the screws on the machine head and flip it. F3WGB32BKDS FWDS150K FG25B-KS FC25B LS43WL AFLT3

Set name: Sediment
This filter works great! We live in a farm and our water comes from a Well. Sadly the amount of Iron in our water is extremely high and we are always fighting with the brownish color and the terrible metal odor. We were looking for an affordable but effective way to control this issue and after many trials, this filter has been the most effective. It removes the smell completely, and I can finally wash clothes in my house because the water is clean and does not stain my clothes. On top of that, we choose to buy 12 at once to always have it on hand and that makes the price even more affordable. Great product!

Product: iSpring WGB32B 3 Stage whole house filter. Date installed: June, 2022 First Filter change: May, 2023 (note house is barely used from Nov to May, seasonal log cabin) Upstate NY, well water Filters: Sediment filter => GAC+KDF filter => CTO Carbon filter Professional plumber install - paid $800, well worth it, they have the tools, they have the skills, they have the patience, well, most of the time. To do it over again: would 100% get the Spin-down filter to lessen load on sediment filter. May still do this but may not have room. Nick, if you're reading this and seeing the pics, what do you think? We research every major purchase, whole house filter was a major need. Built a log cabin on a small lake in the Adirondack park in upstate NY. Well drilled about 200'. Water is potable, tested several times, but there was some flakey silver particles and other sediment in the toilette and clogging up the screens. Water tasted just fine but needed to get rid of this sediment. We looked at several companies and settled with iSpring for the sheer quality of their product and the amazing customer support. I dealt with Nick in the beginning of the purchase process and he guided me to the right product and the right filter combinations. Nick is incredibly knowledgeable, patient and understand customer service and a good dude. Was going to give it go to install it myself as there are good videos out there but went the professional plumber route and glad I did. We included a bunch of shut-off valves with a bypass and plumber put in a faucet to relieve the pressure when you change the filters (great idea). I wish he had put a pressure valve before the filter system and afterwards to see if there's pressure drop. We had one small issue which was one of the cannisters was damaged in transport (threads). Called iSpring, luckily Nick picked up, and he sent me replacement right away. Installed with no leaks, no issues. You will notice what the sediment filter is picking up which is amazing that was going through the house and we were drinking it. Water is clear, no sediment in toilette bowl or the faucet screens and taste amazing - neighbors come here now to fill their water bottles. We changed the filters after 11 months (6 months of heavy use). Sediment filter was replaced (obviously after seeing the pics), KDF filter was fine, carbon filter replaced but looked okay too (see pics). We finished our basement over the winter and the unit is now enclosed. Note: not easy removing the housing to change the filters, you will need two of those wrenches for sure. They're heavy when full of water so have a bucket underneath. When re-installing, don't overtighten and make sure your gasket is good and apply a bit of silicone to it before spinning it back on. Make this purchase, you will be amazed and even more amazed by the excellent support you get - that's what really did it for us as iSpring stands out in this area. Thanks Nick and the entire team there.

The 3 stage system works great! But the customer service is even better. Let me explain... I purchased this system in April 2019. It is recommended to change the filters annually... BUT, if you cannot release the water pressure on the system, you will never be able to unscrew the large filter housings. My first system manifold design had "red" pressure relief buttons so you could remove the pressure and thus unscrew the massive blue filter casings. I had issues with the "red" buttons not releasing the pressure enough to remove the blue filter housings so I contacted iSpring and they sent me another manifold without any buttons at NO CHARGE! They suggested installing a regular water spigot on the incoming and outflowing line to release the pressure so that it would be possible to unscrew the filter casings. As you can see in the pictures, the system works great. In the last few days, I changed out my filters again for the 6th time and for some reason, the middle manifold filter receiver developed two pinhole leaks. Once again I contacted iSpring and spoke to John. I explained the problem and he immediately sent my yet another manifold to replace the second one... NO CHARGE! I know of no other company on planet earth that stands behind their products like iSpring. I highly recommend this system if you are serious about having clean and healthy water to drink. This system is well made, robust in design, will last for years, and you will not believe how well this system filters your water. This system has the sediment filter and two charcoal filters. The area where I reside likes to brag about our water quality. DON'T BELIEVE IT. The sediment filter catches so much sediment that when I change the filters, the water in that filter is literally muddy. I am not embellishing, the water is muddy. If I wasn't filtering that stuff, I would be drinking it and would have no clue that I was ingesting dirt into my water. Hats off to iSpring and John for having such outstanding products and customer service. Tom in Collierville, TN

I have to say this was a very good purchase. It is very easy to assemble. The filters are great quality and very well packaged. Each filter is packaged in its own box and marked very well so you can make sure you place them in the correct order. The company also gives you a bar code to reorder your filters. I do recommend you run your system through the pipes for at least 10 minutes or more to clean out the system, its a dark blue color that comes out of the filter system at start up. Our water does seem so much cleaner. We have a water tester and it has reduced the chlorine factor dreamatically. I highly recommend this system.

Good product & filters Philadelphia water adequately. My wife says that her hair now feels better after washing. I also noticed that there is less hair loss while showering. Updated Friday July 6, 2018 (1 Month of use) Updated Tuesday July 10,2018 (added comments about hair) Installation: 1. Since I was installing this in the basement against a stone wall, I made a frame with 2 x 4 inch lumber which I anchored to the stone wall. 2. I learned that using a 1" copper bushing from the plumbing supply house is not a good idea, for the connection will leak. I then switched to a 1 in. x 3/4 in. Schedule 40 PVC Reducer Bushing which is deeper than the copper bushing with Teflon tape and the leak was sealed. 3. The Philadelphia water supply is >= 80 PSI where we live. The iSpring Documentation states that 80PSI is fine, but the yellow tags on the big blue filter canisters warn against water pressure >= 75 PSI. You should test your water pressure prior to installation. If your water pressure is too high you should install a water pressure regulator valve before the filter. 4. It is good to create a bypass loop so you can maintain water pressure in the lines while changing the filters. 5. I found that using the (Expensive) Shark Bite connectors especially around the iSpring WSP-50 - Reusable Spin Down Sediment Water Filter - 50 Micron, 20 GPM, 1" MNPT + 3/4" FNPT https://www.amazon.com/gp/product/B072YVNRZN/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 helps with the removal of the filter housing for periodic cleaning. (See attached Photos) Product Defects: 1. One of the blue filter holders had damaged threads which most likely became damaged during shipment. This filter leaked and I bought Dow Corning 111 O-Ring Silicone Lubricant (5.3 oz. Tube) Dow Corning 111 O-Ring Silicone Lubricant (5.3 oz. Tube) https://www.amazon.com/gp/product/B00CTUJNU2/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 which is certified for use on food service equipment and water filter system O rings. Even if you do not have a filter container with damaged threads, I recommend using a FDA certified O ring grease to make and keep a secure fitting. I called the Amazon Help Number 888-280-4331 and they sent me a replacement unit. Filtered Water Quality: With the system operating less than a week, we are very pleased with the results. It is well worth the cost and takes at least a day to install. After using the iSpring for a month now both my wife and I noticed that our hair has stopped falling out when we take a shower. There must be something really nasty in the Philadelphia water system. What are we drinking? My wife also noticed that some brown hair is returning. I do not know if it is the water filter or the vitamin supplements. The water seems softer and makes cleaning the house easier. Update June 11, 2019 This morning I changed my water filters which consist of a sediment filter and 2 carbon filters. The sediment filter on the left, is white when new. Philadelphia claims to have the cleanest water in the country. Then, what is all of this brown junk? I'm glad I bought this water filter system

I purchased this for well water in December 2016 and now it's April 2026. The system has been very reliable, even though I have not (with the filter changes). Other than being a Pro: -The water was consistently excellent. -It was easy to install -The design with 3 cartridges gives me some flexibility in what filters I can select -I don't have to drain the system first -Everyone knows how to use these systems, so it is easy to have someone help me with filter changes. Con: -It's little difficult to open. The Blue cylinder is full of water and often drops several inches to the floor of the crawlspace, splashing everywhere. I try to 'catch' it and prevent any damage, but have failed. Despite these shocks, it has not cracked or leaked. -Sometimes it's hard to balance the O-ring on when screwing it back in.

I installed this 3-stage system in 2020. I was impressed by the quality and the ease of installation. The water quality immediately improved in taste, clarity/turbidity and scale build-up. We have been VERY pleased with the performance and cost effectiveness of this System & the iSpring replacement filters. Additionally, over the years, whenever I had a question, a call to Customer Support got me to a LIVE knowledgable person with real answers. Recently, after 5 years of use, one of the filter caps (black female threaded piece that accepts the blue filter housing) developed a crack. I called Customer Support first thing to check about a replacement repair part. Within seconds my call was answered by Nick and within 2 minutes Nick thoroughly understood my situation. He indicated, even though I was well beyond warranty, he would ship me a complete new top machine head (all 3 black caps assembled together in a new mounting bracket). All Nick needed was a copy of my original invoice and my shipping address. This Customer Support was the BEST I have ever received (and I’m a 77 year-old Handyman/Engineer). Entire call lasted less than 5 minutes and the whole mood was positive and focused on fixing my issue. Oh, additionally, the Machine Head arrived in less than 2-½ days (55 hrs.from my call!!)!! HIGHLY RECOMMEND!

Thanks Sean. Great product. Moved into a new house 6 months ago with a tankless hot water heater. Wanted to make sure that scale buildup wasn’t a factor in the longevity of my water heater and eliminate the need for bottled water around the house. Easy to install.
