Description
Do I still need a water softener if my water is hard? Yes. Our WGB32B-MKS whole house water filter does not reduce hardness. It is recommended to install a water softener, such as the iSpring WCS45KG model, before this system if your TDS level is above 300 ppm. 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 remove the screws on the machine head and flip it. F3WGB32BMKS FP25B FG25B-KS FM25B LS43WL Leak Detector AFLT3 Water Filter Timer

Best Whole Home Water Filter On The Market!!
Style: Iron Manganese
Pattern Name: Premium
Let me just start out by saying I pride myself in being a DIY homeowner. My fiancée and I moved down to Southwest Florida in 2022 and have been struggling with our well water until I found this water filtration system. The water companies down here are gouging people anywhere between $5k and $10k for clean drinking water systems. I needed a solution to our incredibly intense sulfur smell and heavy sand/sediment buildup since we are so close to the water table down here. As you can see from my photos our water softener is designed to be outside since it never gets below freezing down here. Before I installed this whole home water filtration system by iSpring, I called and talked with them about any potential issues I may run into having their system installed outdoors. I was the year round Florida heat would be fine, but the intense solar energy from the sun could compromise the blue filter housing potentially allowing plastic to leach into our water supply. I went ahead and installed the whole filter with all the plumbing in a plastic resin container from Home Depot. I also preemptively installed a few bypass water valves behind the water filtration container in line with the house supply line incase of any future maintenance needed to be done, we could still draw water from our softener directly. I installed my system in June of 2024 and this iSpring system solved ALL of my problems! The sulfur smell was totally gone and we stopped seeing sand/sediment in our bathtub whenever we wanted to draw up a bath. I would also like to note, their system has had 0 leaks and is water tight. October 2024 Update: It has been 4 months and we are now starting to get that sulfur smell back into our water coming in the house. After calling iSpring and speaking with Michele, she informed me to get in touch with our local cooperative extension office to get a water test and bacteria test performed on our well water. Michele also graciously reassured me that our 50-micron spin down sediment filter wasn’t enough for our well system and that we needed a 100-micron filter. Michele has been incredibly informative as well as helpful in helping us get our water issues resolved. My overall takeaway with iSpring is I would give them a 10/10 and I highly recommend iSpring to anyone looking to get filtered water for their home! Customer service has been above excellent, the price for their products are very reasonable, the overall design of their system is minimal/not over complicated, and the ease of installation was a breeze!

What took us so long to get this?
Style: Iron Manganese
Pattern Name: Premium
Very Happy with this so far. My plumber installed in a few hours. Plumber said its easy to install. Perfect for our house size with 3 bathrooms. We live in a MUD district. No more water odor. Our water is clear. We can drink from the faucet and it tastes fine. Our skin feels better and cleaner. The value is exceptional. We purchased the premium. **Be sure and run your faucets/tubs until the loose charcoal particles stop. Its expected, dont panic.

Works well, some installation issues.
Style: Iron Manganese
Pattern Name: Premium
The filter works very well. But the inlet and outlet fittings are prone to leaking unless you wrap them with TONS of tape. The seem to not be tapered very much like normal pipe fittings. But if you buy your own 1 inch to 3/4 inch reducers (that are actually tapered) and wrap them with like 15 wraps of tape, then they won't leak. The filter bracket is not as sturdy as I would like. Not like it's going to break, but it flexes a lot. Ended up needing to shim it so the filters would hang level once they were full of water. All in all, given the price, compared to the similar commercially available filters I've found it's a good deal. Plus the housing is a standard size and seems to be good quality, so you have many options if you wish to buy your filters elsewhere, or different types of filters all together. All in all would recommend, but not a seamless install.

High quality, sound engineering, and exceptional customer service.
Style: Iron Manganese
Pattern Name: Premium
Have this system for a week now, so still in the early stages of ownership. Even so, I’m extremely pleased with this system. Considering that it is a whole-house filter, it has minimal footprint. It’s silent, efficient, and effective. I also installed the I-Spring Spin Down filter to help remove sediment and to help extend the life of the primary sediment filter. I’ve already noticed the absence of sediment deposits on toilets. It’s worth mentioning that I had some difficulty registering my systems on line (I think the problem was on my phone software) so I called I-spring for help. Robert at I-Spring took the reins and fixed it for me. After fixing the issue and registering both products he got back in touch to confirm success. I appreciate his professionalism and persistence. Thanks Robert.

Easy to install. No more smell. No more dirty water. Customer support from Nick is 5-star. Was very happy to solve my problems without a $5K system with salt from the big name systems.

Great support and great product!
Style: Iron Manganese
Pattern Name: Premium
Let me start off by saying I very rarely leave product reviews. I spent a lot of time researching water systems for my home. I ultimately came across iSpring products. I reached out to them back in November and provided a water analysis report I had conducted on my well water. They suggested the WGB32B-MKS based on the findings of that report. I ultimately selected this product and paired it with their pre-sediment spin down filter (WSP50). During install, I messed up and forget which filter was which (stage 2, stage 3). The stage 2 and 3 filters are identical in shape and color. There are no markings on the filter displaying what they filter, or a model number (That is one suggestion I do have.) I called iSpring's customer support and they quickly gave me a solution. The stage 3 filter weighs more. I was able to quickly identify the filter and fixed my issue. I cannot remember who I spoke with but they were VERY helpful. I installed the product in February, 2026. Within 3 weeks, I started having water pressure issues in my home. A faucet would slow to a trickle when I flushed a toilet or opened another faucet. I called iSpring again and spoke to Nick. He quickly was able to identify the issue. My spin down filter was completely clogged. I investigated stage 1 (sediment) filter and noticed this same level of debris in the filter. This is a not a iSpring product issue but a well water source issue. My water supply has a lot of clay/mud/iron, debris essentially. Nick spent over 45 minutes on the phone with me to help me come up with a plan of action. Currently the WSP50 spin down pre filter is a 50 micron system. The sediment filter on WGB32B-MKS is 5 micron. Based on his recommendation, I am installing a iSpring HB28B which is another single 20x4.5 housing. I am pairing it with an additional sediment filter. This time I am going 20 micron (iSpring FP25BX2) Nick quickly dispatched a new set of filters for my WGB32B-MKS 3 stage system which I highly appreciated. This support alone makes me HIGHLY recommend iSpring for your water filtration system. Finding good customer support (iSpring is U.S based) is extremely difficult today.

Must Have!!!

I wish I bought this sooner. The iSpring whole house water filtration system definitely improved the water taste and quality shortly after installation. Prior to purchasing I could taste the chlorine in the water and my entire family hated it, but now we enjoy our drinking water. The installation was very easy and straight forward. The manual listed all of the additional fittings needed so I was able to purchase the parts and install relatively quick and there was no drop in water pressure. I did have a small leak initially but after a quick phone call, Nick was able to help me troubleshoot and the problem was solved. I would definitely recommend to anyone considering a filtration system.
