iSpring WSP50ARJ+WGB32B+RO500AK Ultimate City Water Filtration Solution

I have been very happy with my 3 stage filter system and pre-filter spin down. Everything arrived in good shape and installed easily. No more chlorine taste for us. Francis was helpful answering the couple questions that arose.

The water tastes amazing and fills faster than my fridge dispenser. (although it's not "fast" by any means, it's more than sufficient.) Now that it's installed, I wish I would have installed it years ago. Nitrate levels are high in Iowa and this unit lowers them to near zero, along with removing other harmful contaminates.The part that held me back for so long was drilling a hole in my granite countertop. It ended up being not bad at all. Just buy a quality diamond drill bit made for stone/granite and watch a few videos on youtube. I bought the Milwaukee 1/2 inch diamond bit and it worked flawlessly. 1/2 inch is the right size for the faucet that comes with this unit.As far as other complaints or concerns from the reviews:I didn't have any leaks at all after installing. Take your time and make sure connections are tight.Install overall took about 2 hours including drilling the hole in the countertop. What took me so long was my own fault- I ended up having to remove my dishwasher and pull the power cord through the hole in the cabinet where the dishwasher had power. I didn't think about how the open power outlet with the garbage disposal only works when the switch is on.Noise: it makes a bit of noise while you're dispensing water, but it's not loud at all under the sink. I barely hear it.Size: the unit isn't small but doesn't take up that much space under the counter.Overall I highly recommend this unit. I've only had it a few days but so far it's been amazing.

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've had this filter for about two years and it has performed flawlessly. I used to get a lot of sediment from my well, but now it all gets stopped by the filter. I clean it manually a few times per year and have it set to auto-flush every 60 days.Installation was a breeze. I had a plumber replacing an old boiler at the same time, so I did the PEX-A setup with the spin-down, fine sediment and carbon filtersThe PROS: Very solidly built with sturdy brass top fitting where the water goes in and out. The acrylic bottom is easy to remove with the tool and goes back together easily. The filter is stainless and easy to wash off in the sink to get the particles that auto-flush misses.The customer service is the BEST! Recently I spoke with John about filter size since some of my drip emitters are clogging. Calls are answered promptly by a knowledgeable staff who offer advice, replacement or whatever you need. I had a very small leak in the bottom of the drain valve and I received the replacement within three days. It's impressive when a company spends the time and resources to help its customers after a sale since it is definitely not the norm.The CONS: The auto-flush timer is poorly documented (as of 11/2022) so I had to call customer service a few times. This is an add-on at the bottom of the filter canister where the flush valve is located.There is no control over when it flushes - it is initially set the the time you make the setting, so if you program it a 10 am that is its schedule, but over time it seems to trigger later and later till finally you have no idea when it will trigger a flush.This is a minor issue since it does work periodically even though you never know exactly when.TIPS:I pinched and damaged the sealing gasket one time when I put the unit back together. Since you are basically out of business when this happens, I suggest the company include an extra gasket with the kit. At the time, they were out of stock so I had to find a replacement online.Be sure to use silicone plumbers grease on the gasket so it will go on and off easily and don't overly tighten. I found twisting by hand till it is firmly in place with no leaks is enough.I highly recommend this product and company.

I have spent a ridiculous amount of time researching RO system over the past few years and finally pulled the trigger and bought this one. In short, I'm glad I did!We already have a whole house filter and our refrigerator also has a drinking water filter. Myself, I wasn't overly concerned about using that water, but with all the talk about all the chemicals and crap that's in our water, my wife decided so would no longer even drink that water and turned to drink bottled spring water, which has nano plastics in it and produces all that plastic waste from all those bottles. So, in light of all that, I decided that now was the time to get an RO system.Having experience with the typical RO systems that have the tank and all the tubing running everywhere, I knew I wanted a tankless system. They're also so much more efficient and produce much more water and take up far less space. I spent several more weeks going back through all the options and finally narrowed it down to two systems; the Waterdrop G3, and this iSpring RO500AK-BN, with the iSpring being the clear winner for a number of reasons.First, the company is amazing and they are located near Atlanta, where we live. Whenever I've called to ask questions, they just pick of the phone and are so helpful and personable. Michelle answered all my questions and I felt confident I was getting a system that met our needs. I absolutely love iSpring and feel that I will always have top-notch support for this product, should I ever need it.Secondly, I love that this system has the remineralizer built in, so you don't need to add an additional filter inline. This makes filter changes so simple and reduces connection points. This was important to me, knowing that my wife could easily maintain the system herself if she ever needs to.Those were the main reasons that stood out before I got the system. Now that we have it installed and have been using it for a while, I find many more reasons why I'm happy we chose this one.It's super-easy to install and comes with everything needed, provided that you have an electrical outlet located where you plan to install this. You do not need to be a plumber to install this. If you don't have an existing outlet, you will need to install one (or have an electrician do it, if you're not able to.) Luckily, we already had power under the sink for the disposal, so I had no problems converting the hard-wired disposal to a half-hot outlet, which now controls the disposal via the existing switch and provides a hot outlet for the RO system.All the parts and materials are extremely high quality.The system is super-quiet when operating! Seriously, I can barely hear it if the room is completely quiet. I've read that others are quite noisy; not this one.It takes up almost no space in our cabinet! (Still have room for all the crap that was in that cabinet.)Operation is simple and intuitive. It has color-coded indicators that show filter status, as well as audible alerts when filters are nearing end of life and/or need changing.Changing filters is as easy as it gets and takes literally 10 seconds. The design of the filters is also so much better than on traditional RO systems, where I've often had the main O-rings go bad, leaks, etc. These should never have any of those problem because of they way they're designed.The included faucet is high quality and beautiful! It's listed as 'brushed nickel', but it blends perfectly with our stainless steel faucet, so I think it's more of the blend of brushed nickel and stainless. IDK, but it just looks very nice!The flow rate is amazing and even faster than our fridge water dispenser. It can also produce up to 500 gallons of water per day and the flow rate is continuous, unlike typical RO systems that slow down to a trickle when the tank runs out.It has a 2:1 pure to drain ratio, compared with 1:2 or 1:2.5 of a traditional RO system.And, most importantly, it produces the best tasting water I've ever had!All things considered, this is the best system I've seen in the $500-ish price range. You get a lot of bang for the buck with this one and exceptional quality and support. I actually like it better than some I've seen that are closers to $800-$900, which still don't have all the features of this one.Also, mine included a card to register for a 3-year extended warranty, which is really nice and added piece of mind. If you buy one, be sure to register it. I was getting an error when trying to register on their website, but I was told to just send an e-mail request and Sean responded the same day to advise that my warranty was registered. (Did I mention how helpful the iSpring folks are?)All things considered, I highly recommend this system and iSpring as a whole. I paid for this system and received no compensation for this review. In fact, I passed up on a couple of similar systems that were offered to me for free and instead decided this was what I wanted and purchased it myself.

January 2026 update:Customer support has been amazing. For any issue or question I have, Francis from customer service has gone above and beyond to provide solutions. I was an early adopter to iSpring's auto flushing sediment filter. They've made some improvements since I first bought mine. Great warranty and replacement part support. My well water is really putting it to the test and it is handling it!With the updated valve design, you will require an adaptor to hook up to a garden hose now. The male threads are not garden hose thread. Look for 3/4" MHT x 1/2" MIP adaptors. See attached pictures.-------Original Review:I've been using it for about 10 months and it's really been helping with the sediment from my well. However, I've needed to do a couple special things to get it to work for my situation:1) replace the small hose with a garden hose to get the spin down feature to really work, and set the auto flush to happen every day *2) switch out the 50 micron filter with a 100 micron The included hose is too restrictive. When you flush the filter, the water flow is too slow to clean the filter sufficiently. Attaching a garden hose increases the flush rate. Now the water rushes down the filter and you can see the spin down effect working well. I only need to set it to a 30 sec cycle with the garden hose. I have it set to do this every day in order to keep up on the finer iron sediment that collects on the filter walls. I will say there probably is an optimal hose diameter that is somewhere between the included hose and a garden hose to create the best spin down effect. I recently got a 100 micron filter from ispring (thanks Francis for sending it quickly and free of charge!). The 50 micron was just too fine. My goal is to pick up just the larger sediment before my iron and sulfur filter. The 50 micron would get gunked up with iron too quickly. Water pressure was fine right after flushing the filter, but over the course of a few days there would be a noticeable drop in pressure. The filter would be visibly caked in iron. I would usually flush the filter right before a shower to ensure good water pressure. I would try to remove it and clean it every few months once I got tired of the low pressure. My hope is that the 100 micron filter doesn't trap the iron as much, and only the big stuff. Flushing the filter with the garden hose attached gets all the big sediment out just fine.

Product: iSpring WGB32B 3 Stage whole house filter.Date installed: June, 2022First Filter change: May, 2023 (note house is barely used from Nov to May, seasonal log cabin)Upstate NY, well waterFilters: Sediment filter => GAC+KDF filter => CTO Carbon filterProfessional 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.

We live in a small town that has experienced frequent periods of discolored water for decades. We'd see it in our toilets, sinks, and bath tubs, knowing it is in our food as well. It would last a couple days and be gone. We purchased a 10' x 10' x 30" kiddie pool for the grandchildren, set it up, filled it, and the water color was disgusting. It was almost the color of tea. We drained the pool, washed it out, and purchased a small filter that attaches to the garden hose. Refilled the pool again and the water was again discolored, but not as bad. Drained the pool again and put it away until we could resolve the water issue. We didn't need a water softener, nor did we want the purchase and upkeep expense for those types of systems. We did research online and found that iSpring filter units kept popping up as one of the top three best rated whole house filters. They're competitively priced and installation looked straight forward. We found the unit that we believed best suited our needs and purchased the model WGB32B unit off Amazon. This unit came with three filters; 5 micron particulate and two carbon filters. It arrived in a few days, and after reading the instructions I decided to install it myself. Our house has CPVC water piping so that made things easier. A trip to the hardware store for $50 worth of pipe and fittings and we were ready to be "plumbers". I first mounted the manifold unit (minus the filter housings) securely to the wall next to the main water supply line. Don't skimp on secure mounting as this unit is fairly heavy (maybe 40 lbs dry), even with out being full of water. I laid out the piping and fittings in the configuration I'd draw up before starting, cut the piping after some measuring, and "dry fit" (not glued, only hand fastened) everything together. After some adjustments, I shut off the water main, drained the pressure, and as much water that would drain. I cut into the CPVC main line at a predetermined place, drained residual water, dried the piping off, and started installing the piping and fittings, gluing them together starting at the main water pipe and working my way around the filter piping system. Once together, I allowed the glue to cure for an hour. While waiting for the glue to cure, I installed the cartridge filters into the housings and installed them onto the manifold, snugging them with the included wrench. After an hour, time for the leak test. I had all faucets in the house open. I slowly cracked open the main water inlet valve and slowly closed each faucet in the house. I could hear water filling the cartridges as the air was being pushed out of the system. Once the air was purged, and all faucets closed, the system came up to full house pressure. No leaks! I closed the filter bypass valve and we opened the closest faucet to the iSpring system and allowed water to flow for 10 minutes as instructed in the directions to flush out any carbon particles (didn't notice any visual carbon particles). Checked for leaks again. All good! We ran water in each faucet to flush the house system for about 15 minutes. Checked for leaks AGAIN. All good. Still not leaks.A couple installation notes:1) For the threaded connections on either end of the manifold, I used 12 wraps of Teflon pipe tape AND a coat of good pipe sealant on top of the tape. The instructions said this could be a leak point, so I took no chances. I carefully tightened the adaptors into the ends of the manifold. I did not "bottom them out", but was a few ticks tighter than "snug". The manifold is a type of heavy plastic. I was using PVC fittings, but if you're using metal, be careful. Over tightening could crack the manifold.2) As stated above, use heavy hardware to fasten the unit to the wall. I used a 2" x 10" board screwed into the wall studs with nine #9 x 3" deck screws, then lag bolted the manifold to the the board. The heavier the better. Do not use wall anchors in drywall! Do not use small screws such as drywall screws! If you have to, build a mounting bracket.3) I installed a low point drain on my system. When it comes filter changing time, I wanted to be able to close the inlet and outlet filter valves, open the bypass valve, drain the pressure and and much water out of the manifold as possible. I can also use this as a low point drain for the house system if that's ever needed. I encourage you to do this as well.4) I did not install union fittings in my system. This would allow removal of piping without the need to cut the pipe. If I had anything that I'd change, that would be it. I trusted my threaded sealant and gluing, but any leaks and I'd been cutting CPVC pipe out to fix the leak(s).We've only had our iSpring system up and running for one day, but we could tell a difference immediately. The water in our white porcelain toilets is actually CLEAR. It'll be interesting to see how long the particulate filter lasts in the conditions we experience with our city water. I expect 6 months with our city w...

I recently purchased the iSpring RO500AK, and the water quality has been fantastic. Unfortunately, my unit experienced a minor malfunction, but the way iSpring handled it made all the difference.A huge shoutout to Nick in customer support, who was absolutely amazing! He walked me through the troubleshooting process quickly, politely, and ensured my machine will be replaced. Product issues can happen with any brand, but finding customer service this responsive and helpful is rare.I highly recommend the RO500AK and wouldn't hesitate to recommend buying from iSpring to anyone looking for a reliable water filtration system!

The customer service alone makes this product an absolute must buy. It works well, easy to install, yummy water, great filtration, no leaking. We use it so much we were getting an error (incessant beeping) and immediately Nick proceeded to send us a tank kit to solve this. Very exciting! Thank you Nick!

I had an RO system with a tank, but I kept having minor issues. My plummer friend Kevin recommended this product. He was particularly pleased that it removes alkaline.I just followed the directions for installation. It was easy to install with no leaks on the first try. Though, I had Kevin check out my work just to be sure. It is about the size of a slim desktop computer and fits nicely against the side wall of the sink cabinet.I really like that it is tankless, so filtered water is immediate and always available. This becomes important in winter since I use humidifiers that call for purified water.It was much more expensive than the previous system, but as in all things, you get what you pay for.

I bought and installed this for my home 8 years ago. It is a great system. We are on city water, and every year when we replace the filters, I am amazed at how much grime has been captured! For several years I had the sediment and carbon combo. Last year, I switched to the sediment+carbon+scale filter combo. When I had a canister crack four years ago, Nick in sales promptly expressed me a replacement canister at no charge. Since then, they have updated the system, so when another old canister failed last week, Nick couldn't guarantee the new canister would fit properly, so he expressed me a whole new filter system - again free of charge! The customer service is amazing and while it is an expensive system, consider it an investment - it's worth it!!!
