WSP Series

This is a great filter! It is durable and super easy to clean, plus the bottom clean-out valve has also been handy for bleeding down the system when we need to work on other plumbing (an unexpected bonus). You do need to put some thought into your water conditions before selecting a filtration size though, or you can run into trouble as we did initially. I-Spring technical support helped us work through our issues (Thanks Sean!), but a picture of our filtration set-up and a brief description of the water situation are included below in case you want to learn from our mistakes (prior to making your own original ones :-). Our well water is high in iron, so we needed to install an iron filter [big black tank] to protect the plumbing and hot water heater. The very expensive iron filter required a minimum of 30 micron sediment filtration on water going in (or warranty void and {very expensive} filter life could go from 3+ years to a few months). Our well is screened in a fine sand, and tends to produce more than we would like. So we installed a high volume sediment filter [blue] with the disposable paper filters (5 – 30 microns) that have to be replaced periodically. Those paper filters, like everything now days, cost more than you would like. The better the water coming in, the longer they last, so we installed the I-spring spin-down filter [far right] to help stretch the life of those paper filters. We went with the 50 micron filter, thinking that would maximize the life on the disposable filters. Turns out that was a bad choice. Our well produced 10 gpm at the pump when it was installed last summer, but when we turned on the house system (all new construction) two months later, we were getting much less. We were afraid the well capacity had diminished due to the drought this summer, but testing with the pump and pressure tank showed it was making significantly more than what we were getting at the house. It turned out that the problem was that 50 micron spin-down filter. The amount of sand coming from our well was too much for that fine of filter, so the system lost a lot of water pressure forcing it though. After consulting with I-spring, we are now running a 200 micron mesh in the spin-down filter. It is still doing the job of removing most of the sand, but we are getting double the flow. Moral of the story, be sure to select the right size filter for your water conditions. If you aren’t sure, buy a couple of different sizes and test them out. We have mesh screens for 50, 100 and 200 microns now, and they all work in the same unit case.

At first I didn’t think these kind of pre filters were necessary but chat gpt recommended this when we re did our plumbing filter setup since we have nasty butt water. Have this as the first line of defense before 3 10x4.5 filters Easy to plumb, compatible with 1” or 3/4” pipe. Had male threads on outside for 1” and female threads on inside for 3/4. Doesn’t leak at all after 6 months of use. I like the frame it comes with, able to mount it sturdy on the wall. The stuff this thing catches is impressive and it makes me uneasy thinking about what kind of particulate matter was in our water lines and drinking and cooking water before we had a way to see it Glad it’s working and glad we can see the particulates that are in the water. Money well spent.

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.

Have a well and have been losing pressure with quite a bit of sediment (sand). Pump and pressure tank are in my basement, which the elevation change caused an estimated 5-7 psi loss. Pressure tank is now upstairs elevated above everything except shower head. Placed this 50 micron sediment filter after pressure tank and then a 5 micron charcoal whole house filter. When I first turned pump on, pressure was noticeably higher and pushed a good amount of sediment into the filter and through the existing lines. Took apart all my faucets and pushed out a good amount of sediment. This product is definitely quality built and easy to clean out. Does it reduce water pressure on a well system? Maybe. My pressure is not as high as my parents in town, but more than enough for any application for which I use (my parents kitchen sink fully open is like a pressure washer which splatters water in about a 5' radius if it hits the bottom of the sink).

Produit de bonne facture. Il a l'air très solide, et est livré avec un joint de rechange et un support. Le seul problème est les raccords utilisés qui sont coniques, et nécessites des adaptateurs pour être reliés à des raccords européens (NTP to BSP). J'ai contacté le SAV qui a été très réactif. ils m'ont envoyé un filtre de rechange en guise de dédommagement, car ils ne disposent pas dans leurs catalogues d'adaptateurs. Je remercie Francis du SAV qui a été très réactif.

Good product.

Dieser Filter hat eine hohe Qualität bzgl Robustheit und Reinigung. Kann das Produkt trotz hohen Preis weitermpfehlen. Qualität kostet eben...

Una belleza de filtro !!! Ahorras dinero en cambios de filtros ya que el que trae es labable !!recomendado

Works well. Filters mesh was to small for my bore as it is very silty and dirty water. Contacted support and replacement filter being sent with larger mesh. No issues or hassles in getting replacement filter. Would recommend product
