- Rated at 50 micron. Whole House Spin Down Sediment Water Filter. Ideal frontier water filter in whole house water filter system, protecting your entire plumbing system from sediment, rust, dirt, sand, and large particles. NOTE: Screens with 50 or 100 microns may be clogged very soon for water with high sediment content. Contact us for screen replacement in different size.
- Flushable and Reusable. Take the considerable workload off finer filters that follow behind it; unlike traditional sediment filters, regular flushing keeps the WSP performance in control. WSP series can be used for waste water treatment by spin down the sediment.
- Durable Whole House Spin Down Sediment Water Filtration. Solid lead-free brass machine head with stainless steel mesh filter screen that usually lasts 1 - 2 years.
- Easy installation with double threads.1-inch MNPT and 3/4 inch FNPT on both ends, garden hose barb fitting on flush out valve. See-through housing provides easy visual monitoring.
- Indoor friendly. Its for 40- 100F, 15 -115 psi and for indoor use only. Pressure loss or clogged frequently may cause by large particles. If the contaminants in your water are too many or too large, we recommend you choose a larger micron of filter or larger spin down sediment water filtrations like our WSP50B series and WSP50J series.

Using this on a rainwater collection system between the tanks and the RV 12v pump. Works wonderful, no issues and is nice and easy to clean when sediments build up. The valve is nice but it is also real easy to unscrew the shroud and clean the stainless screen itself.

I replaced a whole house filter with this unit. the filter is stainless steel and can be flush cleaned with built in pitcock. it has worked well. It works on loose particles . Not sure it would work on cloudy water so be aware if thats what your issue is.

I recently installed the iSpring WSP-50 spin-down sediment filter as part of my whole-house water treatment system, and it has performed exactly as I had hoped. In my setup, the WSP-50 is installed between a whole-house carbon filter and my water softener. Its primary purpose is to capture any carbon fines that may be released from the carbon media tank before they can enter and potentially damage or foul the water softener. The filter is well-built, easy to service, and provides a simple visual inspection of what is being captured. I particularly appreciate the flush valve feature, which makes routine maintenance quick and convenient without having to disassemble the unit. I also want to recognize Nick at iSpring customer support. He was extremely helpful in verifying the correct replacement screen element for my specific filter model. He responded promptly, answered my questions clearly, and made sure I ordered the proper part with confidence. Excellent customer service like that is becoming increasingly rare and is greatly appreciated. Overall, the iSpring WSP-50 has been a valuable addition to my water treatment system, providing an extra layer of protection for my water softener while giving me peace of mind that any carbon fines or larger sediment particles are being intercepted before they can cause problems downstream. Highly recommended.

This is a must have if you are on well water, or a municipal system with any sediment issues! My install is with a iSpring WGB32B-PB 3-Stage Whole House Water Filtration System. As a prefilter, it allows easy drain of the installation when changing the main filters, avoiding water most water spill and limited draining. Install with a shut off valve ahead and behind it if stand alone or before and after complete filter system and you minimize draining and nearly all of the need to bleed air from your water lines. The WSP is the best money I spent on our new house! It is available with 50 to ,000 micron level. If you are on well system, get at least a 100 or 200 as I did. The 50 will likelky create to much back pressure and cause the overload as I had when starting with a 50. If you are using a two or three stage whole house filter (or some under counter filtering and refrig water filter), the WSP will pay for itself in reduce filter replacements, not to mention, the easy draining of the primary filters to change the filters. I my install (with 3/4 hp well pump, using the 200 eliminated reduced the backpressure issue and provide still provided extended sediment filter life. If you have a 1/2 hp pump, you might be able to use the 100, but skip the 50 and pay the few extra bucks for the larger screen. Lastly DO put in the shut off valves to make it easy to drain and clean the filter. If a whole house system, spend the extra $10 bucks or so to provide the by-pass water shut off and you will have a much lower maintainence time when changing the filters and flushing out the air from the house water lines! Thanks iSpring!

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.

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.

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.

I installed this in front of my I-Spring three-filter system as a “pre-filter” to catch sediment and therefore extend the life of the primary sediment filter. Works like a champ. Robert at I-Spring was kind enough to assist me with product warranty registration when I encountered difficulties getting the system to accept my inputs. He took the problem off my hands, made it work, and the contacted me to let me know we were good to go. Many thanks Robert.
