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.

Ispring spin down filter
Style: Classic
Size: 50 Microns
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.

Good filter and Great Customer Service!
Style: Classic
Size: 50 Microns
I don’t write too many reviews, but felt like I had to for this product. I have a well water system and needed a spin-down filter to replace an old one that was no longer working properly. I purchased this product in 2023 and also purchased a spare filter so that I could replace the filter instantly and take my time cleaning the used filter, swapping them out each time. It has worked very well. The frequency of changing these filters out has been shortening over time as my well is aging (28 years old), going from monthly, to weekly, and lately twice a week. The one issue I’ve had is the o-ring on one of the filters itself is thin and wore out over time and broke. I couldn’t find the size o-ring I needed on Amazon, so I emailed iSpring customer service. Matt contacted me back and I relayed the issue with pictures. iSpring didn’t have an o-ring replacement available, so Matt sent me a replacement filter at no cost. I am so pleased with iSpring’s customer service that I plan to purchase their much larger sediment filter in the near future. I’m just waiting for it to go on sale or to a lower price. If you have sediment issues that one looks amazing with automatic flushing! The product name is: iSpring WSP50ARJ-BP Jumbo Whole House Water Filter System, 50 Micron. Thanks Matt and iSpring for your wonderful customer service!

An Excellent, Economical Particle Filter to Enhance the Lifespan of Downstream Filter Systems
Style: Classic
Size: 50 Microns
This review is for the iSpring WSP-50 particle filter that is used on city water. The iSpring 50-micron filter serves as frontline protection for my 3M Whole Home Sysem with scale protection. The two have been online for 6 months (since mid-August). After 6 months use, I believe that am in a good position to judge the attributes of the iSpring filter. First, the iSpring is very forgiving for those who forget to open the value to clean it out. I went nearly 4.5 months without rinsing out the system. I show a picture of the iSpring just before I cleaned it for the first time. Yuk! During the initial 4.5 months, I experienced no loss of water pressure, which I find amazing. Again, I am on city water, so most large particulates are likelly removed. Your results would undoubtedly vary, especially if you are on well water. But clearly, the iSpring WSP-50 did its job. Our main water problem is preventing corrosion and scale build up. We ran a water softener for decades that worked well. Unfortunately, its consumables (salt) were costing us nearly $300 per year, and that is not counting water that is wasted during the softening process. The softener finally quit working last summer, and it was time for different solition. Hence, I got the iSpring WSP-50 and 3M whole home system. I bring this up as iSpring has another spindown filter for comparable cost:, the iSpring WSP-50SL Reusable Whole House Spin Down Sediment Water Filter Softener. The WSP-50SL Includes Siliphos, which supposedly helps soften water and lessens scale and corrosion build up. If I was aware of the iSpring WSP-50SL, I would have installed it instead of the iSpring WSP-50. Unfortunately, swapping the iSpring WSP-50SL for the iSpring WSP-50 is not a seamless change, and I would require a plumber to install the WSP-50SL. In conclusion, the iSpring WSP-50 is an excellent pre-filter to protect a downstream whole home system. If scale build up from hard water is a problem in your home, the iSpring WSP-50SL might be your best bet for a similar cost. I believe that you cannot go wrong with either choice.

Well made filter. Great for and kitchen and one room. It definitely should have been made longer so you wouldn't have to flush it every other day.

This is an excellent prefilter and easy to install. No noticeable drop in water pressure. I comes with the FWSP-50 filter which is easy to clean. I ordered another filter to minimize down-time when cleaning it. CAUTION: the non-iSpring filter does not fit. I called Nick at iSpring today and he helped to identify the correct part and gave me ideas about cleaning it. He was very helpful and friendly.

Choose right filter size for your water conditions
Style: Classic
Size: 50 Microns
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.

Purchased for an unusual application
Style: Classic
Size: 50 Microns
I purchased one of these to remove sediment and biological material from sea water before it reaches the onboard watermaker on my sailboat. I am currently in a location with an incredible amount of suspended particulate matter and it was clogging my regular filters very quickly. Prior to purchase, I contacted iSpring customer support to inquire about the intended use, use in sea water and to get a recommendation on the proper screen size. I received an almost immediate response from Brian at iSpring. They said sea water was not a problem and suggested I start with a 50 micron filter for maximum protection and that if it clogged too quickly they would replace the 50 micron screen with a 100 micron. I was sold!! I ordered it up and installed. The unit itself is extremely well engineered and I was very impressed with the quality. Now for the real test. I was concerned that since the sea water feed is not pressurized, I might not get enough water to the watermaker. After about 3 hours of runtime, I took a look at the filter. I was shocked by how much gunk was in the filter. I started to question why I was drinking the water produced by the watermaker. After a few more days of running it was apparent the filter was getting clogged before I could finish a typical 6 hour run. The 50 micron screen was just a little too fine. It would be fine in more typical conditions but in this location it's just too fine. I wish I had the space to put 3 of these in a row with progressively finer screens. Customer support asked me to follow up with them and let them know how things worked out. I contacted them again and told them the filter worked great but that the 50 micron screen was just too fine. They wrote me right back and said they would ship me a replacement 100 micron screen at no charge! This device gets a 5-star rating from me and iSpring customer service gets 10-stars! It's not often these days to find a company that truly stands behind its products. iSpring is one of the few!! I can wholeheartedly recommend this device to anyone. You will not be disappointed. And if for any reason you are, iSpring will go out of their way to make it right! Well done iSpring! And thanks for the great support Brian!

Just what was needed

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.
