iSpring FWSP50ARB Spin Down Filter Replacement Cartridge, 50 Micron | Reusable Sediment Filter Cartridge with Scraper and Seal Cover for WSP ARB Series, 316L Stainless Steel Mesh

Living in a rural area, I rely on a private well for all of my household water. Even though my well is over 300 feet deep, it still produces a significant amount of sediment. I had already installed a multi-stage filtration system, but the sediment was clogging the filters so quickly that I was replacing them every month or even more often. Adding this spin-down filter ahead of the rest of my filtration system made a HUGE difference. It captures a large amount of the sediment before it reaches the other filters and automatically flushes the debris from the system. Since installing it, my replacement filters now last at least three months, which has saved me both time and money. Customer support was also OUTSTANDING. I had questions about extending the drain line and choosing between the 50- and 100-micron filter screens. Nick took the time to explain the differences and recommended the best option for my setup. He was knowledgeable, patient, and very helpful. iSpring has built an excellent product, and I highly recommend it.

I bought ispring’s WSP100ARB Spin Down Sediment Filter, WCF200K Whole House Filter, WCS45KG Whole House Filter, UVF55FS Whole House UV Filter. After installing the system, water quality improved significantly — hardness is gone, mineral content is much lower, and it’s clearly protecting our appliances. Lab tests before and after confirm the softener is working as expected. What really stood out was the customer service. Francis was fantastic. They were knowledgeable, patient, and went out of their way to help me over email. You can tell they genuinely care about making sure customers are taken care of. Highly recommend both the product and dealing with Francis!

Excellent for removing particles 50 microns and up. The auto flush feature (mine is set to trigger daily, for ninty (90) seconds) and built-in filter scrubber takes the hassle out of full filter maintenance, and reduces the intervals before requiring maintenance. The public water quality in my country (Trinidad and Tobago) is terrible. My previous first stage, five (5) micron sediment filter, requires replacement every three (3) to five (5) days. By adding a spin down sediment filter at the first stage, my five (5) micron sediment filter's lifespan has been extended to roughly two (2) weeks. Now this doesn't sound like much of an improvement, but at $30TTD per sediment filter, changed ever three (3) or so days, and consideration for the time spent monitoring and changing filters, this is a game changer for me. About two (2) weeks in, I needed some help understanding how the built-in filter scrubber mechanism worked. I reached out to support and John was more than willing to help. Six (6) months in, the seal for the reusable filter had stretched a bit from frequent maintenance intervals. John came to the rescue again by sending me a replacement cartridge. Thank you for the excellent after sales support John. I am completely satisfied. I hope iSpring builds a new iteration where the built-in filter scrubber operates automatically when the auto flush is engaged.

A Great pre-filter. I installed this when I moved into my new house with a Well system. The Well is rather old and while it is free of any bacteria or other nasties the water has a bunch of clay sediment in it. I have only basic plumbing knowledge soldered a pipe or two, fixed some leaks with shark bite connectors, and installed a sink or two and this was very easy if you plan out your install. There are many diagrams and recommendations online for diy, just make sure to install shut off valve before and after the filters as well as a bypass. I put this ahead of an I spring 3 (Sediment, Carbon, Heavy metal )stage 20 " sediment filter, followed by a UV light to kill anything left behind and I didn't want to have to replace these filters all the time (thus the pre-filter) I live on my own so my water usage is lower than most families, but with this filter for instance I average only need to replace my sediment filter every 1.5 years, rather than the usual 6 months. My carbon filter is also still is in almost new condition when I checked at nearly 2 years. Unfortunately, I don't have a Gallon count, so I am unsure of the exact usage. The only thing I would probably do differently if I had to set this up all over would likely be to is to order the 100 micron filter rather than the 50. I have pretty sediment filled water, so the filter can clog up very fast with the smaller size. I should let the rest of my filters do more work as intended as currently the pre filter can clog up faster than the automatic flush can clean it at times (flushes daily for 15 seconds). This can temporarily drop my water pressure significantly until I manually flush it, or clean the filter myself. Also, if your water is high in clay type sediment, it doesn't always flush out properly from the filter, so you end up having to manually clean out the filter on a monthly basis to keep your water pressure up. The built-in scraper is mostly useless as well unless you have large chunks of sediment as there is too large of a gap between it and the filter.

I'm editing this review to reflect the outstanding customer service from iSpring, specifically from Robert who helped me get a replacement module. I understand sometimes things happen, and although I think there can be improvements made to the module to prevent water ingress, I can find no fault with the company and their willingness to stand behind their products. We have a well and deal with sediment in our water. This was a lifesaver! I was replacing string filters every couple of weeks so I finally decided to give this a try. Instantly saw an improvement in the rest of my water system. The auto flush feature lived up to all the hype. Until today. The screen was black. Our water enters the house in an unfinished room of the basement so it's just the original stacked stone walls and dirt floor. The humidity can run high in the summer so I'm not sure if that is what killed it but somehow water got into the housing of the circuit board. I repair a lot of electronics and actually deal with water ingress in very sensitive equipment in my line of work so I disassembled the unit to dry everything out and clean any corrosion. No luck. The DC adapter still gives a good 4.9v, with that and fresh batteries the beeper sounds and E0 is displayed on the LED screen. I replaced the push button, cleaned all the pads that I could see had any trace of water....nope. I don't even know how the water got in. There was no sign of water in the battery compartment on top nor on the top of the circuit board. All the water was at the bottom. Not sure if the valve motor is still good because I can't get the thing to power on correctly. Now my spin down filter is a dumb filter with no easy way of flushing it. Its frustrating to have to replace the module only after 3 months but the company stood behind the product and Robert from their customer service department sent me a new module almost immediately after I sent in my receipt. And for what it's worth, it's super simple to remove and re-install. Overall, decent product, great company.

I just wanted to post a review of my Amazon purchase of 2 iSpring filters. I found the products to be very effective and well made and highly recommended. In particular, tech support is very important as I had some questions on the sediment spin down water filter I purchased. I dealt with "Sean" at iSpring and found him to be very responsive and knowledgable and a pleasure to deal with. It's important to have good tech support and help when installing these filters and Sean certainly rose to the occasion. Solid recommended company!

Customer service is very good. Dealt with Nick for a replacement unit and he was knowledgable and fast. Things to know about unit. 1. It is very effective in removing contaminants and sediment 50microns and above. 2. It must be cleaned constantly where I am in North Palm Beach, Florida. 3. I set it at 5 days 30 seconds flush and remove housing and spray filter once per month. 4. Automatic valve turning device has a plastic female receiving part that mates to a brass turning key. Plastic is weak and if you let inside of filter unit get dirty plastic female part may fail when turning valve off. 5. Small o-ring goes on bottom between white plastic fitting a brass fitting on bottom of housing. This is not mentioned in documentation??? Also, while there is a spare large o-ring kit does not come with a spare small o-ring or any other seals. 6. Use small amount of silicone lube to lubricate the o-rings. This is not mentioned in the documentation??? 7. Most importantly! “DO NOT OVER TIGHTEN PLASTIC MAIN HOUSING TO BRASS TOP CAP!” HOUSING WILL DEFORM AND NOT SEAL!!! THIS IS NOT MENTIONED IN THE DOCUMENTATION??? Otherwise this is a good unit and does what it is supposed to do. I trust the warranty documentation I mailed for the new unit guarantees it for another year since instructions are lacking information. Special thanks to Nick!!!

This is a very well‑made, dependable product, and the customer service truly sets the company apart. Installation was simple, and the unit has been working flawlessly from the start. Initially, I had the backwash draining into a plastic bucket, but I wanted to connect it to an existing elevated drain pipe a few feet away. I wasn’t sure if that setup might affect the filter, so I called customer service. Nick took the time to listen carefully to my concern and walked me through the solution. He sent the correct size drain line in the exact quantity I needed and recommended adding a check valve for proper flow. Everything worked out perfectly. It’s rare to find a company that stands behind its product with this level of support. Great product, great company, great service. Highly recommended.

Great product and great customer service. I was having quite a bit of clogging and I spoke with JOHN and customer support. They sent me a spare filter and also gave me instructions how to maintain and service them on a regular basis. I changed the rinse time to about 90 seconds and it really improves the filters ability to manage the course sediment. It’s a great product.

After years of replacing disposable filter cartridges every week and sometimes more often, we finally decided to try one of these spin down flushable filters. We were very impressed with the quality of the iSpring filter... straightforward installation and operation, and it works extremely well. A little too well in our case... we should have gone with the larger micron cartridge as it plugged up several times daily because of all the debris in our water supply. But we contacted customer service (US based, big thumbs up) and Julius was fantastic... they sent out the 100 micron replacement, even shipped free of charge to Canada. The larger micron cartridge works so much better for us. With the automatic flush set to once per day we have no more plugging. However, if you have a lot of debris or sediment I recommend going with the larger WSP-ARJ model which come with up to a 200 or even 500 micron cartridge. Spring and fall are worse times with our artesian well and we may need to do that yet. I wish we would have contacted iSpring beforehand and explained what we required, as I'm sure they would have advised us what was best. I must say there are not too many companies that impress me these days but this is definitely one of them. We may be expanding our water filtration system in the future and will not hesitate to buy from iSpring again, and of course highly recommend them to anyone looking for a quality product and service to back it up.

The catchment area for our private water supply filters through extensive peat hillsides and results in high amounts of particulates and quite strong tannin colouration. The high particulate levels mean that we have to change our 30 micron and 5 micron disposable every month or so. This is rather costly. So we decided to try adding a 50 micron iSpring spin down filter to "protect" the next stage filters from getting clogged too quickly. We bought the iSpring WSP50ARB Spin Down Sediment Water Filter in Nov 22 and it has now been operational for a few weeks. Pros: Excellent quality, great innovation, superb customer service (Canada to Scotland). Very easy to install (although NPT threaded connections aren't quite as common in the UK). The digital control unit is very straightforward to set-up, and the automatic spin down operation easily cleans the sediment that is collected by the filter. It is a bit too soon to judge how well it protects the next stage of filtering. But, nonetheless, I would wholeheartedly recommend it! Cons: absolutely none. Please note: the iSpring WSP50ARB Spin Down Sediment Water Filter is not designed to remove tannin colouration from water supplies. I have to employ an additional filtration stage to need this requirement.

Adquirí el iSpring WSP50ARB confiando en la reputación de la marca como una solución robusta y de largo plazo para el control de sedimentos en mi red hidráulica. Durante los primeros 12 meses, debo reconocer que la electrónica del temporizador de purga automática y la solidez del cabezal de bronce trabajaron de manera impecable. Sin embargo, justo al superar la barrera del primer año, el corazón operativo del sistema —la malla interna de acero inoxidable de 50 micrones— se rompió estructuralmente. Quiero ser sumamente enfático en un punto: el equipo operó estrictamente bajo los parámetros del manual del fabricante. Respeté rigurosamente los ciclos de autolavado programados, los límites de presión de trabajo de la línea y las rutinas de mantenimiento preventivo. No existieron picos de presión ni un uso excesivo; simplemente, la integridad del material de la malla cedió ante la fatiga en un lapso inaceptablemente corto para un equipo de este nivel de precio. Cuando una pieza tan elemental colapsa de forma tan prematura bajo condiciones de uso perfectas, mi confianza en la ingeniería de materiales de este modelo en específico ha quedado comprometida. A estas alturas, la idea de recibir un simple cartucho o malla de repuesto no resuelve mi preocupación de fondo, ya que nada me garantiza que el componente no volverá a desintegrarse al cumplirse el siguiente ciclo anual, dejando pasar sedimentos a toda mi tubería sin que yo lo note. Es sumamente decepcionante experimentar una falla de fatiga de material tan predecible en una marca de este prestigio. Ante un fallo de durabilidad tan estructural, el único desenlace que realmente restauraría mi respeto por el respaldo de iSpring no es un reemplazo temporal de la pieza, sino una solución financiera definitiva sobre la inversión realizada en este equipo, lo cual me permitiría buscar una alternativa más estable para mi instalación. Hasta no ver un respaldo de ese nivel por parte de su servicio al cliente, me resulta imposible recomendar el modelo WSP50ARB para quienes buscan una filtración confiable y verdaderamente a largo plazo.

Does the job but if you have sand in your water it will get clogged and you will have to manually clean it, the plug is not 3 pin UK its 2 pin US
