I just charging my filters for the first time and that was easy as well. Customer support was quick and professional. I recommend this company. Review: Choose right filter size for your water conditions - 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. ## Features - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B072YVNRZN | | Best Sellers Rank | #7,126 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #2 in Whole House Water Treatment Systems | | Brand Name | iSpring | | Customer Reviews | 4.6 4.6 out of 5 stars (3,523) | | External Testing Certification | No | | Global Trade Identification Number | 00662425088331 | | Included Components | Unit, Wrench, Manual | | Item Dimensions D x W x H | 3.5"D x 3.5"W x 9"H | | Item Type Name | iSpring WSP-50 -Reusable Whole House Spin Down Sediment Water Filter 50 Micron, 1" MNPT + 3/4" FNPT | | Item Weight | 1 Pounds | | Manufacturer | iSpring Water Systems | | Manufacturer Part Number | WSP-50 | | Material Type | Stainless Steel | | Model Number | 50 Micron | | Number of Items | 1 | | Product Benefits | Reduces Sediment | | Set Name | WSP-50 50 Micron | | UPC | 662425088331 | | Unit Count | 1.0 Count | ## Product Details - **External Testing Certification:** No - **Item Weight:** 1 Pounds - **Material:** Stainless Steel - **Product Benefits:** Reduces Sediment - **Product Dimensions:** 3.5"D x 3.5"W x 9"H ## Images ![iSpring WSP-50 Spin Down Sediment Water Filter, Whole House Reusable Flushable Prefilter for Well Water, 50-Micron, 1" MNPT + 3/4" FNPT, Lead-Free Brass - Image 1](https://m.media-amazon.com/images/I/719mMNWpBpL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Should i expect a water pressure (psi) reduction by using this? if so, what pressure % drop have you experienced?** A: I'm getting a HUGE pressure drop of over 40 PSI! With sprinklers running I'm measuring 85 PSI upstream and 45 immediately downstream of the filter. It drops to 25 PSI after filtering sediment for several days. Back flushing as designed partially restores pressure the first few times, but then the filter element requires removal and scrubbing. Mine is the 50 micron filter element. I am now shopping for a 500 micron (which will probably act like no filter at all on my super-fine sediment.) I have a high flow rate of about 10 GPM in a 3/4" PVC sprinkler pipe fed by canal water (non-culinary) - a very demanding situation likely to produce a high pressure drop. Still, this big drop is far too much to be acceptable. I would not recommend this filter unless you have a much slower flow rate. **Q: is the clear housing glass or plastic** A: High impact plastic, bpa free and weather proof. **Q: Is the brass lead free? Can you provide certification to prove it?** A: John Browning, the seller should be monitoring these questions as much, if not more so, than the general public. **Q: Is the plastic part bpa free? what kind of plastic is it?** A: Hi, The plastic portion of this unit is made from PCTG and it is BPA free.

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. ## Frequently Bought Together - iSpring WSP-50 Reusable Whole House Spin Down Sediment Water Filter, 50 Micron Flushable Prefilter Filtration, 1" MNPT + 3/4" FNPT, Lead-Free Brass - iSpring Whole House Water Filter System, Reduces Iron, Manganese, Chlorine, Sediment, Taste, and Odor, 3-Stage Iron Filter Whole House, Model: WGB32BM - iSpring UVF55FS Whole House UV Water Filter with Smart Flow Sensor Switch, 55W, 12 GPM --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/44293952-ispring-wsp-50-spin-down-sediment-water-filter-whole-house](https://www.desertcart.tw/products/44293952-ispring-wsp-50-spin-down-sediment-water-filter-whole-house) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-05-06*
