I installed this before the water pump so that it would also protect the pump. It draws the water up from the tank, through this device, and then into the pump, and then through iSpring's RV water filtration system - and then, finally, into our RV's various water outlets. It's well made and easy to install and was honestly trouble free and leak free. I had one of these installed in my house and I noted that even my tea kettle didn't end up with mineral deposits after I installed this unit. It's not a water softener, but it does help protect your appliances (think water heater, dishwasher, tea kettle, coffee machine, shower heads, etc.) while simultaneously filtering out larger debris that would have clogged said devices. No complaints here ... it's a nice, solid unit. Maybe the mounting hardware could be more solid ... I have to admit, that for an RV where you are bouncing and jouncing, you don't necessarily want your plumbing devices to be resting on top of a pair of arms. I used zip ties to fasten it to the arms, but that feels a bit bailing twine and chewing gum for my taste. It doesn't replace a nice solid mounting bracket - which is what I wish this came with. It's still a purchase that I would do again. Review: Quality Product that's easy to install and works well enough to pay for itself by extending the life of your cartridge filters! - This is a surprisingly "beefy" little unit - heavy duty glass container with heavy brass top and well constructed filter which is fairly easy to clean. Simple and straight-forward installation which was quite easy (they even provided some Teflon Tape!). Overall, I'm very impressed with this unit so far and will buy another for my camp house assuming I've encountered no problems after 3 months constant use (only been 40 days since I installed this). I installed this unit ahead of my cartridge filters and there is no doubt in my mind that it will significantly extend their life based on the amount of contaminants/sediment it has already prevented from reaching them - UGH!!!. I purchased the unit with the "Siliphos" filter because I have EXTREMELY hard water and the "Siliphos balls" inside the filter are supposed to help reduce hardness. I can't honestly say just yet how effective they are in reducing hardness and scale because I believe this might take some time to truly be effective. I'll update this aspect of my review after 90 days or so use. My only complaint with this unit is that I wish a mounting bracket were included or at least available for purchase to support it. There's no issue if you are installing it in rigid piping of any kind that is properly supported on either side of this unit BUT if that is not the case and one or both sides are connected to flex piping, the installation doesn't appear as neat and professional. I've not experienced any leaks so far, but it is a concern in the back of my mind over time as the piping is already sagging and I'm trying to determine the best way to support it (ie; can't strap pipe directly to the wall because you need room around the filter to be able to use the supplied wrench to remove the filter canister. I'll add some photos of my solution for this (assuming I find one). ## Features - Rated at 50 Micron.

How can I purchase one? **Q: does it descale** A: Yes and no. There are 2 versions of this product on Amazon. One includes Siliphos granules. Siliphos is a descaling agent. **Q: Can this be used as a post filter for an inline water heater?** A: Hi, Yes you can use the spin down filter as a post filter after an inline water heater but the spin down filter may be best used before the water heater to protect the water heater from sediment buildup. Thank you, iSpring Water Systems LLC **Q: Does it matter what direction this is hooked up?** A: Yes! If you look on the side of the filter housing at the top you will see an arrow pointing the direction of flow. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality water softener substitute that is easy to install and does what it is supposed to do *by P***S on May 30, 2026* I live full time in an RV and we find a variety of water quality, but I wanted something that wasn't a salt-based water softener to help protect my camper's water-based appliances.

I can see how dirty the town water is, and this filter can get rid of most of the sediment. I ordered a 50 micron one but my faucet didn't run smoothly. I emailed them, and Francis got back to me very quickly. He told me the 50 micron is possibly not compatible with the sediment volume and sizes in my water, thus 100 or 200 micron may resolve the issue. That is true, my water pressure is back to normal after I changed to a 100 micron mesh filter. Good product and awesome team. ## Frequently Bought Together - iSpring WSP-50SL Reusable Whole House Spin Down Sediment Water Filter Softener, Includes Siliphos Helps Prevent Scale and Corrosion, 1" MNPT + 3/4" FNPT, 50 Micron - iSpring WGB21B 2-Stage Whole House Water Filtration System, with 10" x 4.5" Sediment CTO(Chlorine, Taste, and Odor) Filter, 1" Inlet/Outlet --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/48450221-wsp-sl-series](https://www.desertcart.ro/products/48450221-wsp-sl-series) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-07-12*
