## Overview

The iSpring WSP-1000SL is a durable, reusable whole house spin-down sediment filter featuring a 1000 micron stainless steel mesh that captures large particles before they reach finer filters.

Ideal for residential use, it supports up to 20 GPM flow and operates efficiently within 40-100°F and 20-90 psi.

## Description

The ideal water filter system includes a sediment filter as the first stage to remove the larger particles of dirt or sediment before they can reach and clog your finer filters and appliances. The WSP-Series aims to fill this role by offering the stainless steel mesh in various micron sizes, allowing you to control what size particles are allowed to pass into your home or following filters. This helps prevent large particles of dirt from clogging any finer filters you may already have in place. The WSP also includes a powerful anti-scale and corrosion agent called siliphos. Siliphos is a water treatment compound, a glass-like Polyphosphate containing Sodium, Calcium Magnesium and Silicate, formulated specifically for the treatment of water problems. The 1-inch outlet MNPT fitting provides a maximum 20 GPM flow rate, and the WSP-Series also features 3/4 inch NPT threads on the inlet and outlet. Specifications: Mesh pore rating: 50, 100, 200, 500, 1000 microns Dry weight: 1 lb Dimensions: 3. 5" width x 9" height Suitable temperature range: 40 - 100 °F Suitable pressure range: 20 - 90 psi

Ordered the WSP-100SL and had no issues with installing the filter but for some reason I continued to have a leak at the gasket. Called customer service and "Nick" was a pleasure to speak with and immediately sent me a whole new filter . Very pleased with the help and feedback they provided. Would greatly recommend to anyone.

    What a valuable add on to a well water system!
  

*by M***D on Reviewed in the United States on 29 November 2022*

Installed this unit (Siliphos type) before a 32K water softener with 1 cubic ft of Fine Mesh.  Hardness going into softener was set at 21.  Was experiencing slight "iron" and "manganese" discoloring in shower and commode.  Nothing that couldn't be removed with slight brushing, but it was still there.  Installed the iSpring spindown with Siliphos approximately 2 weeks ago.  I am absolutely stunned at the results.  There is no sign of staining whatsoever and this is after softener generations.  In addition, the water feels a lot "softer" if there's such a term!  I'm using the 100-micron filter, but I think I can go to the 50 microns luckily, I don't have a lot of sand or turbidity in the well.  I was planning to add a double filter (Sediment & Carbon after the softener) but I have to tell you, I really don't know if I need it!  This is money well spent.  Customer service was top notch.
