## Description

iSpring FD25B Deionized Water Filter for Spotless Car Wash System, Fits WGB22BD Deionized Water System for Car Wash, 4.5” x 20”

Review: Better window washing results than the professionals! - I should have bought this years ago. I used to hire professional window washers at $300-400 per visit. This iSpring unit made window washing a breeze and gave me a better outcome than the professionals...very effective. I was able to wash every window without squeegeeing at all. The result is a beautiful, spot-free window. Hands down the best value for the money, pays for itself in one use! It's compact in size and is easy to move around. Easy to operate and was leak-free! I like that the filter longevity will last me several years.
Review: Great Product, Great Customer Service! - The iSpring Spotless Car Wash System (Model WGB22BD-BP) is a must-have for any car enthusiast. It delivers truly spotless, streak-free results thanks to the deionized water—no more water spots, even in direct sunlight! The bypass valve is a great touch, letting you easily switch between filtered and regular water. I did have a a couple hiccups with a few missing parts, but iSpring’s customer service was fantastic. Nick responded quickly and had the replacements shipped out immediately. His help was above and beyond what I expected—super professional and efficient. Great product, even better support. Highly recommend!

### ⭐⭐⭐⭐⭐ Finally! Soft Water for a spot-free carwash
*by B***K on May 30, 2025*

Overall solid product. Generally detail cars using a 'rinseless' approach with distilled or DI water, and got tired of going to the local grocery for it. This system makes it way easier to source soft water, and is portable enough to be mobile. I am also able to use this in conjunction with my Ryoi pressure washer (1.8psi/1.2gpm) and do not experience any reduction in performance. Took me a few times using it to learn to drain the water/hose line AND 'de-pressurize' the containers before disconnecting things (water goes everywhere). I use quick connects on both sides for convenience. No leaks or drips.- everything connects and works as it should. During the install I ran into some challenges and called iSpring Water Customer Support. The support rep, Nick, was super helpful and took immediate action to help resolve (10/10 customer support, thanks Nick!!).
