iSpring FD25B Deionized Water Filter Replacement for WGB22BD, 4.5x20 in

Previously, after each car wash, I had to spend extra time wiping the windows and wheels to remove stubborn water stains and marks. With this Aishipulin water purification system, these steps are no longer necessary. The deionized water washes the glass until it's crystal clear, free of stains and mineral deposits; the wheels don't need scrubbing and remain sparkling clean. I also use it to clean the chrome exhaust pipes, leaving them shiny and free of any hazy residue. You can first use regular water to pre-wash the wheels, then switch to purified water for a final rinse. The mobile cart moves flexibly around the wheels, and the included hose is long enough to ensure every corner of the vehicle is thoroughly cleaned. This system has halved my car wash time, and the glass and metal parts on my car look brand new.

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.

Works as advertised. Good value compared to others on the market. Easy assembly. Reduced the TDS (total dissolved solids) in my super calcified well water from 400ppm to 1ppm. Spot free rinse on my black truck even in sunlight. Delivers about 3 GPM to my pressure washer, measured by me. Perfect rate. Any more than that doesn’t give the filters time to work.

I purchased the portable system with the bypass valve ( important) to be able to hand wash my new vehicles myself, as well as some of my 12 foot windows without spotting. I tested my house water before connecting the filter ( about 127 ppm), and was pleasantly surprised to see a zero ppm from the outlet. I have it hooked up to a pressure washer and highly recommend installing a digital flow meter and an adjustable valve inline to keep the flow at under 2 gpm through the media. I am very pleased with the results and have achieved spotless results on my vehicles. One last suggestion: I found that lifting the entire assembly on a work bench greatly aids the installation of the 2 media canisters onto their bases.

I use this product for work. When it works it works well. My home water is about 250 PPM and it gets it down to about 18 PPM. Good enough to not leave streaks or marks for the most part. Then it just stopped working on me and I have no idea why. It still came out of the machine at 250 roughly. I reached out of their support staff and after getting through to them Sean helped me out and sent replacement filters FOR FREE. He’s been very good at communicating with us and helping us out. Thank you Sean!!

Owning a black truck and having hard water can be a huge pain. So I figured I would try this to keep me from always having to hand dry. Well I tried it and it works. Rinsed the truck on a hot day and didnt dry it off. Dried spot free! My only tiny complaint is I was hoping for a 0 TDS but it will only get it to 2. My straight tap water is 105. But 2 is still spot free. I believe anything under 50 will be spotless. Considering what I pay to have it hand washed and dried, this thing will pay for itself in 3 washes.

I bought the deionized water system for car washes. It left water spots on my car and windows. I do not recommend this product.

I purchased the iSpring system and assembled it the day it arrived. I noticed a slight defect in one of the filter housings. The defect prevented the housing from forming a good seal when closed. I reached out to the manufacturer, sent an email with a copy of my invoice and a picture of the housing. They immediately shipped a replacement housing. The iSpring system has operated flawlessly. The customer support was fast, responsive, and met expectations. It is refreshing to deal with a company that values their customers. Thank you, Sean!

I think it’s a poor design.. there should be open and close valves on both ends of this product at this price.. product is going to be back washing into the second filter all the time.. also this stand is 17 inches WIDE not counting the handle! It’s a terribly lazy design.. the handle should also be removable, instead it’s WELDED ON?! Common give us a bit more ability to even consider one day installing it on a wall or something… I don’t have much room in my garage and this thing stands out and isn’t sleek at all.. Please offer an option to wall mount it??
