Features
- Spot free effect:The system core adopts mixes bed deionized resin, which can effectively remove mineral ions such as calcium and magnesium from water. The water treated by it has extremely high purity, leaving no water stains, scale or spots on the surface of the vehicle, truly achieving no towels drying, saving time and effort.
- Mixed bed deionization resin: currently the best seamless water filtration material, its anion and cation resins are fully mixed at the molecular level, synchronously displacing positive and negative ions in water, resulting in more thorough reactions and higher efficiency. It can produce ultrapure water. Compared with traditional layered resins, the mixed bed ensures that every drop of water is thoroughly purified, achieving spot free effect.
- Visualize filter bottles and monitor the mixed bed resin status: The transparent resin tank design allows you to intuitively monitor the color change of the mixed bed resin, the filter cartridge is blue before use and orange/dark brown after use.
- Resin filters effectively remove TDS from water: When water passes through the resin, it can effectively remove total dissolved solids (TDS) from the water. Each deionized resin filter can remove approximately 1800-2000 TDS before replacement.
- Say goodbye to hard water stains, compatible with all models: suitable for various vehicles such as cars, trucks, motorcycles, RV RVs, bicycles, etc., also suitable for external cleaning of household windows, glass doors, etc
- Portable Design for Car Washing Everywhere: The product design is lightweight and portable, without the need for complex installation. Equipped with adapter, it can easily connect to your home faucet or campsite water source. Whether it's your garage at home, camping site, or on a long trip, you can always get pure deionized water anytime, anywhere to clean your RV, motorcycle, car, and even yacht without leaving a trace.

I use to always get frustrated washing my car cause even after drying I still saw those annoying spots. With this deionized rinse unit, it’s like magic. Just spray and let it dry by itself, no towel, no nothing, and the car is spotless. Makes me feel like I finally doing it right. The setup was pretty simple, just connect it and go. The resin color change is actually handy cause I don’t have to guess when it’s time to replace. I used it on my SUV, my motorcycle, and even the windows at home, everything came out clean and clear. It’s not the cheapest thing but man it saves so much time and no more re-washing or wiping streaks. If you love your car shiny without breaking your back with towels, this system is totally worth it.

I've used the "Spot Free Rinses" at DIY car washes and I've been leaning more toward using those rather than washing at home because of the drying step. I've used this spot free filter for home a few times now and it is making maintenance washes so much easier. With a ceramic coated car, I almost only need to spray it with this and have a clean looking car. Not having to rush to dry in the sun is a huge quality of life improvement. This has been worth every penny.

Nice portable spotless rinse unit. Compact design and easy to setup. Filer media functions works and is worth the value you get out of it. Definitely use this as the last rinse to get a spot free wash.

works great - hard water in san diego makes it relatively annoying to clean cars from the tap. Mounted this inline next to he house and now have fresh filtered water leaving car spotless.

No more spot free rinse or hand drying! As a quick test I hooked this up to my pressure washer and everything worked great without leaking. It was easy to plumb up and connect the hoses. The filters worked great. I used less soap. I didn't even bother drying the car to see if it really could dry clean somehow and it really did!

I’ve been using this Deionized Spot-Free Car Rinse Unit for a few weeks now, and I’m honestly impressed. The setup was super simple — just connect it to the hose and it’s ready to go. The color-changing resin is a great feature because it lets you know exactly when it’s time to replace it, which takes the guesswork out of maintenance.

This was awesome for washing my car! The water is clean and does a much better job than water straight out of the faucet! Would definitely recommend this for anyone that lives on a well that needs to filter the water!
