Description

Quality Construction, Built to Last Aquatic Life has 40 years combined with experience in retail sales, water filtration, marketing, product development and manufacturing. Product development is guided by comments and suggestions from retailers and consumers who use our products. We are a big enough company to meet our customer’s demands on time, but small enough to provide service that is unmatched in the industry. The reason you see unsightly water spots left behind after washing is from TDS (total dissolved solids) in water. If you’re looking for a quick, effective way to wash your car and avoid hard water stains, then you’ll love this inline spot free rinse system. That’s where this DI car rinse unit comes in handy. Even better, when you’re finished rinsing your car, truck, RV, or motorcycle, you can let it air dry! Our water system does all the heavy lifting for you. This water deionizer delivers a spot-free rinse without you having to towel dry. It’s as simple as that. When water passes through the resin, TDS (total dissolved solids) are removed. Each cartridge will remove approximately 1,800-2,000 TDS before you need to replace the resin. Included 0.75 Gallon Per Minute Water Flow Regulator ensures the resin has time to remove the TDS from the water for the perfect spot free rinse. TDS in water can vary greatly depending on the water quality in your area. To achieve a flawless, spot free shine, you need to filter out TDS from your water. You'll get many years of use from this DI car wash system. When the resin in cartridges are used up, they'll turn a tan color and can then be replenished with our bulk DI refill.

5 stars
Color: Black & White
Works great, as I was assembling the filters I noticed that there was a white plastic in either the inlet or outlet side of the filter I forget but I simply went with a needle nose pliers & took it out cause it looked like it was restricting the flow of the water. The 1st time I used it I put on the nozzle that came with the filters, 2nd time I used it I tried hooking it up to my 2000psi electric pressure washer to do the final rinse and it worked like a charm! I recommend this product 100% if you don’t like having to dry your vehicle off after every wash. I also would buy new water hoses when you install the filter ... show more

Works as advertised as long as you follow the instructions.
Color: Black & White
Works exactly as advertised. Couple of things to do to ensure it works as intended- 1) use as final rinse only - this does not have a high flow filter and not meant to be used for the whole car wash, only as final rinse. 2) make sure you put the filter in correctly in the canisters. It can go in backwards and if it does it won’t filter anything as water will just bypass the filter media. You can check with TDS meter (should read zero). 3) make sure you have the right nozzle to handle the low flow. Watch the videos they have on the best nozzles. Fan spray nozzles seem to work best. If you keep these tips in ind it should work well. My water was ~165 ppm (well water) and it reduced it to zero. Have used it to rinse my car about 5-6 times and the media has not shown any decreases in effectiveness and is still fully blue. Update: The filter media is still going strong after about 10+ rinses. One of the cartridges is starting to turn brown. ... show more

Great DI System For Some
Color: Black & White
This product does as it advertises. I’ve washed two vehicles with this so far and not a single hard water spot were on them. I’ve used about half of the first canister so far and the second one is starting to change colors as well. With that being said, my TDS meter is reading 512 ppm, extremely high. After using this system is sits right around 3-5 ppm. If you’re someone who washes their vehicle periodically and not weekly, this is perfect for you. The more frequent user should look at a larger system. I’m expecting to get about 8-10 vehicles done with the stock system before having to order more resin. Love the system, does as it should, just a little on the pricey side if you’re an avid car washer. ... show more

Don’t waste ur $
Color: Black & White
This is a scam product. You weren’t told that the water pressure delivers at half a pound. That right… .5 lbs of pressure. This isn’t enough water pressure to build enough pressure in a hose to squirt water more than a few feet. Water literally dribbles out of the hose. It’s not fit for washing anything other than something small and waist high. Lastly I washed a full-size SUV and resin Was completely spent. Meaning the resin had turned light brown. It took so long to complete the washing and the rinsing of the SUV he completely spent the filters. I have no idea how I’m supposed to give this a satisfactory review. It was a complete letdown and I would say that I got ripped off based on my expectations of how it’s marked it on the site. I did not return it because I used it. Bottom line buyer beware that this is a product that would probably be good for washing a single window, a child’s toys, or something small like a motorcycle. It is completely insufficient for standard duty and I can’t imagine trying to use it to wash a house is worth of windows. It just wouldn’t do the job ... show more

Small but the two filters work well on hard water. Use in conjunction with my car washing. Not for the house water sysrem.

Works great if used as described
Color: Black & White
With this, I would say there’s less than one percent of water spots left after my car washes done without it. Its water output is extremely low at probably no more than the garden mist setting on a typical hose however, for the price and its results spending the extra 10 to 15 minutes slowly going over the car with, its low water output is still better than anything else I have tried today ... show more

Runs out quick
Color: Black & White
Maybe it’s explained but it runs out quick. With new filters it does its job but my water is only 50tds to start and I bet I didn’t even make 100 gallons befor the water after filter read the same. And it comes out at a trickle

Works perfect! Exactly what I wanted to accomplish.
Color: Black & White
I've had a pressure washer hooked up in my garage for years. When I go to wash vehicles it's always ready, just hit the button and blast. And then when I got introduced to using a deionized rinse I saw life getting even easier by eliminating the most "work intensive" step...the drying! I wanted something just as simple but also effective, something I can get several uses from before having to recharge, not take up a lot of space and something that I could recharge using bulk resin because I hate the idea of buying throw away canisters and paying 4 or 5 times as much for the material which is already expensive. Also, I wanted it to be easy to see how my resin is holding up. This unit accomplishes all of that. I can recharge the existing canisters keeping costs down, one glance and I can see how resin is holding up and the whole thing mounts on the wall and takes up minimal space. And all that for under a hundred bucks (and about $25 in PVC)! So far I've washed my truck about 3 times and my car twice and used maybe 3/4" of resin. I don't know how my water rates for contaminates (I'm on town water) but I can say it looks like I'm going to at least get the entire season out of this before having to refill the canisters. And it does work just like they say, after washing and rinsing a vehicle I just give it one last rinse with the DI water and walk away. It actually dries more spotless than using a chammy which still can leave streaks. One cloudy day (about all we get here in upstate NY lately!) my truck sat in the garage and took over a day to finally dry, yet, not one single water spot! Update: It's been a year now and I can report, as I was hoping, the canisters did - albeit barely - last the entire season! My bag of resin came in last week, I'm about to refill them for this season. Looks like I'll get several refills (seasons) out of this $60 bag. For what I have invested this has been a most worthwhile acquisition, love the way this works! ... show more
