Style: Car Wash System
I didn’t purchase the system for washing vehicles but it did a great job in quickly rinsing off my truck and leaving it spotless. I purchased the APEC 300 for washing house windows. Living in an area with very hard water, containing many minerals, washing windows was a waste of time leaving leaving the windows spotted with water mineral stains. The APEC left them crystal clear with no water spots. It paid for itself with the first cleaning considering the going rate for cleaning windows is $300 in our area. This is my second spotless cleaner and the APEC filter system is much easier to handle with the filters encased in hard plastic shells. I was going to give it four stars for manufacturing deficiencies because the holes for the stand and handle didn’t quite line up with the frame holes but it was an easy fix with my DeWalt power drill and running a 1/4 inch drill bit through for alignment. Overall, very pleased with the product.

I bought this to help speed up and take some of the work out of washing our large motorhome that is dark in color. We’re on spring water here, and it had always left spots so I had to hand dry it as I was washing it in order to get to the drying before it spotted. I now ONLY wash and rinse and have zero water spots. Filter life is heavily influenced by haw many impurities your filtering out, our water isn’t that bad and this is coming up on 2 years now for us and I’ve still now replaced the filters. That being said I’m not washing the motorhome every month either. Just washed the motorhome and superduty Ford yesterday and still no spots on either.

Style: Replacement Filter
Ok so I bought 2 of these and put them in the big blue and have a small 10 in pre filter in front of it on a cart and all that. We build them at work so I modified one of the old cart’s. Wish I had a picture. Anyways used it last weekend and omg this thing worked great. Even washed the car with it and purposely let the car air dry and not one spot but then did the other car and got a few spots even though I dried this one off. But the spots weren’t too hard to get off. Wiped them off with a damp microfiber towel. Then I put it away and used it again this weekend got more spots. They’re not really too bad or hard to get off but basically it only works great for the first time and that’s it. lol. For the price of each filter not sure if I’d buy them again. Gonna try it again tomorrow and should be able to make my decision. well I used it again. spotted up really bad and I even dried the truck off. spotted up before I could even dry it..its not my soap cause Im using good soap and rinsed it off thoroughly.the filters are plain and simply not working...got a couple of washes out of them and thats it..missed the return window by 2 days that sucks cause they,re like 70 bucks each..but will definitely never buy these again at all and will tell every one I know that is considering these to not purchase them, total junk. just talked to my friend that just purchased that 400 dollar one on amazon with the same 2 filters inside told me that his only worked for a couple of washes too just sitting in his garage collecting dust.not worth it at all to me. wish I would have talked to him before I bought these. once again . JUNK. WOULD NOT RECOMMEND... WASTE OF MONEY...

So far so good! I've done about 20 car washes using this water system, so it more than paid for itself. It was very easy to put together and for the most part, I've only had to lightly wipe down each vehicle after - to really get the windows clean. I did take the advice of other reviewers and purchase separate hoses. I also am very mindful of how much water I use each time I wash because as many have pointed out, the filters are about 60 bucks each to replace. What's funny is that I used to spend longer going to the car wash and sitting around waiting for my car to be washed. Using this product not only saves me time but helps me get much-needed exercise. I simply throw on a podcast, and before you know it I'm done. This is one of the best products I've ever purchased on Amazon!

I love this system! It’s helped me wash my car in hot weather where I don’t have to be in a hurry to dry it off and worry about water spots. UNTIL NOW! lol This system can be used with a power washer, but you will go through the filters fast. I got about 10-12 car washes out of it (3 vehicles) and the filters need to be replaced already. They show pictures with a power washer and that’s on me just assuming I’d be just fine with one. Then reading the information again I see it states “maximum pressure @ 90 PSI”. So in other words use a garden hose with a regular nozzle to spray. They usually don’t go above 80 PSI. So I will see with the next filters I buy using a regular spray nozzle how long I get out of them. It definitely works though! So much more laid back to not worry about drying off in a rush.

The APEC the de-ionized water system works OK, I think it would work better with more resin per filter. When the product showed up it was damaged and leaking while Amazon did reduce the cost but It was still a pain in the butt to disassemble find the correct parts to repair it and get it working correctly.

I own a large rv motor coach which is hard to dry going up and down on a ladder with a microfiber towel to dry. This item is great, saves a lot of time and no spots on the glass or paint whatever. Thanks.

Will update as we go: Our first one leaks right where the two filters connect so contacted Amazon for a replacement and just got our new replacement. So hopefully the new one doesn’t leak. As for water spots uncertain as we just used it for the first time, we have extremely hard water and it did help a little bit but I wonder if it’s because it was the first time. Will update as we go and use it more Update: has done a few washes with it now! Our first system was definitely flawed and our new one right out of the box didn’t need to be filtered through! Barely left water spots and we have very hard water also! So far liking it!
