  • Great system!
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. ... show more

  • Best tool I have for washing cars
Style: Car Wash System
I was skeptical that anything would work on our HARD water. Tested this out on an older vehicle first, before risking it on my new car. Seemed to work fine, so I used it to wash my new car, and it work beautifully. I didn't have to constantly re-rinse the car to keep it from drying. By the time I finished washing, half the car was completely dry, and not a single water spot. I'll probably have to change cartridges fairly often, due to how terrible our water is, but it's worth it! ... show more

  • Filters dont last very long!
Style: Car Wash System
Loved this thing for the first 60 days, it worked great, no need to dry or wipe down your vehicle or windows. That lasted for a few times of use, now its leaving spots on my windows and my truck! Filters are way too expensive to replace for the amount of times I used it. Amazon said I missed the return window by one week but I'm gonna try to return anyway. Really sad about the performance of this product, I've used Apec products for years and they usually perform great. Unless you don't mind spending 80 bucks every 3 months on filters I'd pass on this one! ... show more

  • Minor issue with fitting but APEC took care of it
Style: Car Wash System
Nice portable car wash filter system. It does what it is supposed to. TDS zero. I had a fitting tighten down too much when I tried to connect a water hose. Contacted APEC and they had a new cap to me by FedEx in a couple of days. No leakage. Works great.

  • Great system!
Style: Car Wash System
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. ... show more

  • It’s okay
Style: Car Wash System
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! ... show more

  • Spot free black cars
Style: Car Wash System
This has been a mircle for us. We have 3 blacks vehicles and very hard water. Since my husband has started using this, he has saved us hours by not having to dry the cars. We can actually wash and rinse and spots are down to a minimal. I highly recommed.

  • Leaving water spots after second use
Style: Car Wash System
Bought new filters for $140 bucks, washed my motorcycle, then about 6 weeks later I washed my 35 ft RV. Started leaving spots about half way through the wash. I tested a DI water sample was 110 ppm, tap water is 160 ppm. They say 50 PPM is max until you need to change the filters. Seems odd that the filters are ineffective so soon? Should I have drained the filters between washings? ... show more
