0 ppm, works as expected

Robert—January 2, 2026✓ Verified purchase

First time building a spotless system, these filters worked great, got to 0 ppm within the first minute of running water through them. Just wish SWS sold the centering rings on Amazon too. Read more

Buy if you want to waste your money.

angelica tornero—September 3, 2025✓ Verified purchase

Had it for just over a month I plugged it in and the resin started coming out. Of the the cartridges broke and customer service is no help all the money I spent for the dic-20 is a waste. Not buying again and they lost a customer. Read more

Spotless System works great for My RV!

Tim Sires—March 20, 2023✓ Verified purchase

The system works great for rinsing my RV! We have a large RV and with this system i don't have to worry about water spots on the finish. We live in the country and have well water for our water supply. Mineral spots have always been a problem for washing cars and our RV. The system leaves no spots and makes it so much easier to clean and it's a walk away after we rinse our vehicles. Read more

Don’t turn water pressure on too much

HD—November 24, 2025✓ Verified purchase

I have ordered four of these this past year. They seem to last for about six to seven good washes. I have learned that a gallon per minute flow meter, kept at 2.5 gallons per minute along with an RV in line water filter helps a lot and makes it work much better Read more
