Duyoku D. I. Rinse Pro 100

The media could not be loaded.  Bought this unit for our motorhome first day I washed a black truck and black car truly no water spots my TDS coming out of my house was 197 out of the unit was zero not sure how long the resin will last but very satisfied with this purchase—-OK I’ve had this unit now for 7 months I’m reading 1 on the meter I fave done 3 vehicles and 2 motorhomes many times not to count my neighbors cars I’m still very happy with this purchase

If you wash your own cars/boats/rv's this thing really works. You can spray off your car in the S. Florida summer heat and there will be no spots. We have very hard water here. 379 TDS on the meter before the canister, 0 after. It's not cheap but I believe it's a better value than the cartridges. I doubt I will get 4000g out of the resin but 3000g would still be good in my opinion based on the TDS starting point.

I have the D. I. Rinse Pro 100...they got it right ...4000 gal vs 400gal...no brainer...i did build a kart and added a pre-filter to preserve resen even longer...it works great ...two trucks full size...about 8to 10 months on resen..use and understand how to use the tanks by-pass to straight water for my results

Works as advertised. Leaves no spots. It is wonderful. No wiping dry needed.

Very satisfied, excellent results giving me no water spots on my vehicles, wish I had purchased something like this years ago.
