The simple way to a spot-free rinse. No more hand drying or expensive 3rd party cleaning with the “on the go” mixed bed standard water deionizer. Dissolved solids are the culprit causing water spotting after rinsing your RV. The deionizer uses ion exchange technology that will remove all solids from the water source resulting in a mineral-free water that leaves no spotting after rinsing. We recommend not drinking DI water. Unit produces approx. 224 gallons of water good for 45 auto rinses or 7 Class A RV rinses with a TDS of 250 at 2 GPM (5 gallons per car/30 per RV) before recharging is necessary. Its unique features includes easy to carry handle on top, high grade virgin premium resin, and a travel friendly option of cap & plug for storage. Compact, lightweight unit is only 18 lbs. and measures 22”H x 6.75”dia. Unit is easy to transport and hook up. Works great in your driveway or on the road. Comes complete with a 4 ft hose, cap and plug for travel plus an easy-to-read handheld TDS meter. TDS meter lets you know when to recharge the deionizer.
