This solution protects your paint and delivers a brilliant, professional-grade finish at home
• Professional-Grade Certified Resin, Vacuum-Sealed for Maximum Potency： This system features 2 packs (5L each) of LANLANLANG brand mixed bed resin, independently developed and backed by NSF, REACH, SGS, and WQA certifications. Every bag is vacuum-sealed upon delivery, guaranteeing full filter media potency right out of the box for extended service life and optimal value.

This smarter distribution system purifies as it flows, delivering cleaner water and longer-lasting performance

• Real-Time Water Quality Monitoring with Included TDS Meter: Included TDS meter (batteries not included) lets you instantly check water purity and know exactly when to replace the resin. Pro tip: if the reading isn't zero, fill the system completely with water and let it stand for 5 minutes to allow full interaction with the resin. Reducing water pressure can also help – too much pressure may push water through before it fully contacts the resin
• Versatile Use for Auto, Home & Solar Panel Cleaning: Beyond cars, trucks, and RVs, this deionized system delivers streak-free results on household windows, glass, and solar panels. The complete kit comes with the filter tank, bypass valve, fittings, TDS pen, resin, and manual – ready to use out of the box.
