• Highlight: Pure Water Power virgin DI resin polishes incoming water to near-zero TDS, the final step that lets water-fed pole cleaning dry spot-free with no wiping.
• Best For: Window cleaners running DI-only or RO/DI systems who need fresh resin to reach pure-water purity for streak-free results.
• Expert Note: Virgin (not regenerated) resin from Pure Water Power (PWP) delivers maximum exchange capacity and longer service between changes; running DI after RO stretches resin much further.
