Spotless Inline Water Filter. Colour Changing DI-Resin - New Improved Formula

Aquaspray® Spotless Inline DI Water Filter

Colour-Changing Resin – New Improved Formula

Whether you’re cleaning windows with a waterfed pole or carrying out a final rinse on a freshly detailed vehicle, the Aquaspray® Spotless Inline DI Filter delivers the pure, mineral-free water you need for flawless, spot-free results.

Designed for professional window cleaners and car detailers, this compact inline filter removes the dissolved minerals that cause spotting on glass, paintwork and windscreens — leaving nothing behind but a perfect finish.

💧 Perfect for Waterfed Pole Window Cleaning

When working with a waterfed pole system, water purity is everything. Even small amounts of dissolved solids can leave marks on glass once dry.

This inline DI filter:

• Removes minerals that cause spotting and streaking

• Produces purified water for spot-free drying

• Connects directly between your hose and pole system

• Gives you a visible indication of when resin needs changing

The result? Cleaner glass, fewer call-backs, and complete confidence on every job.

🚗 Ideal for Car Detailing & Spot-Free Rinsing

For detailers, the final rinse is critical. Hard water can leave unsightly mineral spots on paintwork, glass and chrome — especially in direct sunlight.

The Aquaspray® DI Filter provides:

• Ultra-pure, deionised water for final rinses

• Spot-free drying on bodywork and windscreens

• Reduced towel drying time

• A safer finish on ceramic coatings and waxed surfaces

Simply rinse and allow to air dry for a clean, professional result.

Intelligent Colour-Changing DI Resin

At the heart of the filter is our advanced mixed-bed DI resin, developed by Equip2clean and exclusive to the Aquaspray® range.

The resin changes colour from blue to yellow as it becomes exhausted. Housed in a clear cartridge, you can instantly see when it’s time to replace - no TDS meter guesswork, no wasted resin.

✔ Blue = Working
✔ Yellow = Replace
