DI Filter Tank
The refillable filter tank at the heart of your spot free setup. Built from robust FRP (fibreglass reinforced plastic), it connects directly to your garden hose via brass click-on fittings — no tools, no plumbing required. Resin is sold separately, so you only pay for what you need. The built-in bypass valve lets you wash with normal water, then flip to pure DI water for the final rinse. No disconnecting hoses, no water spots, no drying required. Refill the resin yourself at home when TDS rises above 8–10 ppm.
- Resin not included — buy the bundle to get everything in one order
- Bypass valve — normal water to wash, DI water for the final rinse
- Refill resin at home when TDS rises above 8–10 ppm
Best for: Cars, motorcycles, caravans, boats, window cleaning, solar panels

Tank + Resin Bundle
The easiest way to get started with spot free rinsing — everything included, nothing else to buy. The bundle includes the PureRinse DI Filter Tank, 12L of premium mixed bed resin, and two brass click-on garden hose fittings. Connect to your garden hose, flush the resin briefly, and you're producing zero-TDS water straight away. Use normal water for the wash, then flip the bypass valve to pure DI water for the final rinse. No water spots. No drying. Just a clean, spot free finish every time.
- Complete setup — tank, 12L resin and hose fittings included
- 12L of mixed bed resin included (up to ~7,500L output capacity)
- Most popular choice for detailers and caravan owners
Best for: Anyone starting out who wants everything in one purchase

Mixed Bed Resin (12L)
The only ongoing cost of your spot free system. When your TDS meter reads above 8–10 ppm and spots start returning, a fresh fill of mixed bed resin restores zero-TDS performance in minutes. Service life depends on your local water hardness — soft water areas (under 60 ppm) get significantly more litres per fill than hard water areas (above 140 ppm). If you're on bore water or in a hard water area, use normal water for the wash and save the DI rinse for the final pass to stretch your resin further.
- Compatible with all PureRinse filter tanks
- Lasts longer in soft water areas — shorter in hard water or bore water
- Store sealed, cool and away from sunlight to maximise shelf life
Best for: Refilling your DI Filter Tank — the only ongoing cost of the system
