Bore water and sediment pre-filter

1 · Fill your tanks

Granular activated carbon filters clog quickly and can't reduce dissolved minerals in bore water. Our Bore Water & Sediment Pre-Filter is built for tank filling - reducing calcium, iron and magnesium and protecting your tanks from sediment, rust and scale.

FAQ

Caravan filter questions

What's the difference between the pre-filter and the purifier?

The Bore Water & Sediment Pre-Filter treats water as you fill your tanks - reducing minerals, sediment and scale. The 5-in-1 Purifier treats the water you actually drink with Quantum Disinfection™ and ultrafiltration. The complete system includes both.

Do I need a plumber to install it?

No. The filters are lightweight, compact and connect in-line with standard fittings. Most caravanners fit them themselves.

How long do the cartridges last?

Each cartridge lasts approximately 3,500 litres, depending on water quality and use.

Can carbon filters handle bore water?

Granular activated carbon filters clog quickly on bore water and can't reduce dissolved minerals like calcium and iron. That's why we use a dedicated bore water and sediment pre-filter for tank filling.

Is the purifier suitable for homes too?

Yes - the 5-in-1 Purifier is suitable for RVs, caravans, boats and homes.
