The Darlly PureStream+ inline hose water filter softens water and reduces scale by filtering out up to 40% of your tap water's calcium.

The Purestream+ is designed to reduce water hardness in your tub, which can help lower maintencnace costs in areas with hard water.

Hard water commonly causes scaling on your tubs walls, as well as white calcium deposits on jets, and buildup in your filter. Limescale can also build up inside the heater, which can casue damage and lead to calcium 'flakes' in the water. Limescale deposits are not only very damaging to the surface and to the internal workings of the spa, but can often be uncomfortable for users too.

The filter uses ion exchange resin to remove unwanted calcium and magnesium from the water as you fill up tou hot tub or swim spa. It can reduce calcium in the water by up to 40% for a 1000 litre hot tub, helping to extend the life of the pumps, filters and heater.

To use, simply fit onto the end of your garden hose using a standard hose connector and fill your hot tub or swim spa as normal.

0 - 500 Litres = 2 uses per filter
500 - 1200 Litres = 1 use per filter
1200+ Litres = Please contact us for guidance

Performance will depend on local water hardness and volume of water required to fill the hot tub.
