Harvia Water Filter Set

Steam generator spareparts | HWF

Water Filter System, Small

Harvia’s HWF is a water filter solution for steam generators and combi heaters in home or commercial use. Filtration systems are recommended for these products, as unfiltered hard water causes calcification in the water tank and on other components, shortening the lifetime of the steam generator or heater. The Harvia HWF system removes nearly all calcium, magnesium, and other minerals from the water, not only preventing hard water damage and surface stains – but also removing any odours caused by hard water. The Harvia HWF guarantees soft, filtered, and purified water.
