Frequently asked questions

General FAQ

Do I really need Sküma water for my coffee?

All the water you drink contains minerals, including your tap water. Sküma purifies your water of all impurities and offers a perfect blend of minerals to maxmise your brewing consistency and optimise your extraction.

  • Chlorine reduction - prevents bad aftertaste
  • Total alkalinity reduction to 40 mg/L (or ppm) - helps stabilise pH and coffee flavours
  • Magnesium hardness increase to 56 mg/L (or ppm) - acts like a buffer stabilising pH and increases sharp fruity flavours
  • Calcium hardness reduction to 68 mg/L (or ppm) as CaCO3 - flavour balance and better extraction
  • pH closer to 7 - avoid acidic flavours
  • Sodium concentration below 10 mg/L (or ppm) - no salty flavours
  • Total Dissolved Solids (TDS) at 150 mg/L (or ppm) - maximise overall extraction
*calcium, total alkalinity and TDS levels will change according to your tap water

Are the minerals natural?

Our mineral mix is naturally sourced from the Great Salt Lake in Utah (U.S.A). The lake naturally contains high amounts of trace minerals like magnesium and potassium which makes it ideal to extract all the complexe flavours from our coffee bean.

What does Sküma filter?

Sküma uses a 3 stage Reverse Osomosis filtration system combined into a single compact cartridge. This filters out almost everything from the water including (but not limited to):

  • Virus & bacteria
  • Fluoride
  • Microplastics
  • Chlorine
  • Heavy metals
  • Lead
  • Arsenic
  • Organic compounds

How long do the minerals last for?

Each mineral concentrate refill contains 170mL which is enough to mineralise more than 250L. This should last you anywhere from 4 to 6 months depending on your consumption.

How big is Sküma?

The device is a compact, no-intsallation, countertop reverse osmosis unit. Just plug and play. Dimensions (25 x 30 x 40 cm | 9.8 x 11.8 x 15.7 inch)
