For as long as I’ve been into coffee, I’ve struggled to recreate the amazing filter coffees I’ve enjoyed in cafes around the world. My struggles are officially over. I can’t overstate how dramatic a difference Peak Water has made.

Living in a hard water area I really noticed a dramatic difference in my brews after using Peak Water. It was great to have the ability to adjust the filter setting using the bypass feature.

Designed with sustainability in mind

Peak Water Filters are designed to be fully recyclable. The resin inside each Filter is infinitely regenerable and can be washed and completely recharged, ready for future use.
The resin loses no performance in this process and actually gets more efficient as it’s re-used. This cleaning and regeneration procedure is a professional service that requires expert processing.

The recycling process

Returned Filters are disassembled in Harlow Essex, England. The plastic cases are recycled for use in other products, the biodegradable carbon is separated and the resin is washed and regenerated.
The recharged resin is then used to fill brand new Peak Water Filters, that are then shipped out into the world.

How It Works

[H1]
Variable Tap Water

Water hardness has a dramatic effect on the flavour of coffee. This effect is difficult to predict, as tap water varies greatly from city to city. Your favourite cafe knows this and uses complex filtration systems to control and customise their water.
It’s why the coffee always tastes great.

[H1]
Adjustable Filter

Peak Water is the world's first adjustable water filter jug, allowing you to create café-quality water at home — anywhere in the world. *
The unique design utilises a gravity-fed bypass with variable settings, allowing you to decide how many of the minerals in your water are filtered out or retained.
* Peak Water is most effective in moderate to hard water areas.

[H1]
Dual-Ion Resin + Activated Carbon

[H1]
Dual-Ion Resin+ Activated Carbon

The Peak Water filter utilises a two-chamber design. The main chamber makes use of premium dual-ion resins that have the capacity to completely remove the minerals from your water. However, you want a small amount of hardness to get the best out of a coffee.
The secondary bypass chamber contains carbon only, which combats any unwanted organic compounds, but allows a desired amount of positive minerals like calcium and magnesium to pass through and re-join the newly softened water from the main chamber.
