Features

01Reduces heavy metals and organic impurities

02Improves taste and reduces chlorine

03One bag filters up to 120 L of water

Aarke Boost Filter Granules are water filter granules designed exclusively for the Aarke Purifiers’ ReFilter System™. Ideal for hard water and for brewing coffee and tea, they make tap water softer and better tasting by reducing limescale, chlorine, heavy metals such as lead and copper, and other impurities, while adding magnesium and zinc.

Developed in collaboration with BWT, one of the world’s leading water technology companies, Boost Filter Granules combine ion exchange and activated carbon to reduce unwanted substances that can affect water quality, taste and odour. The added magnesium and zinc create mineralised water that helps bring out the natural flavours and aromas of coffee and tea, while reduced limescale helps protect kettles and coffee makers.

The granules are poured into the Aarke Purifier’s refillable stainless steel filter cartridge. Each pack contains 3 refill bags and is compatible with both the Aarke Purifier and Purifier Large. One refill bag filters up to 120 litres of water and should be replaced every 4 weeks, depending on water quality and usage.

Boost Filter Granules are also available with the Aarke Filter Subscription, making it easy to always have new filter granules ready when it’s time for a refill.

Dimensions: H 18 x W 4 x L 12 cm
Weight: 3 x 100g

Filter performance: Up to 120 L or up to 4 weeks
Filtration time: 3-5 minutes per litre

Filter granules change interval (per bag): 4 weeks

Developed in collaboration with BWT
Manufactured in: Austria

Ion exchange resin*, activated carbon, mineral magnesium and zinc.

*Ion exchange resin is made from polyacrylate, a type of plastic formed into small solid grains that attract and exchange ions, a standard, required part of any filter jug that reduces substances like limescale and heavy metals.
