It is recommended to change the granules every 4 weeks or 120L.

There are many types of filtration technologies. Removing microplastics from drinking water requires a different type of technology than the one that has been developed for the Purifier. The Purifier features a filter technology with activated carbon - which reduces chlorine and bad taste and ion exchange resin - which reduces limescale and heavy metals, like lead and copper.

The activated carbon in both Pure and Enriched filter granules may help reduce substances such as:
- Pesticides
- Herbicides
- Iron
- PFAS (per- and polyfluoroalkyl substances)
- Hormones

However, the effectiveness in reducing these substances depends on the initial composition of your tap water. Because water quality varies by household and location, we cannot provide specific reduction percentages for these substances.

The Aarke Water Purifier is not designed to remove the following:
- Microplastics
- Medicines / Pharmaceutical residues
- Fluoride
- Nitrates
- Oestrogen
- Viruses

These substances require different filtration technologies that are not part of our current system. The Aarke Purifier is designed to improve key aspects of everyday tap water quality.

Please refer to this instructional video for detaching and reattaching the purifier's large handle, which enables the replacement of the glass carafe. A 2.5 mm Allen key is required for this procedure.

The Aarke Water Purifier, when used with either Pure or Enriched Filter Granules, has been third-party tested by a Water Quality Association-accredited laboratory and meets the following NSF standards:
- NSF 53: Reduction of lead and copper
- NSF 42: Reduction of chlorine

In addition, both the Aarke Water Purifier and Aarke Water Purifier Large are EN17093:2018 certified by TÜV SÜD, ensuring compliance with European safety and performance standards.
