Small spots of rust occasionally appear on the steel parts.

Small spots of rust can occasionally appear on any metallic surface exposed to moisture, oxygen, or contact with other metals. While this can be surprising, please rest assured that these spots are completely harmless and can be removed easily by following the steps below.<div style="margin-left: 20px; text-align: justify;"> </div><hr style="margin-left: 20px; text-align: justify;">1. Wipe the Affected AreaUse a soft paper or cotton cloth to gently polish the surface where rust appears. Avoid using steel wool or any abrasive materials, as they may scratch the metal.<hr style="margin-left: 20px; text-align: justify;">2. Prepare a Citric Acid SolutionMix a 5% citric acid solution with warm water (around&#xA0;40&#xB0;C) for best results. If you don&#x2019;t have citric acid, lemon juice, or vinegar, an effective alternative.<hr style="margin-left: 20px; text-align: justify;">3. Submerge and SoakPlace the part with signs of rust into the solution and allow it to soak for 30 minutes.<hr style="margin-left: 20px; text-align: justify;">4. Agitate and InspectGently swirl or move the part so the solution reaches all surfaces. If any rust remains, use a soft cloth to loosen and remove the remaining spots.<hr style="margin-left: 20px; text-align: justify;">5. Rinse ThoroughlyRinse the part three times with clean, fresh water to remove any remaining acidity.<hr style="margin-left: 20px; text-align: justify;">6. Dry CompletelyAllow the part to air dry fully before using it again. Once cleaned, the Purifier part should look as good as new. However, if the issue persists, the part can be replaced, and the serial number of the purifier should be logged.&#xA0;

Claim reasons: Rust

The carafe is made from ~1.6 mm thick borosilicate glass. While not shatterproof, it is highly heat-resistant and withstands rapid temperature changes up to 165 &#xB0;C (300 &#xB0;F). If a carafe breaks during normal use, replacement carafes are available for purchase for both models. If the carafe arrives broken, it should be replaced free of charge.&#xA0;

Claim reasons: Broken carafe

Tips on how to remove and attach the handle.

Bad or Metallic TasteA slight change in taste can be expected, and variations are natural and often subjective. Perception of taste may differ from person to person and can also be influenced by the quality of the water used. It is recommended to follow the <a href="https://www.aarke.com/purifier-cleaning-guide">cleaning instructions</a> to see if this resolves the issue.In most cases, a thorough cleaning will alleviate the problem. LimescaleIf the desired limescale reduction is not achieved when using the granules, it is important to ensure that the Pure version has been selected, as the Enriched version does not remove limescale. If this is not the cause, the setup and cleaning instructions should be followed carefully.

Tips: Issues with the granules

Please refer to <a href="https://www.youtube.com/watch?v=OiWxTRyKUzA" target="_blank" rel="noopener noreferrer" class="fr-strong">this instructional video</a> for detaching and reattaching the purifier&apos;s large handle, which enables the replacement of the glass carafe. A 2.5 mm Allen key is required for this procedure.
