Frequently asked questions
In Europe, any smart dehumidifiers bought new from an official reseller benefits from a legal conformity guarantee of at least two years (Directive (EU) 2019/771). This guarantee covers defects present at delivery, whenever they first manifest.
You can pick: European law puts the legal guarantee on the seller, not the manufacturer. In practice, a store return is usually faster, but the manufacturer can repair if the damage is out of warranty. Keep proof of purchase.
Our public methodology adds a Nura Score /10 penalty to any smart dehumidifiers whose recurring failures are documented in European user feedback. A model that breaks too often never tops our charts, brand notwithstanding.
Yes, within the limits of the European "right to repair": routine maintenance tasks (cleaning, gasket replacement, calibration) never void the legal warranty. Only irreversible hardware modifications can be a problem. For a smart dehumidifiers, any handling documented in the manufacturer's manual stays covered.
The directive imposes a two-year legal conformity guarantee, with a presumption of pre-existing defect during the first twelve months — the burden of proof is on the seller. For a smart dehumidifiers that breaks in that window, you're entitled to free repair or replacement, no strings attached on typical use.
