Good

Facil de usar e abastecer o tanque mas podia ser um pouco maior, como ele fica "OUT" antes de estar completamente vazio parece pequeno.

Appareil pratique, efficace et bon marché

Présentation pratique, prix très compétitif (production en Chine).
Je n'ai pas compris les explications du mode d'emploi, mais ai vite trouvé une façon simple d'utiliser l'appareil.
L'eau ne devient agréable qu'après avoir filtré une grosse dizaine de litres.
En extrapolant l'information affichée au bout de 2 mois, le filtre sera à changer après avoir produit environ 1 m3 depuis une eau courante déjà de bonne qualité (Montbéliard).
Le bruit est très faible... mais sauf à ajouter un tapis, l'appareil fait vibrer la cuisine et la rend très sonore. Un amortissement aurait évité cette gêne.

HANDIG TOESTEL

het is een handig toestel. Ik had wel een klein probleem na 2 weken het toestel in gebruik te hebben: de waterdruppel kleurde plots rood. Aan de filter kon het niet liggen want pas 2 weken gebruikt. Ik ben er uit geraakt door de vraag voor te leggen aan de AI modus van google. Nu werkt het toestel opnieuw prima

Does this countertop RO water system need to be drilled?

No ! You can use water filtration right away without needing to install it. Just plug it into a power outlet and it's ready to make clean water.

Is this water filter big? I have limited countertop space.

No, it's designed to be compact and small. It fits easily on your counter without taking up much room.

What is the alkaline mineralization function?

The mineralization function adds healthy minerals to your water, so you get beneficial elements like calcium, magnesium and more.

Does this purifier waste a lot of water?

No, it has a high 3:1 pure water ratio. It's efficient and wastes less water compared to other RO systems.

How often do I need to change the filters?

The filters last 12 months, so you won't need to change them often. This saves you money in the long run.
