ᐅ Kallax units and high humidity – how to protect them?

Hello everyone, I recently bought a Kallax shelf from Ikea to better organize my apartment. However, I have a problem with the humidity in my apartment, which often rises above 70% in spring and summer. I am wondering what the best way is to protect my Kallax from the resulting moisture. I am especially interested in whether there are specific treatment methods for the wood or practical measures I can take to preserve both the material and the stability in the long term. I would appreciate any tips!

The Kallax is made of particleboard with a melamine coating, which is quite resistant to moisture. However, you should avoid allowing water to come into direct contact with the surface. A tip: do not store damp items directly in the compartments and ventilate regularly to prevent mold growth.

I believe that simply recommending regular ventilation falls short in this case. A constant humidity level of 70% is not only a strain on the furniture but also affects indoor air quality. The question is whether a dehumidifier or at least a hygrometer would be useful to better monitor the conditions. What’s the benefit of protecting the Kallax if the humidity remains problematic?

From my own experience, I can say that a combination of humidity control and treatment of the wood surfaces is the best approach. Perhaps even a water-repellent finish for the visible surfaces?

For protective treatment: I would avoid using a water-repellent sealant since the melamine surface of the Kallax is already quite durable. It is more important to place the furniture properly – never directly against damp walls or in corners without air circulation.

Regarding moisture, I recommend regular airing (shock ventilation) and, if necessary, small dehumidifiers as a natural supplement.

I would avoid that because painting the Kallax can quickly make it look unattractive or cause damage, especially if the surface remains glossy.

When humidity is high, the only solution is to ventilate frequently and avoid placing damp items on the shelf. Otherwise, the wood will mold quickly.

Oh, I know that! I had my Kallax in a similar apartment and had great experiences with small silica gel packets that I placed inside the compartments! These moisture absorbers really help keep the furniture dry!

Also: A dehumidifier, if the budget allows, can work wonders! 🙂 I think it’s great to properly protect furniture, as you want the quality to last a long time!
