ᐅ Odor zone in Kallax after installation – is this normal?

Hello everyone,

I recently assembled a Kallax shelving unit from IKEA and noticed that a so-called "odor halo" forms after assembly. Specifically, I mean that there is a fairly strong smell in the immediate vicinity of the freshly installed unit, which I believe might come from the processing of the materials. I am curious whether this is normal and if this odor could potentially be harmful to health, or if this odor halo simply dissipates after some time.

Has anyone had similar experiences or can explain this phenomenon from a technical perspective? I am particularly interested in whether the smell originates from the wood panels or from any adhesives or coatings, and if this affects the indoor air quality.

Thanks in advance for your insights!

Hello,
this term is very interesting, and I would like to ask in more detail: How do you define the "vapor circle" exactly? Are you referring to a visible haze around the shelf or solely to the smell?

The timeframe would also be helpful: How long does the odor last, and how strong is it? Do you or any other household members experience any physical reactions?

Without such precise information, an assessment is difficult.

Aside from that, volatile organic compounds (VOCs) often develop from particleboard or medium-density fiberboard (MDF), which are responsible for the "new smell." It would therefore be useful to know more about the material and the surface treatment.

Are there any further details about your Kallax model and the assembly?

Hi,
I think the term "haze circle" is quite fitting, it even sounds a bit mystical 😉

From my own experience with Kallax, especially with new furniture made of particleboard and laminate, there is this typical smell that can sometimes be quite strong. However, I have never noticed any lasting damage; usually, it fades away after a few days to weeks.

I imagine that in a well-ventilated room this is harmless, but if the smell is very intense or someone feels uncomfortable, it’s better to air out the room briefly and possibly avoid spending time there for the next few days.

So: Yes, I would say this is normal, even if unpleasant. By the way: usually, it really disappears over time. 🙂

This is exactly the point I want to explain in detail.

Chipboard, as commonly used in furniture like the Kallax, contains resins and adhesives that can release VOCs during curing. These substances include formaldehyde and other aldehydes, which are also responsible for the perceived smell. The intensity and duration of this odor depend on factors such as room temperature, humidity, ventilation, and, of course, the amount and type of adhesives used.

What many don’t realize is that some manufacturers already use low-emission materials or certify them with emission classes (e.g., E1). Furniture like this should be fairly safe straight from the factory, provided you selected the product correctly at IKEA.

If you have issues with the odor, airing out the room is the most effective solution. It can also be helpful to leave the furniture in a well-ventilated space for a while before placing it in a bedroom or living area.

I am curious: Was the Kallax stored somewhere before assembly, perhaps in a more humid environment? And did you fully load the shelf or leave it empty? This can also affect the off-gassing.

Edit: Additionally, the term “Dunstkreis” might also refer to a fine dust or mist layer — if that is relevant, please describe briefly.

Thanks for asking—these details are important to me as well.

The shelf was picked up directly from IKEA, so it was only in the car for a short time—relatively dry. I assembled it promptly, and the shelf remained completely empty the whole time, with no items inside.

The smell appeared immediately after assembly and initially seemed quite strong, but it noticeably diminished over the first two days. It is definitely a chemical odor, not dusty or moldy.

I have the Kallax in the living room, where I air out regularly, though the windows are not open daily at the moment due to the temperature.

I’m also wondering whether the smell might get stronger if the shelf is stored in an unheated room, or if the "fumes" are simply a direct result of freshly installed materials.

Does anyone have experience with how long this smell can last in the worst case, and when it can be considered no longer a health concern?

To answer the question objectively: From a scientific and health perspective, VOC emissions, especially from particleboard and similar certified quality furniture materials, usually decrease within a few weeks to levels that are no longer considered a health risk.

IKEA typically uses panels for Kallax that meet emission class E1, which comply with stricter limits for formaldehyde and other VOCs.

The perception of odor is subjective and depends on various environmental factors – particularly good ventilation effectively reduces the concentration in indoor air.

Specific recommendations:
- Ventilate rooms well and regularly, including at night if possible
- Avoid placing furniture in bedrooms without ventilation
- If the odor remains very strong for several weeks, further testing may be advisable (air measurement of wood VOC emissions).

In contrast to old, non-standard-compliant furniture, in my assessment the "odor zone" of IKEA Kallax is a short-lived phenomenon and not harmful, provided proper ventilation is maintained.
