ᐅ How can you ensure optimal airflow in Ikea Pax wardrobes?

Hello everyone,

I have a question that came up while using Ikea Pax wardrobes and I’m hoping for your experience or expertise: What is the best way to ensure optimal air circulation inside Pax wardrobes?

I have noticed that when the wardrobe is closed, it often develops a slightly musty smell, which is probably due to a lack of air movement. Especially when the wardrobe is full of clothes and other textiles, this can affect the freshness and longevity of the stored items.

I’m generally interested in how to improve air circulation without compromising the wardrobe’s functionality and appearance. Are there specific ventilation tips or modifications? Should certain shelves or ventilation slots be replaced or added? Or are simple measures like regularly opening the doors sufficient?

I look forward to your tips and ideas, preferably with brief explanations of why these solutions work.

Simply install ventilation slots on the back wall or doors. Alternatively, leave some space between the unit and the wall to allow air to circulate. Regularly opening doors is usually sufficient.

That is one approach, but without measurements or practical experience, it remains uncertain whether a few slots are sufficient. It is also important to consider that air circulation then heavily depends on external airflow.

Here I actually see a practical solution. If the cabinet is pressed directly against the wall, rear ventilation openings are hardly effective. Leaving a gap creates airflow, which increases effectiveness.

Another question is whether passive ventilation through small openings is enough, or if active ventilation (e.g., small fans) should be considered, especially if the cabinet is located in a poorly ventilated room.

Does anyone have practical experience with such active solutions?

For optimal air circulation in Pax wardrobes, I recommend the following points:

- Do not place the wardrobe directly against the wall; leave a gap of at least 3-5 cm (1-2 inches).
- If possible, modify the back panel: you can keep some of the pre-drilled holes or openings clear to allow airflow.
- Cover the ventilation holes in the back panel with fine metal mesh to keep dust out.
- Open the doors regularly for at least 10 minutes once a day, especially in high humidity conditions.
- If odors are strong, it is worthwhile to use natural air absorbers, such as activated charcoal bags or cedarwood.

I consider active ventilation unnecessary for most private households, as the risk of power outages and noise outweighs the benefit of improved air circulation. The key is combining small air openings with sufficient distance from the wall.

Wow, I find this topic really interesting! 🙂

I’ve had similar experiences and can especially recommend the following:

- Place cedarwood blocks or cedarwood chips inside the closet. They smell great and not only repel moths but also slightly improve air circulation.
- I cut small hidden vents into the doors that are not visible but allow fresh air in.
- And very important: my tip for everyone who loves fully packed closets – less is more! It’s better to have less clutter and ventilate regularly.

This can easily be integrated into daily life, especially in the morning while getting dressed. This keeps clothes fresh and prevents musty odors!

Slots in doors are effective, provided you pay attention to the overall air circulation in the room. If aesthetics are less of a priority, this can have the advantage of making the cabinet significantly less prone to moisture due to improved ventilation.

Combining this with breathable fabric storage boxes instead of plastic containers also helps to improve air circulation inside the cabinet.

While this does not promote air circulation, it has been proven to help against odors and moths. Nevertheless, air exchange remains the most important factor.

I wonder if anyone has documented the effectiveness of these measures using a hygrometer or similar devices?
