πŸͺŸ Why should I ventilate?

Regular ventilation is essential for a healthy indoor environment. Here’s why it matters:

  • 🧼 Cleans the air by removing COβ‚‚, odors, and moisture

  • 🦠 Prevents mold by reducing excess humidity

  • 🀧 Reduces germs and allergens, improving your overall well-being

  • 🏠 Protects your home β€” proper airflow keeps walls and furniture in better condition over time


❌ What not to do

Keeping a window constantly tilted open for long periods is not effective for air exchange and causes unnecessary heat loss.


βœ… What to do instead

Use intense, short bursts of ventilation by fully opening the window. This quickly replaces stale indoor air with fresh outdoor air.

⏱️ How long should you ventilate?

It depends on the outside temperature:

  • πŸ₯Ά 0Β°C and below: 2–3 minutes

  • 🧊 Around 5Β°C: 5 minutes

  • 🌀️ 10Β°C and above: 8 minutes

πŸ’‘ The colder it is outside, the quicker the air will exchange!


πŸ” How often should I ventilate?

  • πŸ›οΈ Bedrooms & common areas:
    At least twice a day β€” ideally in the morning and evening

  • πŸ› Bathrooms:
    Always ventilate after every shower to prevent humidity build-up and mold

  • 🍳 Kitchens:
    Open windows during or after cooking to reduce moisture and odors


♨️ Bonus Tip: Don’t forget the thermostat!

πŸ’‘ When you open the windows, set your thermostat to a minimum or temporary pause mode. This avoids wasting energy or confusing the system β€” otherwise, it might try to heat the outside air!
