How Many Dehumidifiers Are Needed in a Home?
Humidity is one of the most insidious enemies of any home. It can damage furniture , create mold, and negatively affect your health. A good dehumidifier can do wonders, but the big question is: How many dehumidifiers do you need in your home?
In this article we will help you find the answer, depending on the size and layout of your home, as well as the needs of each area of it.
✅ Why Do We Need Dehumidifiers at Home?
Before we answer the "how many", let's first look at the "why". Dehumidifiers:
- They regulate humidity levels, maintaining a healthy environment.
- They protect furniture , clothes and walls from mold and moisture.
- They reduce allergies and respiratory problems caused by dust and mold.
- They contribute to energy savings, especially in the winter months.
📐 How Do We Calculate the Number of Dehumidifiers?
The number of dehumidifiers you need depends on several factors:
1. Size of the house
- For a small apartment (up to 70 sq m), a powerful dehumidifier in a central location is sufficient.
- For medium-sized homes (70–130 sq m), it is recommended to use 2 dehumidifiers, e.g. one in the living room and one in the bedroom .
- In larger homes or single-family homes, it is best to place a dehumidifier per floor or even in each damp room.
2. Layout & open spaces
If the house has an open plan layout, a dehumidifier with a large coverage (e.g. 40–50 liters/day) can cover multiple spaces.
3. Areas with increased humidity
Some spaces definitely need their own dehumidifier, such as:
- Underground
- Laundry
- Bathrooms without windows
- Rooms with lots of plants or aquariums
🧭 Tips for the Right Choice & Placement
- Do not place a dehumidifier behind large furniture or near curtains.
- Check the water collection container frequently or invest in a model with automatic drainage.
- Choose a dehumidifier with a timer and humidity sensor for greater energy savings.
🛒 Conclusion: Do You Need More Than One?
If you live in an area with high humidity, have a basement, or a large house, then yes, you probably need more than one dehumidifier. Proper distribution will ensure better air quality, less damage, and a more pleasant everyday life.
