How To Choose The Best Dehumidifiers For Small Room?
Size
- Sizing does matter when it comes to choosing a dehumidifier for small rooms.
- Too small, it doesn’t work effectively and moist air is still your house. Too big, the machine’s productivity isn’t exploited optimally, which is wasteful and bulky.
- To choose the right size of the dehumidifier for a specific room, you should get the exact measurement of this space (Room size = Length x Width), then check its moisture condition. But if you’re a beginner, here is a handy dehumidifier size chart to follow:
Room Conditions (%) | Room Size (square feet) | |||
300 | 500 | 700 | 800 | |
50-60 | 20-30 | 30-45 | 45-50 | 50-60 |
50-70 | 20-30 | 30-45 | 45-50 | 50-60 |
70-80 | 25-40 | 30-50 | 50-60 | 55-65 |
80-100 | 25-45 | 40-60 | 60-70 | 70-80 |
Capacity
- The capacity of a dehumidifier is characterized by the amount of water absorbed per day. The measuring unit is liters or gallons.
- Small rooms under 15m2 should use a dehumidifier featuring 7 liters/day in capacity. For a slightly bigger room within 15m2 to 20m2, the capacity should be 7 to 14 liters/day. If the room is larger than 20m2, use machines with a capacity of over 15 liters/day.
Noise Levels
- This is also an important factor when choosing a dehumidifier, especially for small rooms. Noise levels are chosen due to two major elements – your preference and space it’s going to work in.
- Some machines are suitable for bedrooms and family rooms with a maximum noise level of only 48dB.
- However, many dehumidifiers generate a loud sound of up to 60dB, which is only suitable for warehouses or separate rooms.

Can a dehumidifier dehydrate you?
