What Is a Portable Dehumidifier and How Does It Work?
| Step | Description |
|---|---|

| 3. Water Collection | The condensed water drips into a reservoir or is drained away through a hose. |
| 4. Dehumidified Air | The dry air is then heated slightly and released back into the room, reducing overall humidity levels. |
| 5. Energy Source | Portable dehumidifiers typically operate using electricity, which powers the fan and compressor. |
| 6. Humidity Control | Many units come with built-in humidity sensors and settings to maintain desired humidity levels. |
