Do Air Purifiers Help with Damp and Mould?

The Short Answer: Yes and No

It is a common misconception. An air purifier **cannot** remove dampness from the air. It does not extract water. For that, you need a dehumidifier. However, an air purifier is excellent at capturing the **mould spores** that dampness creates. These invisible spores are what you breathe in and what cause allergic reactions.

The Perfect Combo

If you have a damp room, the best strategy is a two-pronged attack: 1. **Dehumidifier:** To dry the air and stop the mould growing. 2. **Air Purifier:** To catch the airborne spores already present. Running just a purifier without fixing the damp is like bailing out a boat without plugging the hole.
