Dehumidifier vs mould: what actually works year-round
Damp and mould are not a summer-only problem — extraction capacity and RH targets matter.
Keep indoor relative humidity around 40–60%. Below that, air feels dry; above, mould thrives.
For a typical flat, a 10–12L dehumidifier is often enough. Larger basements need 20L+.
