I tested the 12L Challenge dehumidifier in my damp Victorian home over winter — I haven’t spotted any signs of mould for the first time in five years

Challenge D015B 12L Dehumidifier on a pink background.

This Challenge 12L dehumidifier review puts this affordable dehumidifier through its paces to see whether it’s possible to get more bang for not-as-much buck, especially for those struggling with damp and mould during the winter months.

Of course, as someone who writes about home appliances and maintenance on a daily basis, I know that the best dehumidifiers are the key to reducing damp and condensation in a home. They can also work wonders to dry clothes indoors in winter. But despite this - and living in a damp Victorian home - I’ve never really had a proper dehumidifier. Instead, I’ve relied on a tiny, cheap dehumidifier with a pathetic extraction rate and one simple on/off button.
