Use a dehumidifier
Purchasing a dehumidifier can also help reduce the amount of moisture in the air.
Place the dehumidifier near the windows where you see condensation most often.
Make use of a fan
In rooms such as the kitchen or bathroom, ensuring your fan is switched on can help to reduce the risk of condensation buildup.
Ventilate
Although opening your windows might not be the most desirable option in the winter months, it can work wonders to help banish condensation.
Try to do this when you are cooking, in the shower or even when you are in bed.
Opening your windows for just 20 minutes a day can help to reduce the effects of condensation.
