A dehumidifier works best when it can manage the moisture throughout your home, rather than just one room. As moisture naturally moves through your home, a centrally placed dehumidifier can help bring humidity levels down across the whole property. This can help reduce condensation, limit mould growth and make your home feel more comfortable and easier to heat. For the best results: Place your dehumidifier in a central area, such as a hallway or landing. Keep it running regularly, ideally 24/7 when needed. Keep internal doors open so air can move freely around your home. Keep external doors and windows closed while the dehumidifier is running.
