‘Make a huge impact’: How to prevent window condensation – avoid ‘dust mite infestation’

If it is too low, the expert said woodwork may begin to display warping or experience a build-up of static electricity.

Natasha added: “If humidity is too high, you could risk dust mite infestation, problems with air quality and a build-up of condensation on walls, windows and other surfaces. 

“The moisture from condensation can also soak into the wall and cause mould to form. Some signs to look for include water tide marks on the windows and walls, which will stream, causing deterioration of decoration, discolouring of window frames and eventually – the growth of black mould. 

“All of these are a result of poor ventilation and air circulation, therefore it is important to monitor in case it does impact, leading to respiratory symptoms and infections, allergic rhinitis and asthma.”
