How do I know if I have poor ventilation?

If your home has a lot of condensation on the windows, problems with mould in the corners of bedrooms and is generally stuffy, the chances are you have a problem with ventilation. If you live in a new dwelling with MVHR and the air is very dry or you have similar problems to the previously mentioned, the chances are you have a ventilation problem.

What can be done to ensure I have adequate ventilation?

If it’s a new house or apartment, ask to see the independent ventilation verification cert. Ensure all vents are open and clear. Do not block vents. Open the windows every morning to purge the house with fresh air. avoid drying clothes inside if possible.
