Hi, I am looking for advice, we have recently moved into a downstairs bedroom which has been decorated. it's an old house which had damp caused by condensation. since we have moved downstairs my asthma has been playing up, I am fine when sleeping but the rest if the day my chest is tight. I have bought a humidity meter and it reads around 70% in the mornings, buy wother use of a dehumidifier I can reduce this to around 50 during the day. I have also bought an air purifier but have used it 2 nights now with no effect, im stuck now on what to try, any advice?
