Avoiding damp, mildew & black mould

I’ve had all sorts of problems in my house recently, including mould, and I’m thinking of getting an air purifier: not to use all the time but just every so often. It isn’t something I’ve ever considered getting before and I’m not sure how necessary or even safe they are but I feel as if m house needs blitzing in some way!

You said you have humidifier / fan. It should be a dehumidifier to prevent mould.
A lot of people emphasise ventilation, but opening windows when the humidity level outside is 90% + is only bringing cold, damp air into the house.
Use extractor fan in kitchen, bathroom to remove moist air. Some level of heat is needed in house and a dehumidifier is definitely useful.

Thank you! We do have a combo humidifier/fan, but it’s currently in hospital with her - I might get one or two for other rooms as well.

a dehumidifier really does suck the damp up and takes the moisturer out of the room.

also keepventilaion going, windows open is important

i hope Mrs Amber Spyglass recovers well soon.
