Airing a house - do you need to open all the windows at the same time?

[ScreamingBeans]

Or can you just open some of them for 15 minutes, close them, then open others for another 15 minutes etc?

Or does it have to be all at the same time?

It doesn't have to be at the same time. It's often good to open bedroom windows for a bit in the morning to get rid of fusty overnight air but do what feels best for you.

It's not a science with rules,,do whatever works for you.

Is there a reason you need to ask, it's not something that's evena thing is it? Ii ft's nice and warm or a room seems musty I just open the windows, I've not given any thought to there being any kind of system

I open all the windows in my house first thing for a few hours

If you open a lot of windows you’ll have a faster through flow of air so it’ll change the air in your house quicker - but also be colder and you’ll end up with doors banging all over which is annoying! I tend to try and open the window of every room at least once during the day but it’s just when I feel it’s a bit musty.

The reason I ask is because i read a ridiculous article and started to question everything. I've always opened windows as a norm but not all of them especially not in Winter.

Why do you feel the article is ridiculous? It makes sense to me and I have found it works really well

Just open when you can and as needed. I haven't got time to go round opening and closing all ours every day before work (and my DCs would object if they are still in bed). So I just open ours for half an hour and the patio doors in the kitchen while I have breakfast. Bathroom one when people are showering. Others open as and when it suits.

@ScreamingBeans Do you live in Germany? Their climate is somewhat different from ours.

Just open doors / windows at random whenever you feel like it.

I leave a small window open in all the bedrooms all the time, day and night, whatever the weather, even in winter they're open a small amount. From this time of year till autumn I open at least a small window in every room downstairs all day. My heating bills are normal and my house always smells fresh and I never have condensation, mould etc. I absolutely hate a stuffy house where windows are rarely opened and the air is fusty.

Because it uses the German word luften, as though the English simply don't have a concept for the idea of airing a room.

It isn't a ridiculous article. Luften is German for to air or ventilate. Of course the English have a concept of and language for it.

Just open a few windows for a little while each day to get air flowing. We have small windows in the bedrooms open a fair bit of the time including just a little crack overnight.

Open a small window just a few inches in each room for a little while when you get up. It ventilates the house without letting it get too cold and will reduce condensation and mould.

We have the bathroom window and our bedroom window open all the time , small bedroom where the heated airer sits open a bit.
None open fully as we don't want the cats getting out ( they can use their catdoor)

Makes a huge difference year round
