Oh I see. Thanks for that tidbit!

It is easily evaporated by warming up the air again by a few degrees above sea temperature, so once it's at indoor temperatures it doesn't make things damp. Is this what you are finding, or is it different that far south

Yes except we don't have any heating, haha. Except for a portable radiator. We haven't quite decided on best approach to heating yet. I want to see how this winter goes with the new windows.

This issue with the fog would be eliminated with whole house with heat recovery.

I still haven't installed trickle vents yet and now I'm wondering if there's such a thing as a trickle vent that will filter out smoke?]]> Retrofitting continuous ventilation after fitting new windows https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17140&Focus=296771#Comment_296771 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17140&Focus=296771#Comment_296771 Wed, 13 Jul 2022 11:15:26 +0100 djh Retrofitting continuous ventilation after fitting new windows https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17140&Focus=296777#Comment_296777 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17140&Focus=296777#Comment_296777 Wed, 13 Jul 2022 19:48:37 +0100 Shevek
Surface mounted one here:

And one that goes over the window head here:

About 40-50 quid each I think.

Filter types here:

The Urbino Select looks to have an activated carbon layer, which is what you need for odour removal. Performance isn't HEPA but not too bad. Remarkable for such a thin filter.]]>
