Hello everyone,

There are already a few DIY projects online for controlled ventilation filter boxes. Since the supply air filter in my system needs to be replaced soon, I want to start this project. The hazel pollen is flying wildly, and alder seems to be making an effort too. I would like to keep both outside.

Unfortunately, images from other forums are now mostly only accessible as Google thumbnails. I will probably start the project today.

Everything has to be somehow squeezed in here:


Heating system in the attic: insulated air ducts, silver flexible ducting, and Vaillant boiler.


Updates to follow.

Half a year later, I changed the filters.

So far, it appears to be completely sealed.
