Werk do you know what exactly the material is that you used for dust filtration? I have been having problems with dust killing my temperature sensor in my fan aspirated radiation shield and would like to build a similar protection chamber.

Hi richaam,

I don't know exactly the name of this material. Its a kind of tissue currently used as a filter inside of many covid-19 social masks.

I believe the protection chamber is an important element on a RS. I started to try protection chambers some years ago, on my home made RS, exactly because T/H sensors after more or less one year, started to give unreliable Humidity readings.
