In this image you can see, from the right, the original ep, in the center the ep with the rotronic sintered steel capsule, on the left the ep with the original capsule but without any protective filter

Aha, now I understand, thank you (and bianco)! So there is a capsule with a separate filter inside it.
I thought the whole plastic part (capsule) was the filter.
I assume the behavior of the sensor changes without a filter (for example, faster response time).
@ypsinine - It's better to remove the filters completely from the Ecowitt WH31EP/WH32EP. Colleagues in Poland have been using SHT35 without filters in Apogee, Davis FARS24H, Barani for almost 2 years and the sensors are still working fine in these covers. The response time without the filter is heaven and earth.
Great information, thank you!
In your climate it is also worth thinking about a comparison shield to the Barani Meteoshield Pro III. I think it may generate more frequent radiation errors in yours, comparing to WMO Screnn Stevenson and Davis FARS24H. There will also be a faster response to FARS at night relative to the passive Barani shield.
We checked in the cold mid-year and in snowy weather the Barani Gen III shield generated significant radiation errors compared to the full-size Stevenson Screnn. The test with the WMO Screnn. coincided with the Apogee TS100 and Davis FARS24H. The Barani showed higher values by up to 1.5-2 degrees in sunny weather, snow and little wind (higher weather relative to the WMO Screnn). The climate here is different from that of Italy and Portugal, hence such shortcomings of the Barani, which the manufacturer does not want to mention anywhere and hides them scrupulously, but good WMO Screnn and active shields expose them.
Yes I am now considering getting another radiation shield. I have been thinking about a proper Stevenson screen because as you say my location (low wind, cold climate, lot of low sun) it may be a better choice than a smaller radiation shield. But I have a hard time finding sellers here in Sweden. I could of course order from somewhere in EU but my knowledge of Stevenson screens are very limited.
Edit: Davis FARS is also a good choice perhaps.
