These were the glass screens I got. Too small to use with the cooling unit. Last night I was able to get one to sit tightly in the tip of the WPA I linked earlier though. So it sort of works now, but herb likes to get sucked up the the screen and away from the oven. Not great. A larger glass screen would be much better.
I also use the ceramic ones. They tend to not get lost as easily as the nearly invisible glass ones.
I use an IH by the way, haven't tried those screens with a torch. I got popcorn taste all the time when i used an apollo2. I now use one of those cheap asian ones (vapeheater), that's sold in Europe under a bunch different brandnames, and it does its job so much better than the apollo ever did.
I got the screens and the vapeheater at the same time, so im not sure which of them did the trick, or if it was the combination.
