Mesosphere
the layer above the stratosphere, not enough gass to form ozone, so O2 just breaks into O and eventualy reforms, Filters UV-C

why te ozone layer is in the stratosphere
forming ozone requires aditional molecules to cary away the heat, requiring a certain concentration, but eventualy the ozone filters out all the UV-B
