'non-ozonic' is formed in English by the negative prefix 'non-' + 'ozonic', where 'ozonic' derives from 'ozone' (the gas).

'ozone' was coined in the 19th century from Greek 'ozein' meaning 'to smell'; 'ozonic' developed by adding the adjectival suffix '-ic' to 'ozone'; the newer formation 'non-ozonic' adds the prefix 'non-' to negate that adjective.

Initially 'ozein' related to smell; 'ozone' was named for the gas's distinctive smell and 'ozonic' meant 'of or relating to ozone' — 'non-ozonic' later developed to mean 'lacking those ozone-related properties'.
