Contraption is ergonomically keeping air cleaner? (7)
I believe the answer is:
ioniser
'air cleaner?' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I don't see?
'contraption is ergonomically keeping' is the wordplay.
'keeping' says the answer is hidden in the clue.
'IONISER' is hidden within 'contraption is ergonomically'.
Can you help me to learn more?
(Other definitions for ioniser that I've seen before include "Device used to improve air quality in a room" , "Device improving room air quality" , "maybe this would improve air quality?" , "Electrical device purifying air" , "pollution remover" .)
