Breathing apparatus reports air is polluted (10)

I believe the answer is:

respirator

'breathing apparatus' is the definition.
(respirator is a kind of breathing apparatus)

'reports air is polluted' is the wordplay.
'is polluted' is an anagram indicator.
'reports'+'air'='reportsair'
'reportsair' anagrammed gives 'RESPIRATOR'.

(Other definitions for respirator that I've seen before include "breather" , "protective equipment" , "Breathing apparatus" , "Breathing aid" , "Supplier of clean gas" .)

I've seen this clue in The Telegraph.
