Trace the source before choosing equipment
Observe whether odours arrive when cooking increases, a kitchen door opens or extraction changes. Ask the responsible facilities team to inspect the extraction and air movement.
Do not use a purifier to conceal a ventilation fault or a potentially unsafe combustion problem. Repairing the source can matter more than adding equipment in the dining room.
Separate particles from gases
HEPA particle filtration and activated carbon perform different jobs. clean air delivery rate (CADR) describes particle cleaning, not a guaranteed rate of odour removal. Gas removal depends on the specific media and the gases concerned; a thin carbon layer should not be treated as a universal odour solution.
Ask what performance evidence and replacement criteria support the proposed use.
Trial only after the basic controls are addressed
Place equipment where intakes remain clear and service access is practical. Record the fan setting, dining-room layout and cooking conditions when collecting staff feedback.
A change in perceived smell is subjective and does not demonstrate that all pollutants have been removed. Budget for the appropriate filter media and keep a replacement record.

Your planning worksheet
A decision table covering extraction, source control and suitable purifier functions. On small screens, scroll the table horizontally.
| Observation | First action | Purifier role |
|---|---|---|
| Odour escapes when cooking increases | Check extraction and source containment | Supplement after the cause is assessed |
| Airborne particles in an enclosed dining room | Review source and ventilation | Particle filtration sized to the room |
| Persistent gaseous odour | Identify source and relevant gases | Consider supported gas-filter performance |
| Open doors and uncontrolled airflow | Assess the airflow path | Do not promise whole-space treatment |
