Canopy Cleaning vs Grease Filter Exchange
Grease filter exchange and full kitchen exhaust cleaning address different parts of a connected system. Treating them as interchangeable can leave hidden deposits outside the maintenance plan.
What filter exchange covers
Filter exchange replaces dirty grease-arresting filters with suitable clean filters. It helps organise filter care but does not remove deposits already in the plenum, ducts or fan.
What canopy and exhaust cleaning covers
A clean canopy does not prove that hidden ductwork has been cleaned. Review the plenum behind the filters, duct runs, bends, fan and discharge point within the agreed scope. Inaccessible sections should be identified, not silently omitted. Clean Air Filtration can supply and install duct access hatches where required, with placement and suitability assessed for the system. Confirm whether a quotation means the canopy alone or a broader exhaust clean; the label is not enough.
Why both belong in the plan
Filters capture part of the grease carried in cooking exhaust. Deposits can still collect downstream. Keeping filter care and full-system inspection separate makes it easier to see when each task was completed.
Set the intervals separately
AS 1851 provides the relevant routine-service framework for kitchen exhaust maintenance. The applicable requirements, inspection findings, cooking load and any insurer or building-specific conditions should inform the service plan. Do not assume one annual booking is suitable for every kitchen. Filter condition, manufacturer guidance and cooking load also matter. Do not copy a generic weekly, monthly or annual timetable without assessing the site.
Compare documentation, not just service names
Keep the agreed scope, service date, before-and-after photographs, PDF report, inaccessible sections and recommended follow-up together. A service report documents the work completed; the insurer, auditor or relevant authority determines whether it meets their requirements.
Include other grease-capture equipment where installed
An electrostatic unit has its own cleaning requirements. Ask about electrostatic filter and unit cleaning across different brands and types rather than assuming it is included in a filter exchange visit.
