Hood filter cleaning keeps the baffle filters over your cookline doing their one job: capturing grease before it enters the duct. VentWash deep-cleans filters as part of every hood service and offers scheduled exchange programs — clean filters swapped in on a route, dirty ones taken away — so filters never become the weak point of your fire protection.
Baffle filters are the first line of defense in the exhaust system: their vanes force grease-laden air to change direction, condensing grease into the trough instead of the duct. Clogged filters do the opposite — airflow drops, smoke rolls off the hood into the dining room, the cookline runs hotter, and vapor bypasses into the duct where it becomes fuel. NFPA 96 also prohibits mesh filters in grease applications; if your kitchen still runs mesh, that's an inspection finding waiting to happen.
Between professional cleanings, filters need attention weekly to monthly depending on volume — that part your staff can legally do. What staff can't do is the system behind the filters. Our exchange program removes the chore entirely: on each route visit we swap in freshly degreased filters, inspect fit and condition, and replace bent or burned-through units before an inspector notices them.

For routine upkeep, yes — staff filter cleaning between services is allowed and smart. But dish machines rarely remove baked-on grease from baffle interiors, and staff cleaning never satisfies NFPA 96's requirement that the system itself be professionally cleaned on schedule.
High-volume cooking: weekly, sometimes daily for charbroilers. Moderate volume: every one to two weeks. The moment you see grease dripping from a filter edge or smoke escaping the hood, they're overdue.
