Commercial Kitchen Hood Cleaning vs. Filter Exchange: What’s the Difference?

Many commercial kitchen operators ask whether hood cleaning and filter exchange are the same thing. They are not — and understanding the difference is important for maintaining a safe, compliant kitchen in Seattle.

What is Commercial Hood Cleaning?

Hood cleaning is a comprehensive cleaning of your entire kitchen exhaust system. This includes the canopy hood itself, all ductwork running from the hood through the ceiling and walls, the rooftop exhaust fan, and grease collection containers. A proper hood cleaning requires pressure washing with commercial-grade equipment and must be performed on a schedule that matches your cooking volume and fuel type as required by NFPA 96.

What is Filter Exchange?

Filter exchange is a more frequent maintenance service that focuses on the grease filters — the removable baffles inside your hood that catch grease before it enters the ductwork. These filters need to be cleaned or replaced regularly, often every few weeks for high-volume kitchens. Kitchen Guard’s filter exchange program keeps clean spare filters in our service vans so your kitchen never experiences downtime.

Which Service Does Your Kitchen Need?

Both services are typically required. Filter exchange reduces grease accumulation between hood cleanings, extending the life of your system and keeping your kitchen safer day-to-day. Full hood cleaning is required by NFPA 96 on a schedule based on your cooking volume. Most commercial kitchens in Seattle need quarterly hood cleaning plus monthly filter exchange.
