Commercial Kitchen Hood Filter Cleaning

Cleaning vent hood filters is one of the most time-consuming tasks in any commercial kitchen. Depending on how busy your location is, you may need to do this daily to eliminate the buildup of grease and grime. Scrubbing them by hand is hard work, and running them through the dishwasher consumes a lot of resources. Fortunately, there is an alternative for commercial kitchen hood filter cleaning that saves you time, water and money. The FOG Tank is designed to clean up to 28 restaurant hood filters at once, removing grease and grime without manual scrubbing.

CaptiveAire endorses the FOG Tank® and Tiger Carbon Remover Powder® for cleaning all hood filters used in its hoods, including Captrate® Solo and Combo filters.

Compared to traditional hood filter cleaning solutions, FOG Tank is the superior choice in a wide range of environments. Once you add the Tiger Carbon Removal Powder, you can go for 30 days without having to change the water or add more cleanser. This saves you a significant amount of water and money over using the sink or dishwasher. Its insulated design means it also maintains an operating temperature of 185 degrees without the need to draw much more power to heat it.

Keeping your restaurant’s hood filters clean is important for a number of reasons, including:

• Removing grease and grime that can create an unsanitary environment in your kitchen
• Extending the lifespan of the filter to save you money over the long run
• Improving air quality in your kitchen to protect the health and safety of your employees
• Removing grease buildup from removable filters as part of routine fire safety maintenance

FOG Tank is available in many different sizes, including the largest model capable of handling up to 28 standard-size hood filters at the same time. To learn more or order yours today, get in touch with our team.

Regular maintenance matters as much as the cleaning method. Inspect removable hood filters frequently and clean them when grease accumulates. The right frequency depends on cooking volume, the type of food prepared, and how quickly the filters become soiled. Keep a separate inspection and cleaning schedule for the hood, ducts, and exhaust fan.

The FOG Tank cleans removable metal filters from commercial kitchen hoods. Remove the filters from the hood, place them in the tank to soak, then rinse away loosened grease and residue. Allow the filters to dry before reinstalling them.

You can soak multiple filters in one batch. How many fit depends on the tank model and the size of your filters. Filters with heavier grease and carbon buildup need more soak time; as noted above, hood filter cleaning typically takes 45 minutes to 4 hours.

Cleaning the removable filters is one part of maintaining a kitchen exhaust system. The tank does not clean the hood canopy, ductwork, or exhaust fan, which need to be cleaned separately.

We weighed two dirty hood filters from the same bank before and after cleaning. See the results below:

These photos show the same removable metal hood filter before and after cleaning with the FOG Tank. Grease buildup on the filter is visible before cleaning, while the metal surface is visible after soaking and rinsing.

“I am amazed at how well the FOG tank deep cleans my hood filters. With just a two-hour soak the tank removes all the fats, oils and grease from inside the baffles and they are sparkling clean. My filters are more efficient and I am saving lots of money on chemicals, labor and hot water”
