How Often Should You Have Your Kitchen Hood Systems Cleaned


Cleanliness is a critical activity in every sector and product. Whether it is a Television, sofa set, or a solar panel, regular maintenance and cleaning is the most crucial aspect of several items of daily use.

People cannot ignore the dust accumulated on these items, fixtures, or devices. There are numerous such fixtures at home requiring daily, weekly, or monthly washing or cleaning. One such fixture or device is a kitchen hood system.

Kitchen hood systems are the standard big-sized exhaust fans that take off the steam, vapors, heat, grease, etc., enhancing the overall air quality in the kitchen. These are similar to chimneys, but there is a slight difference between their airflow. The former ejects the particles outside, whereas the latter recirculates the air into the kitchen.

These systems are generally seen in restaurants and clubs where the frequency and volume of food cooked are high. These are expensive. But, there are many companies that provide these systems at reasonable rates.

Frequency Of Cleaning Kitchen Hoods System


The system works strangely due to its complex components. When a complex structure is associated with a product or device, it is essential to note down its maintenance requirements.

A decent kitchen hood safeguards the cooks or chefs against possible fire hazards. The device attracts grease residue very quickly. Therefore, its maintenance is a must. It needs regular cleaning.

However, there is no fixed period after which a person should clean these systems. The frequency of this cleaning depends on various factors like volume of operations, smoothness of carrying activities, model, etc. The two most significant areas in the cleaning process and its frequency determination are shown below.

Cleaning Frequency According To Activity Type


The purpose for which the cooking is done is a significant contributor to the cleaning regularity of the hood systems. For example, a 24×7 restaurant, hamburger, and fast-food outlets will require a cleaning four to six times a year.

The business owners should run a thorough cleaning process by inspecting the device’s small as well as large parts. The following points will give an idea about the frequency of cleaning based on the type of activity.

  • A monthly or weekly cleaning is required for burning wood or charcoal as grease sticks faster to the system.
  • For the purpose of char boiler or wok cooking, four to six times cleaning per year is recommended.
  • Once or twice a year cleaning is required for hoods while cooking in non-grease-creating appliances.
  • Similarly, an annual or semi-annual cleaning is needed for dishwashers, soup vats, and steam kettles.
  • In churches, day camps, and related places, cleaning hoods once a year is more than enough. These are places where the frequency of cooking is very low.

Frequency Of Inspection


There is a difference between the frequency of cleaning and inspection. A business should conduct regular inspections, but cleaning is a rare and planned activity. If a company is not involved in checking the system, it might trigger a severe problem where food quality might degrade.

When the cooking volume is high, the inspection per month and year will increase gradually and vice versa. The following points highlight how often a business should check these devices.

  • Places where solid fuel-cooked food is provided, will require monthly inspection.
  • It is essential for high-volume cooking operations like burgers & pizza companies to perform system checks quarterly.
  • For moderate-volume cooking activities, twice a year inspection is a decent time-frequency.
  • For low-volume activities, an annual inspection is the most appropriate schedule.

Importance Of Regularly Cleaned Kitchen Hood Systems

There are various benefits of having a well-maintained kitchen hood system. It not only pleases any outsider, but also has other vital pros listed below.

Enhanced Air Quality


The fundamental use of the kitchen hood system is to purify the air in the kitchen. It removes infectious and harmful pollutants like steam, vapor, grease, and smoke. In return, it provides good quality air. The employees working in the business do not have to worry about their health if well-cleaned hood systems are used in the kitchen.

Harmful Gas Emission

Cooking activities release various by-products, including carbon monoxide. These compounds are health-degrading agents, leading to breathing problems & diseases. Many people also complain of irritation caused by these pollutants. If a person does not clean the kitchen hood’s holes regularly, the carbon emission may lead to severe consequences like permanent dizziness and even death.

Temperature Maintenance

The basic functioning of the system involves pulling off bad & old air and replacing it with fresh air. This whole process maintains a balance between the temperature. If grease particles block the hood system, there will be a mismatch between the air circulation. If it strikes a balance, it may provide heat in winters and coolness in summers.

Employee Well-Being


As mentioned earlier, grease can lead to high chances of fire spread. The most vulnerable people during such consequences are the employees of the business. Therefore, regular removal of greasy layers will help employees concentrate on their daily operations.

They will be less worried about fire hazards. Furthermore, it is a sign of showing the company’s concern towards their employees, leading to morale-boosting.


Due to COVID-19, particles such as grease can be detrimental to the health of many people. Businesses and restaurants have taken the cleanliness issue of the kitchen hood systems seriously. They involve themselves in daily maintenance in order to avail different benefits of the device.

People have also become conscious about the cleanliness factor of hotels, churches, etc. Therefore, cleaning kitchen exhaust systems has become more of a marketing concern than a health issue. Successful installation and maintenance of these systems will ensure an extended life of the exhaust, lowering unnecessary costs.
