Laminar flow hoods and hepa filter must be certified every 6 months. The type of environment that a laminar flow hood provide ISO 5, which is formerly known as a Class 100 area.
You can typically use a laminar flow hood right after turning it on, as it should start providing the clean air flow immediately. However, it is recommended to allow a few minutes for the air inside the hood to stabilize and reach the desired airflow and cleanliness levels before starting your work.
A laminar flow hood should be cleaned regularly using a disinfectant that is compatible with the materials used in the hood. Wipe down all surfaces, including the HEPA filter, shelves, and walls, with the disinfectant. Be sure to follow the manufacturer's cleaning instructions to maintain the hood's effectiveness.
The laminar flow hood should be left operating continuously when in use to maintain the sterile airflow. If it is turned off, it should not be used until it has been running for at least 30 minutes to ensure that the air inside the hood is once again sterile.
The work surface of a laminar airflow hood should be cleaned regularly using a disinfectant solution or 70% ethanol. Wipe the surface gently with a clean cloth or lint-free wipes, making sure not to disrupt the laminar airflow. Allow the surface to air dry before using the hood again.
Filters in a laminar flow hood are typically changed every 6-12 months, depending on the frequency of use and the cleanliness of the environment in which the hood is located. It is important to follow manufacturer guidelines and conduct regular inspections to ensure optimal performance and safety.
The laminar flow hood depends on the laminar air flow to sweep away pathogens from the hood. If there is obstruction, the laminar air flow pattern will be disrupted. The laminar air flow will then change to turbulent air flow.

In a horizontal laminar flow hood, the laminar air flows towards the outside (i.e. towards the worker). There is hence no protection to the worker and it is not suitable for cytotoxic drug preparation. In a vertical laminar flow hood, the laminar air flows downwards from the top, providing more protection for the workers. Vertical laminar flow hoods are hence suitable for preparing cytotoxic drugs.

When working in a horizontal laminar flow hood, you should work at least 6 inches in from the outside edge of the work surface. This is to ensure that the laminar airflow remains undisturbed and effective in maintaining a clean work environment for your experiments.
The work surface of a laminar airflow hood should be cleaned regularly using a disinfectant solution or 70% ethanol. Wipe the surface gently with a clean cloth or lint-free wipes, making sure not to disrupt the laminar airflow. Allow the surface to air dry before using the hood again.
A laminar flow prevents the inappropriate circulation of air within a hood where cells or bacteria are being cultured. This prevents contamination and also insures the safety of the worker
The underlying mechanism of a laminar flow hood in any application, including microbiology is that a roughly non-turbulent flow of air is more effective at preventing cross contamination of materials in the hood and having that air go through a high efficiency filter first is effective in preventing contamination by microbes and other items from outside the hood.
