Vertical flow hoods should typically be inspected at least once a month to ensure proper functioning and maintain sterility. Additionally, they should undergo a thorough certification or performance validation annually, often conducted by a qualified technician. Regular maintenance, such as filter replacement and cleaning, should also be performed according to manufacturer guidelines or when visual inspections indicate a need.

What difference horizontal flow hoods an vertical flow hoods?
Horizontal flow hoods direct airflow horizontally across the work surface, providing a barrier between the user and the work area while allowing for greater visibility and accessibility. In contrast, vertical flow hoods direct air from above the work surface downwards, which can be more effective in preventing contamination from particles falling from the air. Both types aim to create a sterile environment, but their airflow patterns serve different operational needs and preferences. The choice between them often depends on the specific application and workspace requirements.
