The main purpose of this flow hood is to limit/prevent debris from falling onto your workspace. For example, when one is doing a transfer from one agar dish to another, doing it in front of this flow hood will make it less likely for debris/contaminates from falling inside. If this price point is a bit expensive, you can opt for a still air box (sab) and get results reasonable for a small scale grower.
