Vertical vs horizontal flow laminar flow hood

[Cashinked]

Which would be better for brewing Purpose ? I was thinking with a vertical air is being pushing into the empty vials , but horizontal it would be better for our application ? What do you guys think

I will be honest, i know and understand the benefits but i dont think a flow hood is essential if a little common sense is followed

If you have a concern bout room sterility buy an air purifyer like those doctors use when they make surgery. That will help.
Wear a mask
Use alcohol for cleaning the room.
Use steri gloves
The most important thing is u need to be sure that u have steri vials.
