Is My Filter Damage?

Brand new to growing, so this is my first filter. It’s a Vivosun 6" x 18". From the pictures you can see the inside has a bulge where you can see from the other pictures where there is a small indentation on the outside. Wasn’t sure if this is just from how the casing is put together or if it’s actually damaged. Also is it normal for some charcoal dust to come out while unpacking and on the filter cover? Should I wash the cover before using?

Your cool. just make sure air cant sneak by the dent without passing the carbon in its way out. They need a filter to protect the over $100 fan for the carbon. I don’t even use the covers normally.

Some of the carbon does leak out, but I would use the prefilter, so it keeps the dust from going into the carbon, extending service life.

I left the cover on the drying tent filter but airflow is going out.
