If light can pass through an object, or if you can see through it, it is transparent.

Is there a similar word for "air can pass through", or you can breathe through an object? This adjective would be used to describe a screen door, or certain types of fabric.

Best Answer

permeable if the pores are small

I don't know what to call this property in a screen door...

apologies to @James McLeod - I didn't read the entire question and jumped on permeable.
