Because he didn't actually adapt to it, he had to hold his breath the entire time he was there since he is unable to survive in space.

He was fine for a short amount of time, but he is still human and requires oxygen in order to survive.

Its ones of the few weaknesses that saitama actually has. and the author pretty much confirmed it.

If saitama hadn't held his breath during the time he was in space then he would have died (even though holding your breath in space actually makes things worse for you.).

He did not adapt to space and he cannot adapt to it. Thus he is not a user and never will be.
