Do the N95 masks require buying extra filters?

No. They are complete and disposable. Some have a one way valve in them and some don't. They are not like the respirators with charcoal filters that you may have seen. It is probably easier to breath and not steam up glasses with the valve. You just keep using one until it becomes hard to breath due to dirt filling the pores.
