After a while there was a faint smell of ocean.

But this whole proposition has a faint smell to me.

He realized an odd, faint smell was in the air.

There was a faint smell of burning in the air.

There was the faint smell of a coal fire in the room.

It gave the room a faint smell of times past.

There was even a faint smell of paint in the air.

Even a faint smell of smoke is still in the air.

And now there's nothing much left but a faint smell.

There is a faint smell of gas in the kitchen.
