Plenty of US rentals have no air conditioning, and a small space heats up fast. You can still stay comfortable with the right fan, smart use of curtains, and a few airflow habits. Here is how to keep a small apartment cool without AC.

## Use a fan the right way

A quiet tower fan moves air where you need it, and pointing one out an open window in the evening pushes hot air out while a second pulls cooler air in. A bladeless DC fan does this without keeping you awake.

## Block the heat at the window

Most heat comes in through sunny windows. Thermal blackout curtains drawn during the hottest part of the day keep a room measurably cooler, then open them once the sun moves off.

## Keep the air moving and clean

Stagnant air feels hotter. Running a purifier or fan keeps air circulating, and clearing clutter from in front of vents and windows helps the whole apartment breathe.
