When you toss a disposable into a bag with keys and coins, it can end up sideways or upside down. That's asking for trouble: e-liquid can pool in the mouthpiece or block the airflow, causing gurgling and spit-back. It also makes the device work harder, which drains the battery faster.

Make it a habit to store your vape upright. Most devices have a flat bottom, so standing it on a desk or in a cup holder works fine. And once a week, take a dry cotton swab and gently clean the mouthpiece and airflow holes. You'd be surprised how much lint and pocket dust collects there.

A clean airflow path means smoother hits and less strain on the coil—both of which extend the device's life.
