Many well-meaning people invest in a good air purifier but unknowingly make small mistakes that keep it from doing its job. Here are some of the most common:

• Using it only occasionally—clean air isn’t a one-time fix. Keep your units running consistently.
• Putting it in the wrong spot—tucking it behind furniture or too close to a wall restricts airflow.
• Choosing the wrong size unit—a small unit in a large room just can’t keep up.
• Skipping filter changes—a dirty filter clogs the system and stops working.
• Turning off units at night—this is when your body is recovering. You want clean air while you sleep.

Being aware of these habits makes it easy to correct them. Your purifier is one of the most valuable health tools in your home—but only when it’s used the way it was designed to be.
