Yes. The outdoor environment plays a key role in what happens inside. For instance, if the American Lung Association outdoor air rating is a C or worse, chances are you might benefit from installing an indoor air cleaner. Do you live near a dirt road, an airport, a busy highway or factory?  Do you frequently spray chemicals that kill weeds or bugs; or use lawn fertilizer? Are there trees, shrubs and flowers producing a high pollen count near your house in the spring? All these sources emit particulates and / or gasses that can easily find their way inside your home each time you enter or leave, and cause adverse effects to your health. Do you already have an air cleaner? Be sure to change your filter at the recommended frequencies; more often if your outdoor air environment includes any of the above described.

Be sure to perform regular suggested maintenance to ensure optimum performance and the longest life of your unit.
