If you have not opened your PowerLung, you can return it to the place of purchase for a refund or exchange. If you have opened your PowerLung it cannot be returned for health reasons. Please review our Return Policy for additional details.
If you want an exchange because the PowerLung model you purchased is too difficult or too easy, but you have already opened it, please consider purchasing one of the Resistance Cell Sets for the model you now think would be best for you.
