What if I'm not absolutely crazy about my sound conditioner?

We love our sound machines, and we believe you will too. If, however, you purchase a product from us and find that it just doesn't work for you at all, send it back to us within 30 days and we'll give you a full refund. That's how we roll.

That being said, we do encourage you to give your new sound machine a chance. Some people find that it takes a little time to adjust to using a sound machine, and/or to find the setting, placement, and volume configuration that works best. That's why we've introduced our 90-day Serious Sleep Promise. This extends the return window, giving you plenty of time to fall in love with our soothing sound. Read more about it here. The 90-day promise applies only to products purchased directly from

*Please understand that while we really want to make you happy, you must work with the vendor that sold you the machine. For example, Amazon returns need to go back to Amazon (unless you've received a defective unit and want a replacement - in that case, please do contact us and let us make it right! - this return information applies to returns, not exchanges.)  If you're just not happy with your sound machine and never want to hear it again, here’s what to do:

1. If you bought your product from Marpac, please click here to initiate the return process. We will gladly work with you on the return and refund.

2. If you bought your sound machine from a Marpac dealer, please contact them directly or take it back to the store.
