Warranty / Return Policy


We offer an industry leading 3-year warranty on our device. The 3-year warranty covers the main Flyp Nebulizer unit (excluding HypersoniQ Cartridge, mouthpiece, and charger). Convexity Scientific warrants the covered product to be free from manufacturing defects for a period of 3-years. If a covered device is found to have an issue – performance or otherwise – resultant of a manufacturing defect, the device will be replaced at no charge to the customer. Convexity Scientific reserves the right to request that the covered device in question be returned to our facility for testing in order for a proper determination to be made and that the customer may be responsible for postage related to any exchanges or replacement.

Note: Damage resulting from failure to properly care for the device, including lack of cleaning, exposure to extreme conditions, physical trauma, or using a non-approved charger, among others does not constitute a manufacturing defect.

To initiate a return, you must receive a return merchandise authorization (RMA) from our customer service team.

Refunds on Unopened Products: Upon receipt of qualifying returns and a subsequent reasonable examination of the returned products, your refund for unopened items will be authorized. Refunds will normally be credited to the same account debited during the purchase. It can take up to 2 billing cycles for a refund to be processed and cleared, depending on your credit card company or bank. All issues with devices, cartridges, and accessories purchased through a retailer must be addressed with the retailer based on the retailer's return policy.
