If you need a replacement due to defective or damaged device, we will replace it with the same item you originally purchased. To be eligible for a replacement you must contact us to receive a Return Merchandise Authorization (RMA) form. To obtain an RMA form please call our Customer Care team at (833) 692-3883 to speak with a representative you can email us directly at contact@baeus.us, which will start the process of returning your Biotica device directly to Better Air USA to exchange your unit.

You will be responsible for paying for your own shipping costs for returning your item. Please be sure to send the product back in the original packaging with all the accessory parts properly packed. If the seal is broken on the probiotic cartridge, you do not need to return it. If the original packaging is no longer available, please pack it in an appropriately sized box with bubble wrap to protect the device from any further damage that may occur during the return shipment process.

Once your product has been examined and approved for replacement, you will be notified via email of when your new shipment will arrive.

Return shipping costs are non-refundable.


Once your return is received and inspected, we will send you an email to notify you that we have received your returned item. We will also notify you of the approval or rejection (with reasons why) of your refund.

If you are approved, your refund will then be immediately processed and a credit will automatically be applied to the credit card or original method of payment, within 2-7 business days.


If you haven’t received your refund within 2-7 business days of the approval date, please examine your bank statement or credit card statement to ensure it has not been posted. Then contact your bank or credit card company directly as it may take some time before your refund is officially posted to your account.

If you’ve done all of this and you still have not received your refund please contact us at (833) 692-3883, (Mon–Fri 8am-10pm EST – Sat/Sun 10am-4pm EST)
