Returns & Refunds

A Straightforward Returns Process

We want you to feel confident ordering from DAAI. Because oxygen-concentrator products and related accessories can involve hygiene and safety considerations, returns must meet the conditions below.

30-Day Return Window

You may request a return within 30 calendar days of delivery for an unopened, unused product in its original sealed packaging. The product must be complete, undamaged and returned with all manuals, accessories, gifts and protective packaging. This policy does not limit any mandatory rights available under applicable consumer law.

Products That Cannot Be Returned for Change of Mind

• Products that have been opened, assembled, used, worn or connected for personal use.
• Hygiene-sensitive or consumable items once their factory seal has been broken, including nasal cannulas, tubing, filters and humidifier-related accessories.
• Items damaged after delivery through misuse, accident, improper handling or unauthorised modification.
• Products returned without prior authorisation, missing components or unsuitable packaging.

Damaged, Incorrect or Faulty Items

If an item arrives damaged, is incorrect or appears faulty, contact wul420497@gmail.com within 48 hours of delivery for shipping damage, or promptly after discovering a functional issue. Include your order number, photos or video where appropriate and a description of the concern. We will assess the issue and, where applicable, arrange a replacement, repair, refund or other remedy in line with this policy and applicable law.

How to Start a Return

Email wul420497@gmail.com with “Return Request” and your order number. Do not send any item back without our written return authorisation and return address. Unauthorised returns may be refused or delayed.

Return Shipping and Refund Timing

For approved change-of-mind returns, the customer is responsible for return shipping and any original delivery charge is non-refundable unless local law requires otherwise. If we confirm that the item is faulty, incorrect or damaged on arrival, DAAI will provide appropriate return instructions and cover reasonable return costs where required. Refunds are issued to the original payment method after the returned item is received and inspected, usually within 5–10 business days. Your bank or payment provider may need additional time to post the refund.
