Return Policy

Unopened Items

For unopened items, you may return them within 30 days. Refunds will be issued in the original form of payment, minus any discounts, bank charges (usually 4%), shipping, and a 15% restocking fee. Return shipping fees apply.

If you received a ‘Free Shipping’ order, we will deduct the original shipping cost. The shipping cost would be applicable for both ways.

Please note there might be special circumstances where we might have had to ship from our international warehouse, in which case the original shipping cost from the international warehouse to the destination will be applicable. Return shipping cost, as applicable, from the customer's address to Optimal Breathing's warehouse will also be chargeable.

Store Credit

Beyond the initial 30 days, refunds are not available. However, within 45 days, you can opt for store credit, with shipping fees subtracted, as previously explained.
