Every LungZen order is backed by a 60-day, 100% money-back guarantee. If the product does not work for you — for any reason — you get a full refund.
Email support@lungzen-lungzen.com with your order number. Our team sends return details and processes the refund fast — usually within 5 to 7 business days after verification. The credit goes back to your original payment method.
Request must come within 60 days of purchase. Open or sealed bottles both qualify. Return postage is on you unless the product arrived damaged (in that case we cover it).
Email us immediately. We will replace the order or issue a full refund including shipping.
