Return Policy

At Delta Adsorbents, we guarantee our products; if an item has not met your expectations, you can bring it back. Unlike most retailers, we also guarantee the product selection advice offered through our catalog, website, and staff; if an item you've purchased based on this advice turns out to be unsuitable, you can bring it back. In either case, simply return the item for exchange, refund, repair, or credit. 

If you have any questions about our guarantee, please, email us at customerservice@deltaadsorbents.com or call us at 630-980-5205.
Returns and Exchanges
Returns and exchanges can be made by mail. Please call our Customer Service Center, if you wish to return or cancel an order placed online.
Returning by mail
Within the US: Returned items must be sent via insured, prepaid Regular US Mail. Ensuring your return allows you to track your parcel with the US Postal Service. 
Please Note: We cannot accept CODs or courier deliveries.
Outside the US: Ship goods prepaid, by insured ground shipping. To avoid unnecessary delays, please write “U.S. Goods returning” on the outside of the package. 



Please Note: Do not return items by UPS or other carriers, as duty and / or brokerage fees will be charged, and your return will be refused by Delta Adsorbents.
If you are requesting an exchange, please remember to include sufficient payment for the return postage. Where applicable, please contact your local customs office for information about any taxes or duties that may be assessed on a return shipment.
