We make every effort to ensure that your purchase arrives in perfect condition and shipping is fast and efficient.

Shipping Policies

At this time, we offer shipping of purchases to U.S. customers only. We are not able to ship outside the United States due to additional taxes and fees imposed by customs. 

We offer shipping through UPS and USPS carrier services. The shipping rates are calculated based on weight and distance to your address from our warehouse in Fairfield, CA and are determined by the carrier. Essential Oxygen does not profit from shipping fees and shipping costs are passed through to the carrier.

How our tiered shipping costs benefit you

Because shipping liquid products can be more expensive due to their weight, Essential Oxygen has a tiered cost structure to help offset your shipping costs.This tiered structure ensures the highest level of product quality and customer service.

FREE SHIPPING ON ALL ORDERS OVER $75*: Purchases of $75 or more, excluding wholesale orders, automatically qualify for free UPS Ground shipping to any continental U.S. location, not including Alaska and Hawaii (after promotions and discounts are applied).

*For Wholesale shipping terms, please refer to the wholesale product pages for more details.

Please allow 3 – 10 business days for your order to arrive, depending on your location and selected carrier. Orders are processed Monday – Friday 7am to 3:30 pm PST (excluding holidays). Orders placed after 3:30 pm on Fridays and over the weekend will be processed promptly the following Monday.
