At Hartfiel Medical quality manufacturing benefits the oxygen therapy patient.

The O2 FRESH nasal cannula cover is the result of thousands of hours of design and testing with our hospital and university partners and are made here, in the United States, in a beautiful, state-state-of-the-art veteran-owned facility.


We've come a long way from 3D printing prototypes at the local library and are happy and proud to share with you the craftmanship that goes into your O2 FRESH nasal cannula cover.

Factory Environment Matters

O2 FRESH nasal cannula covers are 3D printed in a modern US factory and handled during the process by workers who wear masks and gloves.

Trusted FDA-Approved Materials

The biocompatibility certifications of the O2 FRESH nasal cannula cover meets USP Class I-VI and the US FDA guidance for Intact Skin Surfaces. That means the user will not experience any harmful reactions or long terms effects from the material used in the cannula cover and it is safe to touch and handle.

Top-shelf Dishwasher Safe 

Sanitizable, too! The O2 FRESH nasal cannula cover can be cleaned and sanitized.

Extra Processing Adds Value

After printing, each O2 FRESH nasal cannula cover is treated to a special process that adds a texture and shine and seals the material.

Earth and People Friendly 

Certain chemicals like DEHP and those listed in California's Prop 65 can leach out of some plastics and potentially cause cancer or reproductive harm to the user. The material the O2 FRESH oxygen nose cannula cover is made of does not contain DEHP or any chemical listed in Prop 65. It's also reusable.

Tough and Durable 

The O2 FRESH nasal cannula cover performs the way you need it to from first use and every time after. We even had a tester accidentally put one through her washer and dryer. Not a scratch!
