HSA and FSA Eligibility of Ultrahuman Products

The Ultrahuman Ring AIR is always eligible for purchase with a Health Savings Account (HSA) or Flexible Spending Account (FSA). That means you can use your HSA or FSA card directly at checkout — no Letter of Medical Necessity required.

Other Ultrahuman products, such as the new Ultrahuman Home, may require a Letter of Medical Necessity. You can also purchase eligible items out-of-pocket and submit them for reimbursement.

At Flex, we’re on a mission to make health and wellness more accessible by helping you use your tax-free HSA/FSA dollars at the best brands in the space. Our partner Ultrahuman, a cutting-edge healthtech company, is redefining how we interact with our environments to improve metabolic and cognitive performance.

With Flex, you can use your HSA/FSA funds to purchase Ultrahuman Home and Ultrahuman Ring AIR—two powerful tools designed to help you take control of your health right from your living room.

What Is the Ultrahuman Ring AIR?

The Ultrahuman Ring AIR is a sleek, sensor-packed wearable that helps you understand and improve your health across key areas like sleep quality, recovery, metabolic health, and daily readiness.

The ring captures real-time biometrics — including heart rate variability (HRV), resting heart rate, skin temperature, and movement — and transforms them into personalized insights through the Ultrahuman app. Whether you’re training hard or just trying to sleep better, the Ring AIR keeps you in sync with your body.

Why Use a Health Tracker Like Ultrahuman?

Tracking your health data is no longer reserved for elite athletes or biohackers. Devices like the Ultrahuman Ring AIR make it easy to monitor important signals and build habits that can improve long-term health outcomes.

Here are just a few benefits:

  • Optimize recovery and performance: Use HRV and sleep data to avoid overtraining and improve your workout routine.

  • Get deeper rest: Track sleep duration, disturbances, and recovery to build habits that support better sleep.

  • Monitor stress and readiness: Understand when your body needs rest or when it’s primed to perform.

  • Support long-term metabolic health: Some Ultrahuman tools go even further, like the M1 glucose monitor, which provides continuous metabolic feedback.

By turning biometric data into actionable insights, Ultrahuman helps users make smarter daily choices — a core reason why many of their products qualify as health expenses.

What Is Ultrahuman Home?

Ultrahuman Home is a first-of-its-kind smart home device built to optimize the health of your indoor environment. Just like a wearable tracks your body, Ultrahuman Home tracks your surroundings—monitoring pollutants, toxins, temperature, humidity, and more—giving you a complete picture of the factors impacting your sleep, focus, and metabolic health.

Think of it as a metabolic command center for your home. Whether you're focused on improving recovery, reducing stress, or supporting better sleep, Ultrahuman Home provides personalized insights that make it easier to build a high-performance lifestyle.

Ultrahuman Home is a game-changer for anyone serious about longevity, biohacking, or simply creating a healthier living space.

What Ultrahuman Products Are HSA/FSA Eligible?

Ultrahuman makes several tools that qualify for HSA/FSA purchase, either automatically or with a Letter of Medical Necessity (LOMN):

Always Eligible (No LOMN Needed)

  • Ultrahuman Ring AIR
    Tracks sleep, recovery, and metabolic fitness. Covered through the IIAS system — no doctor’s note required.

  • Cardio Adaptability Add-On
    A tool designed to help track and improve cardiovascular performance using adaptive feedback.

  • Voyager Ring Charger
    An eligible accessory to keep your Ring AIR charged and ready.

Eligible With a Letter of Medical Necessity

  • Ultrahuman Home: Ultrahuman Home delivers continuous, real-time insights into environmental health, empowering users to create homes that actively support their well-being. 

What Is a Letter of Medical Necessity?

Some products require documentation from a licensed healthcare provider stating that the item is necessary to treat or manage a specific medical condition. This Letter of Medical Necessity (LOMN) is often used to justify purchases like glucose monitors or advanced tracking tools that aren’t always considered basic medical equipment.

Why Use Your HSA/FSA for Ultrahuman?

Tax savings

HSA and FSA funds are tax-free — meaning your dollars go further when you spend them on qualified medical expenses. That’s like getting a 30–40% discount on eligible Ultrahuman products.

More control over your health

Using your HSA or FSA allows you to invest in preventative tools that support your long-term health goals.

No paperwork (for some items)

The Ultrahuman Ring AIR is always eligible through the IIAS system — no documentation, no reimbursement process, just swipe and go.
