Intake FAQs: All About Intake Sizing

Q: How does Intake’s sizing system work? How do I determine my size range?

A: We get this question a lot. Because of how many ways there are to wear Intake, we have a number of different answers. Read on to learn more.

How the size range works–

Intake comes in three size ranges (Small, Medium, and Large) with two sizes per range (S1 and S2, M1 and M2, and L1 and L2). If you’ve purchased an Intake Kit before, you know that each kit comes with a pair of bands in the same size range. We do this for a couple reasons. One is that most people can fit comfortably within a range of sizes, and like to try out at least two before deciding which works best for them. Something else we’ve noticed is that many of our users prefer to have two different sizes for different activities: one for exercise and one for sleeping, or one for their gym routine and another to wear under goggles or a faceplate (more on this later). Plus, sometimes it’s just nice to have an extra option.

How to best determine your size–

Intake Band Size is measured based on the width of the bottom of your nose (to download our size chart, click here). However, the shape of your nose, as well as the width, may determine which size works best for you. Here are some general tips to get started:

  • We recommend all users start with the size chart and order the size that most closely matches their measurements.
  • If between sizes, we recommend users size up.
  • Once you receive your bands, apply them while watching our application video. If it doesn’t feel like the band is opening your nose, or if you experience discomfort, experiment with moving the tabs up and down your nostrils until you find the best placement for you.
  • Order the wrong size? Email us at and we’ll troubleshoot with you, and get you set up with the band you need.

The best way to tell if you’re wearing the right size is to take a deep breath in through your nose. If you’re inhaling more air than you previously thought possible, then you’ve got the perfect fit!

High impact activities vs low impact activities

If you’re wearing Intake for high-impact activity, or in a sport that requires goggles or a faceplate, we recommend sizing down. A smaller size band will create less pull on the adhesive tabs, making the band more likely to stay put. Of course, your mileage may vary, so we recommend trying out both sizes in your kit to see which is the best fit for you. For use of Intake with sunglasses, there should be no need to change your size from whichever you feel is most comfortable.

If you’ll primarily be using Intake for sleep or lower-impact activities (for instance, a moderate gym set), we recommend choosing your normal size or even sizing up—the larger sized bands are less convex, meaning they’ll pull your nostrils open wider and allow greater airflow. However, this also means they’ll pull harder on the adhesive tabs, meaning you’ll potentially get less run time out of the tabs. You will learn quickly if your skin takes well to the adhesive and you are able to use a larger size, or if your skin prefers the use of a size that is more “perfect” for your nose. If you’ll just be using the bands for sleep, it’s best to opt for a slightly larger size first to ensure you have access to the most airflow.
