Do the magnets go inside your nose?

Absolutely not! We designed this system to sit comfortably on the outside of your nose, with zero invasive pieces. The AC Nose Strips stick to the outside of your nose and they have built in steel discs which the magnets in the AC Band snap to when applied. Please watch the application video to see how easy it is to use our system!

Why do I need this system? 

There are life changing benefits to nose breathing! The problem is, once you are breathing your hardest, your nose naturally collapses upon inhale and you simply cannot sustain proper breathing technique.  The AC System holds your nose open far past its natural capacity using our patented magnetic design so you can breathe correctly throughout your workout. For more information on the science behind nose breathing, click "Why Do I Need This?" above. 

What size band am I?

We are currently working on becoming Intake Breathing. This change will come with an all new size range, a travel case, a subscription, and so much more.  Visit to join the email list for all the updates and to get up to 50% off upon launch! For now, we have a couple recommendations for the AC Systems products- 1) If you are in doubt- go with a smaller size.  Most people wear a 0 or a 1.  Even if you feel that you could probably wear a size larger, you will still experience incredible benefits with the smaller size. 2.) If you are planning on using your band under a goggle, such as motocross, ski, snowboard, etc. we highly recommend going as small as a 0 for most users. The smaller size doesn't pull as hard on your nose, therefore it holds more securely and reduces the likelihood of getting knocked off during intense movements. Some googles work better with the system than others. If you are planning on using it without a goggle, such as at the gym, running, cross fit, etc. you may prefer a slightly larger size to fully experience the benefits of the incredible pull the magnetic system creates.

International shipping?

We are currently shipping only within the US, Canada, Europe, Australia, and New Zealand. International distribution and logistics can be challenging and expensive. USPS is the cheapest option but can be less reliable and slow (up to 21 business days). DHL is expensive but they are a much faster (3 business days) and reliable service.

Does the band come in different colors?

We originally designed our bands in black due to its non reflective nature, similar to Eye Black that football and baseball players use.  However, we fully intend to have multiple colors available in the future! 

How long will it take to get my order? 

Orders typically ship within one business day.  Within the US, we use USPS- giving you the option to choose between first class mail (3-5 business days arrival), priority mail (2 business days arrival), or priority mail express (1 business day arrival). See "International Shipping?" above for international information.

What payment options do I have?

We are currently accepting credit and debit cards as well as paypal.
