FAQs

Is the KAATSU B2 safe for everyday use

Yes. KAATSU has been studied for decades and is widely used in rehabilitation, fitness, and wellness. The B2 uses our patented Cycle mode designed to maximize safety and comfort during use.

How is the KAATSU B2 different from other KAATSU products?

The B2 is fully Bluetooth-enabled and tubeless, meaning there are no connector tubes. It is controlled entirely via your smartphone using the KAATSU Connect app for iOS or Android. Check out the Product Comparison page for more details.

Can I use the KAATSU B2 in water or a sauna?

No. The KAATSU B2 controller units are not waterproof and should not be used in pools, saunas, or any wet environment. Always keep the device dry to ensure proper function and safety.

How do I know what size AirBands to order

You can view instructions on how to measure yourself on our AirBands page.

What data is collected by the KAATSU Connect app?

The app records your KAATSU session data such as date and time, duration, mode, and pressure settings. You can choose to share this information with healthcare professionals, coaches, or family members, but your data remains private unless you decide to share it.

Exceptional

"The KAATSU B2s are of exceptional quality, have multiple programs and best in class applications, and their size makes them easy to apply and even to travel with. I struggled over the price for many months, but am now both satisfied I have received value for money and am sorry I waited so long!"

Truly Beneficial

"My age is 88. I incorporated KAATSU into my daily exercise routine. The more I use KAATSU, the more enthusiastic I become about the benefits. I recently started using a pair of the new B2s. The new features are truly beneficial, especially the more powerful compressors."
