FAQs
Is the KAATSU C4 safe for everyday use
Yes. KAATSU has been studied for decades and is widely used in rehabilitation, fitness, and wellness. The C4 uses our patented Cycle mode designed to maximize safety and comfort during use.
How is the KAATSU C4 different from other KAATSU products?
The C4 is KAATSU’s most durable system, designed for professional and high-frequency use. It features a rugged, water-resistant build for indoor or outdoor environments, and direct control from the device (no phone required). Compared to the wireless B2, which connects via Bluetooth and an app, the C4 offers standalone operation, making it ideal for clinics, teams, and serious users who need precision, durability, and versatility. Check out the Product Comparison page for more details.
Is the KAATSU C4 waterproof?
The KAATSU C4 is water-resistant and built for rugged use, but it is not fully waterproof. It can safely be used in environments such as rain, snow, mud, dust, or sand—but should never be submerged in water or used while swimming or in a sauna.
How do I know what size AirBands to order
You can view instructions on how to measure yourself on our AirBands page.
Does the KAATSU C4 have Bluetooth?
No. The KAATSU C4 operates as a standalone unit without Bluetooth connectivity. All functions—including selecting modes, adjusting pressure, and running sessions—are controlled directly from the device, ensuring reliable use in any environment without needing a smartphone or app.
