Where Technology Meets Home Aesthetics
The Kohagoki 7L Oxygen Concentrator isn’t just a functional device—it’s a seamless extension of your home. We believe that wellness equipment shouldn’t disrupt your interior design or your peace of mind. That’s why Kohagoki combines advanced air separation technology with a minimalist, sculptural form that complements modern living spaces.
Crafted with a premium matte white finish and softened organic curves, it moves away from the clinical look of traditional machines. Instead, it feels like a high-end speaker or a designer lamp—something you’d proudly display on your side table, not hide in a corner.
Whisper-Quiet Companionship
True comfort lies in what you don’t hear. The Kohagoki operates at an ultra-quiet ≤42dB—quieter than a whisper or the rustle of turning pages. This means it can run beside your bed while you sleep, or next to your sofa while you watch TV, without ever interrupting your moments of rest or focus. It’s a silent partner in your daily wellness routine, working tirelessly in the background so you can live your life undisturbed.
Powerful Yet Compact
Don’t let its petite footprint fool you. Measuring just 10.8″×8.5″×12.4″, the Kohagoki packs a powerful 7L/min flow rate into a chassis that fits easily on a nightstand, a desk, or a small shelf. It delivers consistent, high-purity output (93% ± 3%) suitable for various personal wellness needs, from post-exercise recovery to daily respiratory support.
The intelligent flow control allows you to adjust from 1 to 7 liters per minute with a simple turn of the dial. No digital menus, no confusing screens—just straightforward, tactile control that anyone in the family can use instantly.
Designed for Real Life
We’ve thought about how you actually live. That’s why the Kohagoki features:
- Integrated Carry Handle: Smoothly curved into the top design, making it effortless to move from the bedroom to the living room as your day progresses.
- Energy Efficiency: Consuming ≤90W, it costs less to run than a standard light bulb, making 24/7 operation economically friendly.
- Stable Base: The weighted black base ensures it stays put on any surface, preventing accidental tipping.
- Simple Maintenance: The washable filter cover pops off easily for quick cleaning, ensuring consistent oxygen output and optimal performance.
