Review: Ultrahuman Home

The Ultrahuman Home is a futuristic-looking home environment monitor that tracks air quality, light, sound, and temperature. All this data flows into the Ultrahuman app on your phone, offering potential insights into your environment and suggestions on how you could make it healthier. Sadly, this mostly amounts to reminders to crack a window open, because most of the touted features are not yet present and correct, despite the rather hefty $550 price.

Ultrahuman made its name with a subscription-free smart ring that made biohacking more affordable (though it may soon be banned in the US due to a lawsuit from Oura). The Home monitor may seem like a strange sidestep, but if you’re going to hack your body, why not your environment? After all, we know air quality, light and sound exposure, and temperature and humidity can impact our sleep and general health.

Setup and Tracking

Taking a leaf from Apple’s playbook, the Ultrahuman Home is a 4.7-inch anodized aluminum block with rounded corners (it looks like a Mac Mini). There’s an Ultrahuman logo and light sensor on top, a power button and LED on the front, and a USB-C port on the back flanked by privacy switches to turn off the microphone or connectivity (Wi-Fi and Bluetooth).

Setup is super simple: Plug it in and add it via the Ultrahuman app. The Home gets its own tab at the bottom of the Ultrahuman app, alongside the ring, and if you tap on it, you’ll get a score out of 100, indicating how healthy your environment is. Scroll down for a breakdown of the four scores that combine to create your overall Home score (air quality, environmental comfort, light exposure, and UV exposure).

To compile all this data, the Ultrahuman Home is packed with sensors:

• Air quality sensors to track things like volatile organic compounds (VOCs), typically released by cleaning fluids, and carbon dioxide levels (CO₂) that might indicate poor ventilation. They also watch out for formaldehyde (HCHO), carbon monoxide (CO), and smoke.
• Particulate matter sensors to track tiny particles in the air, including things like dust, pollen, mold spores, and particles released by cooking. Covering PM1.0, PM2.5, and PM10 (the number refers to the size in microns), the Home warns if you’re in danger of breathing these particles in.
• Temperature and humidity sensors to track how warm or cool it is and how much moisture is in the air. You get a chart of the temperature in your environment and the humidity level.
• Light sensors to track the level of light and also its makeup, including the amount of blue light and ultraviolet (UV) exposure.
• Microphones to track the noise levels in your environment, showing noise in decibels in a chart.

The data is all easy to access and read in the app. You get notifications throughout the day, including alerts if VOC levels spike or there’s prolonged noise. I set the Home up in my office for a few weeks and then tried it for another couple of weeks in my bedroom, after I moved houses. This raises the issue of where to put it, because it must be plugged in and isn’t really designed to be moved around. The bedroom seems like the best bet, but you ideally want both, though I can’t imagine springing for two or more of these to cover all your bases.

The idea of combining body and environment tracking data seems smart, but the Ultrahuman Home doesn’t really do it yet. The touted UltraSync with the Ultrahuman Ring Air is limited to basic common sense advice for now. I don’t think anyone really needs a box to tell them they will sleep better in the dark and quiet, and the air quality advice mostly amounts to opening a window for better ventilation.
