Top highlights Brand Orvetra Color Pearl White Product Dimensions 2"D x 4"W x 3.5"H Item Weight 9.6 ounces Operating Humidity 10% to 90% Sensor Type CO2, PM1.0, PM2.5, PM10, TVOC, HCHO, Temperature, Humidity, AQI 🌬️【KNOW WHAT YOUR FAMILY IS BREATHING】Stale air, dust and chemical fumes are invisible, but this indoor air quality monitor reveals them. Track CO2, PM1.0, PM2.5, PM10, TVOC, HCHO, temperature and humidity on one color screen, with a 0–500 AQI bar that works as an AQI monitor indoors at a glance. More than a CO2 monitor, this home air quality monitor shows in real time how cooking, cleaning or a closed door changes your air, a lasting alternative to a one-time indoor air quality test kit. 🔬【HIGHLY SENSITIVE SENSORS, EARLY WARNINGS】A laser particle sensor and a VOC sensor catch shifts in particles, TVOC and HCHO as they happen, so you'll know when fresh paint, new furniture or a cleaning spray changes the air. Green, yellow and red show where you stand; at red, an alarm sounds and the screen tells you to open the windows. An HCHO meter and TVOC air quality monitor in one, with no guessing and no waiting on a single-use home air quality test kit. 🌙【SLEEP SOUNDLY WHILE IT KEEPS WATCH】Mute the alarm with one press and switch the screen off. Orvetra keeps measuring all night in the dark. If the air turns poor (red), the screen lights up at full brightness to warn you, then returns to your last setting, off or dimmed, once the air is back to normal. Prefer a soft night glow? Choose from 3 brightness levels. At the lowest, the battery lasts up to 12 hours, enough for a full night unplugged. 🔋【TAKE IT WHEREVER YOUR FAMILY GOES】The built-in battery runs up to 12 hours at the lowest brightness and about 8 hours at full, longer than many indoor air quality meters that last 4–8 hours. Palm-sized and about 0.5 lb, this portable air detector moves from the nursery to the home office to the car, so you can run an air quality test anywhere with an air tester for home and travel. The humidity reading also helps you spot damp rooms where mold tends to grow. 📱【PEACE OF MIND, NO TECH HASSLE】A smart air quality monitor that simply works: no app, Wi-Fi, account or subscription, and your data never leaves the room. Switch between °F and °C and set a 12- or 24-hour clock. Each air sensor warms up in 3–10 minutes, and quick-start steps printed on the screen's protective film get you going before you open the manual. Easy enough for everyone in the family. 📦【EVERYTHING YOU NEED, RIGHT IN THE BOX】Orvetra comes with a USB-C cable (3.3 ft), wall adapter, quick-start card and a detailed user manual that explains each reading, its common sources and what to do when levels rise, making this air quality detector an easy air quality tester for home, even for first-timers. Note: the CO2 sensor is highly sensitive, so keep it away from alcohol, perfume and cleaning sprays, which can briefly raise readings. Restart in fresh air to reset.
