Cair+ Air Quality Monitor for Home - AQI, PM2.5, PM10, CO2, TVOC, Temperature & Humidity With WiFi & Mobile App Enabled

You can set it up in any indoor space — master bedrooms, family living rooms, kitchens, or baby nurseries. It weighs just 175 grams and measures 11 cm x 7.5 cm x 3.4 cm, resting comfortably on a nightstand, kitchen counter, or office desk. A built-in 1600 mAh battery powers untethered monitoring for up to 3 hours per charge, allowing you to unplug the unit and carry it room to room to identify which living areas suffer from the highest pollution levels.

The device includes a dedicated Ventilation Score within its AI Health Index, rated 0 to 10. The monitor calculates this rating directly from real-time CO2 readings in your room. Whenever CO2 crosses 800 ppm, the device signals that fresh air circulation is insufficient. By contrast, a well-ventilated room typically stays below 600 ppm. This score provides a clear, actionable metric, so you never need to interpret complicated parts-per-million figures on your own.

Yes, and this represents one of its most practical features for residential homeowners. The device incorporates an electrochemical sensor engineered specifically for HCHO (formaldehyde) detection. Formaldehyde off-gasses heavily from new wood furnishings, composite particle boards, fresh wall paints, and renovation glues. Levels above 0.1 mg/m³ are classified as Unhealthy, while concentrations exceeding 0.35 mg/m³ are labeled Hazardous. Place it in a recently remodeled space to confirm when the room is completely safe for your family.

No. The Cair+ connects seamlessly to your home Wi-Fi network and uploads data straight to the AQI mobile app, available on Android and iOS. You can monitor air quality in any room right from your phone, whether relaxing in another room or away from home. The companion app also retains historical data across several months, helping you identify trends like nighttime bedroom CO2 increases caused by closed doors and windows.

Yes. The AQI mobile and TV apps connected to Cair+ display your indoor measurements alongside outdoor ambient data from local air monitoring stations. When outdoor PM2.5 is higher than indoors, as commonly occurs on dusty days or during winter temperature inversions, the system guides you to keep windows closed and run an air purifier instead.

Yes. The unit features a Filtration Score in its AI Health Index, reflecting how effectively your air purifier cleans room air. Beyond this rating, you can watch particulate levels drop before and after turning your purifier on. The Historic Graph screen displays the reduction in air pollutants over time, giving you direct confirmation that your home purifier is making a measurable difference.

The monitor is designed with domestic home decor in mind. Finished in an attractive ivory casing with a color LED display, it offers five screen display modes. One option is a Clock/Screensaver mode that turns the monitor into a digital clock displaying live AQI, doubling as an appealing home display piece rather than industrial equipment. It blends seamlessly into a living room, bedroom nightstand, or study desk across your home.

It charges via a standard Type-C USB cable, the identical connection used by modern smartphones and laptops, so you never need a specialized charger. The 1600 mAh internal battery provides up to 3 hours of cord-free use, but the device can also operate plugged in around the clock, making it perfect for continuous placement on a bedside table, desk, or kitchen counter every day.

The Cair+ rates CO2 concentrations above 1,000 ppm as Unhealthy. Bedrooms frequently reach this concentration overnight when windows remain closed, as do compact living rooms occupied by multiple family members. At this level, the device warns of poor ventilation and advises opening a window. Concentrations above 1,500 ppm are considered Hazardous and are associated with headaches, drowsiness, and reduced focus in homes without an air monitor to identify the source of stale indoor air.

Yes. The device satisfies LEED v4.1, WELL Building Standard, WHO, and ASHRAE indoor air quality guidelines. These rigorous benchmarks are standard in certified commercial buildings and medical facilities. For residential homeowners, this means pollutant thresholds reflect verified international health guidelines. Prana Air has also conducted correlation studies comparing Cair+ against reference BAM instruments, confirming measurement accuracy equivalent to professional monitoring hardware used by institutional auditors across diverse environments.

The monitor is deployed across leading organizations, including Delhivery in logistics, Wipro in technology, Canara Bank in finance, Eros Hotel in hospitality, Hyderabad Eye Institute in eye care, and research bodies like IISC Bangalore, CEEW, and the World Health Organization. When top medical institutions and scientific research centers rely on the same monitor you purchase for your home, it confirms the device's build quality, accuracy, and engineering reliability across everyday living spaces for your family.

Yes, which is why it is an ideal choice for households caring for seniors, young children, or individuals with respiratory conditions. Hyderabad Eye Institute deployed it to maintain clinical air purity in surgical environments, where minute shifts in dust or TVOC could compromise patient recovery. For homeowners, that same fine sensitivity across PM1, PM2.5, PM10, HCHO, and TVOC provides hospital-grade visibility into the atmosphere your family inhales daily inside every single room.

Large corporate offices with central air conditioning face steady CO2 buildup, chemical off-gassing from furniture and carpeting, and particulate matter that recirculates endlessly. These factors reduce employee alertness and daily productivity. Wipro and Canara Bank use Cair+ to track these parameters continuously across their floors. For homeowners, the same logic applies: if your home has sealed windows or new furnishings, the unit identifies hidden air problems before they affect health or sleep quality in daily life.

Yes. IISC Bangalore (Indian Institute of Science) and CEEW (Council on Energy, Environment and Water) operate in fields where empirical data precision is paramount. Their adoption of this monitor demonstrates that it meets the rigorous benchmarks needed for scientific investigation. Published BAM correlation data confirms this performance. For a homeowner, it means CO2, HCHO, and dust readings on screen are dependable measurements rather than rough approximations, standing up to rigorous institutional standards.

Hotel guest rooms and domestic bedrooms encounter identical environmental challenges: enclosed spaces, minimal fresh air circulation, chemical off-gassing from furnishings, and CO2 building up as occupants sleep. Eros Hotel utilizes the monitor to ensure guest rooms maintain strict hospitality standards. For a homeowner, bedroom placement offers identical oversight, letting you know whether CO2 crosses 1,000 ppm overnight, whether high humidity creates a persistent mold risk, and whether TVOC levels remain safe while your family rests peacefully throughout every single night.
