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

You can place it in any room — bedroom, living room, kitchen, or baby's nursery. It weighs just 175 grams and measures 11 cm x 7.5 cm x 3.4 cm, so it fits easily on a bedside table, kitchen counter, or study shelf. Since it runs on a 1600 mAh battery for up to 3 hours on a single charge, you can also unplug it and carry it from room to room to check which area of your home has the worst pollution levels.

The device has a dedicated Ventilation Score as part of its AI Health Index, rated 0 to 10. It calculates this score based on the CO2 concentration in your room — when CO2 crosses 800 ppm (Moderate range), it signals that fresh air supply is insufficient. For context, a well-ventilated living room typically stays below 600 ppm. The score gives you a clear, non-technical number to act on rather than interpreting raw ppm values yourself.

Yes, and this is one of its most practical uses for homes. The monitor uses an electrochemical sensor specifically for HCHO (formaldehyde), which is off-gassed by new wooden furniture, MDF boards, wall paints, and adhesives used during renovation. Levels above 0.1 mg/m³ are classified as Unhealthy, and above 0.35 mg/m³ as Hazardous. Placing it in a newly furnished room or post-renovation space will tell you exactly when it is safe to occupy again.

No. The Cair+ connects to your home Wi-Fi and pushes all data to the AQI mobile app, available on both Android and iOS. You can check pollution levels in any room from your phone — even from another part of the house or when you are away. The app also stores historical data for up to several months, so you can spot patterns like whether your bedroom CO2 spikes every night due to closed windows.

Yes. The AQI app and TV app connected to the Cair+ show a side-by-side comparison of your indoor readings against outdoor AQI data from the AQI monitoring network. If outdoor PM2.5 is higher than indoors — common during haze seasons or dusty days — the data will tell you to keep windows closed and run a purifier instead.

Yes. The device includes a Filtration Score in its AI Health Index that reflects purifier efficiency in the room. Beyond this score, you can track particulate matter levels before and after turning your purifier on. The Historic Graph screen visually shows the drop in pollutant levels over time, giving you direct evidence of whether your purifier is making a measurable difference.

The monitor is designed with home aesthetics in mind. It comes in an ivory finish with a colour LED display offering five screen modes. One of them is a Clock/Screensaver mode that turns the device into a digital clock displaying the AQI — so it doubles as a home display piece rather than looking like industrial equipment. It blends naturally into a living room, bedroom, or study desk.

It charges via a standard Type-C USB cable — the same used by most Android phones and laptops — so no separate or proprietary charger is needed. The 1600 mAh battery lasts up to 3 hours on battery alone, but the device can also run continuously while plugged in, making it ideal to keep at a fixed spot like a bedside table or kitchen counter for round-the-clock monitoring.

The Cair+ classifies CO2 above 1,000 ppm as Unhealthy — a level commonly reached in bedrooms with closed doors and windows at night, or in small living rooms with multiple occupants. At this point, the device flags poor ventilation, prompting you to open a window or turn on a fan. Levels above 1,500 ppm are marked Hazardous and are linked to headaches, drowsiness, and reduced concentration — something many households unknowingly experience without a monitor to identify the cause.

Yes. The device meets LEED v4.1, WELL Building Standard, WHO, and ASHRAE indoor air quality benchmarks — standards typically required in certified commercial buildings and hospitals. For home use, this means the pollutant thresholds are not arbitrary but based on globally recognized safe exposure limits. Prana Air has also published a correlation study comparing Cair+ readings against a BAM (Beta Attenuation Monitor) reference instrument, showing accuracy on par with professional-grade equipment.

The device is deployed across a wide range of reputed institutions — Delhivery (logistics), Wipro (IT), Canara Bank (banking and finance), Eros Hotel (hospitality), Hyderabad Eye Institute (healthcare), IISC Bangalore (scientific research), CEEW or Council on Energy, Environment and Water (policy research), and WHO or World Health Organization. The fact that a global health authority like WHO and a premier research institution like IISC Bangalore rely on the same monitor that is available for home use speaks directly to its accuracy and build quality.

Yes, and that is precisely what makes it well-suited for homes with elderly members, young children, or people with respiratory conditions. The Hyderabad Eye Institute deployed it to maintain strict standards in a clinical setting where any fluctuation in particulate matter or TVOC levels could affect patient recovery. For a home user, that same sensor sensitivity — covering PM1, PM2.5, PM10, HCHO, and TVOC — means you get clinical-level awareness of what your family is breathing every day.

Large offices with central air conditioning and high occupancy face CO2 buildup, chemical off-gassing from furniture and carpets, and recirculated particulate matter — all of which affect employee focus and productivity. Wipro and Canara Bank use the Cair+ to track these parameters continuously across their floors. For a homeowner, the same logic applies: if your home has limited ventilation, multiple occupants, or recently purchased furniture, the device helps you identify invisible problems before they affect your family's health or sleep.

Yes. IISC Bangalore (Indian Institute of Science) and CEEW (Council on Energy, Environment and Water) both operate in environments where data integrity is non-negotiable. Their choice to use this monitor reflects that it meets benchmarks required for scientific and policy work. The published BAM correlation data further validates this. For a home user, it means the CO2, HCHO, and particulate readings on your screen are not rough estimates but measurements that hold up under institutional scrutiny.

Hotel rooms and home bedrooms share the same challenges — enclosed space, limited fresh air exchange, off-gassing from furniture and bedding, and CO2 accumulation during sleep. Eros Hotel uses the monitor to ensure guest room conditions meet hospitality comfort standards. For a homeowner, placing it in a bedroom gives you the same oversight — knowing whether CO2 has crossed 1,000 ppm overnight, whether humidity levels are creating mold risk, and whether TVOC from room furnishings is within safe limits while your family sleeps.
