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. It runs on a 1600 mAh battery for up to 3 hours on a single charge, which means you can also unplug it and carry it from room to room, to find out which part of your home has the worst pollution.

The device has a dedicated Ventilation Score as part of its AI Health Index, rated 0 to 10. It works out this score from the CO2 level in your room. When CO2 crosses 800 ppm (Moderate range), it signals that the fresh air supply is too low. For context, a well-ventilated living room usually stays below 600 ppm. The score gives you a clear, simple number to act on, so you do not have to read raw ppm values yourself.

Yes, and this is one of its most practical uses for homes. The monitor has an electrochemical sensor just for HCHO (formaldehyde). This gas is given off by new wooden furniture, MDF boards, wall paints and the adhesives used in renovation. Levels above 0.1 mg/m³ are classed as Unhealthy, and above 0.35 mg/m³ as Hazardous. Place it in a newly furnished room or a space you have just renovated, and it will tell you when the room is safe to use again.

No. The Cair+ connects to your home Wi-Fi and sends all data to the AQI mobile app, which runs 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 past data for up to several months, so you can spot patterns, such as your bedroom CO2 rising every night because the windows are closed.

Yes. The AQI app and TV app linked to the Cair+ show your indoor readings side by side with outdoor AQI data from the AQI monitoring network. If outdoor PM2.5 is higher than indoors, as is common during Delhi winters or dusty days, the data will tell you to keep the windows closed and run a purifier instead.

Yes. The device includes a Filtration Score in its AI Health Index, which reflects how well the purifier works in the room. Beyond this score, you can track particulate matter levels before and after you turn your purifier on. The Historic Graph screen shows the drop in pollutant levels over time, which gives you direct evidence of whether your purifier is making a real difference.

The monitor is designed with the look of your home in mind. It comes in an ivory finish with a color LED display that offers five screen modes. One of them is a Clock/Screensaver mode, which turns the device into a digital clock that shows the AQI, so it doubles as a home display piece rather than looking like industrial equipment. It blends in well in a living room, bedroom or on a study desk.

It charges via a standard Type-C USB cable, the same one used by most Android phones and laptops, so you do not need a separate or special charger. The 1600 mAh battery lasts up to 3 hours on its own, but the device can also run non-stop while plugged in, which makes it ideal to keep in a fixed spot, like a bedside table or kitchen counter, for round-the-clock monitoring.

The Cair+ classes CO2 above 1,000 ppm as Unhealthy. Bedrooms often reach this level at night with the doors and windows closed, as do small living rooms with several people inside. At this point, the device flags poor ventilation and prompts 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 poor concentration. Many households experience this without knowing, as they have no monitor to find the cause.

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

The device is in use at many well-known institutions, including 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. A global health authority like WHO and a top research institute like IISC Bangalore rely on the same monitor that you can buy for your home. That speaks directly to its accuracy and build quality.

Yes, and that is exactly what makes it a good fit for homes with elderly members, young children or people with breathing conditions. The Hyderabad Eye Institute installed it to keep strict standards in a clinical setting, where any change 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 insight into what your family breathes every day.

Large offices with central air conditioning and many people face CO2 buildup, chemical off-gassing from furniture and carpets, and particulate matter that keeps recirculating. All of these affect how well staff focus and work. Wipro and Canara Bank use the Cair+ to track these parameters non-stop across their floors. For a homeowner, the same logic applies: if your home has limited ventilation, several occupants or newly bought furniture, the device helps you spot unseen 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 work in settings where data integrity is non-negotiable. Their choice of this monitor shows that it meets the benchmarks needed for scientific and policy work. The published BAM correlation data backs this up further. For a home user, it means the CO2, HCHO and particulate readings on your screen are not rough estimates, but measurements that stand up to institutional scrutiny.

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