Air Quality Monitor

Airborne contaminants can affect your breathing, mental acuity and overall health. But knowing about the air you breathe in your present environment can help you take the steps you need to remain healthy and become a better you. Honeywell’s innovatively designed, portable Air Quality Monitor enables you to do exactly that!

Featuring a highly responsive touchscreen, multiple colour indicators and built-in Wi-Fi connectivity, this award-winning device measures six different pollutants, allergens and parameters. Leveraging a proprietary algorithm, the touch display sensor provides an IQ percentage reading, a reliable measure of how well the human brain can work in the present environment. It also measures CO2, temperature, humidity, mould as well as pollutants from everyday products.

When coupled with its mobile phone app, the Air Quality Monitor can be used to check ambient air quality anytime, anywhere. Take steps to protect yourself and those you care about, with the Air Quality Monitor from the world leader in indoor air quality solutions!


Your health is at stake
A variety of pollutants, particulate matter, gases, chemicals and other substances in the air can affect our wellbeing – both physical and mental. Get insights into the air you’re breathing and take action to improve its quality.

For a full list of the parameters the Air Quality Monitor will show (and why it’s important to keep track of them), see below!




Particles in the air with a diameter of 0.1-2.5 micrometres. This is just 3% the diameter of a single strand of human hair. It can include soot, combustion by-products, fossil fuel smoke, cigarette smoke, dust, allergens like pollen and mould, etc.


PM2.5 irritants may lodge in the lungs causing asthma, respiratory inflammation, aggravated allergies, or lung and heart conditions. They may become carcinogenic after long-term exposure, increasing mortality risk.




Colourless, flammable and strong-smelling gas released into the air by off-gassing or out-gassing of pressed wood, particle wood and plywood products, wall insulation, new furniture, glue, adhesive products, etc.


May cause watery eyes, burning sensation in the eyes, nose, and throat, coughing, wheezing, nausea or skin irritation. HCHO has also been recognised as a probable human carcinogen.




Emitted by a wide array of household products including paints and varnishes, cleaning and disinfecting products and cosmetics. Concentrations are consistently higher indoors (up to 10 times) than outdoors.


May cause eye, nose and throat irritation, headaches, loss of coordination, nausea and damage to the liver, kidney and central nervous system. It is a potential source of cancer and may have other unknown short-term and long-term adverse effects.




Colourless and odourless gas produced by burning carbon and organic compounds, and as a by-product of respiration. The main cause of CO2 build-up is poor ventilation.


High levels may cause lack of concentration, dizziness, headache, visual and hearing dysfunction, and even unconsciousness.




Water vapours suspended in the air.


Increased levels may cause excessive mould, fungus and bacteria to grow. Decreased levels may cause skin problems, breathing issues, itchy eyes, and may cause/aggravate allergic reactions.




Honeywell’s proprietary algorithm can determine the percentage of IQ being used by a person, depending on the quality of air they’re breathing. This varies depending on environmental factors directly impacted by CO2, TVOC and PM2.5 levels. Excellent air environment can have a positive effect on focus, concentration and memory, and raise overall cognitive ability.


Lower IQ% level may indicate an environment that does not support good cognitive performance.

Frequently Asked Questions
Browse through our FAQs if you need further information on the Honeywell Air Quality Monitor.



Is indoor air quality a problem?
Yes it is. Poor indoor air quality impacts us all. The U.S. Environmental Protection Agency estimates that indoor air can have 2 - 5 times as many pollutants as outdoor air, which means that we spend a majority of our time being bombarded by contaminants.


What do you measure, and why do you measure it?
We measure the following pollutants and allergens because they are common, and can be drastic in their effects on health in concentrations if left unchecked:
PARTICULATE MATTER (PM2.5) asthma, respiratory inflammation, aggravated allergies, lung and heart conditions, carcinogenic after long-term exposure
FORMALDEHYDE (HCHO) may cause watery eyes; burning sensations in the eyes, nose, and throat; coughing; wheezing; nausea; skin irritation
TOTAL VOLATILE ORGANIC COMPOUNDS (TVOC) may cause eye, nose, and throat irritation; headaches; loss of coordination and nausea; damage to liver, kidney, and central nervous system
CARBON DIOXIDE (CO2) may cause lack of concentration; memory loss; depression; dizziness; headache; visual and hearing dysfunction;
HUMIDITY skin problems; breathing issues; itchy eyes and allergic reactions
IQ% Indicates the percentage of your total IQ available for use in your environment. Indicates the potential for poor performance of advanced cognitive functions related to one or more of the other measurements. Good indication that one of the other measurements are less than optimal.


Who is this device designed for?
The device is designed for everyone who cares about the air they breathe. Whether you’re a busy professional, a parent or a manager – the Air Quality Monitor can help you make better sense of your surroundings.



What is the IQ%?
Environmental factors such as high CO2 levels, volatile organic compounds and particulate matter affect people’s cognitive abilities. IQ% provides a numerical output correlating to the score you would get if you were to give an IQ test in your current environment.


How long to fully charge the battery right out of the box/initial charge?
6 hours


How long does every subsequent charge take?
6 hours


How long does the device run on a full charge/ what is the battery capacity?
After charging is completed, Normal mode: 14 hours, Sleep mode: 40hours. Battery capacity: 2600 mAh.


Why is one of the on-screen symbols blinking?
The levels of that pollutant may have reached elevated levels. Clicking on the symbol will provide a number readout and the arc light at the top will go red as a warning.


Can individualized alarm thresholds be set for the device?
Yes! Setting the menu can set the alarm. Thresholds for the device set as follows:


When and why do I calibrate the HAQ.
To combat drift, the HAQ CO2 sensor should be occasionally calibrated, which involves exposing it to a known gas source. It takes multiple readings, calculates an average, stores the difference in memory as an offset that is then automatically adjusted against subsequent readings.


What are the steps to recalibrate the device?
In the outdoor environment, switch to the CO2 interface, press and hold the middle position of the screen for 3 seconds. The calibration prompt appears. After 10-15 minutes when the calibration prompt disappears, the calibration is complete.


What is the optimum placement of the device?
Ideally, the device should be close to where you are but not near doors or windows. The latter might give different readings as the air might not have dissipated homogeneously through the room. For best results, use one device for 1000 – 1500 sq ft of air or for one room in a house.


Can I use this in my car?
As long as your battery is charged or as long as you have a connection for a USB cable, yes you can. An internet connection is required for data logging. You can use your phone as a hotspot or the device as a standalone monitor.


Can I use this outdoors in my balcony/ garden/ patio/ yard?
Yes, again, as long as you have a sufficiently charged battery and/or a socket. Note: outdoor readings will be remarkably different from indoor readings.



What version Android smartphone do I need to run the app?
Version 4.4 or later is later. The Google Store won't download the app unless it is compatible with your smartphone.


Can multiple devices be connected to the same app?
Yes. You can place multiple devices around your home or a loved one’s home that will connect to the app on your phone. Follow the directions on the app to connect multiple devices.


Can the same device’s data be read on multiple mobile phones?
Yes, just use the same username and password on the additional mobile phones.



Can I view data from a computer (in addition to app)?


Where is the data collected and stored?
All device data is stored securely in the Honeywell cloud. The app shows trending data for one day or one month.


How often is the device data uploaded to the cloud?
The device checks in with the cloud once every minute. In energy-saving mode this frequency drops to once an hour.


How long does the data stay in the cloud?
Raw data for 7 days, hourly average for 1 month, daily average for 1 year. But the last day and last month are viewable in the app. If you are a business that is looking for more insights, please contact us directly.


Does the device store data in case of connectivity loss?
No, the device does not have its own memory storage.



Is there an API for enterprise customers?
Not yet but we are working on developing an API that enables businesses to pull data from our cloud. For more details, contact us directly.
