The most professional air quality monitor, indoor portable air quality detector, carbon dioxide meter
- Air quality is important for anyone and for the home. Especially for people with allergic rhinitis, asthma, infants and the elderly the air quality requirements are even higher. According to the EPA report there are 188 Harmful air pollutants in the air around us. This is why it is essential to have a professional, accurate air quality meter and pollution analyser. This allows us to know the air environment in our homes in real time.
Before we can recommend the most professional air quality tester, we need to know more about air quality.
What indoor air pollutants include and where they come from？
Indoor air pollutants include:
- Ozone (O3)
- Carbon dioxide (CO₂)
- Carbon monoxide (CO)
- Sulphur monoxide (SOx)
- Sulphur dioxide (SO2)
PM: PM stands for “particulate matter” and measurements of it are able to tell you how many liquid or solid particles of varying sizes are in your air. The particles are measured in microns, given after the “PM.” For example, PM2.5 tests for the amount of particles that are approximately 2.5 microns in your air.
AQI: This stands for Air Quality Index and is a popular, but somewhat outdated, method for measuring air quality. Essentially, the AQI measures pollutant levels for a wide variety of substances, gives them each a score from 0-500, and reports the highest one. It doesn’t matter if only one pollutant is high or if several are, only the top one is getting reported. Still, the data is historically known and the conversions for each pollutant can still be useful. If you want to play around with the system, a handy AQI calculator is available for you.
VOCs: These are “Volatile Organic Compounds” and largely come from human sources. The EPA warns that sources of these contaminants include household cleaners, building materials, and standard office equipment. They also have found that these pollutants are consistently found in much higher concentrations in indoor settings.
Source of pollutants：
The main sources of air pollutants are car exhaust, chemical plant emissions, renovation materials, kitchen fumes, cigarette smoke, etc.
How can I purify the air and improve its quality?
- Air purifiers can be installed in your home. They can effectively improve the air in our homes.
- Open windows and doors frequently to increase the rate of air convection (15 minutes of ventilation in half an hour to an hour is recommended). This is also the most effective and economical way to improve air quality.
- Keeping some green plants in your home, they improve the ambience of our environment while also photosynthesising and releasing more oxygen.
Air Quality Index Rating
EPA they provide a very comprehensive explanation of air quality.
Each category corresponds to a different level of health concern. The six levels of health concern and what they mean are:
- “Good” AQI is 0 – 50. Air quality is considered satisfactory, and air pollution poses little or no risk.
- “Moderate” AQI is 51 – 100. Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people. For example, people who are unusually sensitive to ozone may experience respiratory symptoms.
- “Unhealthy for Sensitive Groups” AQI is 101 – 150. Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
- “Unhealthy” AQI is 151 – 200. Everyone may begin to experience some adverse health effects, and members of the sensitive groups may experience more serious effects.
- “Very Unhealthy” AQI is 201 – 300. This would trigger a health alert signifying that everyone may experience more serious health effects.
- “Hazardous” AQI greater than 300. This would trigger health warnings of emergency conditions. The entire population is more likely to be affected.
How to choose the best air quality monitor?
A few notes before we jump in.
- Indoor air quality monitors typically test airborne particles and some volatile organic compounds in a localized area. Most monitors don’t test for carbon monoxide or radon, though. If you have old gas appliances or other reasons for concern over carbon monoxide, install a monitor ASAP. This gas can be deadly. As for radon, check the EPA’s guide to radon to determine the risk in your area (and what to do about it).
- Choose a monitor that has a good reputation for detecting the kinds of indoor air pollutants you suspect are an issue in your home. Just as with an air filter, there’s little point paying a lot to test for or filter tobacco smoke if you’re a non-smoker, or for mold if you live somewhere extremely dry. Some monitors can accurately measure smaller particulate matter that can enter the lungs (around PM2.5), or PM1, which is strongly associated with cardiovascular disease risk. Most monitors aren’t this sensitive, so if it matters to you, check the specifications carefully.
- The EPA has studied indoor air quality monitors rather extensively and is quite scathing about their accuracy, especially over time. A 2019 report strongly suggests that these low-cost sensors tend to become less effective at detecting VOCs after six months. Unlike with other products, we don’t, therefore, recommend borrowing an older monitor. In fact…
- Because indoor air quality monitors are limited in their usefulness, you don’t necessarily need to buy one at all! Instead, check outdoor air pollution levels through the EPA app and keep doors and windows closed on particularly bad days.
- Finally, even if your monitor tells you everything is normal but you still suspect something amiss with the air in your home, follow your hunch and take the above steps to improve things.

Q: Can an air quality monitor detect mold?
An air quality monitor can be a mold detector but won’t be able to tell you that you have mold. Molds are typically detected by PM10 sensors, but so are other particulate matters, like pollen. So, an air quality monitor that can test for PM10 particles will be able to detect mold particles in your air but not tell you that those particles are mold.
