Did you know that 9 in 10 homes suffer from at least one air quality issue, according to studies? While that seems like an astoundingly high number, it shouldn’t be surprising. From irritants like dust and pet dander to more harmful pollutants like radon and air pollution, you might be breathing in dirty air. An air quality monitor is a perfect way to help you breathe better, healthier air and test air quality, and most come with a free app for your mobile phone.

While most of our recommendations below are intended for indoor use only, outdoor air quality monitors can be equally useful for allergy sufferers. While options here aren’t as numerous, we could find a few options that we think are worthy of consideration.

PM stands for particulate matter, with the number the size measured in microns. Many air quality monitors detect particulate matter in two sizes, PM2.5 and PM10 (these fine particles can be as small as the diameter of a human hair!). Better air quality monitors can also measure PM1 and other pollutants such as VOCs (volatile organic compounds, commonly found in household cleaners and cleaning chemicals), CO2, carbon monoxide, and even radon.

While they may not be able to detect mold directly, some air quality monitors can alert you to conditions that might make mold growth more likely.

Who should purchase an air quality monitor?

Purchase an air quality monitor if you or a loved one in the home has allergies, asthma, or other respiratory problems. These devices will help them feel better by letting them know when indoor air quality is poor so they can take action to improve air quality. Also, homeowners that are concerned about their indoor air quality and common household pollutants should invest in one of these devices as well.

Can I get sick from poor air quality in my home?

Yes. Regardless of your health status, bad indoor air quality can make you sick. Acute exposure to high concentrations of particulate matter can cause difficulty breathing, throat and eye irritation, and chest pain. Prolonged exposure to bad air quality can cause the following symptoms:

  • Lung damage
  • Dry throat
  • Chronic bronchitis
  • Irregular heartbeat
  • Increased fatigue

Even if you are healthy and at a lower risk for contracting a respiratory illness, bad air quality can make you sick after prolonged exposure. Fine particulate matter (PM2.5) poses the greatest risk for potential health problems since these particles can enter the lungs and possibly the bloodstream. A good indoor air quality monitor is a worthwhile investment regardless of your health status.

We recently wrote a blog post on who should buy an air quality monitor, which if you are in one of the high-risk groups above, you should definitely read.

The Amazon Smart Air Quality Monitor is one of Amazon’s latest smart home gadgets. While you’ll have to have an Alexa product to use the device, it measures everything the above devices do at a fraction of the price. We’d strongly recommend this for anyone already in the Alexa ecosystem.

It’s brand new, so unfortunately we haven’t had the chance to review it yet. However, our experience with Amazon products has been mostly very positive. We’re excited to get one to try for ourselves, and will certainly report back ASAP.

The Best Outdoor Air Quality Monitors

Allergy sufferers and those with breathing difficulties might find an outdoor air quality monitor useful. These devices measure common outdoor pollutants, and in some cases, your data is shared publicly (with your consent) to help others around you determine air quality. Some outdoor air quality monitors can also be used indoors; however, we recommend you purchase an air quality monitor intended for indoor use. They typically measure pollutants found in the home that aren’t typically found outdoors.

Davis’ AirLink air quality monitor doesn’t measure carbon dioxide or VOCs but is one of the few monitors out there to detect PM1 particulate matter. PM1 is especially dangerous as it is small enough to penetrate the bloodstream even further and is difficult to disperse. While the AirLink can be used inside, we recommend one of our internal air quality monitors instead because they’re able to measure much more than just particulate matter. Do keep in mind that you need a WeatherLink Live access point to use the AirLink, which comes with either the Vantage Vue or Vantage Pro2 weather station.

Common Pollutants 101

Confused by some of the terms we used above? We’ve created this easy-to-follow guide below to help you understand what the various common pollutants are and how they might pose a risk to your overall health. For more information on pollutants, we suggest checking out the EPA’s website.

Particulate Matter (PM)

Particulate matter, or PM for short, is a mix of particles and droplets in the air. PM can come in various shapes and sizes, but anything less than 10 micrometers in diameter (PM10) is hazardous to your health as it can be inhaled. PM2.5 (2.5 microns in size) and PM1 are also commonly measured particulate matter sizes.

Extended exposure to particulate matter, especially PM1 and PM2.5, can cause issues with the eyes, nose, throat, and lungs. Symptoms of exposure are shortness of breath and allergy-like symptoms. If you have existing medical conditions like asthma and heart disease, you should be especially mindful of PM levels in the air.

Common outdoor sources of PM include vehicle exhaust, wildfires, and power plant emissions. Indoor sources such as cooking, burning fireplaces, and smoking can also produce PM as well.

Volatile Organic Compounds (VOCs)

VOCs can have both short and long-term health effects. While VOCs may be present indoors, concentrations can be as much as 10 times higher indoors, the EPA says. Common household products like hairspray, cosmetics, cleaning fluids, disinfectants, paints, and varnishes produce VOCs, such as burning wood and natural gas.

Formaldehyde is a common VOC and is found in many places in the home: many building materials, including plywood, glues, and insulation contain it, as well as drapes and furniture fabrics.

Short-term exposure to VOCs causes minor symptoms like throat irritation, nausea, and fatigue. Longer-term exposure can cause more severe respiratory issues and can damage the liver and kidneys. Typically VOCs are emitted in larger quantities when in use. However, products may emit smaller amounts of VOCs.

Carbon Monoxide

This odorless and invisible gas is already well known as a hazardous pollutant. At higher concentrations, it can cause loss of consciousness and even death — and many times, its victims don’t know they’re being poisoned. Even at lower levels, issues including confusion and memory loss can occur.

We strongly recommend that you do not depend on any air quality monitor to detect carbon monoxide. The best way to detect carbon monoxide is a carbon monoxide detector. Many higher-end smoke detectors offer this functionality.

Radon

The leading cause of cancer behind smoking in the United States, radon is a naturally occurring invisible colorless gas. It is the byproduct of the naturally occurring breakdown of uranium in soil, rocks, and water and can be found indoors and outdoors. Previously, a kit must be purchased to test for this, which takes about three months and must be shipped off to a lab.

The AirThings Wave Plus is currently the only air quality monitor that can test for radon in real-time.

Carbon Dioxide (CO2)

While not as hazardous as some of the other indoor pollutants, even at fairly high levels, concentrations of 1,000ppm or more can cause a decline in cognitive and decision-making performance in humans. Carbon dioxide is a natural byproduct of humans breathing, so in poor ventilation, these levels can easily get to levels of 1,000ppm or more in the home. Most indoor air quality sensors can measure CO2 levels in the air.

Temperature and Humidity

While not necessarily a pollutant, high temperatures, and humidity can cause mold and mildew growth, and some humans are sensitive to mold and mildew in the air, causing allergy-like symptoms.

Why You Should Buy an Air Quality Monitor

While not necessarily thought of like a weather instrument per se, weather can promote poor air quality. Think of a hot day with no wind. Air becomes stagnant, and pollution builds. We find air quality monitors extremely useful here at our setup — especially since we have several people in our household with medical issues that can be exacerbated by poor air quality.

If you have medical issues like this or are even just curious what the air quality is like in your home and outdoors, by all means, consider an air quality monitor. We’ve been thrilled with our Davis AirLink and use it to ensure we’re breathing clean, pollutant-free air whenever possible.
