How to Test Air Quality in the Summer Months

As summer brings with it warmer temperatures and outdoor activities, it's more important than ever to ensure that the air you breathe indoors is of good quality. To protect yourself and your loved ones from pollutants and allergens, it's useful to regularly test the air quality in your home during the summer months. In this blog, we'll explore effective methods to test and improve air through innovative solutions for maintaining healthy indoor environments.

Why Is It Important to Monitor Air Quality in the Summer?

Understanding the impact of air quality on health is essential. Poor air quality can contribute to respiratory problems, trigger asthma attacks, worsen allergies and even have long-term health implications. Monitoring air quality in the summer specifically is vital for several reasons. 

1. Spikes in Temperature

Summer months often bring higher temperatures, leading to the increased use of air conditioning and reduced ventilation. This can result in the accumulation of indoor pollutants, including allergens, volatile organic compounds (VOCs), and particulate matter, which can negatively impact respiratory health. By monitoring air quality, you can identify and address these issues promptly, ensuring a healthy indoor environment.

2. Increase in Pollutants

During the summer, outdoor activities such as gardening, barbecuing, and construction projects can release pollutants into the air. These pollutants, including dust, smoke, and chemical fumes, can easily find their way indoors when we keep our windows and doors open, quickly compromising indoor air quality. Regular monitoring of your air quality allows you to detect such pollutants and take appropriate measures to reduce their presence.

3. Rise in Allergies

individuals with allergies or respiratory conditions may experience heightened symptoms during the summer due to increased pollen and mold spore levels. Monitoring air quality helps identify specific allergens and allows for targeted interventions, such as using air purifiers or adjusting ventilation systems, to alleviate symptoms and improve overall well-being.

Tools and Instruments for Air Quality Monitoring

Fortunately, a range of tools and instruments are available to monitor air quality effectively. Understanding the functionalities of each can help you as you select the most suitable monitoring solution for your needs.

Portable air quality monitors are often used to measure air quality in homes and buildings. These compact devices are designed for personal use and provide real-time measurements of key air pollutants. Portable monitors typically measure parameters such as particulate matter (PM), volatile organic compounds (VOCs), carbon dioxide (CO2), temperature, and humidity. They are convenient for assessing air quality both indoors and outdoors. 

With Coway, you get the benefits of a monitor and purifier all in one. Every model of the Airmega air purifier allows you to easily monitor the condition of the air in your home in real-time. Certain purifiers, including the Airmega 300S and Airmega 400S, are equipped with a brightly colored LED indicator ring that allows for real-time monitoring of your air quality index (AQI). assess the air quality status in your home. Other models leverage LED light designs to update you on your air quality.

For the Wi-Fi-enabled Airmega models, Coway also offers the IoCare app, which allows you to monitor indoor air quality and filter status directly from your phone. Through the app, you can set the unit timer, receive real-time updates on air quality and even control the air purifier remotely. The app also enables you to track a room's air quality over time and provides information on outdoor air pollution levels for cities in your area, helping you determine the best times to venture outside.

How to Identify Key Air Quality Indicators

To comprehensively monitor air quality, it's crucial to be aware of a few key indicators. Identifying these indicators involves monitoring various parameters that can indicate the quality of the air in a given area. 

Here are some common indicators to consider:

Particulate Matter (PM): PM refers to tiny solid or liquid particles suspended in the air. PM2.5 and PM10 are the most commonly measured sizes. High levels of PM can contribute to respiratory problems and reduced visibility. Monitoring PM levels is crucial in assessing air quality.

Carbon Monoxide (CO): CO is a colorless and odorless gas produced by incomplete combustion of fossil fuels. It can be emitted by vehicles, heating systems, and industrial processes. Monitoring CO levels is important as high concentrations can be harmful, particularly in enclosed spaces.

Volatile Organic Compounds (VOCs): VOCs are a group of organic chemicals that can be released by various sources, including solvents, paints, and cleaning products. Some VOCs are harmful to human health and contribute to the formation of ground-level ozone. Monitoring VOC levels helps evaluate air quality indoors and in urban areas.

Temperature and Humidity: These parameters can affect the dispersion and concentration of pollutants in the air. Higher temperatures and low humidity can exacerbate air pollution, especially for certain pollutants like ozone and particulate matter.

How to Test Air Quality

To effectively test air quality, it is important to follow a systematic approach. If you’re concerned about air quality outside, particularly in the height of fire season, conduct research to identify local air quality resources, such as agencies, organizations, and online platforms that provide reliable data. 

Once you have the necessary equipment, it is useful to determine the locations where you will monitor air quality regularly around your home or building. We advise selecting spots near potential pollution sources or areas of concern, like your stove.

After collecting air quality data, it's important to interpret and understand the information effectively. This involves familiarizing yourself with the Air Quality Index (AQI), a commonly used indicator that provides a standardized assessment of air quality. 

One of the simplest methods to test air quality is by using an air quality monitor. Coway offers a range of advanced air quality monitors that can measure various parameters like particulate matter (PM2.5 and PM10), carbon dioxide (CO2) levels, volatile organic compounds (VOCs), and more. These monitors provide real-time data and alerts, allowing you to stay informed about the air quality in your home. Coway makes it easy to understand the quality of air in your space by using a color system. Depending on the model, different colored LED indicator lights will represent air quality levels.

To test for specific contaminants, you can also employ additional methods. For instance, if you suspect mold growth, you can use a mold testing kit, which typically involves collecting air or surface samples to be analyzed in a laboratory. Similarly, for VOCs, you can employ specialized VOC testing kits to identify and measure the presence of these harmful chemicals.

5The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
