Air Pollution: Monitoring Methods For A Cleaner Tomorrow

Air pollution is a pressing issue, with the UK ranked among the worst polluters in Europe for airborne particles and nitrogen dioxide. With air pollution contributing to thousands of premature deaths each year, it is important to be aware of the air quality in your area. There are several ways to check air pollution levels, from using online tools and air quality monitors to hiring professionals to test the air quality in your home or local area.

Use an air quality monitor at home

There are a variety of air quality monitors available on the market that can help you check for air pollution in your home. These devices typically check for PM2.5 levels (tiny dust particles and other allergens in the air that you inhale), VOCs (volatile organic compounds like chemical pollutants), temperature, and humidity (for mould). Some of the more reliable air quality monitors include Foobot, Awair, Speck, and Air Mentor 6 in 1, which typically cost between $150 and $250.

If you're looking for a more affordable option, the Govee Smart Air Quality Monitor is available for under $40 and has an easy-to-use and pair app that can be further paired with Govee air purifiers. It also has an easy-to-read screen that displays PM2.5 levels, temperature, and humidity. Another affordable option is Ikea's Vindstyrka, which is available for under $50 and can be used on its own or paired with Ikea's Starkvind air purifier or its Home smart app via the Dirigera hub.

For those looking for a more powerful monitor, the AirGradient ONE air quality monitor can be integrated into various smart home networks with some technical know-how. It connects to WiFi and uploads its data to a web dashboard, which can be accessed from anywhere with an internet connection. The device also has a small OLED screen that provides updates on pollutants in your home or office, as well as a row of LEDs that show particle or CO2 levels based on user-adjustable thresholds.

It's important to note that some low-cost consumer air quality monitors may be less accurate and not easily calibrated, so it's worth considering your needs and budget when choosing a monitor. In addition to using a monitor, you can also improve your home's air quality by closing windows and doors, running an air purifier, and installing medium-MERV HVAC filters.

Check for mould

Mould is a fungus that can cause health issues such as allergies and respiratory problems. It is often invisible to the naked eye and can grow unnoticed, spreading until signs become obvious. It thrives in damp, dark, and humid environments and can grow on various surfaces, including walls, ceilings, floors, and even behind walls or under floors.

Visual Inspection

Begin with a visual inspection, especially in areas prone to retaining moisture and humidity, such as basements, bathrooms, and kitchens. Check corners, windows, and areas around pipes for any visible signs of mould, such as discoloured patches on walls, ceilings, or floors. Mould can appear as black, blue, white, brown, green or grey patches and might show up as spots or streaks.

Odour Detection

Mould has a damp, musty smell, similar to the odour of an old book. While smell is not always a reliable indicator of mould, a persistent musty odour, even after airing out rooms, could suggest a hidden mould problem.

Health Symptoms

In addition to visual and smell tests, consider any health symptoms you or other occupants may be experiencing. Mould exposure can lead to respiratory issues, allergies, and other health problems. If you notice an increase in respiratory symptoms or allergies, it could indicate the presence of mould.

External Factors

Inspect the exterior of your house for any signs of water entry points, damaged siding, or compromised seals. External factors such as leaks from heavy rain, flooding, or standing water can contribute to mould growth inside your home.

Mould Test Kits

If you suspect mould growth, you can use a mould test kit, which allows you to collect samples from various surfaces to determine the presence and severity of mould. Follow the instructions provided with the kit to ensure accurate results.

Preventative Measures

To prevent mould growth, maintain proper ventilation, especially in bathrooms and kitchens. Control humidity levels, promptly address any leaks or water damage, and remove standing water. Using mould-inhibiting paints, air conditioners, and dehumidifiers can also help inhibit mould growth.

Remember, if you suspect mould growth, it is important to address it promptly to prevent potential health risks and structural damage to your property.

Check air quality levels online, by phone or teletext

There are several ways to check air quality levels, including online, by phone, or by teletext. Many online tools provide real-time air quality data for locations worldwide. For example, the World Air Quality Index (WAQI) project provides a real-time air pollution map for over 80 countries, utilizing data from the worldwide EPA (Environmental Protection Agencies). The WAQI map is based on the latest US EPA standard and uses the Instant Cast reporting formula. The GAIA air quality monitor, featured on the WAQI website, measures PM2.5 and PM10 particle pollution, which is among the most harmful air pollutants.

Another online resource is AirNow.gov, which provides interactive maps of current and forecast air quality data for the United States and other locations. The Air Quality Index (AQI) Basics section of the website offers information on understanding and interpreting air quality data. AirNow.gov also offers a mobile app, EnviroFlash emails, air sensors, web cameras, and customizable maps to help users access air quality information.

In addition to online resources, some organizations may provide air quality information by phone or teletext. For example, AirNow.gov offers EnviroFlash emails and Air Sensors as part of its suite of services. Users can likely also find air quality information by calling local government offices or environmental organizations, although this may vary depending on the location.

Use a real-time air pollution map

There are many ways to check air pollution, one of which is by using a real-time air pollution map. These maps are available online and can provide you with a comprehensive overview of the air quality in your area, as well as in other regions around the world.

One such map is the AirNow Interactive Map, which offers air quality data for locations in the U.S., Canada, and Mexico. The map includes a time slider that allows you to view the NowCast AQI data for the last 24 hours. You can use the pause button to stop at any hour and review the data for separate pollutants, including Ozone, PM2.5, and PM10. The AirNow map also provides forecast information, with tomorrow's forecast available by 4 pm local time.

Another example is the World Air Quality Index (WAQI) map, which displays real-time air quality data for over 10,000 stations in more than 80 countries. This map uses the Air Quality Index (AQI) to provide information on various pollutants, including PM2.5, PM10, Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), and Carbon Monoxide (CO) emissions. By hovering over the flags on the map, you can access historical data and detailed information for specific cities.

In addition to these maps, there are other online resources, such as IQAir, which provide live air quality data and information on different types of air pollutants, including natural and man-made sources.

Hire a professional to test air quality

If you are experiencing symptoms of poor air quality, such as allergies, dizziness, rashes, fever, or fatigue, or if you are buying or selling a home, it is a good idea to hire a professional to test the air quality. A professional will be able to conduct more accurate tests and provide informed recommendations.

When hiring a professional to test air quality, it is important to look for someone with experience and expertise in the field. You can ask your realtor, lender, or home inspector for recommendations. It is also a good idea to research online reviews from customers who have used similar services in your area. Look for professionals with certifications from organizations such as the Indoor Air Quality Association or the International Association of Certified Indoor Air Consultants.

The cost of hiring a professional can vary depending on the company and the specific services required. Some companies offer cost-effective packages that cover common air quality concerns, while others charge by the hour or project. The average cost of air duct cleaning, for example, is around $380, but prices can range from $270 to $500 or more depending on various factors.

A professional air quality inspection typically involves taking samples from inside and outside the home to test for pollutants, allergens, and mould spores. These samples are then sent to a laboratory for analysis. The outdoor sample serves as a control to compare with the indoor results. Professionals use specialized equipment and have the necessary certifications to accurately test for a range of contaminants, including radon, mould, and lead.

Hiring a professional to test air quality can provide peace of mind and ensure that your home or workplace has safe and healthy air to breathe. It is an important step, especially when dealing with potential health risks or making significant financial decisions, such as buying or selling a property.
