How to measure indoor air pollution

Measuring indoor air pollution levels is very important, especially for people living in cities or areas with poor air quality. Understanding the quality of indoor air can help us take steps to improve it and protect the health of ourselves and our families. Here are some commonly used methods to measure indoor air pollution levels:

How to measure indoor air pollution

1. Detect common indoor pollutants

Indoor air pollutants include volatile organic compounds (VOCs), particulate matter, formaldehyde, carbon dioxide, nitrogen oxides, etc. You can measure the concentration of these pollutants by using a professional indoor air quality testing instrument, such as a multifunctional indoor air quality monitor or a specific pollutant detector. These instruments typically feature a Multi-In-One Sensor Module or a single sensor and display that can provide real-time data and alert you to potential health risks.

2. Measure air circulation and humidity

In addition to pollutant concentration, air circulation and humidity are also critical to indoor air quality. Poor air circulation can cause air pollutants to become trapped in indoor spaces, increasing the risk of exposure. You can use an anemometer to measure air velocity and make sure the air is flowing properly. In addition, the humidity also needs to be controlled within an appropriate range. Too high humidity can lead to mold growth, while too low humidity can cause respiratory discomfort. You can use a hygrometer to monitor indoor humidity levels.

3. Observe and record

In addition to using instruments for measurement, observing and recording the indoor environment are also important methods. Pay attention to the presence of odors, pungent odors, or other unusual odors. Documenting these observations, along with any health-related symptoms, can help you work with a professional to analyze and resolve potential indoor air quality issues.

How to improve indoor air quality

1. Fresh air system

If the indoor air is not good, you can install a fresh air system. The fresh air system can filter the fresh outdoor air and pass it indoors, so that the indoor air can be kept fresh at all times. The current fresh air system can also be installed on the surface.

2. Green plants

Some green plants can be cultivated indoors, such as spider plants, pothos, etc., which can not only decorate the indoor environment, but the branches and leaves of the plants can also absorb dust or harmful gases, and even adjust the air humidity for users. However, it should be noted that plants rely on photosynthesis. When there is sunlight during the day, they can create fresh air indoors, but at night, they emit carbon dioxide just like people. Over-cultivating will cause excessive carbon dioxide levels at night.

3. Open windows for ventilation

Regularly opening windows for ventilation is one of the effective ways to improve indoor air quality. Through ventilation, indoor pollutants can be discharged and the air can be kept fresh.

4. Use an air purifier

There are many types of air purifiers on the market, but most of them have similar working technologies and principles. They mainly adsorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odors) through the filters in the purifier. , decoration pollution such as formaldehyde, bacteria, allergens, etc.), thereby effectively improving air cleanliness and providing a healthy breathing environment.
