Three Steps to Screen or Estimate Indoor Air Quality
Today, people are more and more concerned about indoor air quality (IAQ). However, they don’t spend much time on air quality inspection, which is an essential step. They usually use simple ways to cover indoor air quality issues, but these are ineffective. Luckily, a properly conducted IAQ quiz helps to analyze the primary causes of indoor air pollution. What’s more, an effective IAQ screening allows you to make comprehensive strategies to resolve air quality issues in a long-term plan.
Before conducting a good IAQ screening, it’s necessary for you to prepare the right tools, which are easy to get, and to find a laboratory that can test your samples. When this has been done, three steps will help you to find contributing risk factors of indoor air pollution and to remove these causes to improve the air quality. Following are the most common tools used in an IAQ estimate:
- Swab testing kit
- Air-o-cell kit and sampler machine
- Petri Dish Test Kit
- VOC sampling tool
Step one: outline a proper visual checklist
A visual checklist helps you to identify the causal factors of your home air quality. Generally, some visible signs are helpful to evaluate the air quality. For example, whether the ventilation system is clean or not, and whether there are molds or spores in rooms are typical questions. Also, these questions offer you a context for air pollution evaluation. Questions listed below can give you ideas for your own checklist.
- Do your family members suffer from irritation or respiratory problems?
- Do you raise pets in your home? If so, how many pets do you have?
- Does your home have circulating air brought by your ventilation system?
- Are any members in your family smoking?
- Is the ventilation system dirty or clean?
- Do you use any air fresh appliances in recent days? Such as an air purifier or what?
- Is there any mildew in your home, especially in corners or basements?
- Does your home smell fresh or some smell of odor?
Step two: use tools to test the air quality in your home
You can either invite an expert to do the test or just conduct it yourself. An expert usually uses a simple kit to test the samples, and then takes it to his lab for a test report, which gives a clear indication of air pollution issues in your home. But the expert may sell you additional services or solutions by helping you analyze the test report. It will certainly increase your expenses. On the other hand, conducting the IAQ test yourself is economical and convenient. All the air pollutant test kits can be bought from websites, such as volatile organic compound (VOC), formaldehyde, radon, allergen test kit and others. You can use the test kit, which is similar to what the expert uses, to inspect the air quality in your home, and send it to a lab where levels of air pollutants will be determined. Finally, you can receive the report sent by the lab, and it will tell you the air quality, levels of air pollution and available solutions to your problems. If you think the problems exceed your ability to deal with them, an expert is always there for you.
Step three: use lab data to solve problems
The lab report often points out all the pollutants in your home in detail and indicates the main causes of air pollution, and whether they are particulates, bacteria, mold or toxic gas, among others. When you are analyzing the test report, don’t forget your checklist, which will help you to interpret the data. After finishing the assessment, you can take prompt and effective action to remove the air pollutants and create high-quality indoor air. Everyone should develop an awareness about improving indoor air quality, especially in a time when air pollution is a global issue. Good indoor air quality is always good for your health.
