Although pollution is often thought of as outdoor air pollution, indoor air pollution is also. In fact, according to the World Health Organization, over 4 million people die each year from exposure to indoor air pollutants. One source of indoor air pollution is dust. Dust can contain various particles that can be harmful to your health, such as lead, asbestos, and mold.
So how do you measure the amount of dust in the air? In this blog post, we will discuss how to measure dust in the air with different methods for measuring dust in the air. So stay safe and healthy by keeping an eye on the dust levels in your environment!
Why Measure Dust in The Air?
There are a few reasons why measuring dust in the air is essential. First, as we mentioned earlier, dust can contain harmful particles that can be dangerous to your health. By measuring the amount of dust in the air, you can ensure that the levels are safe and within guidelines set by agencies like the EPA. Second, measuring dust in the air can help you identify and fix sources of indoor air pollution.
If you know how much dust is in the air, you can better understand how much pollution comes from different sources in your home or office. Finally, measuring dust in the air can help you track your cleaning efforts’ effectiveness! By monitoring how much dust is reduced over time, you can ensure that your cleaning routine is effective.
Things You’ll Need
To measure dust in the air, you will need a few materials:
- A dust mask or respirator to protect your lungs from particles in the air.
- A vacuum cleaner with a high-efficiency particulate air (HEPA) filter to remove particles from the air.
- A measuring device such as a tape measure or an air quality monitor to measure the amount of dust in the air.
A Stepwise Guide on How to Measure Dust in The Air
Step 1: Find Out How Much of Dust is in the Air
Before you can begin measuring how much dust is present in your air, you must know how much dust there is. Depending on the dusty it is, you will have to choose the best tool for this job. There are two methods of finding out how much dust there is:
The first method is scientists do it, which involves using an optical particle counter device.
- This type of fog counter is not exactly easy to find since it costs around four thousand dollars.
- The second method is the more curious people do it. This requires some elementary tools that are usually available at home or can be found somewhere in your local hardware store. You will need spray bottles, baking soda and vinegar, a stopwatch, a ruler, and a dust bin with a fine mesh top for this DIY.
Measurement Using Spray Bottles & Baking Soda & Vinegar Method Procedure:
- Fill up the spray bottle with water without spraying any drops out of it by squeezing hard on the bottle’s trigger. Then, spray a quick burst of water into the air.
- Sprinkle some baking soda on top of the spray pattern that you sprayed into the air. Cover as much area as possible, but make sure it is not excessively crowded because there has to be enough space for you to put a drop of vinegar on top of the baking soda without touching any part of it.
- Put a small drop of vinegar onto the surface and watch how it fizzes up within seconds due to the reaction with baking soda.
- Rinse your dust bin with cold water and empty it as quickly as possible to gain as many droplets from inside before they disappear or break down from evaporation. You will also need a stopwatch to measure how many seconds it takes for the fog pattern to dissolve.
- Count how many droplets you got in twenty seconds and how many droplets would be there if there was no dust on top of the baking soda and compare how much more of them go into solution (dissolve) due to cloud droplets. For accurate results, make sure that all surfaces around the area are still and dry because the wind may cause some inaccuracy in your test.
Record how long it takes for your sample of air to dissipate completely. This will be how much time is required for the speed of light to travel one meter or how long it takes for one centimeter’s worth of distance covered by light.
Step 2: Decide How Big a Dust Particle Is
The first thing you have to do before deciding how big a dust particle is to know how much it weighs by weighting your particles. The best way to do this is to use the same device scientists use, called an electrometer.
There are two ways the procedure goes about. One method uses electricity, and another one doesn’t. Since we don’t want to risk ourselves with too much voltage, we won’t be using the latter method here. So I’m going to show you how you can measure the heavy something is without electricity:
- Using Paperclips and Scales: Place paperclip(s) on scales and note how much it weighs.
- Using a Scale and Thread: Tie thread to whatever scale you have, place whatever you want to measure the heavy it is on the opposite side of the weight that’s attached to the thread. Note how much it weighs.
Step 3: Measure How Big a Dust Particle Is
Measure how big a dust particle is by measuring how small they are compared to paper clips. In this step, we’re actually going to compare how small a dust particle is compared with how big a paperclip is, or vice-versa depending on how you see it.
The best way would be to use two microscope slides, one which has dust particles and another which doesn’t, in order for us not to get them mixed up in identifying what scale one of them is.
Put one slide on top of the other and line up the dust particles with a paperclip such that they’re touching it (you might need to add another piece of dust or even some tape if you can’t get them to stick). As we measured the big a dust particle was in step 2, we will measure how small it is compared with how big a paperclip is, which means how big it is compared with smaller than big a paperclip is.
Step 4: Find Out How Dense the Dust Actually
Find out dense the dust actually is by seeing how many pieces of Dust fit into one cubic centimeter volume of space. In this step, we’re going to measure how much space does one volume filled up with dust using our recently used length measurement of how big the paperclip is.
Take a ruler or any length measuring tool you have at hand and measure how long one side of your microscope slide is, which has dust particles on it. Once done, place the other microscope slide on top of it where you can see how much space does one volume fills up with dust take how many pieces of dust fit in there. Now take another ruler or other length measuring tool to measure how big a paperclip is and compare how small they are compared with how big a paperclip is so we know how much space does one volume filled up with dust takes.

Some Other Way to Measure Dust in The Air
1. Air Sampling Pumps
Air sampling pumps are an effective way to measure dust in the air. The pump draws in a specific volume of air over a set period, which can be used to calculate the concentration of dust in the air.
This is how corporations usually measure dust in the air. Some companies use chemicals such as ink to help them track how much dust has been released into the air. These methods, however, can be expensive and cumbersome.
2. Miniature Dust Sensor
A team of students from the University of Cincinnati has recently created a miniature dust sensor that is one hundred times smaller than its predecessor, which measures how much dust is in a room or a building every 15 minutes. This can help people who are suffering from asthma or other respiratory conditions to quickly get aid when they need it most.
3. Laser Scattering Sensor
This type of sensor works by using lasers to calculate how much particulate matter there is in the air; its device uses something called laser scattering. Laser scattering takes how much light is scattered into account to accurately measure how many dust particles there are in the air.
4. Optical Particle Counter (OPC)
The fourth method for measuring dust in the air is through the use of an Optical Particle Counter (OPC). The OPC uses a laser to detect and measure the size of the particles in the air. It is a very accurate method of measurement and can be used to measure both large and small particles.
This sensor has a laser and a light detector that counts how many particles pass through the beam. It measures up to 1,000 particles per cubic centimeter (0.06 cubic inch).
The OPC is the most accurate instrument for measuring dust in the air because it can detect such small concentrations of airborne particles.
5. Condensation Particle Counter (CPC)
The fifth method for measuring dust in the air is through the use of a Condensation Particle Counter (CPC). The CPC uses a cooled mirror to measure the size and number of particles in the air.
The sensor has a laser and a light detector that counts how many particles pass through the beam. It measures up to 10,000 particles per cubic centimeter (0.6 cubic inches).
The CPC is not as accurate as the OPC, but it can measure both large and small particles; if you want to know more about how to measure dust in the air, keep reading.
6. Photometer/Nephelometer
The sixth method for measuring dust in the air is using a photometer or nephelometer. A photometer measures how much light is scattered by particles in the air, and a nephelometer measures how much light is transmitted by particles in the air.
This type of sensor is not as accurate as of the OPC or CPC, but it can measure large and small particles.

Probable Health Risks and Solutions
Airborne dust can be an insidious health hazard if not addressed properly. It is generally accepted that high levels of dust in the air can cause lung irritation, breathing problems, and even serious long-term damage to our respiratory systems.
Fortunately, there are ways to reduce airborne dust before it becomes a threat to our health. Regular vacuuming, damp mopping, proper ventilation, and frequent cleaning of HVAC systems can all help reduce the amount of particulate matter in the air and protect us from these potential hazards.
In addition, using exhaust fans in bathrooms and the kitchen will help keep those rooms clean and hygienic by quickly removing any airborne particles that may have been created while cooking or showering.
Taking these preventative steps will ensure that we are keeping our indoor air quality in check before it becomes a serious issue.
