Curious about how to test home air quality? Don’t look any further. There are different ways to test your home’s air quality.

You can use a testing device or hire an indoor air quality specialist. Either option is good. Radon and mold tests are usually recommended to test home air quality and other home tests when buying a new home. If you want an accurate way to test the air quality in your home, you may consider hiring a specialist.

Most people believe that if they dust and clean their homes regularly, they will be safe from harmful particles. However, this is not always completely effective. Sometimes, your home may still have air pollutants that general cleaning can’t remove.

And, with air pollutants being microscopic, they are not usually visible to the human eye. That is why you need to test the air quality in your home. But how can you test your home air quality?

In this guide, we’ll explore how to test the air quality in your home. We’ll walk you through how they work, the types of air pollutants they test, and ways to reduce those air pollutants.

How to Test Home Air Quality

Often, we overlook the importance of a home air quality test. Testing the quality of your home’s air can assist you in detecting air pollutants. It can also reduce your energy bill by improving the efficiency of your HVAC system. 

If you want a thorough test of your home air quality, you’ll need to use a combination of several tests. You’ll also need to know which air pollutants you want to test. Below are the most common ways how to test home air quality:

Home Air Quality Testing MethodPros of this Method
Indoor Air MonitorYou can monitor several indicators at once and get real-time feedback.
Mold TestingCan detect many different kinds of molds and goes deep into places other tests might not catch.
Radon TestingCan prevent long-term health problems and let you know if your home need structural attention.

1. Install an Indoor Air Monitor

An indoor air quality monitor checks and analyses the air quality in your home. This is also one of the easiest approaches to employ when learning how to test home air quality.

Just be sure to choose a monitor that best suits your needs. For example, suppose you live in a heavily polluted area. In that case, you should opt for an indoor air quality monitor to detect particulate matter. However, if you live in an older house, you may want to invest in a model to detect carbon monoxide and radon.

What Does It Test?

Some indoor air quality monitors have electrochemical biosensors that detect air pollutants. In comparison, others detect traces of particle matter when they pass in front of the laser. While a few detect traces of carbon monoxide and formaldehyde.

Depending on the type of indoor air monitor, they can also pick up traces of volatile organic compounds (VOCs) in your home. Advanced indoor air quality monitors can also detect any changes in humidity and temperature.

‍How Does It Work?

Most indoor air quality monitors have a screen panel that displays the current levels of air pollutants. Others indicate a comprehensive overview of your home air quality through an app. The app also includes instructions on how to test home air quality.

The good news is that most indoor air quality monitors are rechargeable, so you won’t have to buy new batteries all the time. Besides that, some advanced indoor air quality monitors have smart home connectivity. So you can pair it with other home appliances, such as thermostats. This way, you can monitor your air quality and optimize your energy consumption.

2.  Mold Testing

Second in our list of how to test home air quality is mold. The mold that grows from bread that has been left for an extended time is easily noticeable. However, mold spores found in your home are less noticeable and pose a more significant risk to your health.

It would help if you did mold tests more often to limit exposure to you and your family. In addition, it’s easier to remove mold once it is detected.

What Does It Test?

Indoor air quality monitors can’t detect mold. Therefore you need mold tests. A mold test is ideal for determining if you have a mold problem in your home, especially if you aren’t sure because you haven’t noticed anything.

Suppose you’re coughing or out of breath more frequently, then it’s a telltale sign that there is possibly mold in your home. In addition, if you notice a musty odor coming from your home, you should push for a mold test.

How Does It Work?

Mold tests come in different types. For example, swabs and tape strips capture mold spores on surfaces such as tables. It takes a few minutes to receive your results. However, the results will not be able to tell you the type of mold in your home.

Unlike swabs and tape strips, you’ll be required to give the sample to a lab for analysis for air pumps. While these tests provide more accurate results than a swab test, it can take several days or weeks to receive feedback.

On the other hand, Petri dishes are placed in your home with a substance so that mold can grow. Make sure the petri dish stays closed. You leave it for a while for it to incubate.

If the mold grows in the Petri dish, you have mold. However, if it doesn’t grow, you don’t have mold in your home. The incubation period varies depending on the brand, so check the manual for the exact specifications. 

3.  Perform a Radon Test

Up next in our list of tips on how to test home air quality, radon has no odor, color, or taste. It is practically undetectable without a home test. Radon enters your home through gaps in your floor, walls, and other areas such as ducts. Because radon is a by-product of uranium deposits found in the soil, you can find it in low concentrations in your home.

Unlike most air pollutants, radon causes significant health problems. According to the American Cancer Society, long-term radon exposure has been related to the deaths of 21,000 people from lung cancer.

What Does It Test?

Radon tests detect the presence of radon in your home. They include long-term and short-term tests. While long-term, tests can last up from 90 days to several months. Short-term tests such as charcoal canister can detect radon for 2-7 days.

How Does It Work?

Short Term Radon Tests

For a short-term test, you can put the test object in the area closest to the ground or beneath the ground. Keep it there for at least three days to a week.

It’s essential to keep your windows and doors shut where you place the test until it is complete. In addition, avoid touching the test because it increases the likelihood of contamination, altering the results.

After the test is complete, you must send it to the lab to get your results. The results will indicate the level of radon in picocuries per liter. If the values are higher than five ppm (picocuries per liter), don’t be alarmed. You can hire a specialist to seal up any gaps to reduce and prevent further radon infestation in your home.

The specialist can also use soil suction to reduce radon levels. This involves taking pressure pipes and placing them into the floor and soil beneath your home. It creates a way for radon to escape instead of recirculating in your home. HVAC filters can also reduce radon levels.

Long-Term Radon Tests

Long-term tests can provide an accurate analysis because radon levels change throughout the year owing to weather and other causes.

You can purchase two charcoal packets and install them at the lowest level of your home, such as the basement. Furthermore, make sure they are 20 inches above the floor, ideally at your breathing levels.

Also, please keep it one foot away from walls and three feet away from windows and drafts. Furthermore, do not place it in areas with high humidity, such as bathrooms and laundry rooms, or areas with high temperatures, such as fireplaces.

4.  Use a Carbon Monoxide Detector

Next in our list for how to test home air quality, carbon monoxide, like radon, has no smell or flavor, and it’s colorless. It is released from fuel combustion from appliances such as gas dryers, furnaces, and notably gas stoves. Fireplaces also produce a considerable amount of carbon monoxide.

Short-term exposure to carbon monoxide at a low concentration can cause disorientation and migraines. In contrast, long-term exposure to carbon monoxide can be fatal.

What Does It Test?

Carbon monoxide tests and detectors are a relatively simple technique when learning how to test the air quality in your home. Most detectors measure carbon monoxide concentration from zero ppm (parts per million) to 1 ppm in your home and alert you if anything changes.

How Does It Work?

Some carbon monoxide detectors need batteries. However, others need to be plugged into your wall. An electronic portable toxic multi-gas monitor is the best option for testing carbon monoxide in your home. 

It differs from conventional carbon monoxide detectors in that it can detect even trace amounts of the gas. In addition, it is also battery-powered.

To use it, unbox it, and place it near a smoke detector in the ceiling because it needs to monitor the air as it rises. Health problems can occur if it detects levels between 3 ppm to 70 ppm. Especially long-term exposure to 70 ppm can lead to death.

That’s why it is the best option because you can place it at a higher height. Make sure to keep it a distance from a fireplace or a flame.

5.  Volatile Organic Compound Tests

Finally on how to test home air quality, volatile Organic Compounds (VOCs) are air particles that can contaminate water and gases. They are made up of chemicals released from paint, gas stoves, air fresheners, and cleaning products.

In addition, VOCs are a significant source of concern because concentrations within your home can be five times higher than outside. They can also have severe short and long-term health impacts.

What Does It Test?

Volatile Organic Compound tests include home air kits used to detect different types of VOCs such as formaldehyde.

How Does It Work?

You can install some VOC tests throughout your home for continuous VOC testing. The tests take an accurate reading for volatile organic compounds. Because most of these tests are connected to your computer, you can easily download the readings.

To get the exact quantity of specific VOCs, you can use sorbet tubes or summa canisters. They enable you to collect the air and send it to the lab for analysis.

However, these tests cannot pinpoint the exact source of the VOCs in your home. Instead, you’ll need to figure out which products emit VOCs. Check your cleaning products, candles, and other products in your home that may be releasing VOCs.
