What is DIY Air Quality Testing?

DIY Air Quality Testing refers to conducting indoor quality testing using home testing kits, also known as DIY test kits.

This method is the more straightforward indoor air quality testing approach because the kits are usually available in markets. The “Do it yourself” test kits typically come with detailed instructions on how to use the materials, and after the test has commenced, these kits also give users a complete report of the house’s air quality.

The affordability of DIY kits gives users the leisure to test their homes or workplaces regularly and prevent risks of health complications due to poor indoor air quality.

 Types of DIY Air Quality Tests

 Outdoor air quality tests

Outdoor air quality tests measure the air pollutants and allergens in public spaces. As well as different kinds of harmful, even poisonous, gas.

This identifies the presence of contaminants that may harm multiple people and can harm public health in significantly overpopulated areas.

Indoor air quality tests

On the other hand, indoor air quality tests measure environmental pollutants, dust mites, and volatile organic compounds commonly present in a house or other indoor settings.

Testing indoor air quality is essential because people are most likely to spend a lot of time indoors, given the outgoing pandemic we are facing right now.

How DIY Tests Work

Air Quality Sensors

The DIY test kit comes with air quality sensors that work as detectors for pollutants, including carbon dioxide, carbon monoxide, dust particles, and other harmful substances that can pose serious health risks, work by collecting and analyzing air samples for the detection of detrimental to the amount in the air.

How To Conduct DIY Test Kits

Accomplishing air excellent tests involves taking the sensor and inserting it into the room or area desired to be tested. The sensor then collects air samples over a particular period, and the consequences are displayed on the device’s display screen.

Professional Air Quality Testing

Professional air quality checking refers to a single or group of professionals that reads the levels of air pollutants, including dirt, chemical substances, and gases, in an indoor or outdoor setting.

In this kind of testing, professionals measure the supply of pollutants and discover their health effects on people. Leaving the job of monitoring air quality to experts, people may have more time to focus on different areas of their lives without worrying about whether or not their house or workplace has poor air quality.

Types of Professional Air Quality Tests

 Contaminant-Specific Testing

Contaminant Specific Testing identifies the presence of specific air pollutants. This test helps determine the reason for air quality problems as it may accurately identify the exact contaminants causing the issue.

Additionally, it could provide a complete assessment and detailed report on the pollutants essential for promoting clean air quality.

Indoor Air Quality Assessment

Indoor Air Quality (IAQ) tests examine an area’s air quality. These assessments check for factors affecting IAQ, including airflow, temperature, humidity, and occupancy levels.

IAQ tests are commonly performed in reaction to a family member or a co-worker’s sudden respiratory issues or can also be a proactive measure to prevent adverse health issues from rising.


Ventilation Evaluations

Ventilation evaluations monitor the effectiveness of the airflow quality in an area, commonly in buildings. Experts check whether or not there may be enough air circulation, whether the airflow ventilation system or air purifiers is adequately maintained, and whether or not it complies with construction guidelines.

Comparison of DIY Air Quality Tests and Professional Air Quality Tests

Cost Implication

DIY air quality tests are significantly affordable compared to professional air quality tests.

However, one must consider that DIY kits monitor a specific pollutant while professional tests cover various contaminants. Hence, the rate distinction is justified.


Professionals do professional air quality tests with years of experience and learnings about air issues. Consequently, the consequences are extra particular compared to DIY air first-class checks.


DIY air quality tests include easy instruction manuals that make the manner of assessment of the air quality of your home smooth and pressure-free.

On the other hand, professional air quality tests require an expert to visit your space and perform outdoor and indoor air quality monitor. The latter part is time-consuming and may affect one’s schedule.

  Maintenance and Calibration

Do it yourself test kits require testing more often to hold their accuracy. Professional air quality tests do not need you to have t often, but the maintenance of the equipment and systems used should be regularly maintained.

 Legal and Regulatory Compliance

Since it is also a business, professional air quality tests must comply with local authorities’ standardized rules. Being the handiest and non-public use, DIY air quality tests no longer require compliance.


Choosing between DIY and professional testing relies on your specific needs. Suppose you have observed that your home may be at a high risk for bad indoor air quality.

In that case, it can be wiser to ensure you receive accurate and reliable effects in a professional’s air quality testing.

DIY testing kits may be a perfect starting line for the ones on a tight budget. However, relying on DIY kit testing on your own may be risky while detecting lethal pollution like carbon monoxide and radon.


What are the symptoms of poor air quality in a house?

People living in homes with poor ventilation may have symptoms including nausea, dizziness, and irritability.
Many illnesses cause this type of disease, making diagnosis difficult for therapists.

How do you tell if the air in your house is clean?
