A Landlord’s Guide to Different Types of Indoor Air Quality Testing

The biggest frustration for any landlord is when you turn off the boilers for the night, only for them to be switched on in the morning to deal with an issue that arose during the night.

Poor indoor air quality can cause all kinds of problems, from exacerbating allergies to causing illnesses. Are you wondering if you have the right testing in place in terms of your buildings?

We’ll cover several different types of indoor air quality testing that you should consider getting done. This will help you understand where the problem arises in your establishment and where to focus your attention.

Let’s begin!


IAQ Testing

IAQ testing measures a variety of particles, such as mold, dust, pollen, and bacteria, as well as levels of gases such as carbon dioxide, carbon monoxide, and ozone. These tests help landlords determine the overall quality of the air inside the property, identify potential airborne hazards, and mitigate risk.

Landlords should consider different types of IAQ testing to evaluate air quality more accurately and effectively. These options include testing for microbial contaminants (e.g., bacteria, molds, and viruses), chemical hazards (e.g., formaldehyde, asbestos, and other VOCs), and gaseous pollutants (e.g., carbon dioxide and ozone). Once the testing is complete, landlords can take the necessary steps to improve air quality, such as installing an air purifier, as well as implementing steps that prevent future air quality concerns. 

Mold Spore and Mycotoxin Tests

Air quality testing is an important part of a landlord’s guide to the proper maintenance of the dwelling unit. Mold spore and mycotoxin tests should be conducted to identify any potential health hazards arising from mold growth on the property. The tests measure the levels of airborne mold spores and microscopic fungal organisms in all indoor environments.

They also measure the levels of airborne mycotoxins, which are metabolic byproducts of some types of mold growth. Once the presence of mold and/or mycotoxins is detected, the landlord can move forward with appropriate measures to remove and/or remediate any indoor air quality issues.

An important consideration for landlords is to obtain test results from a qualified laboratory that has experience and proficiency in testing for mold and mycotoxins. These tests can help identify any potential health hazards that can be attributed to indoor air quality.

Volatile Organic Compounds (VOC) Testing

VOCs are pollutants created by many everyday items, such as furniture, building materials, and cleaning products. VOC testing helps identify these pollutants in the air and determine if levels are unsafe. Tests generally involve air sample collection from different heights and locations throughout the property and periodic checks to ensure the highest indoor air quality levels.

The results create an action plan to limit and reduce VOC emissions, thus providing an improved and healthier home. Landlords should ensure that qualified professionals conduct all VOC testing to ensure accurate results and a proper action plan to minimize VOC exposure for tenants.

Formaldehyde Testing

Formaldehyde is a colorless, strong-smelling gas used in various household items and building materials. This gas has been linked to various respiratory illnesses and other health issues, and proper testing is important. Testings typically involve sampling the air in various areas of the home as well as measuring the amount of formaldehyde present.

Test results should be compared against set industry standards and recommendations. Professional testing services can eliminate the guesswork and can provide landlords with accurate, dated results. Proper documentation and results should be discussed with tenants to keep everyone informed about the air quality in the home.

Particulate Matter Analysis

Particulate matter, also referred to as particulate pollutant, is a type of air pollutant that consists of tiny pieces of particles like dust, dirt, and smoke. A form of indoor air quality testing, particulate matter analysis is used to measure the number of these particles in a particular area. To address any potential issues of particulate matter, a landlord should have the area tested to quantify the airborne particulate matter levels in the home.

The results of such a test might impact the air quality and the type of ventilation system that must be used to improve indoor air quality. Also, landlords should educate the tenants on the necessary steps to properly maintain air quality, such as regularly cleaning and dusting living spaces and ensuring proper ventilation due to appliances and fans. Landlords should provide clear guidance to ensure tenants are well aware of their responsibilities in maintaining a healthy indoor air environment.

Air Sample Testing

Indoor air quality testing is important for landlords to understand to ensure the tenants’ health and safety. Air sample testing is one of the most common forms of testing. This type of testing uses a specialized air testing device to measure the number of indoor air pollutants such as mold spores, dust, and other irritants. During the sampling, areas of potential concern are surveyed, and indoor air samples are taken throughout.

The results are then used to determine the level of airborne contaminants in the indoor environment. Air sample testing can help landlords catch problems early and guide corrective actions to prevent further tenant harm. However, depending on the situation, other types of testing, such as surface sampling and biological testing, may also be necessary. Landlords should be aware of all their options when it comes to indoor air quality testing to ensure the safety of their tenants.

Static Pressure Testing

Static pressure testing is a type of indoor air quality testing employed by landlords to measure airflow through multiple areas in a structure and determine which areas need improved air circulation. The test measures the air pressure before and after passing through a particular space.

The test helps the landlord determine which upgrades would benefit the indoor air quality of a structure. For example, upgrading HVAC filters, adding air vents, or replacing ductwork may improve a building’s indoor air quality. Static pressure testing helps the landlord identify the most cost-effective improvements the structure requires to maintain or improve its indoor air quality. 

How to Maintain Good Indoor Air Quality

Landlords must consider the different types of indoor air quality testing that can be used to assess the air quality within their buildings. Air samples can be collected to test for airborne contaminants to see if it is impacted by pollutants such as pollen, VOCs, and fungal spores. Testing devices such as HEPA filters can be used to measure air particle-level pollutants, while carbon monoxide detectors can identify high levels of carbon monoxide in buildings.

Lastly, thermal imaging cameras can help identify the presence of mold and moisture buildup, which can lead to various respiratory issues. Knowing the results of these tests allows landlords to take the necessary steps to maintain good indoor air quality, such as opening windows, reducing air temperature, improving air circulation, and cleaning regularly.

Crafting an Appropriate Testing Plan

Air quality testing can help to identify and resolve issues before they become serious or harmful. All indoor air quality tests should be appropriate for a specific location, as different settings require particular protocols and measurements.

The testing results should be analyzed and used to develop an appropriate plan of action for improving indoor air quality. This may involve changing certain habits and practices, such as limiting smoking inside the building or improving ventilation.

Considerations for Selecting a Professional Testing Company

When selecting a professional testing company, factors such as air test type, cost, experience, qualifications, and reliability should be assessed. Costs for the various tests will vary, and selecting a reliable company with experienced technicians can minimize costs and ensure accurate results.

Checking for certifications, qualifications, and proof of insurance is key when selecting a professional testing company. Additionally, landlords should speak with past clients and read reviews to ensure that the company is reputable, reliable, and professional. Knowing the details of the various types of indoor air quality tests and selecting the right professional testing company are crucial steps to ensure proper safety and health standards.
