Homeowners often consider indoor air quality testing necessary when they find noticeable issues with their homes. However, by the time dust bothers you and you detect a bad odor in your home, something is already fundamentally off track. 

Therefore, understanding the factors that impact indoor air quality is paramount to ensuring safe, breathable air for your family.

What Indoor Air Quality Really Means

Indoor air quality refers to the condition of the air inside your home. 

It can be influenced by factors such as:

• Ventilation
• Humidity levels
• Building materials
• Everyday activities

Even the smallest of changes to the ideal practices concerning these can make a huge difference to indoor air quality. 

Home environments are rife with airborne materials, gases, and moisture that can change drastically over time. Factors like reduced airflow or a difference in humidity can affect how you maintain healthy home air. 

Since the changes are often gradual, you may not immediately feel their impact.

What Influences Indoor Air Quality

Indoor air quality can drop dramatically if you do not pay attention to the physical discomfort that it may cause. 

Common Symptoms of Poor Indoor Air Quality

These are the signs that you must not ignore:

• Headaches or dizziness
• Persistent coughing or shortness of breath
• Fatigue or difficulty concentrating on tasks
• Nausea or chest tightness
• Worsening chronic allergy symptoms

Common Indoor Air Contaminants

What are the specific airborne contaminants that cause these?

• Carbon Monoxide (CO): It causes headaches, nausea, and dizziness.
• Particulate Matter (PM 2.5 to PM 10): These trigger coughing, shortness of breath, and fatigue.
• Volatile Organic Compounds (VOCs): These cause headaches and difficulty in concentration.
• Mold: These worsen your allergies and cause respiratory irritation.

Common Sources of Indoor Air Contaminants

The sources of these contaminants can be as varied as:

• Faulty heating devices
• Smoke
• Paint emissions
• Poorly ventilated spaces
• Humidity

Checklist to Mitigate Indoor Air Quality

You must be wondering: what is the checklist that can help me avoid degrading my home air quality inadvertently? Here is one:

• Ensure proper ventilation: Inadequate or uneven ventilation can cause airborne particles to linger for a long time, causing skin and respiratory issues.
• Maintain basic hygiene: To do this, you can take steps like dispelling smoke and particulate matter that might get introduced due to activities like cooking, cleaning, hobbies, renovation work, etc.
• Reduce indoor pollution sources: Limit smoke, fumes, and the formation of particulate matter caused by cleaning, cooking, and renovationwork.
• Maintain indoor cleanliness: Ensure regular cleaning to remove dust and other allergens.
• Control indoor humidity: You might want to use dehumidifiers to control indoor humidity levels for a pleasant experience. Both high and low humidity can impact household health negatively.
• Monitor combustion appliances: Regularly inspect heating devices and fuel-burning appliances to minimize the risk of carbon monoxide exposure.

Although doing these by yourself counts as a responsible action on your part, these are only general best practices, not case-specific, intentful action. 

Despite your best efforts, many things can still go wrong when building a safe home for your loved ones.

Further Causes of Air Quality Degradation

Air quality degradation can be more pervasive than you think, with its symptoms not immediately apparent. This makes meticulous indoor pollutant detection a priority, along with ensuring self-detection and awareness. 

These are two instances of why you need to stay on your toes when it comes to your family’s safety.

Combustion Sources and Residual Indoor Pollutants

You might think – Why would smoke or fumes cause an air quality issue if I have my rooms ventilated? True. Ventilation does solve the issue partly, but you cannot completely deep-clean your house of VOCs with natural ventilation. For instance, cigarette smoke alone has numerous VOCs that can affect even secondhand smokers.

According to the EPA, homeowners used air quality mitigation systems 611 percent more than they did in the 1990s through 2013.

What you cannot see can still affect how you feel. 

Residential exposure to radon, a naturally occurring radioactive gas, can affect occupant health adversely. This American Lung Association study points out that about 1 in 15 homes in the US are exposed to hazardous levels of radon-contaminated air. 

To be in the clear, your approach should be to opt for science-based, result-oriented solutions like InHaus Lab’s radon testing services.

Sick Building Syndrome (SBS)

If you have recently bought a new home, or are thinking of buying one, you must be wary of SBS, which arises out of faulty architecture. People often experience nausea, irritation of the nasal passages, headaches, and other symptoms upon entering certain spaces.

How do you detect that something is wrong with these spaces? 

Here’s how:

• Check if bodily discomfort increases after entering a particular space
• Take a careful look around to check for the presence of mold
• Check for musty odor and prevalence of damp spaces
• Be extra finicky about bathrooms, kitchens, and other wet spaces

Old constructions repurposed into office spaces have caused these issues in the past, as this Reddit user demonstrates. With a shift of workspace, employee illness dropped by 80%, which is a telling stat. 

In US cities like Minneapolis, MN, and Aspen, Colorado, the chilly seasons call for long periods of room-heating, causing a ventilation issue. If you are located in these areas, you have got our back!

Why Air Quality Testing Helps

As a conscious homemaker, you could often find that something is amiss in your home – whether it is overly dry or humid, stuffy, or has inconsistent conditions across rooms. 

The table below outlines the environmental factors that a home air quality assessment can uncover:

Unsure about which tests to run for your house? 

The following tests are commonly run by industrial hygienists for air quality inspection:

• Indoor Air Quality (IAQ) Testing: Identifies particulates, VOCs, and overall indoor conditions
• Mold Testing: Detects and addresses moisture-related issues
• Radon Testing: Detects radon exposure levels
• Indoor Odor Removal: Targets source control, filtration, and ventilation strategies

If you suspect any of these, you must opt for an indoor air quality inspection without any further delay.

Seeking Expert Opinion

Health and hygiene experts always stress the importance of maintaining consistently high air quality in the spaces you spend the most time. 

It is advisable to maintain basic hygiene levels at all times in the best interests of family members, apart from time-to-time indoor air quality testing.

The EPA suggests that secondhand smoke could expose non-smokers to serum cotinine levels of 1-10 nanograms per milliliter (ng/mL).

Such substances are actively linked to heart and lung disease, and can linger in your body for a considerable time, as this Quora user presents in a chart. 

If you are concerned with the well-being of your family, it is important to follow a science-first approach rather than guesswork. 

Thereafter, it is important to strategize with the help of concrete evidence and chalk out the next steps to improve your indoor air quality.

Taking the Next Steps 

Once you have understood the importance of clean, breathable air in your home, the next steps fall into place easily. If you are a busy homeowner with young kids at home or live with the elderly, it is time to get your home air quality tested.
