What Causes Indoor Air Quality Problems?

Poor Indoor Air Quality Most people associate polluted air with industries and urban centers and fail to acknowledge that the air within their homes could be equally polluted. As most people spend most of their time in their residential places, it is prudent to know what causes indoor air quality problems.


Do you have your floor, carpet, and surfaces scrubbed spotlessly clean but you are still sneezing? Dust or other irritants could be the victims. Dust within your heating, ventilation and air conditioning unit due to irregular cleaning is a common cause of indoor air quality problem.

Carpet Fumes

Once a new carpet has been installed within a living space, its vinyl backing and the glue used to hold it in place produces fumes in a process known as off-gassing. This pollutes the air and may result in dizziness, nausea, headaches, and asthma aggravation. Rooms with new carpets should be well ventilated and aired for a minimum of 3 days.


Whether it be from stoves, cooking places, fireplaces or cigarettes, smoke is a major cause of indoor air quality problems. Prolonged exposure to smoke may cause or aggravate respiratory conditions, while continued smoking leads to lung cancer. Homes should be well ventilated to prevent smoke build-up. Smoking inside the home should be highly discouraged.

Household Cleaners & Disinfectants

While most of such substances will scrub your surfaces clean, most form Volatile Organic Compounds (VOCs) when they combine with the air you breathe. VOCs are also found in other common household materials such as paints and paint removers, adhesives, building materials, and office equipment. Short-term effects of VOCs are shortness of breath, dizziness, and headaches while it may lead to cancer in the long-term


Mold is common in warm, damp, and dark places in our homes. Such can include places like basements and attics. Leaks in the plumbing pipes within the walls may also cause molds to grow on the wall’s surface. This causes allergic reactions, development of respiratory conditions, and worsening of asthmatic reactions.

Understanding what causes low-quality indoor air will help you know how best to take care of this problem. One of the most effective ways of safeguarding the quality air within the home is to install an HVAC system and have it undergo regular maintenance and inspections. This will keep its air ducts free of dust, dirt, and other air pollutants.
