Thought air pollution was only a problem in the open air? The truth is that there is air pollution all around us, both inside and outside our homes. While indoor air pollution may be less visible than many of the outdoor air pollutants, we are familiar with, it may be more harmful to our health in many ways.

It is critical that we all work together to improve the quality of the air we breathe indoors. With our indoor air quality checklist, we will share our best tips for improving the air quality in your home.

There are numerous factors that can have an impact on the overall indoor air quality of your home. Use this checklist to self-assess the indoor air quality in your home. Pollutants in the indoor environment abound. Indeed, many of the household products you use (such as cleaners and aerosol sprays) may contribute to the deterioration of indoor air quality. We have listed some of the most common sources of indoor air pollution, as well as steps you can take to avoid contaminating your home’s air.

  1. Radon testing
    • Has your home ever been radon tested? Radon is a naturally occurring gas that has been linked to cancer in some people.
  2. Examine for Asbestos
    • Was your home built or remodeled with asbestos-containing materials? Asbestos is a mineral fiber that is known for its strength and heat resistance. As a result, it was widely used in things like fire retardants and building materials. Unfortunately, asbestos, like radon, has been linked to a variety of health issues, including lung disease.
  3. Select low- or no-VOC products.
    • Volatile organic compounds (VOCs) are a class of organic compounds that are added to household products for a variety of reasons. Unfortunately, we now know that many of these compounds, such as formaldehyde, contribute to health problems. VOCs can be found in a wide range of household products, including aerosol sprays, paint and paint strippers, dry-cleaned clothing, and many others. Choose products with low or no VOC labels whenever possible.
  4. Pesticides should be avoided.
    • It is reasonable to assume that anything sprayed outside your home can and will find its way inside. As a result, it is best to avoid pesticides whenever possible. If you must use pesticides in your yard or garden, make sure to follow the directions and keep your home’s doors and windows closed while doing so.
  5. Smoking is not permitted indoors.
    • It should come as no surprise that any type of smoke (tobacco, marijuana, even chimney smoke) can contribute to poor health. Furthermore, the nicotine, tar, and odors associated with smoking may stain your home permanently. Make sure your chimney flue is in good working order, and never smoke indoors.


You can improve your home’s indoor air quality by doing the following:


  1. Maintaining your home’s cleanliness. Dust, dirt, pet hair, and dander all have a negative impact on indoor air quality.
  2. Maintaining consistent humidity levels. Throughout the year, aim for a humidity level of 45 percent.
  3. Working with an HVAC professional to ensure your home is properly ventilated.
  4. Preventing the growth of mold and mildew. If you notice mold growth in any part of your home, you should contact a professional remediation specialist right away.
  5. Having your air ducts cleaned on a regular basis.
  6. Replace or clean your HVAC filter at least once every three months.
  7. Installing a whole-house air purifier or a portable air purifier in your home.
