To help make things easier for you, we’ve put together a list of the five most important factors that affect indoor quality. Hopefully, this article proves to be useful when it comes to helping you best understand how to improve the indoor air quality in your homes.


Volatile Organic Compounds (VOCs) from new paint, flooring, and other furnishings can cause several health issues. Cleaning products can also introduce harmful chemicals into your space. Be sure to be meticulous about everything that’s used in your home. It would be best to opt for non-toxic products if the option is available.


Air circulation and ventilation are incredibly important when it comes to improving indoor air quality. Insufficient ventilation will trap the polluted air indoors. To avoid this from happening, we suggest that you keep the doors and windows open so that fresh air can get into your space. An exhaust fan will also do wonders when it comes to ventilation, so it would be worth considering as well if you have the resources to spare.


Many of you may not know this but humidity plays an important role when it comes to indoor air quality. You have to keep the humidity at an optimal level to ensure that the air is clean. Having too much humidity will cause mold to grow, while the lack of humidity can cause rashes and dry skin. If you find that your space is lacking in humidity, we recommend installing a humidifier as it can help raise the humidity in your home.

HVAC Issues

While your HVAC system is meant to improve the indoor air quality in your home, it can be a source of problems as well. Dust or dirt in the ductwork and other components can ruin your home’s indoor air quality. Excessive moisture can also cause mold and mildew to grow in your home. The only way to avoid this is to have your HVAC system regularly checked and maintained. 

Pets and Pests

Both your pets and pests can be a source of allergens. These allergens can cause the overall indoor air quality to drop significantly. If you or anyone you live with have any allergies, then it would be best to minimize your exposure to the allergens that trigger an allergic reaction. If you have many pets at home, we advise you to clean regularly. You’ll want to vacuum more frequently to ensure that you clean up all of the hair that your pet sheds.
