5 Bad Habits That Impact Your Indoor Air Quality

The quality of your indoor air can impact how you feel both physically and mentally. You may have several bad habits that are negatively impacting your indoor air quality. Considering some beneficial changes to your routine can make a big difference in IAQ and your overall health.

1. Skipping Routine HVAC Maintenance

It’s recommended that you schedule a routine inspection and maintenance for your HVAC system at least once a year. This process allows you to catch issues early before they have the potential to negatively impact your indoor air quality. Maintenance tasks include cleaning dirty interior components, addressing system strain, lubricating moving parts and more.

2. Not Changing Your HVAC Filter

The filter in your HVAC system should be replaced every 30 to 90 days. If you frequently forget to change this filter, your indoor air quality may suffer. Stay up-to-date with filter changes, and consider upgrading to a more effective type of filter. This can also protect the integrity of your HVAC system, reducing the need for repairs and lengthening the system’s lifespan.

3. Turning Off Your HVAC System

If the weather outside is pleasant, you may turn off your heating or cooling equipment to allow some fresh air in. While this is a great idea, don’t leave your equipment off for too long. Your HVAC system plays an important role in maintaining indoor air quality.

4. Using Fragrances and Cleaning Products Improperly

Chemical-based cleaning products and air fresheners have the potential to cause negative health effects. There are more natural options you can choose to support healthy indoor air quality and reduce your exposure to volatile organic compounds (VOCs). If you do need to use chemicals in your home, make sure to open your windows and doors and run exhaust fans to promote circulation and ventilation.

5. Practicing Bad Indoor Habits

Allowing people to smoke in your home will quickly degrade the quality of your indoor air and put you at risk of allergies, asthma attacks and other health problems. Other bad habits, like not cleaning up after your pets or not using your exhaust fans, can also have negative consequences. Wipe down surfaces in your home frequently, run ventilation equipment and make healthy choices that will support your IAQ.
