How a Lack of Fresh Air Can Lead to Higher CO2 Levels

Maintaining cleaner indoor air quality is essential for the continuous good health of everyone in your home. Carbon dioxide (CO2) is one contaminant that few people consider when addressing indoor air purity.


Since you exhale CO2 with every breath, it’s important to ensure your house has effective air circulation. Here are a few factors that affect your Cutler Bay air quality control.


Exhalation Adds More CO2 to the Indoor Environment

Each time you exhale, you’re depositing more CO2 into your indoor environment. When you live in a sealed or closed home, the CO2 levels will continue to build up with every breath you take. You can clear the carbon dioxide from your home by opening enough windows to clear this gas from your living spaces.


Gain a better understanding of CO2 levels in your home with professional air quality testing.


Poor Ventilation Increases the Concentration of CO2

When addressing Cutler Bay air quality control, consider your home’s ventilation. While opening your windows dilutes carbon dioxide, it’s not always possible to keep your windows open. On cold or stormy days, you’ll close your windows and seal the CO2 in your living spaces. 


For these instances, you’ll need other air filtration methods to counteract the buildup of carbon dioxide.


Insufficient HVAC Maintenance Prevents Proper Air Filtration

One way to make sure your home isn’t accumulating carbon dioxide is to maintain an efficient HVAC system. This involves scheduling semi-annual tune-ups with your HVAC company. 


Additionally, make sure you change the system’s air filter every 30 days. These actions will make it easier for your heating and cooling systems to filter the treated air.


Larger Households Multiply CO2 Buildup

While practicing proper HVAC maintenance is an effective way to manage CO2 levels, you might need some extra assistance. This is especially true in a home with multiple people continuously exhaling carbon dioxide. You can dilute this gas by installing a whole-home air purification system.
