Indoor Air Quality (IAQ) plays an important role in overall wellness, including cardiovascular health. Because people spend most of their time indoors, the air inside the home has a direct impact on how the body and the heart functions every day.

How Indoor Air Quality Affects Heart Health

Poor IAQ can contain fine particles, allergens, and other pollutants that lower the quality of the air you breathe. When air quality is compromised, the body must work harder to deliver oxygen through the bloodstream. Over time, this added effort can place strain on the heart and circulatory system. In fact, indoor air can often be more polluted than outdoor air, especially in tightly sealed homes with limited ventilation.

The Importance of Proper Humidity Levels

Humidity plays a powerful role in how your air feels and how your body responds to it. When air is too dry, it can irritate your throat, nose, and lungs, making every breath feel less comfortable. On the other hand, air that’s too humid creates the perfect conditions for mold and other contaminants to thrive.

Keeping indoor humidity between 40–60%* helps air feel more comfortable and easier to breathe. Balanced humidity reduces airborne irritants, supports respiratory comfort, and creates an indoor environment that’s gentler on both your lungs and your heart so your whole body can breathe a little easier.

Filtration Helps Reduce Airborne Pollutants

Everyday activities—cooking, cleaning, pet dander, and even just moving around the house—release particles into the air. Without proper filtration, these pollutants continue to circulate throughout the home. High-quality air filtration captures dust, allergens, smoke particles, and fine pollutants before they spread throughout your home.

By removing these irritants, filtration helps create air that is easier to breathe and better for the respiratory system. Cleaner air supports better oxygen intake, which means the body doesn’t have to work as hard to deliver oxygen where it’s needed. Over time, reducing this extra strain can help support overall cardiovascular health and daily comfort.

Ventilation Brings in Fresh Air

Even the cleanest home can trap pollutants indoors. Chemicals from cleaning products, cooking fumes, moisture, and everyday activities build up when fresh air can’t easily enter. Ventilation systems solve this by continuously replacing stale indoor air with fresh outdoor air in a controlled, energy-efficient way.

Proper ventilation helps dilute indoor pollutants, manage moisture levels, and prevent air from feeling stale or heavy. It also supports more consistent air quality across the entire home, not just in one room. With steady fresh air coming in and stale air going out, your home feels lighter, healthier, and easier to breathe in every day.
