How To Improve The Indoor Air Quality In Your Home: Easy Methods To Try Today

How to Improve the Indoor Air Quality in Your Home: Easy Methods to Try Today

Americans spend up to 90% of their time indoors, especially during colder winter months. While staying inside may feel warm and comfortable, it can also expose you to hidden health risks. Modern construction methods and tight insulation have made homes more energy-efficient—but they also trap airborne pollutants inside. As a result, indoor air can often be more polluted than outdoor air.

When windows and doors remain closed for long periods, fresh air circulation is limited, allowing contaminants to build up. This contributes to increased allergy symptoms, respiratory issues, and general discomfort. Commercial spaces such as offices and shopping centers face similar challenges due to limited ventilation. Understanding where indoor air pollution comes from—and how to address it—can make a meaningful difference in your health and comfort.

What Is Sick Building Syndrome?

Sick Building Syndrome (SBS) is a condition linked to poor indoor air quality. It occurs when occupants experience health issues or discomfort that appear to be related to time spent inside a building, without a clearly identifiable illness or cause.

Common symptoms associated with Sick Building Syndrome include:

• Persistent coughing or chest tightness
• Nausea, dizziness, or headaches
• Fever, chills, or flu-like symptoms
• Muscle aches and general fatigue

Research has also shown that prolonged exposure to volatile organic compounds (VOCs)—chemicals commonly found in household products, paints, and building materials—can increase long-term health risks, including certain cancers. Improving indoor air quality is one of the most effective ways to reduce these risks.

Easy Ways to Improve Indoor Air Quality at Home

Improving indoor air quality does not require major renovations. Small, consistent changes can significantly reduce pollutants and improve the air you breathe every day.

Keep Your Home Clean

Regular cleaning helps remove dust, pet dander, and other airborne particles that settle on surfaces. Vacuuming with a HEPA-filter vacuum, washing bedding frequently, and minimizing clutter all help reduce the buildup of indoor pollutants. Avoid harsh chemical cleaners when possible, as they can release VOCs into the air.

Increase Ventilation

Fresh air circulation is one of the most effective ways to improve indoor air quality. Opening windows—even briefly during colder months—helps flush out stale air and bring in fresh outdoor air.

Additional ways to improve ventilation include:

• Running exhaust fans in kitchens and bathrooms
• Using attic or whole-house fans when available
• Installing or upgrading to a filtered air-conditioning system for allergy-sensitive households

Consistent airflow helps prevent pollutants from lingering indoors.

Eliminate Mold and Control Humidity

Mold thrives in damp environments and can significantly impact indoor air quality. Keeping indoor humidity levels balanced is essential for mold prevention.

Helpful strategies include:

• Using exhaust fans during showers and cooking
• Running dehumidifiers in moisture-prone areas like basements
• Fixing leaks promptly to prevent water accumulation

If mold growth is widespread or persistent, professional remediation is essential to fully resolve the issue.

Use Houseplants to Support Cleaner Air

Certain houseplants can help reduce indoor pollutants while adding natural beauty to your home. Plants absorb carbon dioxide and can help mitigate the effects of some airborne toxins.

Popular indoor plants known for air-quality benefits include:

• Peace lilies
• Ferns
• Aloe vera
• English ivy
• Chinese evergreen
• Rubber plants

While plants should not replace ventilation or filtration, they can complement other indoor air quality improvements.

Choose Low-VOC or Zero-VOC Paints

Traditional paints and finishes often contain high levels of VOCs, which release gases into the air through a process known as off-gassing. These emissions can linger long after painting is complete.

Today, many manufacturers offer low-VOC and zero-VOC paints that significantly reduce chemical exposure. Choosing these products allows you to refresh your home’s appearance while improving indoor air quality at the same time.

Consult an HVAC Specialist

Professional HVAC services play a major role in maintaining clean indoor air. Heating and cooling specialists can inspect and clean air ducts, removing accumulated dust, pollen, mold spores, and pet dander that circulate through your home.

HVAC professionals can also recommend and install advanced indoor air quality solutions, including:

• High-efficiency air filtration systems
• Whole-home air purifiers
• Ultraviolet (UV) lights to inhibit mold and bacteria growth in ductwork

These upgrades provide long-term improvements and are especially beneficial for households with allergies or respiratory sensitivities.

There’s No Place Like a Healthy Home

Understanding what contaminates your indoor air—and how to address it—puts you in control of your home’s health. By cleaning regularly, improving ventilation, controlling humidity, choosing healthier materials, and working with HVAC professionals, you can create a safer, more comfortable living environment.
