9 Strategies to Improve the Indoor Air Quality of Your Home

Surprisingly, the air inside your home can be more polluted than the air outside.

Why Indoor Air Quality Matters for Your Health

The air inside your home can contain harmful particles, pollutants, and allergens that affect your family’s well-being. Exposure to indoor air pollution—such as dust, pet dander, mold, pollen, and Volatile Organic Compounds (VOCs)—can lead to respiratory issues like asthma and allergies. Over time, prolonged exposure may even contribute to more serious health problems.

Common Indoor Pollutants to Watch For:

• Dust and Pet Dander: These allergens can aggravate asthma and allergy symptoms.
• Mold and Pollen: Mold thrives in damp conditions, while pollen enters through open windows and doors.
• Volatile Organic Compounds (VOCs): Found in household products like paint, cleaning supplies, and air fresheners, VOCs can contribute to poor indoor air quality.

Our team identifies sources of indoor air pollution and offers practical solutions, such as air purifiers, HVAC maintenance, and duct cleaning. These services help create a healthier breathing environment and improve your home’s indoor air quality.

Root Causes of Indoor Air Pollution

Indoor air can easily become contaminated by common pollutants found inside your home. Knowing where these pollutants come from and how to reduce them helps maintain a healthier environment.

Common Indoor Pollutants

“Mold, dust mites, insect feces and other particles in the air can trigger allergies and asthma attacks,” says Janice Nolen, assistant vice president of the American Lung Association in Washington DC.

These contaminants can negatively affect indoor air quality, especially for those with respiratory issues like asthma.

Improve Ventilation

One key step in managing indoor air quality is increasing ventilation. “Keep sources of pollution out of the home by ensuring you have good ventilation, both into and out of the house,” Nolen explains. Proper ventilation helps prevent the buildup of dust, mold, and bacteria.

Manage Humidity Levels

“A lot of mold, bacteria and other pollutants need moisture to grow. So keeping humidity levels below 50% and fixing leaks can help reduce risks,” Nolen says.

Moisture control is an absolute must. Excess moisture encourages mold growth and dust mites, both of which can trigger allergies. Dehumidifiers help reduce moisture in areas like basements and bathrooms, while fixing leaks prevents moisture buildup in the home.

Effective Strategies to Improve Indoor Air Quality

Improving the quality of air inside your home is directly linked to the cleanliness of the air you breathe. Various approaches can help achieve cleaner indoor air, starting with choosing the right air filter for your HVAC system. A high Minimum Efficiency Reporting Value (MERV) rating helps capture more airborne particles, leading to better air quality in your home.

The MERV rating system was developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to measure a filter's ability to capture particles of different sizes. Residential filters range from MERV 1 (least efficient) to MERV 16 (most efficient for home use). Filters rated higher than 16 are typically used in commercial settings, as residential systems are not designed to handle the airflow required.

1. Choose the Right Air Filter

Selecting the right air filter depends on your home’s needs and your specific goals for air quality. There are four types of MERV filters to consider:

• Low-Efficiency Filters (MERV 1-4): Suitable for larger particles like pollen and dust mites, but less effective for smaller pollutants.
• Medium-Efficiency Filters (MERV 5-8): Ideal for homes, capable of trapping particles as small as 3 microns, including mold spores.
• High-Efficiency Filters (MERV 9-16): Best for families dealing with allergies or respiratory concerns. These filters are often recommended as the most effective air filter for allergies, capturing finer particles like bacteria and lead dust.
• Ultra-Efficiency Filters (MERV >16): Commonly used in hospitals but not recommended for homes due to airflow limitations.

Make sure to replace air filters regularly—approximately every three months—to maintain their effectiveness.

2. Use Air Purifiers

Portable and whole home air purifiers can work alongside your HVAC system to target pollutants such as pet dander, smoke, and fine particulate matter. HEPA filters, in particular, are highly effective, capturing particles as small as 0.3 microns with up to 99.97% efficiency.

3. Add Indoor Plants

Want to know how to clean the air in your home naturally? Plants. Certain plants can naturally help purify the air. Popular choices include spider plants, snake plants, and peace lilies, which absorb toxins and produce fresh oxygen, helping to improve air quality indoors.

4. Maintain a Regular Cleaning Routine

Regularly vacuuming with a HEPA-filter-equipped vacuum, dusting surfaces, and washing bedding and curtains can reduce the buildup of dust mites, pet dander, and other allergens. This is key to keeping indoor air as clean as possible.

5. Reduce Chemical Pollutants

Lower the level of chemical pollutants in your home by minimizing the use of products that contain volatile organic compounds (VOCs). Choose natural or VOC-free alternatives for cleaning agents, paints, and air fresheners whenever possible.

6. Control Humidity Levels

Dehumidifiers are useful in damp areas of the home to keep humidity in check, particularly during hot and humid seasons. Lowering humidity reduces the likelihood of mold growth and dust mites.

7. Improve Ventilation

Allow fresh air to circulate through your home by opening windows when possible or using exhaust fans in the kitchen and bathroom. This helps remove stale air and introduces clean air, reducing pollutant buildup.

8. Test for Radon

Radon is a colorless, odorless gas that can enter homes through foundation cracks. Regular radon testing and mitigation of high levels are important, as radon is a leading cause of lung cancer.

9. Keep Smoking Outside

Cigarette smoke releases over 4,000 harmful chemicals into the air. Limiting smoking to outdoor areas dramatically improves the air quality inside your home.

Improve Indoor Air Quality with Professional HVAC Services

Maintaining your HVAC system plays an important role in improving the air quality of your home. Regular HVAC maintenance, air duct cleaning, and system upgrades help keep the air you breathe free from dust, allergens, and other harmful particles. These services keep your system functioning properly while providing a cleaner and healthier environment for your family.

Benefits of Regular HVAC Maintenance

A well-maintained HVAC system not only improves efficiency but also helps keep indoor air free from contaminants. Routine inspections and filter changes reduce the buildup of dust, mold, and other allergens that could circulate throughout your home. Regular air duct cleaning removes dirt and debris, preventing pollutants from entering your living spaces.

Upgrade to Energy-Efficient Systems

Investing in energy-efficient HVAC systems offers dual benefits. Not only do these systems help reduce energy consumption and lower utility bills, but they also contribute to better indoor air quality. Newer systems are designed to filter and circulate air more effectively, reducing the presence of airborne particles that may affect your family’s health. Investing in a whole home air purifier can also improve air quality by removing pollutants throughout the entire house, providing a cleaner environment for your family.

Why Professional HVAC Services Matter

When it comes to managing indoor air quality, professional services make a significant difference. HVAC experts can identify issues such as poor ventilation or air filter inefficiencies, offering targeted solutions that improve the overall air quality in your home. Trusting professionals ensures that your home’s HVAC system operates at its best, pro
