10 Simple Tips for Better Indoor Air Quality: Insights from HVAC Experts

Indoor air quality (IAQ) plays a crucial role in our overall health and well-being. With most people spending a significant amount of time indoors, it’s essential to ensure that the air we breathe is clean and healthy. Poor IAQ can lead to various respiratory issues, allergies, and other health concerns. Fortunately, there are simple yet effective tips that can help improve IAQ, and who better to provide insights than HVAC experts who specialize in creating and maintaining healthy indoor environments.

In this blog post, we will share 10 simple tips for better indoor air quality, as provided by HVAC experts. These tips are practical, easy to implement, and can make a significant impact on the air quality in your home. From proper ventilation to regular maintenance of HVAC systems, these tips are backed by expert knowledge and can help you create a healthier indoor environment for you and your family.

Tip 1: Change Air Filters Regularly

One of the most basic yet crucial tips for better IAQ is to change air filters regularly. Air filters are designed to capture dust, pollen, pet dander, and other airborne particles that can degrade indoor air quality. Over time, these filters can become clogged, reducing their effectiveness and allowing pollutants to circulate in the air.

HVAC experts recommend checking your air filters at least once a month and replacing them as needed. For most homes, it’s recommended to replace filters every 90 days or sooner if they appear dirty. However, homes with pets or individuals with allergies may require more frequent filter changes.

When replacing air filters, make sure to use high-quality filters with a minimum efficiency reporting value (MERV) rating of 8 or higher.

Tip 2: Keep HVAC System Clean and Well-Maintained

Regular maintenance of your HVAC system is essential for maintaining good indoor air quality. Dust, dirt, and debris can accumulate in HVAC components, reducing their efficiency and causing them to circulate pollutants in the air. Therefore, it’s crucial to keep your HVAC system clean and well-maintained.

Schedule regular professional maintenance for your HVAC system, including cleaning of air ducts, coils, and other components. This can help ensure that your HVAC system is operating at its best and not contributing to indoor air pollution. Additionally, make sure to keep the area around your HVAC unit clean and free from debris to prevent dust and dirt from getting pulled into the system.

Tip 3: Control Indoor Humidity

Maintaining proper humidity levels indoors is essential for better IAQ. Too much humidity can promote the growth of mold and mildew, while too little humidity can cause dryness and discomfort. HVAC experts recommend keeping indoor humidity levels between 30% to 50% for optimal comfort and IAQ.

To control indoor humidity, you can use a humidifier or dehumidifier, depending on the needs of your home. In humid climates, a dehumidifier can help remove excess moisture, while in dry climates, a humidifier can add moisture to the air. Make sure to clean and maintain these devices regularly to prevent the buildup of mold and bacteria.

You can also use your HVAC system to control humidity by using a humidification or dehumidification feature if it’s available. Consult with HVAC experts to determine the best approach for maintaining optimal humidity levels in your home.

Tip 4: Properly Ventilate Your Home

Proper ventilation is crucial for maintaining good IAQ. Ventilation helps to remove stale indoor air and bring in fresh outdoor air, reducing the concentration of indoor pollutants. HVAC experts recommend having proper ventilation in all areas of your home, including kitchens, bathrooms, and living spaces.

Make sure that all exhaust fans in your home, such as those in the kitchen and bathroom, are functioning properly and are vented to the outdoors. This helps to remove moisture, odors, and pollutants from these areas and prevents them from circulating throughout your home.

If your home is tightly sealed for energy efficiency, consider using mechanical ventilation systems, such as an energy recovery ventilator (ERV) or heat recovery ventilator (HRV), which help to bring in fresh outdoor air while recovering heat or energy from the outgoing air. These systems can help maintain good IAQ without compromising energy efficiency.

Tip 5: Avoid Smoking Indoors

Smoking is a major source of indoor air pollution and has detrimental effects on IAQ. Secondhand smoke contains thousands of harmful chemicals that can linger in the air for long periods and can be especially harmful to children, elderly individuals, and those with respiratory conditions.

HVAC experts strongly recommend avoiding smoking indoors and creating designated outdoor smoking areas away from the home.

Tip 6: Use Natural Cleaning Products

Many conventional cleaning products contain volatile organic compounds (VOCs) that can contribute to indoor air pollution. These chemicals can release harmful fumes that can irritate the eyes, nose, and throat, and can even lead to long-term health effects.

Switching to natural cleaning products, or making your own using simple ingredients like vinegar, baking soda, and lemon juice, can significantly reduce the levels of harmful chemicals in your indoor air. Look for cleaning products that are labeled as “low VOC” or “no VOC” to minimize their impact on IAQ.

Tip 7: Keep Indoor Plants

Indoor plants not only add beauty to your home but can also help improve IAQ. Plants naturally remove airborne pollutants and release oxygen, helping to freshen the air and create a healthier indoor environment.

Choose indoor plants that are known for their air-purifying properties, such as snake plants, peace lilies, and spider plants. These plants are relatively low-maintenance and can thrive in indoor environments, helping to naturally filter the air and improve IAQ.

Tip 8: Avoid Synthetic Fragrances

Synthetic fragrances, found in many household products such as air fresheners, candles, and cleaning products, can release harmful chemicals into the air and contribute to indoor air pollution. These chemicals can irritate the respiratory system and trigger allergies or asthma symptoms.

Opt for natural, unscented products or those scented with essential oils instead of synthetic fragrances. Open windows to allow for fresh air exchange and use natural methods, such as baking soda or vinegar, to remove odors from your home.

Tip 9: Regularly Clean Carpets and Upholstery

Carpets and upholstery can harbor dust, pet dander, and other allergens, which can degrade IAQ if not cleaned regularly. Vacuum carpets and upholstery at least once a week with a vacuum cleaner equipped with a HEPA filter to capture small particles effectively.

Consider having carpets and upholstery professionally cleaned at least once a year to remove deep-seated dirt and allergens. If possible, opt for carpets and upholstery made from natural materials, such as cotton or wool, which tend to trap fewer allergens than synthetic materials.

Tip 10: Test for Radon

Radon is a radioactive gas that can seep into homes through the soil and foundation, and is a leading cause of lung cancer. Testing for radon is essential to ensure a healthy indoor environment, as radon is odorless, tasteless, and invisible, making it impossible to detect without proper testing.

Contact a certified radon testing professional to conduct a radon test in your home. If elevated levels of radon are found, mitigation measures can be taken to reduce the concentration of radon gas and improve indoor air quality.


Indoor air quality is crucial for the health and well-being of you and your family. Implementing these 10 simple tips can help you improve IAQ in your home and create a healthier living environment.

By maintaining a clean and well-ventilated home, using natural cleaning products, avoiding smoking indoors, keeping indoor plants, avoiding synthetic fragrances, regularly cleaning carpets and upholstery, and testing for radon, you can significantly reduce indoor air pollutants and promote a healthier indoor environment for you and your loved ones.

Remember to consult with HVAC experts and other professionals for guidance and assistance in implementing these tips. With proper care and attention, you can enjoy cleaner and healthier indoor air, leading to a better quality of life for you and your family.
