HomeBlogThe Importance of Indoor Air Quality During the Summer

As the summer heat intensifies in Tampa Bay, we all seek refuge in the cool comfort of our homes. While maintaining a comfortable indoor temperature is crucial, it’s equally important to pay attention to indoor air quality (IAQ). Poor IAQ can affect your health, comfort, and overall well-being. Here’s why indoor air quality is particularly important during the summer and how you can keep the air in your home clean and healthy. 

How Summer Heat Affects Indoor Air Quality

  1. Increased Humidity: Summer often brings high humidity levels, which can lead to increased moisture indoors. Excess humidity can cause mold growth, dust mites, and other allergens to thrive, negatively impacting air quality.
  2. Closed Windows and Doors: To keep the heat out, we tend to keep windows and doors closed, reducing ventilation. This can trap indoor pollutants such as dust, pet dander, and volatile organic compounds (VOCs) inside the home.
  3. Air Conditioner Use: While air conditioners keep us cool, they can also circulate dust, pollen, and other allergens if not properly maintained. Moreover, poorly maintained AC systems can become breeding grounds for mold and bacteria.
  4. Increased Pollutants: Activities like cooking, cleaning, and using personal care products can release pollutants into the air. With limited ventilation, these pollutants can accumulate, degrading indoor air quality.

Tips for Maintaining Healthy Indoor Air Quality

  1. Regular HVAC Maintenance: Ensure your air conditioning system is regularly serviced to maintain its efficiency and prevent the buildup of dust and allergens. Replace or clean air filters every 1-3 months to keep the air clean.
  2. Use a Dehumidifier: To combat high humidity levels, use a dehumidifier. This can help prevent mold growth and reduce dust mites, making your indoor air healthier.
  3. Improve Ventilation: Even though you may want to keep the heat out, it’s important to allow fresh air to circulate. Use exhaust fans in the kitchen and bathrooms to remove excess moisture and pollutants. Occasionally open windows during cooler parts of the day to let in fresh air.
  4. Keep Your Home Clean: Regular cleaning can significantly improve indoor air quality. Vacuum carpets and upholstery frequently using a vacuum with a HEPA filter. Dust surfaces with a damp cloth to prevent dust from becoming airborne.
  5. Control Indoor Pollutants: Minimize the use of products that release VOCs, such as certain paints, cleaning products, and air fresheners. Opt for natural or low-VOC alternatives whenever possible.
  6. Use Air Purifiers: Consider using air purifiers with HEPA filters to capture airborne particles, including dust, pollen, and pet dander. Place them in commonly used areas like living rooms and bedrooms for optimal effect.
  7. Houseplants: Adding houseplants can help improve indoor air quality. Plants like spider plants, snake plants, and peace lilies can naturally filter out common indoor pollutants.
  8. Maintain Humidity Levels: Aim to keep indoor humidity levels between 30-50%. This range is optimal for comfort and prevents mold and dust mites from thriving.
