How Poor Indoor Air Quality Can Affect Your House

At Shumate, we are committed to helping all Nashville-area residents understand the importance of improving and protecting their homes' indoor air quality.

Your furry friend has a cough

Did you know that pets can suffer from allergies, too? If you've noticed your dog or cat is coughing or has difficulty breathing, you should consult with their vet. Your pets, especially if they are mainly living indoors, are signaling that you need to check the indoor air quality of your home. During high pollen counts and poor air quality alerts, keep doors and windows shut and only let your pets outside when they need to. Keep air purifiers running constantly and make sure you dust and wipe down surfaces regularly. It's also important to keep your pets groomed, as they can bring in allergens and irritants.

You have increased mold growth in your home

Bathrooms, kitchens, and laundry rooms will understandably be temporary sources of excess moisture in your home, but when that moisture becomes more permanent due to lack of draining or drying, that's when you are at risk for damaged indoor air quality. Mold and mildew will quickly grow. Mold growth can also cause drainage problems within your home's pipes which can lead to a host of other issues. If you're noticing more mold or mildew, make sure your vent fans are running in your home's bathroom, check and regularly replace the air filters in your home's HVAC system, and if moisture retention becomes a constant problem, dehumidifiers might be a helpful tool to keep your home free of mold and mildew.

You are having to replace air filters more often

Your home's HVAC system and air purifier units require regular replacement in order to function properly and efficiently. HVAC filters should be replaced every three months, and air purifier filters are replaced every 6-12 months if they are HEPA filters. If, however, you're noticing that you have to replace those filters sooner than the recommended timing, you should start looking around your home for sources of indoor air pollution. Replacing filters more often is a hassle and an extra expense, but it also means your HVAC system and air purifiers are working harder, which means they will wear out sooner and ultimately need to be replaced prematurely.

Common sources of indoor air pollution include:

  • Fuel-burning combustion appliances like gas stoves

  • Tobacco or smoking products

  • Building materials and furnishings as diverse as:

    • Deteriorated asbestos-containing insulation

    • Newly installed flooring, upholstery or carpet

    • Cabinetry or furniture made of certain pressed wood products

  • Products for household cleaning and maintenance, personal care, or hobbies

  • Central heating and cooling systems and humidification devices

  • Excess moisture
