Easy Tips on How to Improve Indoor Air Quality at Home

Improving Indoor Air Quality Shouldn't Be Hard

Clean, fresh air is essential to a healthy and comfortable home, especially in Wake County, where outdoor air pollution and seasonal pollen can impact indoor air quality. Learning how to improve indoor air quality at home starts with addressing common indoor air pollutants like dust mites, pet dander, and volatile organic compounds that circulate through air ducts and HVAC systems. The Environmental Protection Agency warns that poor indoor air quality can pose significant health risks, from allergies to long-term respiratory issues.

Aire Serv of Wake County helps homeowners improve air quality by inspecting air conditioning systems, upgrading air filters, and adding air purifiers or natural ventilation solutions that reduce indoor air pollutants. With professional air cleaning and maintenance support, you can enjoy cleaner indoor air and better system efficiency year-round.

Key Factors Harming Indoor Air Quality (IAQ)

  • Common indoor air pollutants: dust mites, pet dander, mold spores, pollen, volatile organic compounds, tobacco smoke, and carbon monoxide.
  • Moisture and odor issues: excess moisture and poor ventilation cause mold and mildew growth, musty odors, and discomfort.
  • System performance: clogged air filters and dirty air ducts reduce air flow, strain HVAC systems, and increase energy costs.
  • Outdoor influence: outdoor air pollution and pollen can enter through open windows or outdoor air intakes, affecting indoor air.

By understanding these factors, homeowners can improve indoor air quality and keep HVAC systems running efficiently for cleaner, fresher air.

Signs Your Indoor Air Quality is Compromised

Small clues can reveal indoor air quality problems before they impact comfort or health.

  • Warning signs: persistent dust, musty or chemical odors, humidity swings, allergy flare-ups, and frequent air filter clogs.
  • System issues: clogged air filters, dirty air ducts, and low air circulation strain air conditioning and forced air heating systems.

If these signs persist, Aire Serv of Wake County can inspect your HVAC system, seal air ducts, and install upgraded air cleaners to restore clean, fresh air throughout your home.

Air Filter Guide: MERV Ratings and Replacement Tips

Air filters play a key role in improving indoor air quality and keeping HVAC systems efficient.

How to Choose the Right Minimum Efficiency Reporting Value (MERV) Air Filter

  • MERV 1–4: captures large dust and lint; basic home heating use.
  • MERV 5–8: traps dust mites, pet dander, and pollen; fits most air conditioning systems.
  • MERV 9–12: removes finer particles and smoke; ideal for reducing indoor allergens.
  • MERV 13–16: filters bacteria and pollutants; verify system airflow limits.
  • HEPA filter: very efficient collector for portable air cleaners or whole-home HEPA systems. A proper fit and seal maintain clean air and steady air flow.

How Often to Change Air Filters

  • Replace every 1–3 months or more often with pets, smoke, or heavy pollen.
  • Check filters monthly during Wake County pollen seasons. Regular changes keep air conditioning and forced air heating systems efficient.

Mistakes to Avoid in Changing Air Filters

  • Avoid overly tight filters that restrict air movement and strain HVAC systems.
  • Do not skip maintenance or allow dirty filters to collapse.
  • Portable air cleaners or indoor plants alone do not protect against all indoor air pollutants. A well-chosen, maintained air filter helps improve indoor air quality and overall comfort.

Ventilation Tips to Improve Indoor Air Quality at Home

Proper ventilation improves indoor air quality while keeping energy use low.

Natural Ventilation vs. Mechanical Ventilation Explained

  • Open windows during clear outdoor air quality days to bring outdoor air and lower indoor air pollutants.
  • Close them during humidity or pollen spikes to avoid poor indoor air quality.
  • Run kitchen and bath fans after using hot water to reduce excess moisture and volatile organic compounds.
  • Portable air cleaners can help but do not provide complete protection. Balanced airflow keeps indoor air fresh and comfortable.

How ERV and HRV Improve Indoor Air Quality

  • Energy Recovery Ventilator (ERV) and Heat Recovery Ventilator (HRV) systems exchange stale air for fresh air while conserving energy and controlling humidity.
  • Add High-Efficiency Particulate Air (HEPA) filters or air cleaners to clean outdoor air coming indoors.
  • Adjust ventilation rate seasonally to improve indoor air quality and support air conditioning efficiency.

Best Practices for Duct Integrity

  • Seal and insulate ducts to maintain air flow and HVAC efficiency.
  • Check for leaks, poor air movement, or debris near outdoor air intakes. Clean, sealed ducts keep good air quality and protect your system year-round.

Best Indoor Humidity Range for Comfort and Air Quality

Keeping humidity between 30–50% helps improve indoor air quality at home and maintain comfort.

Humidity Control: Dehumidifiers and Humidifiers Explained

  • Dehumidify: use cooling systems or dehumidifiers in muggy summers to reduce excess moisture, mold spores, and indoor air pollutants.
  • Humidify: during dry winters, add moisture to reduce dust mites and improve air quality.
  • Comfort: balanced humidity lowers allergens, prevents poor indoor air quality, and keeps air conditioning systems efficient. Proper humidity control reduces indoor air pollution and supports clean, healthy indoor air.

IAQ Sensors and Smart Thermostats for Cleaner, Safer Air

  • Monitor humidity, temperature, and indoor pollutant levels with IAQ sensors.
  • Automate dehumidifiers or humidifiers to hold the 30–50% range.
  • Pair smart controls with air cleaners, HEPA filters, and mechanical systems for better ventilation and air cleaning. Maintaining this range protects indoor air quality, limits health risks, and improves HVAC efficiency year-round.

Source Control Strategies for Cleaner Indoor Air

Simple habits can greatly improve indoor air quality at home and limit outdoor air pollution from entering.

Tips to Keep Dust, Pollen, and Allergens Out

  • Place entry mats, remove shoes, and groom pets to reduce dust mites and animal dander.
  • Vacuum and dust often; replace air filters to maintain clean air.
  • During high pollen or poor outdoor air quality, close windows and run air conditioning on auto with good air filters. These habits protect indoor air and reduce indoor air pollutants.

Low-VOC Solutions for a Healthier Home Environment

  • Choose low-VOC (Volatile Organic Compounds) paints, cleaners, and furnishings to cut volatile organic compounds.
  • Use natural ventilation or mechanical systems to bring outdoor air during home projects.
  • Run portable air cleaners with HEPA filters for added air cleaning. Low-VOC materials improve indoor air and reduce health risks.

Room-Specific Indoor Air Quality Solutions

  • Bedrooms: use allergen covers, wash bedding hot, and use an air purifier.
  • Kitchens: use a vent hood to capture smoke and avoid tobacco smoke.
  • Basements: fix leaks and dehumidify to prevent mold and poor air flow. Source control limits indoor air pollution and supports good air quality throughout your home.
