5 Simple Ways to Improve Indoor Air Quality Without Breaking the Bank

Home | Blog | Published on July 28th, 2025

Indoor air quality (IAQ) is an essential aspect of a healthy home environment. Poor air quality can trigger allergies, respiratory problems, and general discomfort. The good news is you don’t need expensive equipment or major renovations to breathe cleaner, fresher air. 

With a few simple and affordable steps, you can significantly improve your home’s air quality without breaking the bank. Here are five easy ways to get started.

1. Change or Clean Your Air Filters Regularly

One of the most effective and low-cost ways to improve indoor air quality is by maintaining your HVAC system’s air filters. Filters trap dust, pollen, pet dander, and other airborne particles that would otherwise circulate through your home.

  • Replace disposable filters every 30 to 90 days, depending on the type and how heavily your system runs.
  • Consider upgrading to higher-quality pleated filters that capture smaller particles more effectively.
  • If you have a washable filter, clean it regularly according to the manufacturer’s instructions.
  • Dirty or clogged filters reduce airflow and allow contaminants to build up, which harms your system’s efficiency and your indoor air.

2. Increase Ventilation by Opening Windows and Using Fans

Bringing fresh air into your home is a natural and cost-free way to reduce indoor pollutants. Whenever weather permits, open windows and doors to create cross-ventilation and flush out stale air.

  • Aim to ventilate your home for at least 10-15 minutes daily.
  • Use ceiling fans or portable fans to help circulate air and improve airflow.
  • Use exhaust fans in kitchens and bathrooms to remove moisture and odors quickly.

Proper ventilation dilutes indoor pollutants and helps keep humidity at healthy levels.

3. Control Humidity Levels

Excess humidity can create a breeding ground for mold, mildew, and dust mites, all of which worsen indoor air quality. Maintaining the right humidity level keeps your home healthier and more comfortable.

  • Use an inexpensive hygrometer to monitor indoor humidity; the ideal range is between 30% and 50%.
  • Use a dehumidifier in damp areas such as basements or bathrooms to reduce moisture.
  • Fix leaks and improve drainage around your home to prevent moisture buildup.

Balancing humidity prevents allergens and protects your home’s structure from moisture damage.

4. Keep Your Home Clean and Dust-Free

Dust, pet dander, and allergens accumulate quickly and can easily become airborne, worsening IAQ.

  • Vacuum carpets and rugs regularly with a vacuum that has a HEPA filter to trap fine particles.
  • Dust surfaces with a damp cloth to avoid sending particles into the air.
  • Wash bedding, curtains, and upholstery often in hot water to remove allergens and dust mites.
  • Declutter to reduce places where dust can accumulate.

Regular cleaning helps reduce airborne irritants and allergens, improving breathing comfort.

5. Choose Non-Toxic Cleaning and Household Products

  • Many conventional cleaning products, paints, and air fresheners release volatile organic compounds (VOCs) and other pollutants that degrade air quality.
  • Opt for natural or low-VOC cleaning products and paints.
  • Avoid synthetic fragrances and aerosols that can irritate the respiratory system.
  • Store chemicals and solvents in well-ventilated areas away from living spaces.
  • Using safer products reduces harmful chemicals in your indoor environment without added costs.
