Simple Ways to Improve Your Home’s Indoor Air Quality

The air inside our homes can often be more polluted than the air outside. From dust and pet dander to volatile organic compounds (VOCs) from cleaning products, poor indoor air quality can affect your comfort, sleep, and overall health. The good news? You don’t need a complete home overhaul to make a difference.

Here are seven simple and effective ways to improve your home’s indoor air quality and create a healthier living environment for you and your family.


1. Increase Ventilation with Fresh Air

One of the easiest and most effective ways to dilute indoor pollutants is to introduce fresh air from the outdoors.

  • Open Windows and Doors: On days with good air quality and pleasant weather, open windows and doors for at least 15-20 minutes to create cross-ventilation.
  • Use Exhaust Fans: Run kitchen and bathroom exhaust fans regularly to remove moisture, cooking fumes, and other pollutants directly outside.
  • Consider an Air Exchanger: For homes in very cold or hot climates, or for those with allergies, an energy recovery ventilator (ERV) or heat recovery ventilator (HRV) can bring in fresh air without losing energy.

2. Control the Sources of Pollutants

Preventing pollutants from entering your home in the first place is a powerful strategy. Pay attention to what you bring inside.

  • Choose Low-VOC Products: When painting or buying new furniture, look for products labeled “low-VOC” or “zero-VOC” to reduce chemical fumes.
  • Use Natural Cleaners: Opt for natural cleaning solutions like vinegar, baking soda, or commercially available non-toxic cleaners.
  • Store Chemicals Safely: Keep paints, solvents, and harsh chemicals in a garage or shed, away from your main living space.

3. Invest in a High-Quality Air Purifier

An air purifier is a fantastic tool for continuously cleaning the air, especially for those with allergies or asthma.

  • Look for a HEPA Filter: A True HEPA (High-Efficiency Particulate Air) filter is the gold standard. It can capture at least 99.97% of airborne particles, including dust, pollen, and pet dander.
  • Consider an Activated Carbon Filter: For odors, smoke, and VOCs, choose a purifier that also includes an activated carbon filter.
  • Place it Strategically: Put the air purifier in the room where you spend the most time, like your bedroom or living room.

4. Keep Your Home Clean and Dust-Free

Dust is a major carrier of allergens and other irritants. A regular cleaning schedule can significantly reduce what’s floating in the air.

  • Vacuum with a HEPA Filter: Standard vacuums can kick dust back into the air. A vacuum with a HEPA filter traps fine particles instead of releasing them.
  • Dust with a Damp Cloth: Dry dusting just moves particles around. Wiping surfaces with a damp or microfiber cloth captures dust effectively.
  • Wash Bedding Regularly: Wash sheets, blankets, and pillowcases in hot water weekly to kill dust mites and remove allergens.

5. Harness the Power of Indoor Plants

Houseplants are natural air purifiers that can add beauty to your home while cleaning the air.

  • Choose the Right Plants: Some plants are particularly effective at filtering out common toxins. Good options include the Spider PlantSnake PlantPeace Lily, and English Ivy.
  • Note: While plants help, you’d need a significant number to have the same impact as a mechanical air purifier. Think of them as a beautiful supplement to your other efforts.

6. Maintain Optimal Humidity Levels

Too much moisture can lead to mold and mildew growth, which are major air quality concerns. Too little can cause dry skin and respiratory irritation.

  • Use a Dehumidifier or Humidifier: Aim to keep your home’s humidity between 30% and 50%. A dehumidifier is great for damp basements, while a humidifier can help in dry, winter months.
  • Fix Leaks Promptly: Repair any leaky pipes or faucets to prevent mold from taking hold.
  • Ventilate Properly: Use exhaust fans in high-moisture areas like bathrooms and kitchens.

7. Change Your HVAC Filters Regularly

Your home’s heating and air conditioning system has filters that are designed to trap dust and debris. For them to work effectively, they need to be clean.

  • Check Filters Monthly: At least once a month, check your HVAC filter.
  • Change Every 2-3 Months: Most standard filters should be replaced every 90 days. If you have pets or allergies, consider changing them more often.
  • Use High-MERV Filters: A filter with a higher MERV (Minimum Efficiency Reporting Value) rating can capture smaller particles, but check your system’s manual to ensure it’s compatible.
  • Duct Inspection and Maintenance:  Remember to create a schedule to have your air vents and ducts to be checked for mildew, mold or just heavy dust buildup
