Top 10 Ways to Improve Indoor Air Quality at Home
As we spend more time indoors—especially as we get older—the quality of the air inside our homes becomes more important than ever. Indoor Air Quality can directly impact our comfort, respiratory health, sleep, and overall well-being. Poor indoor air can trigger allergies, worsen conditions like asthma or COPD, and even cause fatigue or brain fog. The good news? You can take simple, effective steps to improve the air you breathe and create a healthier living space.
Whether you’re living in a cozy apartment or a sprawling house, these top 10 ways to improve Indoor Air Quality will help you breathe easier, feel better, and stay healthier—especially for those of us in our golden years.
1. Ventilate Your Home Regularly
Opening windows and doors for even a short period each day can make a world of difference. Fresh air helps push out stale, polluted indoor air and replaces it with oxygen-rich outdoor air. If weather or outdoor pollution levels don’t allow for this, consider using a ventilator or air exchange system.
Tip for Seniors: Try opening windows during mid-morning hours when outdoor air quality is usually best. Use window screens to keep insects out while letting clean air in.
2. Use an Air Purifier with a HEPA Filter
High-efficiency particulate air (HEPA) filters are designed to trap 99.97% of particles, including dust, pet dander, mold spores, and even smoke. A quality air purifier can drastically reduce allergens and pollutants, especially in rooms where you spend the most time.
Place purifiers in your bedroom and living room first. If you have pets, opt for models designed to handle dander and hair. Many modern units are quiet and energy-efficient, making them ideal for senior households.
3. Control Humidity Levels
Excess moisture in the air can lead to mold and mildew, which are major contributors to poor Indoor Air Quality. On the other hand, air that’s too dry can irritate your nose, throat, and skin. The ideal indoor humidity level is between 30% and 50%.
Use a digital hygrometer to monitor humidity and install a humidifier or dehumidifier as needed. Bathrooms, basements, and kitchens are common trouble spots, so be extra vigilant there.
4. Keep Your Home Clean (Especially Floors and Upholstery)
Dust mites, pollen, pet hair, and other allergens tend to settle in carpets, curtains, and upholstery. Vacuuming with a HEPA-equipped vacuum cleaner at least twice a week helps trap and eliminate these irritants.
Consider switching to hard flooring if vacuuming becomes physically difficult. Wash rugs, drapes, and bedding regularly, and use a damp cloth to dust surfaces instead of dry dusting, which can send particles into the air.
5. Avoid Scented Products and Aerosols
It’s tempting to use air fresheners, scented candles, or spray cleaners to keep your home smelling nice, but many of these products release volatile organic compounds (VOCs). These invisible chemicals can cause headaches, dizziness, or respiratory irritation.
Instead, opt for natural alternatives like baking soda, vinegar-based cleaners, or essential oil diffusers with proper ventilation. Unscented, non-toxic cleaning products are widely available and a safer option for seniors with sensitivities.
6. Change HVAC and Air Filters Regularly
Your home’s heating and cooling systems circulate air throughout the house. When filters become clogged with dust and debris, they can’t effectively trap pollutants—and may even spread them. Dirty filters also reduce system efficiency, which can increase your energy bills.
Make it a habit to check filters monthly and replace them every 60 to 90 days, or as recommended by the manufacturer. If you’re unsure how to do this, ask a family member or HVAC professional to help.
7. Eliminate Indoor Smoking
Cigarette smoke is one of the most dangerous pollutants for Indoor Air Quality, and even secondhand smoke contains thousands of harmful chemicals. If someone in your household smokes, ask them to do so outside. Better yet, encourage them to quit for their health—and yours.
Even if no one smokes indoors, thirdhand smoke (residue that lingers on furniture and walls) can remain for years and still impact your health. Deep cleaning or replacing affected materials can help reduce this risk.
8. Add Houseplants That Clean the Air
Certain indoor plants can naturally filter out toxins and improve air quality. Plants like spider plants, peace lilies, and snake plants are not only attractive but also effective air purifiers. They absorb carbon dioxide and release oxygen, creating a healthier environment.
Choose low-maintenance varieties if mobility is a concern, and be sure to research which plants are safe if you have pets. Keep plants free from mold and dust by gently wiping their leaves with a damp cloth occasionally.
9. Keep Kitchen and Bathroom Areas Well-Ventilated
Cooking and showering can release moisture, grease, and odors into the air. Without proper ventilation, these can build up over time and contribute to poor Indoor Air Quality.
Use range hoods when cooking, and turn on exhaust fans during and after showers. If you don’t have exhaust fans, crack open a window or use a portable fan to circulate air. Wipe down moist surfaces to prevent mold and mildew growth.
10. Test for Radon and Carbon Monoxide
Invisible and odorless, radon and carbon monoxide are two of the most dangerous indoor pollutants. Radon is a naturally occurring gas that can seep in through your home’s foundation, while carbon monoxide is produced by burning fuel (from stoves, heaters, or fireplaces).
Install radon detectors and carbon monoxide alarms on every level of your home. These small devices can be lifesavers—literally. If radon levels are high, contact a mitigation professional. For carbon monoxide, ensure your appliances are inspected regularly and functioning properly.
Why Indoor Air Quality Matters More as We Age
As we grow older, our bodies become more sensitive to environmental irritants. Pre-existing conditions such as asthma, heart disease, or COPD can worsen when exposed to poor Indoor Air Quality. Seniors also tend to spend more time indoors, increasing exposure to allergens, VOCs, and mold spores.
Clean indoor air isn’t a luxury—it’s a necessity for healthy aging. Improved air quality has been linked to better sleep, increased cognitive function, and fewer respiratory infections, all of which contribute to a higher quality of life.
Bonus Tips for Seniors Living with Pets
Pets are wonderful companions, especially in our later years. But they can bring dander, fur, and odors into the home. Regular grooming, frequent vacuuming, and using a dedicated air purifier in pet-friendly areas can help minimize their impact on Indoor Air Quality. Consider choosing pet-safe plants and cleaners to protect your furry friend, too.
Frequently Asked Questions (FAQs)
Q: How often should I clean my air purifier?
A: You should check the filter every month and clean or replace it based on the manufacturer’s guidelines—usually every 3 to 6 months.
Q: Are houseplants really effective for cleaning the air?
A: Yes, certain houseplants can remove common indoor toxins. While they’re not a complete solution, they complement other air-quality improvements.
Q: Can poor indoor air cause fatigue or brain fog?
A: Absolutely. Pollutants like carbon monoxide, mold, and VOCs can reduce oxygen levels or irritate your system, leading to fatigue, dizziness, and difficulty concentrating.
Q: What are signs of bad Indoor Air Quality?
A: Common signs include persistent coughing, sneezing, headaches, itchy eyes, moldy smells, or excess dust around vents and furniture.
Q: Should I keep windows open at night?
A: If the outdoor air is clean and it’s safe to do so, yes. Nighttime ventilation can improve sleep quality and regulate indoor humidity.
Q: Are ozone generators safe to use for air cleaning?
A: No, ozone can irritate the lungs and is not recommended by the EPA for improving Indoor Air Quality. Stick with HEPA filters or activated carbon purifiers instead.
Q: Can cooking impact indoor air?
A: Yes, especially if you fry foods or use gas stoves. Always use a range hood or fan to ventilate while cooking.
Q: How do I know if my home has radon?
A: You can purchase a radon test kit or hire a certified radon inspector. It’s especially important if you live in areas where radon levels are known to be high.
Q: What’s the best air purifier for a small apartment?
A: Look for compact units with HEPA filters and good reviews. Some models are designed for rooms under 300 square feet and are perfect for apartments.
Q: How can I protect my lungs indoors during wildfire season?
A: Keep windows closed, run a HEPA air purifier, and avoid using candles or cooking smoky foods. Consider sealing window gaps to reduce smoke intrusion.
