Cleaner Indoor Air Will Make for a Healthier Winter

As temperatures drop and we retreat indoors for the winter, maintaining good indoor air quality becomes crucial for our overall health and well-being. The cold weather often forces us to seal our homes, trapping pollutants and reducing ventilation. In Northern Virginia, this can be particularly problematic due to factors like living in older homes, seasonal allergens, and the use of fireplaces and wood-burning stoves. Fortunately, we have put together some practical steps you can take to improve your indoor air quality and create a healthier environment for you and your family during the cold months ahead.

Effective Winter Ventilation Techniques to Enhance Indoor Air Quality 

Even in colder months, proper ventilation is essential to maintain healthy indoor air. Here are some simple yet effective strategies to introduce fresh air and remove pollutants, even when temperatures drop.

• Run exhaust fans: Your home’s bathroom and kitchen exhaust fans are essential for removing excess moisture and pollutants generated by showering, cooking, and cleaning. 
• Open windows strategically: While it might seem counterintuitive during cold weather, briefly opening your windows for 5-10 minutes a day allows for some air exchange. Try to choose times of the day to do this when the outdoor air quality is at its best, such as early morning or late evening. 
• Utilize cross-ventilation: When the weather is a little warmer, create a cross-breeze by opening windows on opposite sides of your home. You can also use window fans to improve the airflow and refresh your home’s air supply. 

Keep Indoor Air Fresh with Regular Cleaning and Maintenance 

Routine cleaning is key to reducing indoor pollutants and improving your home’s air quality. By controlling dust, allergens, and particles, you’ll create a healthier home environment.

• Vacuum frequently: Vacuum carpets and rugs at least once a week using a vacuum, especially one with a High-Efficiency Particulate Air (HEPA) filter. This type of filter effectively traps fine particles that regular vacuums may just recirculate into your home’s air. 
• Dust with a damp cloth: Using a damp cloth to dust surfaces prevents particles from becoming airborne and redistributing throughout your home. 
• Wash bedding weekly: Washing your bedding, including sheets, blankets, and pillowcases, weekly in hot water will help reduce dust mites and allergens. 
• Maintain or Replace Your Home’s HVAC filters: Your HVAC system's filters are responsible for capturing many airborne particles. Replace them every 1-3 months or more frequently if you have pets or allergies. 

Control Moisture for Healthier Indoor Air Quality

Managing indoor humidity is another key to preventing pollutants in your air, like mold and allergens. Here are some ways to keep moisture in check and create a healthier home environment.

• Monitor humidity levels in your home: Keep indoor humidity between 30-50%, which can be measured using a hygrometer. 
• Use a dehumidifier: With areas in your home that are prone to dampness, such as basements and bathrooms, consider using a dehumidifier to reduce moisture levels. 
• Address water leaks promptly: Repair any pipes or joints that are leaking immediately. This will help prevent mold growth that can get in the air. Plus, it’ll save you from structural damage. 
• Ensure proper drainage: Maintain proper drainage around your home's foundation to prevent water from seeping into your basement. 

Simple Steps to Minimize Indoor Air Pollutants

Implementing some everyday habits and commonly available household products can impact indoor air quality. Here are easy ways to reduce pollutants and create a cleaner, healthier home environment.

• Remove shoes at the door: This prevents outdoor pollutants, such as dirt, pesticides, and pollen, from being tracked into your home. 
• Choose natural cleaning products: Opt for natural cleaning products whenever possible to avoid harsh chemicals and fumes. 
• Avoid smoking indoors: Smoking indoors releases harmful chemicals that can linger even after the cigarette is extinguished. 
• Groom your pets: Regularly grooming your pets helps minimize the pet dander in the air, which is a common allergen. 
• Store chemicals properly: Store paints, solvents, and other chemicals in a well-ventilated area located outside your home, such as a garage or shed. 

Boost Indoor Air Quality with Air-Purifying Solutions

Enhance your home’s air quality with these powerful tools, from purifiers to natural air fresheners and air-purifying plants, for a cleaner, healthier environment.

• Invest in an air purifier: Air purifiers with True HEPA filters are highly effective at capturing a wide range of airborne particles, including allergens, dust, and mold spores. Look for units with features like multiple filtration stages, a CADR (Clean Air Delivery Rate) appropriate for your room size, and quiet operation. 
• Introduce air-purifying plants: Certain indoor plants are known for their air-cleaning properties. Species like spider plants, snake plants, peace lilies, and bamboo palms can remove a variety of pollutants, including formaldehyde, benzene, and trichloroethylene.
• Consider natural air fresheners: Ditch chemical air fresheners in favor of natural alternatives like essential oil diffusers, beeswax candles, activated charcoal bags, or simmering herbs and citrus on the stovetop. 

Essential Monitoring and Maintenance for a Healthy Home Environment

Stay proactive with regular checks on key areas, from fuel-burning appliances to mold prevention, ensuring your indoor air quality remains safe and healthy year-round.

• Check fuel-burning appliances: Ensure proper ventilation of fuel-burning appliances, such as fireplaces, furnaces, and water heaters, to prevent the buildup of carbon monoxide. Regular maintenance can save your air and improve efficiency.  
• Test for radon: Radon is a naturally occurring radioactive gas that can seep into homes from the ground. Have your home tested for radon and take steps to mitigate it if levels are high. 
• Be vigilant for mold: Watch for signs of mold growth, such as discoloration, musty odors, or visible spores. Address any mold issues promptly. 
• Maintain carbon monoxide detectors: Check and test your carbon monoxide detectors regularly to ensure they are functioning properly.
