As winter sets in, we close our windows, turn up the heat, and settle into a cozy indoor environment. However, this season also brings challenges for indoor air quality (IAQ). With homes sealed against the cold, dust, allergens, and pollutants can build up, leading to stale, dry, and sometimes unhealthy indoor air. Fortunately, there are several ways to keep your home’s air fresh and clean all season long.
Here’s a guide to improving indoor air quality during winter, helping you breathe easier and enjoy healthier heating.
1. Regularly Replace HVAC Filters
One of the simplest and most effective ways to improve IAQ is by regularly replacing your HVAC filters. During winter, heating systems are in constant use, and filters quickly capture dust, pet dander, and other airborne particles. Over time, a clogged filter reduces airflow and causes your HVAC system to work harder, decreasing its efficiency and increasing utility costs.
How often should you change filters? Generally, replace your filter every 1-3 months, depending on your household’s needs. Homes with pets or individuals with allergies may benefit from monthly replacements.
2. Use a Humidifier to Combat Dry Air
Winter air tends to be dry, and heating systems can worsen this dryness, leading to dry skin, sore throats, and respiratory discomfort. A humidifier helps add moisture back into the air, improving comfort and reducing irritants that can worsen allergy or asthma symptoms.
Tip: Aim for a humidity level between 30-50% for a comfortable balance. Many HVAC systems can be equipped with whole-home humidifiers, but portable units can also be effective in individual rooms.
3. Clean and Inspect Air Ducts
Dust, mold, and other contaminants can accumulate in your HVAC ductwork, especially in homes where ducts haven’t been cleaned in a while. These particles can recirculate through your heating system, affecting indoor air quality.
Schedule a Professional Cleaning: Consider a professional duct cleaning every few years or if you notice excessive dust around vents or experience frequent respiratory issues. This will not only improve air quality but can also enhance the efficiency of your heating system.
4. Consider an Air Purifier
Air purifiers help capture and neutralize pollutants, allergens, and even bacteria in the air, which can be especially helpful during winter when airflow is limited. There are a variety of air purifiers available, from portable units to whole-home systems.
UV Light Purifiers: Some HVAC systems can be equipped with UV light purifiers, which help kill bacteria, viruses, and mold spores as air passes through. This is a proactive solution for those particularly concerned about germs and allergens in winter.
5. Ventilate When Possible
It may seem counterintuitive to open windows during winter, but brief ventilation can significantly improve IAQ by introducing fresh air into your home and allowing trapped pollutants to escape.
How to Ventilate Safely: Choose milder winter days and open a window or door briefly, even for just a few minutes. This quick exchange of air can refresh your home without losing too much heat.
6. Schedule Routine HVAC Maintenance
Routine maintenance for your heating system is essential for efficient operation and healthier indoor air. A professional technician can check for issues that may affect IAQ, such as dirty coils, clogged condensate drains, or leaks in ductwork.
Why It Matters: Maintenance keeps your system clean, efficient, and capable of properly filtering out pollutants. Van Bremen’s Heat & Air offers seasonal maintenance checks to keep your system running smoothly, reducing indoor pollutants and helping you maintain a healthy home.
7. Opt for Natural Cleaning Solutions
Many common cleaning products release volatile organic compounds (VOCs), which can linger in indoor air and contribute to poor IAQ. During winter, when airflow is reduced, these chemicals can build up faster.
Healthier Alternatives: Use natural or fragrance-free cleaning products to limit VOC exposure. Vinegar, baking soda, and mild soaps are effective and safer options for keeping your home clean without compromising indoor air quality.
Why Indoor Air Quality Matters in Winter
During winter, we often spend up to 90% of our time indoors, making air quality a crucial factor for our overall health and comfort. Poor IAQ can exacerbate allergies, asthma, and even cause headaches or fatigue. By following these tips and investing in the right equipment and maintenance, you can create a healthier, more comfortable environment for you and your family throughout the season.
