Winter Air Quality Tips: Keep Your Minnesota Home Fresh and Healthy

How to Keep Your Home’s Air Quality Fresh in Winter
When winter arrives in Minnesota, we spend more time indoors to escape the freezing temperatures. However, the closed windows and sealed doors that keep us warm can also trap pollutants and stale air inside. Maintaining good indoor air quality (IAQ) during the winter months is essential for your family’s comfort and health. Here’s how you can keep your home’s air fresh and clean all season long.

1. Replace Your HVAC Filters Regularly
Your HVAC filter plays a vital role in trapping dust, allergens, and other pollutants. During winter, when your heating system runs more frequently, filters can clog faster.

• Replace or clean your filter every 1-3 months.
• Use high-quality HEPA filters for better filtration.

A clean filter ensures proper airflow and reduces the number of airborne contaminants in your home.

2. Use a Humidifier
Winter air is notoriously dry, and running your furnace can worsen the problem. Low humidity can lead to:

• Dry skin and irritated respiratory systems.
• Increased spread of viruses due to dry nasal passages.

A humidifier adds moisture to the air, improving comfort and reducing the risk of health issues. Aim to keep indoor humidity levels between 30-50%.

3. Improve Ventilation
Proper ventilation is key to maintaining fresh air inside your home:

• Crack a window briefly to allow fresh air in, even on cold days.
• Use exhaust fans in kitchens and bathrooms to remove moisture and odors.
• Consider installing a heat recovery ventilator (HRV), which exchanges stale indoor air with fresh outdoor air while retaining heat.

4. Keep Your Home Clean
Dust, pet dander, and other pollutants can accumulate quickly in winter. Regular cleaning helps reduce airborne irritants:

• Vacuum carpets and rugs with a HEPA filter vacuum.
• Wash bedding and curtains to remove dust mites.
• Dust surfaces frequently with a damp cloth to trap particles instead of spreading them.

5. Avoid Chemical Pollutants
Many household products release volatile organic compounds (VOCs) that can affect indoor air quality. To minimize exposure:

• Use natural cleaning products or those labeled as low-VOC.
• Avoid aerosol sprays.
• Store paint, solvents, and other chemicals in a garage or shed, away from living spaces.

6. Add Indoor Plants
Certain houseplants can help purify the air by removing toxins and releasing oxygen. Popular choices include:

• Spider plants
• Peace lilies
• Boston ferns

Note: If you have pets, ensure the plants you choose are non-toxic to animals.

7. Schedule Regular HVAC Maintenance
Your HVAC system needs regular attention to ensure it operates efficiently and doesn’t contribute to poor air quality. Professional maintenance includes:

• Cleaning ductwork to remove dust and debris.
• Inspecting and servicing your furnace or heat pump.
• Checking for mold or mildew in your system.

8. Test for Radon and Carbon Monoxide
Winter is an important time to test your home for radon and carbon monoxide, as sealed homes can trap these dangerous gases.

• Install carbon monoxide detectors and check their batteries regularly.
• Use a radon test kit or hire a professional to check for radon levels in your home.

Why Winter Air Quality Matters
Poor indoor air quality can cause or worsen respiratory issues, allergies, and overall discomfort. By taking steps to improve air circulation, humidity, and cleanliness, you can create a healthier and more comfortable environment for your family.

Keeping your home’s air quality fresh in winter requires a combination of regular maintenance, smart ventilation, and clean living habits. By following these tips, you can enjoy a warm and healthy home during Minnesota’s coldest months.
