Understanding Indoor Air Quality During Winter

As winter tightens its grip, homeowners often seal their residences to keep the cold at bay. While this practice conserves heat, it can inadvertently compromise indoor air quality, leading to discomfort and potential health issues. Understanding the challenges and implementing effective strategies can ensure your home's air remains fresh and healthy throughout the colder months.

Understanding the Winter Air Quality Challenge

During winter, increased use of heating systems and reduced ventilation can lead to a buildup of indoor pollutants. Common culprits include dust mites, pet dander, mold spores, and volatile organic compounds (VOCs) emitted from household products. Exposure to these pollutants may cause symptoms like headaches, dizziness, and respiratory issues, often referred to as "sick building syndrome."

Effective Strategies to Enhance Indoor Air Quality

1. Regular Ventilation: Even in cold weather, it's essential to allow fresh air to circulate. Briefly opening windows or doors can help disperse indoor pollutants. Utilizing exhaust fans in kitchens and bathrooms further aids in expelling contaminants. 

2. Maintain Optimal Humidity Levels: Aim to keep indoor humidity around 50%. Excess moisture fosters mold growth, while overly dry air can irritate respiratory passages. Using humidifiers or dehumidifiers as needed can help maintain this balance.

3. Regular HVAC Maintenance: Ensure your heating system is serviced annually. Clean or replace filters every 1-3 months to prevent dust and allergen accumulation. Consider having your air ducts inspected and cleaned to remove any built-up debris that could circulate throughout your home.

4. Consider Using Air Purifiers: Air purifiers can be a powerful tool in maintaining indoor air quality during winter. Look for models equipped with HEPA (High-Efficiency Particulate Air) filters, which are designed to capture small particles like dust, pollen, and pet dander. Many purifiers also include activated carbon filters to remove odors and VOCs from the air. Placing a purifier in frequently used spaces, like the living room or bedroom, can significantly reduce airborne pollutants and help create a healthier home environment.

5. Incorporate Indoor Plants: Certain houseplants can naturally purify indoor air by absorbing toxins and releasing oxygen. Plants like sansevieria (snake plant) are known for their air-cleaning properties and can be a beneficial addition to your home with very low maintenance needs.

6. Use Natural Cleaning Products: Traditional cleaning agents can emit VOCs, degrading air quality. Opt for natural or eco-friendly cleaners to minimize chemical exposure. Additionally, store chemicals safely and ensure proper ventilation when using them.

7. Monitor for Radon and Carbon Monoxide: Install detectors to monitor levels of these colorless, odorless gases. Regularly test and maintain these devices to ensure they function correctly, safeguarding your household from potential hazards.

8. Keep Your Home Clean: Regular dusting and vacuuming can significantly reduce indoor pollutants. Using a vacuum with a HEPA filter ensures that dust and allergens are effectively captured and not redistributed into the air.

9. Be Cautious with Scented Products: Air fresheners and scented candles can emit VOCs. Opt for unscented or naturally scented alternatives, and ensure proper ventilation when using them.

By implementing these strategies, you can maintain a healthy indoor environment during the winter months, ensuring that your home remains comfortable and safe.

Winter Prep Home Maintenance Tasks

With the forecast set to settle into the 40s, it’s time to talk about getting our homes ready for the cold before the thermometer drops below freezing. After all, there is nothing worse than not being ready when the first proper snowfall comes our way. So without further ado, here are my top five tips for pre-winter preparation at home:

Take a picture of your roof.

We’ll start with an easy one. Go outside and snap a photo of your roof from each direction. Wondering why? When we get a massive snowfall, I usually recommend that people get their roofs shoveled. Removing the snow helps to reduce the risk of leaks and other damage to your home. But when the snow is very deep, it’s impossible to see the pipes, skylights, and other parts and pieces that stick up out of the roof. Keeping a picture of the clean surface is a great way to minimize the probability of an accident when you’re trying to prevent damage in the first place.

Stake the driveway.

Speaking of damage prevention, stop by the local hardware store and get some property markers. They are generally made of wood or metal and are sometimes painted in a fluorescent color. Use the markers to create an outline around your driveway. Just like your roof, when a blanket of snow hits, it’s impossible for a removalist to see where the driveway ends and where your lawn begins. Creating that parameter will help the plow truck driver know where to go, which should assist in keeping your curbs and grass intact.

Give the furnace a checkup.

Don’t wait until you really need heat to make sure that everything is in working order. Clean or replace your HVAC filters and check the temperature gauge to make sure you can power up and down with no problems. If you haven’t already, now is definitely time to remove those window A/C units and check and clean those filters too. While you’re at it, make sure your carbon monoxide detectors are working and change the batteries if necessary.

Seal up the air holes.

I get calls all winter long from people who are wondering why their house is so drafty. If you have an attic hatch, install an insulated box to prevent the cold air from coming down into your living space. Check all your windows and doors for gaps and use weatherstripping, foam, or insulation to seal them tight. If you have a fireplace that you don’t use, get that covered too. Any passageways from the inside to the outside can act as wind tunnels when the frigid winter air comes calling.

Clean those gutters.

If your gutters are full of autumn leaves and debris, it will prevent winter water from flowing off the roof and down away from the foundation. If water has nowhere to go, it will refreeze in your gutters and at the base of your roof, resulting in dangerous ice dams and potential leaks. If you don’t want to do this dirty job yourself, schedule a pro to handle it for you. It will be worth it.

If you do just these five things, you’ll be in much better shape when the wicked weather decides to settle in. Plus it’s much more pleasant to get these jobs out of the way before it’s too cold and snowy to bother. Good luck and as always, don’t be afraid to reach out if you need help or advice. Happy Thanksgiving!
