What You Don’t See Can Affect You When It Comes To Winter Air Quality

When winter settles in, most of us do the same thing: shut the windows, seal the drafts, and crank the heat. It’s great for comfort and energy efficiency, but not always great for the air we breathe. With homes closed up tight for months at a time, indoor air quality can quietly take a hit, leading to discomfort and even health concerns.

The good news? A few smart habits and simple upgrades can make a noticeable difference.

Why Indoor Air Quality Suffers in Winter

Cold weather means less fresh air circulating through your home. At the same time, heating systems kick into high gear, stirring up dust and other particles that might otherwise stay settled. Common indoor pollutants during winter include dust, pet dander, mold spores, and volatile organic compounds (VOCs) released from cleaning products, paints, and furnishings.

When these pollutants build up, people may experience headaches, fatigue, sinus irritation, or respiratory issues - symptoms often lumped under the term “sick building syndrome.” If you’re feeling off all winter, your indoor air might be part of the problem.

Practical Ways to Improve Winter Air Quality

Let Fresh Air In, Yes, Even in Winter

You don’t need to leave windows wide open. Short bursts of fresh air, just a few minutes at a time, can help flush out stale indoor air. Using kitchen and bathroom exhaust fans also helps remove moisture and airborne contaminants right at the source.

Keep Humidity in the Sweet Spot

Indoor humidity should hover around 40–50%. Too much moisture encourages mold growth, while air that’s too dry can irritate your nose, throat, and skin. A humidifier or dehumidifier can help keep things balanced, especially in older homes.

Stay on Top of HVAC Maintenance

Your heating system keeps you warm and moves air throughout your home. Change filters every three months and schedule annual maintenance to keep things running efficiently. Dirty filters and neglected systems can spread dust and allergens instead of trapping them.

Use Air Purifiers Where You Spend the Most Time

A quality air purifier with a HEPA filter can significantly reduce airborne particles like dust, pollen, and pet dander. Units with activated carbon filters also help absorb odors and chemical fumes. Bedrooms and living areas are usually the best places to start.

Add a Few Low-Maintenance Houseplants

Some plants help improve indoor air quality while also making your home feel more alive during the gray winter months. Snake plants, for example, are hardy, low-maintenance, and known for their air-filtering benefits.

Choose Cleaning Products Carefully

Many conventional cleaners release VOCs that linger in indoor air. Switching to natural or low-VOC products can reduce chemical exposure. When stronger products are necessary, proper ventilation is key.

Install and Maintain Gas Detectors

Carbon monoxide and radon are invisible, odorless, and potentially dangerous. Make sure detectors are installed and functioning properly, and test them regularly, especially during heating season.

Keep Dust Under Control

Regular dusting and vacuuming go a long way. Using a vacuum with a HEPA filter prevents allergens from being kicked back into the air while you clean.

Go Easy on Scents

Candles, plug-ins, and air fresheners may smell nice, but many release VOCs. If you use them, do so sparingly and make sure rooms are well ventilated.

Breathe Easier All Winter Long

Winter doesn’t have to mean stale air and stuffy rooms. With a few proactive steps, you can protect your indoor air quality, improve comfort, and create a healthier home environment for everyone under your roof.

Reduce Pollen Exposure

This has been an exceptionally tough allergy season for many people here in Connecticut. With high pollen counts and low rainfall, it feels like we’ve been sniffling and coughing for the best part of the spring. While the end is not quite in sight, there are plenty of things we can do to reduce our exposure. Here are my top ten tips:

1. Keep windows closed - It can be tempting to open up the windows on these gorgeous mornings, but pollen levels are generally the highest in the early hours of the day. 

2. Don’t wear shoes indoors - This is an easy way to bring pollen inside the house. Leave shoes outside or in your mudroom or breezeway to reduce allergen spread.

3. Consider an air purifier - A high-efficiency particulate air (HEPA) filter will help to neutralize pollen, especially in places like the bedroom where allergies may interfere with your sleep. 

4. Shower at night - Most of us enjoy a hot shower in the morning, but if you’re outside during the day, pollen is going to stick to your clothes and hair. Consider switching up your routine during peak allergy times.

5. Keep dirty clothes in a closed bin - Wash clothes frequently and consider using a laundry basket with a lid on it, especially if you keep it in your bedroom. 

6. Dry clothes indoors - if you hang your clothes on a line to dry, they are going to attract a lot of pollen. Now is the time to use an indoor drying rack.

7. Vacuum often - pollen can creep indoors easily, even if you’re removing shoes and taking other precautions. Consider vacuuming more frequently and be sure that your vacuum cleaner has a HEPA filter. 

8. Know what aggravates you - allergy season is long and people are affected by different types of exposures. Right now, tree pollen counts are very high and ragweed is very low. If you know what you’re sensitive to, you can be better prepared.

9. Plan ahead - Online apps and websites like Accuweather can help you plan your activities based on your allergy triggers. This is also very helpful when you’re traveling to another region or area.

10. Try saline spray - if you find yourself walking around with a blocked airway, a simple saline spray is a great way to keep the nasal passages clear.

While some people may experience mild allergies, others will be dealing with symptoms that are much more severe. While these ideas will help to reduce pollen exposure, it’s a good idea to consult with a professional healthcare provider for the best advice and treatment options.
