Winter is the season of sealed windows, cozy heating, and unfortunately, dirtier indoor air. When temperatures drop, homes are closed up tight to keep the cold out, which allows dust, allergens, and other airborne contaminants to build up. For homeowners concerned about indoor air quality in Cambridge, MA, winter is a critical time to pay attention to what you’re breathing and take steps to keep your home healthier and more comfortable.
Why Indoor Air Gets Dustier in Winter
During winter, your HVAC system runs more frequently, circulating air—and everything in it—throughout your home. Because fresh outdoor air isn’t coming in through open windows, dust, pet dander, pollen, and other particles have nowhere to escape. Everyday activities like cooking, cleaning, and even walking around kick these contaminants into the air. Dry winter air can make the problem worse by allowing particles to stay airborne longer, increasing the amount of dust you see on surfaces and breathe into your lungs.
Don’t Forget to Change Your HVAC Filters
One of the simplest and most effective ways to protect your indoor air quality is changing your HVAC filter regularly. A clogged or dirty filter can’t trap particles effectively, allowing dust and allergens to circulate back into your living spaces. In winter, filters often need to be checked and replaced more frequently due to increased system use.
Upgrading to a higher-quality filter can also improve performance—but only if it’s compatible with your system. Our team can help you choose the right filter to balance air cleanliness, airflow, and system efficiency.
Signs Your Indoor Air Quality May Be Affecting Your Health
Poor indoor air quality often shows up in subtle but persistent ways. If you or your family notice more frequent headaches, dry or irritated eyes, coughing, congestion, or worsening allergy or asthma symptoms during winter, your air may be part of the problem. Excessively dry air can also cause itchy skin, static electricity, and cracked wood furnishings, while stale air can make your home feel stuffy and uncomfortable even when the temperature is right.
IAQ Solutions That Make a Real Difference
For long-term improvement, whole-home indoor air quality solutions are far more effective than portable devices.
