6 Ways to Improve Indoor Air This Winter

February 14th, 2026

Winter often means closed windows, longer heater run times, and drier air inside our homes. While that helps keep us warm, it can also lead to stuffy rooms, increased dust, and air that just doesn't feel as comfortable.

The good news? Improving your indoor air quality during winter doesn't have to be complicated. A few simple steps can make a noticeable difference in how your home feels and how you feel in it.

Here are six easy ways to improve indoor air quality this winter.


1. Change Your HVAC Air Filter Regularly

Your air filter works harder in winter because your heating system runs more often.

A clean filter helps:

  • Trap dust and allergens

  • Improve airflow

  • Keep air circulating evenly

Most homes benefit from changing filters every 1-3 months during the heating season. If your home has pets or allergies, checking it more often is a smart move.


2. Keep Vents and Returns Clear

Blocked vents can trap dust and reduce airflow, which affects both comfort and air quality.

Take a few minutes to:

  • Move furniture away from vents

  • Remove rugs or décor covering floor returns

  • Lightly dust vent covers

Clear airflow allows your HVAC system to filter and circulate air more effectively.


3. Add Moisture Back Into Dry Winter Air

Winter air tends to be dry, which can cause:

  • Dry skin and irritated sinuses

  • Scratchy throats

  • Static electricity

Using a humidifier even a portable one can help balance moisture levels and make the air feel more comfortable to breathe.


4. Use Bathroom and Kitchen Exhaust Fans

Exhaust fans help remove moisture, odors, and airborne particles from your home.

Run them:

  • During and after showers

  • While cooking

  • For a few minutes afterward

This simple habit helps keep air fresher and reduces excess humidity in winter.


5. Let Fresh Air In When Conditions Allow

On mild winter days, opening windows for just 5 minutes can help refresh indoor air.

This quick exchange:

  • Reduces stale air

  • Lowers indoor pollutants

  • Helps your home feel less stuffy

It works best when outdoor air quality is good and pollen levels are low.


6. Schedule HVAC Maintenance for Cleaner Air

Your heating system plays a major role in indoor air quality.

Routine maintenance helps:

  • Improve airflow

  • Reduce dust circulation

  • Keep components clean

  • Support healthier air overall

Even if your heater seems to be running fine, a seasonal checkup can make a difference in comfort and air quality.


A Neighborly Reminder for Winter Comfort

Clean indoor air isn't about perfection it's about small, thoughtful steps that help your home feel healthier and more comfortable during the winter months.

If your home still feels dusty, dry, or uncomfortable, your HVAC system may need a little extra care.
