Improve Your Home’s Indoor Air Quality This Season

Most of us don’t think twice about the air inside our homes—until the windows stay closed for months, the dog smell settles in, or every time you touch a light switch you get zapped like you just shuffled across the carpet in wool socks. But according to the EPA, indoor air can be two to five times more polluted than the air outside—and sometimes up to 100 times more. The good news? A healthier home is absolutely within reach with a few smart adjustments.

Start with the Basics: Filters & Airflow

Your furnace filter is the MVP of your IAQ system. Higher MERV filters trap smaller particulates, but they also fill up faster—especially in homes with pets. For most 1″ filters, MERV 8 or below works best. For 4″ filters, MERV 10 is usually the sweet spot. No matter the rating, consistent filter changes are essential.

Switching your thermostat fan to ON can also help move and filter air more consistently. Just keep in mind that more airflow = more frequent filter changes.

If your home has an air exchanger (HRV or ERV), make sure it’s doing its job. These systems pull in fresh outdoor air while exhausting stale indoor air, removing pollutants and reducing odors—like a controlled, energy-efficient cross-breeze during the winter months.

Humidity Matters

Minnesota winters are famously dry. Cold air sneaks in, humidity drops, and suddenly everyone in the house has dry hands, sore throats, and enough static to power a science fair project. A whole-home humidifier adds moisture directly into the duct system, helping balance the air throughout your home. Just match the control setting to outdoor temperatures and adjust as conditions change.

Upgrade Your IAQ Tools

If you’re ready to take your indoor air quality further, consider additions like:

• UV lights to neutralize airborne viruses and bacteria
• Electronic air cleaners for advanced filtration
• Ionizing air purifiers that help particles clump together so filters can capture them more effectively

These devices treat the air that passes through your ductwork, so good airflow is key.

Maintenance Makes a Difference

Regular seasonal habits go a long way: vacuum your air exchanger, clean outdoor intake/exhaust vents, flush the humidifier drain line, replace water panels, and check all detectors and thermostat settings.
