5 Tips To Improve Your Indoor Air Quality This Fall

As the crisp air of fall sets in here in Wisconsin, many of us spend more time indoors to stay warm and cozy.

However, with sealed windows and less fresh air circulation, fall can be one of the worst times of the year for indoor air quality. In fact, poor air quality in your home can contribute to heightened allergies, asthma, and even long-term health issues.

The good news? A few simple steps can go a long way in making sure your indoor environment is clean, fresh, and healthy all season long.

Here are five practical tips to help improve your indoor air quality this autumn:

Furnace Filter Installation/Replacement

1. Change Your HVAC System’s Air Filters

One of the easiest and most effective ways to improve indoor air quality is to change your HVAC system’s air filters regularly. We suggest that you do this every 1 to 3 months (once a month or so if you have pets or individuals with asthma living in your home).

Dirty filters not only restrict airflow but also allow dust, pollen, and other contaminants to circulate through your home. You should consider using high-efficiency particulate air (HEPA) filters for even better filtration.

Here is how often you should change your HVAC filters.


2. Keep Humidity Levels in Check

Fall weather often brings fluctuating humidity levels. Too much humidity can promote mold growth, while too little can dry out your skin and respiratory tract.

Our suggestion is to use a humidifier or dehumidifier as needed to maintain an ideal indoor humidity level between 30% and 50%. A whole-home humidifier connected to your HVAC system can make this process seamless.

3. Clean Air Ducts and Vents

Your home’s ductwork system is susceptible to accumulating dust, pet dander, mold, and other pollutants over time. As your heating system kicks in during fall, those contaminants can be blown throughout your home.

Professional duct cleaning or sealing helps to ensure cleaner air and better HVAC efficiency.

Also – don’t forget to vacuum your vents and keep them unblocked by furniture or curtains!


Improve Your Indoor Air Quality with House Plants

4. Add Indoor Plants

Another suggestion we have is to add indoor plants to your living space. Certain houseplants act as natural air purifiers.

For example, plants like peace lilies, spider plants, and snake plants can help remove toxins and increase oxygen levels. Just be sure not to overwater them, as excess moisture can lead to mold growth.


5. Invest in an Air Purification System

For optimal indoor air quality, consider installing a whole-home air purifier or upgrading your HVAC system with air-cleaning technology.

Options like UV light systems, electronic air cleaners, and energy recovery ventilators (ERVs) can dramatically reduce airborne pollutants and enhance ventilation.
