7 Powerful Indoor Air Quality Tips for a Healthier Home
When cold and flu season arrives, families tend to spend more time indoors. That makes indoor air quality tips especially useful for creating a cleaner, more comfortable home environment. Good ventilation, proper filtration, humidity control, and air cleaning can all play a role in reducing indoor pollutants and airborne particles.
An air purifier can be helpful, but it should not be viewed as a cure-all. The EPA recommends a combination of source control, ventilation, and supplemental filtration or air cleaning for better indoor air quality.
Here are seven practical ways to prepare your home for the cold and flu season.
1. Use the Right Air Purifier for Your Space
One of the most useful indoor air quality tips is choosing an air cleaner that fits the size of the room where it will be used.
Portable HEPA air cleaners can help reduce airborne particles in a room. Research summarized by the CDC has found that portable air cleaners can reduce particulate matter, although their effectiveness depends on factors such as room size, airflow, and placement.
For whole-home coverage, homeowners may want to explore HVAC-based filtration or whole-home air purification options with a qualified professional.
2. Change Your HVAC Filter Regularly
Your HVAC filter plays an important role in keeping particles from continuously circulating through your home’s air system. Among the simplest indoor air quality tips is checking your filter regularly and replacing it according to the manufacturer’s recommendations.
A dirty filter can restrict airflow and make your HVAC system work harder. The right filter also matters, so avoid installing a filter that your HVAC system is not designed to handle.
If you’re unsure which filter is appropriate, an HVAC professional can help.
3. Improve Ventilation When Conditions Allow
Fresh outdoor air can help dilute indoor pollutants. One of the most important indoor air quality tips is improving ventilation when outdoor weather and air quality make it safe and practical.
Opening windows or doors for fresh air can help, but this isn’t always practical during cold weather or when outdoor pollution or pollen levels are high. The EPA recommends considering outdoor air quality, temperature, humidity, and other conditions before increasing ventilation.
Your HVAC system’s ventilation features can also be evaluated to determine whether your home has adequate air exchange.
4. Keep Indoor Humidity Under Control
Humidity can affect comfort and indoor air conditions. One of the often-overlooked indoor air quality tips is maintaining a reasonable humidity level inside your home.
The EPA recommends keeping indoor humidity below 60%, with an ideal range of approximately 30% to 50%.
Too much moisture can contribute to conditions that support mold growth, while extremely dry air can make your home feel uncomfortable. A humidity monitor can help you keep track of indoor conditions.
5. Keep Your HVAC System Clean and Maintained
Regular HVAC maintenance is another important part of indoor air quality tips because your heating and cooling system continually moves air throughout your home.
During maintenance, a qualified technician can inspect filters, airflow, coils, electrical components, and other parts of the system. Proper maintenance can also help your equipment operate efficiently.
If you notice excessive dust, unusual odors, poor airflow, or inconsistent temperatures, don’t simply assume you need a new air purifier. The underlying HVAC system may need attention.
6. Consider Whole-Home Air Purification
For homeowners who want more comprehensive filtration and air cleaning, a whole-home solution may be worth considering. This is one of the indoor air quality tips that can make sense when a family wants air cleaning integrated with its existing HVAC system.
Whole-home systems are designed to work with central HVAC equipment rather than treating just one room. Garrison & Garrison can help homeowners evaluate options based on their home’s HVAC system, layout, and comfort needs.
An option such as the REME HALO® Whole Home In-Duct Air Purifier may be considered as part of a broader indoor air quality strategy.
Keep in mind that air purification does not eliminate the need for ventilation, cleaning, source control, or other healthy-home practices.
7. Reduce Indoor Sources of Air Pollution
The best indoor air quality tips aren’t always about buying new equipment. Reducing pollutants at their source can be just as important.
Avoid smoking indoors, use kitchen exhaust fans when cooking, control moisture, clean regularly, and choose household products carefully. The EPA identifies indoor sources such as cooking, cleaning products, secondhand smoke, building materials, furnishings, mold, and pollen as contributors to indoor air pollution.
Reducing pollutants at the source, combined with ventilation and filtration, creates a stronger overall approach to cleaner indoor air.
Can an Air Purifier Prevent Colds or the Flu?
This is an important distinction. Air purifiers can reduce certain airborne particles, but they should not be presented as a guarantee against getting a cold or flu.
Instead, think of air cleaning as one layer of protection. CDC guidance supports improving ventilation and using air filtration as part of a broader approach to reducing exposure to respiratory particles indoors.
Good hygiene, staying home when sick, appropriate medical care, and other public health measures remain important during the respiratory virus season.
Frequently Asked Questions
What are the best indoor air quality tips for cold and flu season?
Start with proper HVAC filtration, regular maintenance, appropriate ventilation, humidity control, and source reduction. A properly sized air cleaner can provide another layer of filtration.
Do air purifiers help with viruses?
Some air cleaners can remove airborne particles, including particles that may contain viruses, from indoor air. However, performance varies by technology, room size, airflow, and operation. Air purifiers should be viewed as one part of a layered strategy rather than a guarantee against infection.
Should I use a portable air purifier or a whole-home system?
A portable unit is designed to clean air in a particular room or area. A whole-home system works with central HVAC equipment and can provide broader coverage. The right choice depends on your home and HVAC setup.
How often should I change my HVAC filter?
Follow the filter and HVAC manufacturer’s recommendations, and check the filter regularly. Homes with pets, higher dust levels, or other indoor air concerns may require more frequent attention.
