How to Improve Your Indoor Air Quality During Cold & Flu Season

Winter is upon Greater Cincinnati, which means families need to watch out for coughing and sneezing due to colds. Cold and flu season is exacerbated even more in 2020-2021 due to the COVID-19 pandemic. In today’s blog from Air Authority, we talk about how to improve your indoor air quality during cold and flu season.

Open Windows

On mild days, open windows to let some fresh air into your home. Americans spend up to 90 percent of their time indoors, so open a window to refresh the air inside.

Let Sunlight In

Let plenty of sunlight into your home by opening the drapes and blinds. Indoor air quality is more than just dust and particulates in the air. Dust mites, or very tiny insects, can inhabit your carpets, drapes, bedding, and linens. Sunlight kills dust mites instantly, so it’s important to let sunlight into your home regularly.

Vacuum and Dust Frequently

Because you keep your home closed up for most of the winter, dust tends to settle on surfaces more frequently than during warm months. Vacuum and dust your home often, at least once a week, to keep particulates out of your HVAC system and out of your lungs.

HEPA Filters

HEPA filters remove more particles out of the air compared to ordinary filters. They also last up to three months (versus one month for regular filters). HEPA filters keep dust, allergens, pet dander, and even micro-organisms from getting into your home’s ductwork, thereby recirculating in your home and building up over time. Consider replacing your normal filter with a HEPA air filter for better indoor air quality this winter.


A whole-home humidifier needs very little maintenance. The device maintains humidity levels between 40 and 50 percent through your entire home so you can breathe easier, keep your nasal passages moist, and fight off colds and the flu. Indoor air quality is more than just removing particles from the ductwork. It’s also about adding the right amount of moisture during dry winter months.

Electronic Air Cleaner

An electronic air cleaner draws particles to it and traps them. Unlike HEPA filters, electronic air cleaners only need maintenance once per year. They also remove many more particles in your ductwork versus filters alone because they have larger surface areas with which to operate in your home’s HVAC system.

Nothing compares to a REME HALO whole-home air purifier. This award-winning product works fantastically for cold and flu season because of the cold temperatures outside. Our technician can install this device in less than a day. REME HALO products work by killing, not just removing, bacteria and viruses from the air.
