February is the peak of cold and flu season. If your office is anything like ours, everyone has gotten a bug at some point this season. In fact, it is the worst cold and flu season in almost a decade. It is on pace to reach the death toll of 2014-2015's cold and flu season. During that period, 56,000 Americans died of the flu.

1. Change your air filter
HVAC filters should be changed monthly with high-efficiency particulate arresting (HEPA) filters. These filters can reduce tiny particles in the air that can spread colds and flu.
2. Moisture in the air
Studies have found that the reason that flu season is in the winter is because of the lack of humidity. Humidity affects how long the flu virus is stable. It is believed that the water vapor deforms the virus.
Add a whole house humidifier to your property, if you don't already have one. In addition to deforming the flu virus, humidifiers reduce the symptoms of colds like sore throats, post nasal drip, congestion, and scratchy throat.
3. Keep temperatures warm
Button you coat; you'll catch a cold! While that is not true, what is true is that warm air holds more moisture than cold air. As you saw in the previous section, moisture help prevent the flu and reduce symptoms of a cold. Additionally, bodily natural defenses are less active in the cold. The silica hairs in your nose, which trap germs, become less effective in cold temperatures.
4. UV Lights
Did you know that UV lights used in HVAC systems have proven to reduce fungal growth? It's true. An NCBI study installed UV lights on certain floors of an office building and, as a control group, not on others. The UV light floors had reduced fungal contamination in the air-handling units, in the fiberglass insulation, and reduced airborne fungi in the floor space.
This year, Americans have already lost their lives to the flu. To keep your home, apartment building, or office healthy - try these four tips for reducing flu and cold viruses with smart HVAC decisions.
