Corona Virus — What you need to know

In a recent study by the CDC1, an air conditioning system has been connected to Covid-19. But what are the facts? Can an air conditioning help or hurt if we’re dealing with a pandemic? What does this mean for those of us at home?

How your HVAC system helps you stay healthy

Running your air conditioner or furnace filters your air from allergens, dust, and other particulates. This helps to keep everyone in the home feeling great. Normally, this might be all we need to know.

Fresh air is good for you, too!

Does the typical central air system bring in fresh air from outside? No. Your central air system is a closed system. To get fresh air into your home, you would need to either open windows or install a fresh air intake system like the one we use from Aprilaire or our one from Trane. This is a system that brings in fresh air while minimizing energy loss.

Our Aprilaire Fresh Air Intake System gives you all the advantages of your central air filtration (removing dust and pollen) and adds to it the great benefits of fresh air circulation from outside.

Can better filters help?

HEPA filters and our Trane filter can help keep your home healthier.

Filters can help people at home stay healthy according to a study by the American Society for MicroBiology2.

Most filtration systems for home HVAC systems are not able to filter out viruses. “However, viruses are rarely observed as individual particles, but instead are expelled from the body already combined with … other components as large droplets and aerosols,” reported the study (Pg 5, para. 1). When those larger particles are filtered out, any virus particles would be filtered out with it.

We’re fortunate to be in an area with beautiful outdoors and only a few Corona virus cases as of yet. That said, you may decide that a HEPA filter would be a great addition to your home and a way to add to the protective measures that you take for your family.

HEPA filters are used in hospitals and are very effective in filtering out smaller particles. They can also be installed in homes as an added safety measure.

We also offer a Trane CleanEffects filter which, after testing, has proven to be even more effective than a HEPA filter at filtering out particles.

Can a UV light filter help with Corona virus?

The quick answer – yes, UV light can help. The slightly longer answer is that the type of UV light that severely damages bacteria and viruses is UVC. The effect it has on viruses is it damages them so badly that they cannot reproduce. This type of UV light can’t be found at the beach, but it can be installed in your HVAC system at home.

UV filtration systems can help with Corona virus according to a BBC article.

UVC has become a staple method of sterilization – one used in hospitals, airplanes, offices, and factories every day,” reported a BBC article3. That said, we can’t say that UV light kills the Corona virus. There’s just not enough data yet.

This UVC light is only for trained professionals to install within your HVAC system. If you decide that you’d like this system installed in your home, ask for the UV filtration system. We’ll know just what you mean.

While social distancing and hand washing are helping control the spread of the Corona virus, good ventilation and HVAC systems can boost your home’s health factor. If you want to take extra measures, you might invest in an Aprilaire Fresh Air System, HEPA filter, Trane CleanEffects filter, or a UV filtration system (or a combination of these systems) for your home.
