Relative Humidity & Airborne Viruses

2 minute read

Winter is upon us and cold temperatures are forcing us to retreat inside for warmth. Unfortunately, as we increase the temperature on our thermostat, we also remove moisture from the indoor air, thus lowering our home’s relative humidity (RH). This lowered humidity does more than create comfort issues — it can also create health problems.

This dry indoor air can leave our skin and lips feeling chapped, cause bloody noses and sore throats, and result in an increase in static shocks. More importantly, dry indoor air increases the transmission rate of airborne viruses like the flu and COVID-19.

Keep Your Home’s Relative Humidity Between 30-60%

ASHRAE and the Centers for Disease Control and Prevention (CDC) recommend keeping your home’s relative humidity between 30-60%.

Whole-Home Products

A whole-home Aprilaire humidifier can help reduce the transmission rate of airborne viruses by adding moisture back into your home’s air. Keeping the humidity in your home between 30-60% will help reduce the negative effects of dry indoor air like dry skin, chapped lips, and sore throats. It will also help protect your home’s furnishings that can crack in dry air. We have a number of different humidifiers to keep your home properly moisturized depending on the need. Each humidifier is manufactured and designed in the United States and comes with a 5-year warranty. In addition, you do not have to empty water trays as you would with a portable unit.

For the ultimate effective virus protection, the Aprilaire Healthy Air SystemTM combines humidity control with fresh air ventilation and air filtration to keep your home protected from airborne viruses. The suite of award-winning products helps dilute and remove contaminants from the air to help you breathe easy in your home. Additionally, the system can be customized depending on your area’s specific climate needs.

Finishing Your Basement – Things to Consider

2 minute read

Click play to listen to the Finishing Your Basement – Things to Consider article. 

A finished basement can add value to your home, create extra living space for a growing family, and let you earn extra income by renting it out as an apartment.

When you’ve decided to take on the exciting renovation project of finishing your lower level, you’ll want to keep a few things in mind to guarantee a space that’s comfortable and healthy for years to come.

Air-Tight Seal

The basement is the lowest point in your home, meaning it’s the most at risk for pooling and settling moisture. If your basement and/or crawl space are underground, make sure you have proper encapsulation and waterproofing to keep additional moisture from seeping in.

Remove Mold

If it’s been a few years since you’ve maintained your basement space, there may be mold present that you’ll need to remove before starting renovations. You may need to hire a mold removal specialist, or you can tackle the task yourself if the mold isn’t overwhelming.

Identify Pests and Mites

Termites and mites can wreak havoc on your home and its foundation, but moisture control can make all the difference. Due to their relatively thin layer of skin, mites cannot survive in 50 percent humidity. They need hot and moist air, so proper humidity control with an Aprilaire dehumidifier makes it nearly impossible for pests to survive.

Plumbing and Wiring

If the basement space isn’t already wired for plumbing and electricity, you’ll need a trained professional to inspect the area and install the new hardware safely. It’s also likely that you’ll need a permit to complete this work, so check with local guidelines before starting the project.


The basement can be one of the largest sources of energy loss and increased utility bills in your home. It’s crucial that you insulate doors in those spaces, whether they enter directly into your home or connect to the outside. Any pipes and ducts should be insulated as well. This will help regulate the air temperature in the basement, which can help preserve a consistent environment throughout your home.


The air in your basement can circulate throughout the entire home. This becomes an issue when the basement air is excessively humid and potentially carrying mold and mildew. An Aprilaire dehumidifier can keep air in the optimal humidity range of 40-60% to prevent the spread of unhealthy air. Consistent humidity control can also save energy usage and prevent overtaxing of your heating and cooling systems.

Exterior Pressures

Underground basements feel pressure from the ground on all sides, which can lead to cracks and holes that let in moisture and pests. If excess moisture is a recurring problem, you may need to redirect downspouts or regrade the earth around your home to direct moisture away from the foundation.

Breathe the Fullness of Life: Tips from a Healthy Air Hero

4 minute read

You may know the air inside your home plays a key role in your overall wellness. But how much do you know about the impact of humidity and maintaining the right balance? Fortunately, Aprilaire Healthy Air Hero Scott Merritt of Fire & Ice Heating and Air Conditioning, Inc. is here to shed some light. From alleviating seasonal allergies to just breathing better, he discusses the unseen benefits of Healthy Humidity.

Interview with Healthy Air Hero Scott Merritt

Thank you for speaking with us, Scott. Can you start by telling us where in the U.S. Fire & Ice Heating and Air Conditioning, Inc. provides service? How long have you been in business, and how long have you been working with Aprilaire?

“Fire & Ice operates in Central Ohio, in the greater Columbus, OH area. We’ve been in business for 17 years and, in that time, we’ve grown to become one of the city’s largest HVAC contractors.

We partnered with Aprilaire a handful of years ago because we identified their products as top-notch. It’s been a beneficial partnership, and we truly believe we’re providing top-of-the-line Indoor Air Quality solutions to our customers.”

While most homeowners probably think about the temperature inside their homes, they may not be aware that humidity also plays a role in maintaining Healthy Air. How does Healthy Humidity impact a home?

“There are a number of homeowners who won’t even consider the humidity of the home when talking about heating and cooling. And it’s not their fault! There’s a lack of education in this area, and if you’re a new homeowner, you might be dealing with a system for the first time in your life. So a lot of what we do in our efforts is informational.
One of the primary functions of an air conditioner is to dehumidify the home, for example. But that’s not usually how it’s presented. So, the idea that a whole-home dehumidifier can aid your air conditioner isn’t obvious until that knowledge is there.”

Along with allergens, pollutants, and mold, humidity levels in the air you breathe can affect your overall wellness. Can you explain how Healthy Humidity impacts your health?

“The seasonal stuff is usually what we focus on, like allergies in the spring and summer and how proper humidity levels in the winter can reduce the risk of flu infections and other diseases (including coronavirus!). Almost everyone deals with those in some form. There really are a ton of unseen benefits.

I’ll give you a very personal example: my mother has trouble breathing, particularly in the summer. I purchased a whole-home dehumidifier for her, and it’s been the difference between her struggling to breathe at times and her home being the comfortable place for her. So it really can be life changing.”

At Aprilaire, we recommend that humidity in the home should be kept between 40-60%, which is optimal for human health and comfort. In your words, what is balanced humidity and why is it important?

“Most expert sources agree on that range, and our educational materials recommend at or near 50% as the optimal level. But to maintain that requires proactive management of your home’s humidity. It won’t simply hover there most of the time unless you’re using humidity-controlling products to their maximum benefit.”

It’s important to maintain a balance when it comes to humidity. What are the causes of high humidity in one’s home?

“There are probably too many to list, but homes with a basement will have higher humidity, and where you’re located in the country also matters. Few people in Arizona may truly need a whole-home dehumidifier, for example, but everyone in Florida would benefit from one. And vice-versa for whole-home humidifiers. Here in Ohio, we get both humid and dry weather, so we usually recommend both.

Windows and insulation matter as well, of course. As HVAC experts, that’s what we always try to look for, and a good HVAC system can usually make up for deficiencies in those other areas like old windows or a basement that’s prone to moisture.”

How do Aprilaire whole-home dehumidifiers work to effectively combat high humidity?

“Here’s an example: our General Manager here at Fire & Ice has a flooded basement, and we loaned her one of the Aprilaire units we had here in the office. Twenty-four hours and dozens of gallons of collected water later, and she had a relatively dry basement again.

One of our sales representatives also installed an Aprilaire whole-home dehumidifier to manage the heat on his second floor in the summer. His kids got used to sleeping downstairs during the hottest months, but now they can stay upstairs all year.

These stories are reflected in the feedback and testimonials of hundreds of our customers because these are common problems. Good humidity control is often the right answer.”

Lastly, a homeowner may not be sure if they are maintaining the right humidity. When is the best time to address humidity in your home?

“Any HVAC company worth its salt should be willing to have that conversation with you without any charge. A lot of people bring up these questions when one of our technicians is at their home for a tune-up or other maintenance, so that’s always a convenient time to inquire.

Even if you’re not considering a new furnace, AC, or heat pump any time soon, though, there’s no bad time to fix these issues in your home.”

2 minute read

Click the play button to listen to the post

We take the importance of caring for others to heart at Aprilaire. We believe we have a purpose beyond the individual work we do and that being a successful company also means “Being a Good Neighbor.” It’s one of our core values, and something we put into action each year.

We remain committed to helping our local communities in a number of ways, including financial contributions and volunteering. In the past, we’ve raised funds to provide pack-n-plays to mothers in need, volunteered at local blood drives, and held various donation drives throughout the year.

While our partnership opportunities may look different in the wake of the COVID-19 pandemic, we’re excited to continue our work with the Society of St. Vincent de Paul, whose mission statement reads:

“A membership organization, the Society began working in Madison in 1925 with two parish-based groups of members serving their neighbors in need. Today, programs the Society operates in Dane County include a large customer-choice food pantry, a charitable pharmacy, storage for the goods of persons who are homeless, seven thrift stores offering direct charity, housing at Port St. Vincent de Paul and St. Elizabeth Ann Seton House, and several other forms of assistance for people struggling with poverty.”

We’ve been working with St. Vincent de Paul – Madison since 2014, giving us a number of incredible opportunities to give back and live out our mission of being Good Neighbors.

We believe the work they’re doing to provide assistance for our community is more important than ever right now, which is why it’s our honor to be a 2021 Platinum Sponsor for St. Vincent de Paul’s 6th Annual Care Café fundraising breakfast on May, 5th 2021. The theme is “Love Made Visible.”

They’re going virtual this year, which means they have unlimited capacity to reach their goal of $140,000. If you live in Dane County, we encourage you to attend the virtual event and support our neighbors in need through your contributions to the food pantry, free pharmacy, and housing programs.

Experiencing the Fight For Air Climb

2 minute read

Before the Fight For Air Climb

Entering the US Bank Center for the American Lung Association’s Fight For Air Climb was a rush of energy.

This seemed less like an arduous trek up 1,000 stairs and more of an indoor festival. There were volunteers ready to greet you and pump you up for the ensuing climb and people from different companies sitting at tables ready to hand out souvenirs.

They were probably also there to distract you after you just got done instinctively looking up toward the top of the 47-story US Bank Center in downtown Milwaukee becoming a little uneasy at the prospect of your journey upward.

Before you made your climb, you gathered as a team and took several escalators down to the basement level before getting warmed up with a quick aerobic routine. Then you took a long and winding tunnel where you greeted by more volunteers who were cheering you on. It was hard not to feel inspired and excited.

During the Fight For Air Climb

One-by-one people took off up toward the top of the US Bank Center to begin their Fight For Air Climb. I, like most, started off confidently and quickly. I took the first six flights easily, but then by flight eight, I began to fight for air. I now understand why they title this climb just that. My mind and my body were at odds. I couldn’t decide whether I wanted to continue at the same pace to get it over with as quickly as possible or to slow down and feel better. I went with the former.

Everyone in the stairwell was trudging onward with the same dilemma. We all were gasping for air as we kept pushing up each step and each flight toward the top of the Fight For Air Climb. At several points, I wondered if I was actually making any progress.

Every 10 flights there was a group of volunteers handing out cups of water and words of encouragement. Both were sorely needed to help push me along.

With each passing flight, I kept a tally of how many flights I had left. Twenty flights down, 27 more flights to go; 30 flights down, 17 flights to go; Ok, 40 flights down, 7 to go. By the time I got to the 40th floor, I knew I could make the last push to make it to the top of my Fight For Air Climb journey.

After the Fight For Air Climb

Eventually, I reached the top after 9 minutes and 31 seconds. At the top of the stairwell, I was met by volunteers who were cheering me on and by other climbers who were also catching their breath and taking in the picturesque views of Milwaukee and Lake Michigan afforded to us by the tallest building in Wisconsin.

As I grabbed a water and walked around soaking in both the views of the city and my accomplishment, it was really cool to watch teams taking pictures together or greeting other climbers with high-fives and smiles. There was a certain camaraderie found in a common struggle.

Despite the lingering soreness, I cannot wait for next year’s climb. No matter if I beat my time from this year or not, it’s about fighting for air together and helping those impacted with lung disease.

Breathing Healthy Air: Interview with the American Lung Association

4 minute read

At Aprilaire, we encourage breathing Healthy Air because we know it benefits your overall health. The American Lung Association knows it too. That’s why Aprilaire air filters are the National Proud Partner of the American Lung Association*, playing a key role in the fight to improve lung health and prevent lung disease.

We got to interview National Senior Vice President of Development Sally Draper about the importance of Healthy Air and how both Aprilaire and the American Lung Association are working together to help you Breathe the Fullness of Life.

Could you introduce yourself for the readers and tell us about why you chose a career with the American Lung Association?

“I joined the Lung Association in 2014 because I was attracted to its comprehensive mission—to save lives by improving lung health and preventing lung disease. Every day we help Americans breathe easier through our efforts to fund innovative research, advocate for policies that protect our lungs, and educate patients, caregivers, providers, and the public with science-backed information. We were founded more than 115 years ago, and the needs are greater today than ever before, including the youth vaping epidemic, climate change, and COVID-19!”

Can you tell us about the American Lung Association’s mission?

“The American Lung Association is the leading organization working to save lives by improving lung health and preventing lung disease. Our work is focused on four strategic imperatives: to defeat lung cancer; champion clean air for all; improve the quality of life for those with lung disease and their families; and create a tobacco-free future. Whether it’s searching for cures to lung diseases, keeping kids off tobacco, or advocating for laws that protect the air we breathe, the work of the American Lung Association helps to save lives every day.”

How did Aprilaire and the American Lung Association come to work together in the first place? What does that relationship look like presently?

“Aprilaire and the American Lung Association forged a new relationship in 2018. We quickly realized how much we had in common. Our partnership was developed as we saw an opportunity to educate and help more consumers improve the air in their homes to create a healthier environment.

Since 2020, Aprilaire has been a Proud Partner of the Lung Association with its 4” residential air filters. Additionally, Aprilaire joined the Lung Association as our FY20 National Fight For Air Climb Partner For Healthy Air. The company has also supported the Lung Association’s “Stand Up For Clean Air” campaign. As part of this initiative, we are driving conversations around air quality, climate, and health. The Lung Association invited people to share their #MyCleanAirStory—knowing that when people realize climate and air quality are impacting the health of their neighbors, friends, and loved ones—they are more willing to act. Aprilaire provided prizes for the #MyCleanAirStory contest, including one grand prize of a whole-home Indoor Air Quality upgrade (the Aprilaire Healthy Air System™) and nine Aprilaire Room Air Purifiers. This year, the company stepped up once again to sponsor the Wisconsin Fight For Air Climb in Milwaukee. Also in 2021, the Lung Association welcomed Dale Philippi, President and CEO of Research Products Corporation, Aprilaire’s parent company, to the Lung Association’s Wisconsin Leadership Board of Directors.”

Tell us about the Fight For Air Climb.

“The American Lung Association’s Fight For Air Climb is the nation’s premier stair climbing challenge. At 38 events nationwide, children and adults of all ages participate in this celebratory stair-climbing adventure. Pre-pandemic, the Fight For Air Climb was held in several of our country’s most iconic skyscrapers. This year, the Lung Association invited participants outdoors for a one-of-a-kind adventure to support healthy lungs and clean air. In fact, Dale was among the company’s team of more than 50 employees that climbed the stairs at Milwaukee’s American Family Field on May 22nd, proving he puts his feet, time, and talent behind causes he supports.

Aprilaire has been a stalwart partner in the Fight For Air Climb, promoting the event to employees, customers, trade partners, family, and friends. Through this unique vehicle, the company is engaging individuals of all ages to understand and celebrate the importance of Healthy Air.”

Aprilaire’s air filters are a National Proud Partner of the American Lung Association. How do you feel our mission aligns with yours?

“Our CEO, Harold Wimmer, has said, ‘Breathing should not be an uphill battle, but for many it is… no one should have to fight for air on a daily basis.’ Similarly, Dale has declared, ‘We believe everyone deserves to breathe Healthy Air.’ As a National Proud Partner, Aprilaire’s mission to enhance everyone’s health by improving the air in their homes aligns very closely with that of the American Lung Association, champion of clean air for all.”

What are the benefits of breathing Healthy Air and what are everyday things that people can do to Breathe the Fullness of Life?

“Clean air is essential for healthy lungs. The American Lung Association works to ensure that the air we breathe is clean and safe from harmful pollution. In fact, every year we publish our State of the Air Report, which looks at two of the most widespread and dangerous air pollutants, ozone and fine particulate matter. Our 2021 State of the Air Report found that more than 4 in 10 Americans—over 135 million people—are living in places with unhealthy levels of ozone or particle pollution.

One of the most important things you can do to Breathe the Fullness of Life is to keep sources of pollution out of your home. Check out these commonsense tips on Additionally, ventilation helps reduce indoor air pollution, but it works best if paired with keeping known sources of air pollution out of the building. For tips on how to use ventilation to protect your lung health, check out our section on Ventilation: How Buildings Breathe.”

Fight for Healthy Air

At Aprilaire, we believe everyone deserves to Breathe the Fullness of Life, and we’re not the only ones that feel this way. Through our Proud Partnership with the American Lung Association, we aim to fill every home with Healthy Air. Both Aprilaire and the Lung Association believe that breathing Healthy Air should be available to everyone, and maintaining healthy Indoor Air Quality is an important step for your lung health.
