A new steam humidification system and air exchangers improved IAQ and reduced skin problems for residents of the Middletown Home in Middletown, PA.


Humidification makes surprising difference for seniors and staff

When Diane Leonard learned that they were going to add humidifiers to the nursing home where she works, she never imagined the difference it could make.

“I knew humidity was important to the health of our residents,” says Leonard, assistant administrator at The Middletown Home in Pennsylvania. “But I remember thinking ‘how good can it be?’”

Within a few months of increasing the humidity levels in the home, Leonard says that she could feel the difference. “It was the first winter at the home where I didn’t have a constant dry, sore throat,” she says. The impact on residents has also been dramatic - with far fewer respiratory infections, as well as fewer skin tears due to dry skin. “There just seems to be less sickness overall, among residents and staff.”

CLEANING THE AIR

A skilled nursing facility that houses more than 100 residents, Middletown made the decision to add humidifiers as part of a project to update their 30-year-old heating and cooling system. They were looking to be more energy efficient, to have more control over the temperature in the building, and to create a more comfortable environment for their residents. The project included adding four new air exchangers, cleaning out the ducts, and adding a steam humidification system.

When Middletown decided to add humidification to their heating and cooling system, they turned to Nortec agent, Ron Zaritzky of Thermal Specialties Company, Nortec’s local agent in Lancaster, PA. “Ron really knows his stuff,” says Joel Frank, maintenance supervisor for the home. “And he worked right alongside our project team to make sure the humidification system was installed correctly and everything was running smoothly.”

Zaritzky, worked with the owner and staff at Middletown, and Herre Bros. Inc., a local contractor, to come up with the safest and most cost-effective solution for the building.

Middletown wanted to use the steam being generated by their boiler, but there were concerns about the potential for chemicals from the boiler to be released into the air. Together they decided on the Nortec SeTC Steam exchange humidifiers: a “steam-to-steam” solution that uses the steam from the boiler to feed the SE heat exchanger to boil clean water, creating atmospheric steam that is then discharged into the home.

ADDED HUMIDITY IMPROVES IAQ

Dry nose, cracked itchy skin, and sore throats are just some of the many side effects of living in an environment that is low in humidity. New research from the Oregon Department of Health Services has also demonstrated that the right levels of humidity can reduce and prevent against harmful bacteria and respiratory infections. The research puts the optimal humidity levels for good health are between 40% and 60%.

After adding the humidification system, Middletown’s humidity levels went from an average of 20% to between 40% and 45%, and the impact on residents was almost instantly noticeable. Skin tears went down an average of 50% in the first three months compared to the same period the year before, and respiratory conditions including colds and sinusitis were almost nonexistent.

“Keeping residents healthy and more comfortable improves their quality of life,” says Nicole Brandt, a registered nurse and infection preventionist at the home. “Healthy residents are more social and able to participate in more activities. it makes them physically and mentally healthier, and happier.”

BETTER AIR QUALITY MEANS BETTER BUSINESS

Making the investment in Nortec’s humidification system makes good business sense for The Middletown Home, who has been able to substantially reduce the amount of illness among residents. “The Health Department makes it mandatory for hospitals to maintain certain humidity levels, but there are no rules for nursing homes,” says Joel Frank.

“So we decided it was up to us to create a healthier environment for our residents. Seeing them up and around, and less bedridden, has made the investment well worth it.” ES
