It makes perfect sense: healthier employees are happier employees. However, many business owners believe developing a wellness program or a smoking cessation class is the path to employee happiness. Not so fast.

Indoor Air Quality (IAQ) affects Productivity

According to a recent study commissioned by the Building Engineering Services Association in the United Kingdom, almost 70 percent of office workers polled said poor indoor air quality in the workplace made for negative feelings, and worse, lowered productivity.

“The health impacts of poor outdoor air quality are well-documented and have been linked to respiratory tract infections, lung cancer and chronic obstructive pulmonary disease,” said Steven Loughney of Siemens Building Technologies in a report. “Indoors you’ll find these same pollutants intermingled with dust, carpet fibers, fungal spores, cleaning products, photocopy residues or building materials, which create quite an unhealthy cocktail of contaminants that eventually permeate across the workplace.”

Is it Sick Building Syndrome?

Indoor spaces where poor air is circulated ad nauseum often create symptoms of Sick Building Syndrome—sluggish behavior, frequent headaches, lowered resistance to viruses and colds, difficulty concentrating and increased absenteeism—among occupants.


The EPA estimates that Sick Building Syndrome accounts for $60 billion in lost revenue per year. What’s more, it’s estimated that $220 billion is lost in worker productivity due to absenteeism and employee sickness. In fact, the average cost of one employee sick day is $2,650.

How can you address this?

In many cases, poor building design and inadequate ventilation systems are to blame. There is a way to quickly boost IAQ, making employees both happier and healthier: installing AeraMax Professional air purifiers.

These commercial-grade air purification systems effectively and efficiently remove up to 99.97 percent of airborne contaminants, like viruses, odors, volatile organic compounds and bacteria from enclosed spaces using hospital-like True HEPA filtration.

The four-stage filtration system of AeraMax Professional systems automatically senses when air needs to be cleaned, working behind the scenes to refresh air and improve the overall health of occupants. That, in turn, can overcome the effects of sick building syndrome and reverse the negativity experienced by employees. So, in this case, healthier means happier.

When business owners hear that indoor air is two to five times more polluted than outdoor air—which is already heavily polluted—they think the solution lies in focusing on the building’s HVAC system. But that may not solve the problem of poor air quality.
Here’s why:

 

HVAC systems recirculate

HVAC systems work because they recirculate air. But they don’t do a thing about cleaning the air. Filters can trap very large particles, but things like volatile organic compounds (VOCs), germs, bacteria and allergens pass right through typical HVAC filters. That doesn’t alleviate the problem of poor air quality inside buildings.

Business owners and facility managers may think installing HEPA filters in existing HVAC systems will do the trick. It won’t. That’s because HEPA filters designed specifically for HVAC systems are bulky, and while they do a better job of trapping germs in the direct area near the intake, these thick filters drag down HVAC efficiency, significantly reducing airflow. So, HVAC will work harder, break down more often and still not solve the poor air quality problem. Additionally, these modifications to existing HVAC systems do nothing for areas that aren’t near the intakes.

HVAC systems spread germs farther and faster through recirculation.

Perhaps most importantly, HVAC systems spread germs farther and faster through recirculation. In essence, HVAC systems are air movers, not air improvers. There just isn’t enough efficiency in HVAC systems, because they are designed first and foremost to push air throughout buildings. Also, HVAC systems focus on the entirety of buildings, pushing air at the same rate throughout. That means indoor air quality problem areas will be ignored.

 

For improvement in IAQ, focus on cleaning instead of moving the air

Instead of recirculating poor air, building managers and business owners need to focus on removing it. In our opinion, the best way to do that is by installing AeraMax Professional air purifiers. These commercial-grade systems use hospital-type True HEPA filtration to effectively, quickly and efficiently remove 99.97 percent of airborne contaminants, like germs, bacteria, smoke, odors, allergens and VOCs, from indoor air. The four-stage filtration systems work automatically, because the units sense when poor air is present, adjusting to remove the bad air.

And, AeraMax Professional offers an array of different units to accommodate a variety of room sizes—and even have portable units so specific areas can be targeted on the fly, by moving the purifier into offending areas.

In recent years, researchers have charted a medical phenomenon that affects a wide swath of people with no discernable connection—save one. All the people who experience symptoms of headaches, tiredness, ear, nose and throat irritation, dizziness and nausea have one thing in common: They spend a large amount of time in buildings. And the buildings are making them sick.

Sick Building Syndrome is a malady related to poor air quality in a building—air with germs, volatile organic compounds (VOCs), allergens and pathogens that is recirculated and “trapped” through inadequate ventilation. Compounding the problem is the fact that many buildings are constructed specifically to trap this air, with no way of opening windows. Likewise, older buildings have HVAC systems that cannot handle increased airflow—or worse yet, are “dialed down” to save on energy costs.

Newer, more energy-efficient buildings aren’t immune to the problem of Sick Building Syndrome either. According to the World Health Organization, up to 30 percent of new or remodeled buildings also cause Sick Building Syndrome. That’s because paint, solvents and adhesives used in new construction produce VOCs, as do new furniture and newly installed carpeting.

One way to potentially ease the threat of Sick Building Syndrome is to thoroughly scrub inside air. But given that indoor air is constantly being infiltrated with outdoor air—though open doorways and outside access—it’s important to continually monitor and clean it. And that’s exactly what the complete line of AeraMax Professional air purifiers were designed to do.

These commercial-grade air purifiers use a four-stage filtration system employing hospital-like True HEPA filtration to eliminate 99.97 percent of airborne contaminants from enclosed spaces. So, while conventional HVAC systems exacerbate the problem of sick air, AeraMax Professional actually removes it, cycling cleaned air into the enclosed space.

The units have a unique sensing system, which continually monitors the air, adjusting to clean air when necessary. Since they are effective in removing VOCs from the air, they are also ideal in new construction, or buildings that have been recently remodeled.

It makes perfect sense: healthier employees are happier employees. However, many dental lab owners may believe developing a wellness program or a smoking cessation class is the path to employee happiness. Not so fast.

According to a recent study commissioned by the Building Engineering Services Association in the United Kingdom, almost 70 percent of office workers polled said poor indoor air quality in the workplace made for negative feelings, and worse, lowered productivity. The same could be true of dental lab workers, who work in dusty, close quarters amongst grinding machinery kicking up particulate into the air.

Two studies have shown that sick building syndrome and hanging around indoors can actually make you sick. Scientists have long known that increased levels of carbon dioxide (CO2) contribute to global warming and, in turn, harm the environment, but thought that indoor levels of CO2 weren’t particularly harmful to occupants. They were wrong.

A study conducted in 2012 by the Department of Energy’s Lawrence Berkeley National Laboratory assessed the effects of CO2 in enclosed spaces, where concentrations of the gas may be higher because of recirculated air. In a controlled setting meant to mimic an office environment, participants were subjected to increasing levels of CO2, ultimately reaching amounts people would experience during a typical working day.

As a benchmark, typical CO2 levels in outdoor air are 400 parts per million (ppm), where facility managers try to keep CO2 levels indoors below 1,000 ppm, through ventilation and air circulation. However, researchers found that crowding in office spaces of conference rooms could bring CO2 levels up to 2,500 ppm; according to Berkley scientists, classroom levels in schools can reach 3,000 ppm.

 

CO2 Impairs Concentration

In the study, participants were given computer-based decision assessment tests once they had acclimated to increased CO2 levels. The result: the participants had impaired thinking processes, couldn’t concentrate and reached “dysfunctional” levels of performance.

The most recent study, conducted by Harvard University, SUNY Upstate Medical Center and Syracuse University used a similar approach and confirmed the earlier test’s results. Researchers were shocked that insignificant increased in CO2 levels could impair function that quickly.

 

Increase Ventilation & Minimize Overcrowding

According to a recent paper published by Joseph Allen, an assistant professor of exposure assessment science at Harvard, increasing ventilation is one way to combat the CO2 problem and Sick Building Syndrome—the conditions, like headaches, respiratory problems and cognitive impairment, brought on by indoor air pollutants.

He estimates doubling current ventilation rates in buildings would amount to a cost of $40 per occupant per year, but would provide a productivity gain of $6,500 per person per year, offsetting any costs and providing companies more revenue via productivity.

Another way to combat Sick Building Syndrome is by reducing overcrowding in conference rooms, offices, building and classrooms; given that people exhale CO2, close quarters can contribute to the problem.

 

Clean The Air

A third way is addressing the air quality itself. While AeraMax Professional air purifier doesn’t remove CO2, it is extremely effective at removing debilitating viruses, allergens, and VOCs and purifying indoor air through a four-stage filtration system.
