Environmental Test Chamber Studies Ensure Product Efficacy

The COVID-19 pandemic has heightened the indoor air quality worries of businesses around the country. This is a well-founded concern. However, in the rush to increase ventilation and purify indoor air, many companies purchase subpar products that have undergone limited studies in labs that do not accurately create the real-world situations in which they will be used. By contrast, Pure Air Control Service’s EDLab tests products in an environmental test chamber (ETC) that simulates real-world scenarios.  This includes testing on technologies such as UVC/UVGI, needlepoint bipolar ionization, filtration, and a combination of air purification technologies that deal with SARS-CoV-2. Using an inadequate environmental lab chamber to test products leads to inaccurate results. This, of course, puts building occupants at risk. The Environmental Test Chamber The Pure Air Control Service’s EDLab is accredited by the American Association of Laboratory Accreditation (A2LA) and is a certified member of the CDC Elite program. As well, it is one of only a few environmental test chambers in North America. This state-of-the-art facility tests the effectiveness of air-cleaning and air filtration devices ...

IAQ Planning for Your Buildings in 4 Steps

When we’re indoors many of us assume we are safe from polluted air. This isn’t the case. Indoor air pollution threatens our health as much as outdoor air pollution. Maybe even more in some cases. If you run a business or own a building, you need to understand the importance of both indoor air quality (IAQ) and indoor environmental quality (IEQ), and you need to get onboard with IAQ business planning today. The Difference Between IEQ and IAQ According to The National Institute for Occupational Safety and Health (NIOSH) IEQ “refers to the quality of a building’s environment in relation to the health and wellbeing of those who occupy space within it.” This includes conditions of lighting, ergonomics, acoustics, thermal conditions, and air quality. That means IAQ is also a part of IEQ. Therefore, improved indoor environmental conditions lead to healthier building occupants.  A failure to address issues with IAQ planning many times leads to a condition known as Sick Building Syndrome. Symptoms of SBS include coughing, tightness in the chest, chills, fever, and muscle aches. These ...

Air Purification Restores Confidence in Workers

Does your staff feel safe while working in your building? You may think so, but don’t be surprised if they don’t. That’s what Honeywell Corp discovered in their commissioned study on the perceptions workers have when it comes to health and safety in the workplace. If that’s surprising you should know that air purification restores worker confidence. Two thousand workers took Honeywell’s comprehensive workplace survey conducted by Wakefield Research. The participants mostly worked in buildings with 500 or more employees. The study was done in the US, UK, Germany, and the Middle East. The majority—nearly 70 percent—reported that they did not feel completely safe in the buildings where they worked. The number was even higher for remote workers responding to the safety of their employer’s building. In fact, almost a quarter of the remote workers said they would rather quit than return to these buildings after the pandemic.  It’s no surprise that over half of the study participants voiced concerns about the transmission of the coronavirus in the workplace. Over half also don’t believe that building managers ...

HVAC Energy Efficiency Improves with Clean Systems

Great emphasis has been placed on indoor air quality during the pandemic and for good reason. The virus that causes COVID-19 spreads, at least in part, through aerosol transmission. Therefore, it makes sense that facilities managers would focus on the efficiency of heating, ventilation, and cooling systems. However, maintaining these systems is important for other reasons as well. Deep cleaning provides HVAC energy efficiency that prolongs the life of equipment and also removes contaminants from the air. It improves worker health, morale, and productivity. It also helps buildings meet ASHRAE standards and guidelines. Clean systems help in hitting temperature set points too. That reduces energy costs, which is never far from the minds of building managers. Improving HVAC Energy Efficiency Things that affect HVAC energy efficiency include built-up dust and debris in mechanical systems. This makes systems work longer to achieve the desired results. When systems fail to meet and maintain temperature set points, the air feels stale and conditions become uncomfortable. Odors develop and the risk of mold increases as well. HVAC Hygiene Assessment The first ...

IAQ Surveys Create Healthy Buildings

As a country, we have made tremendous progress in the battle against SARS-CoV-2, but even as vaccines go into the arms of millions of Americans and buildings reopen nationwide, the threat of COVID-19 variants is real. Therefore, this is not the time to relax social distancing guidelines or stop screening building visitors upon entry. It is certainly not the time to take our eyes off building HVAC systems or IAQ in general. In fact, indoor air quality surveys help building managers identify IAQ issues, minimize risk, and keep ahead of future government regulations. Most importantly, they keep building occupants safe. IAQ Surveys We know that the coronavirus spreads through aerosol transmission. Infected people expel tiny droplets when they cough or sneeze after which other building occupants breathe them in. They also land on hard surfaces and transfer through touch. While the risk of spread through ventilation systems is lower it still poses a threat. The bottom line is, improving HVAC systems reduces the risk of COVID-19 exposure and that requires completion of IAQ surveys. This includes assessments ...
