How Often Should You Clean Ducts in Your Building?

Building managers understand the importance of indoor air quality. It’s the air that workers in office buildings and students in classrooms breathe every day. It’s the air that patients at healthcare facilities and visitors to spas and restaurants take into their lungs. The transmission of airborne viruses is scary enough, but dust, mold, and allergens also pose threats to the health of building occupants. However, many business owners and managers wonder, how often should you clean ducts? Here is some guidance on when to clean ducts, but first, let’s look at the importance of maintaining clean ducts. Benefits of Maintaining Proper IAQ A link exists between poor indoor air quality and lower test scores in students as well as lower worker morale. When the air we breathe indoors contains allergens, mold, bacteria, and other pathogens this makes us sick. Poor IAQ leads to Sick Building Syndrome which causes headaches, and eye, nose, and throat irritation. It also triggers allergies and asthma and lowers cognitive performance. It causes employees to miss workdays and lowers productivity. A loss of ...

Indoor Air Quality Regulation Needs Public-Private Partnership

The ongoing pandemic puts indoor air quality issues in the spotlight, however, IAQ concerns predate COVID. For example, schools across the U.S. already faced an IAQ crisis in their buildings prior to the coronavirus. In fact, in early 2020, the U.S. General Accountability Office (GAO) published a report revealing that roughly half of U.S. schools need multiple system upgrades with one-third in need of HVAC updates. Failure to address these issues leads to health problems. Combine this with the dangers presented by the pandemic and IAQ regulation is sure to follow. Before that happens, however, the formation of a public-private partnership for indoor air quality regulation will benefit all parties. Dangers of Poor IAQ As we’ve discussed in this forum, the negative impact of IAQ on building occupants is well documented. Poor IAQ not only leads to health issues such as asthma and Sick Building Syndrome, but it also impairs cognitive functioning. The result is lower productivity for workers and lower test scores for students. To provide safe IAQ, keep schools open, and workers safe, a partnership ...

Workplace Air Quality Now A Top Priority for Employers

In recent years, employers have come up with an array of office perks and benefits to attract workers and keep them happy. While free snacks and beverages are a nice perk and unlimited vacation days sounds nice too, a healthy work environment is what workers need most. That includes the air we breathe. About three percent of the air an occupant in the average office building breathes in consists of air exhaled by other people. This is why workplace air quality is important, especially during the pandemic. Workplace Air Quality Virus transmission is a top concern for building managers as the spread of the Omicron variant reminds us. Pure Air Control believes taking on issues of workplace air quality requires more than a whack-a-mole strategy. In fact, getting more fresh outside air into the work environment is critical. This requires a prescriptive approach to IAQ that includes testing, cleaning, and restoration as well as monitoring to meet ASHRAE Standard 62.1 for ventilation rates. The combined approach offered by Pure Air Control is a way to get cleaner ...

How Often to Clean AC Coils?

With the Omnicron variant blazing its way through the US, issues of indoor air quality remain a top concern for building managers. Proper ventilation is critical to controlling its spread. Therefore, cleaning and maintaining HVAC systems is also important. One concern many business owners and managers have is, how often to clean AC coils. ASHRAE provides guidance on this topic and Pure Air Control Services provides the services and methods to make it happen. The Importance of Cleaning HVAC Coils Regular inspection and cleaning of HVAC coils result in optimal equipment performance. As little as 3/16 of built-up dirt and debris across the coil affects mechanical efficiency by as 20 percent. At a minimum, ASHRAE recommends inspecting coils at least once a year and cleaning as needed. For example, ASHRAE Standard 62.1 details the minimum ventilation rates as well as other measures to ensure IAQ is safe for occupants.  An HVAC assessment followed by a thorough steam cleaning of the coils is a way to comply with this standard. It also ensures the health and wellbeing of ...

Improving IAQ in Schools in 2021

As school started in the fall, we examined ways in which IAQ impacts schools and universities. We also looked at how school buildings benefit from improved indoor air quality. Next, we presented various methods and services for correcting school IAQ issues. We also noted that the pandemic offers a rare opportunity to administrators for improving IAQ in schools.  Mold Found in Student Housing As students returned to school in the fall, we took a look at some of the issues facing facilities managers at the college level. Improving IAQ in their schools is important to the safety of students and staff. For schools experiencing hot, humid conditions over the summer months, mold in dormitories is an issue. For example, we looked at a recent case at Villanova University in Pennsylvania. A period of high temperatures and heavy rainfall created an ideal environment for mold to flourish and complaints from students doubled in the first weeks after moving in.  Mold exposure triggers symptoms of congestion, runny nose, and sore throat. It can lead to more serious respiratory conditions ...
