Building managers put much time and money into improving indoor air quality. These efforts doubled during the COVID-19 pandemic when disinfecting efforts increased. Managers also pay more attention to how HVAC concerns impact IAQ. Air purifier performance is another important tool in the fight against viruses and other pathogens, but not all commercial air purifiers are the same.
So what does a leading environmental microbiologist from a testing laboratory think about how to choose the right air cleaning device? What are the top must-haves for optimal air purification performance? To find out, we asked the director of the Environmental Diagnostics Laboratory at Pure Air Control Services, Dr. Rajiv Sahay, Ph.D.
5 Must-Haves for Optimal Air Purifier Performance
Pure Air Control’s EDLab is one of the only commercial environmental test chambers for product evaluations. The Environmental Testing Chamber (ETC) at EDLab evaluates air-cleaning devices. In addition, the lab tests air conditioning equipment, filtration, and asthma and allergy products. The lab has assessed air purification devices throughout the pandemic. Here’s what Dr. Sahay says are must-have features for best air purifier performance:
1. Multi-stage Filtration
Multi-stage filtration with both a HEPA and carbon filter is a must. It increases the performance of the air purifier and delivers air free of contaminants and odors. Of course, a HEPA filter with an anti-microbial coating returns even better results.
2. A Combined Approach to Assist Filtration
For best air purifier performance, devices should use needlepoint bipolar ionization technology to neutralize pathogens. Needlepoint bipolar ionization is a safe, effective way to clean the air. It generates millions of ions break apart organisms like bacteria, fungi and viruses. Best of all, unlike UV-C light, there is no maintenance or replacement parts for bipolar ionization technology.
3. Multiple Fan Speeds
Multiple fan speeds lets building engineers increase airflow as needed. Some purification devices use sensors to adjust to changes in the room. For example, when more people enter the space, the device increases airflow.
4. Quiet Operation
Loud fans distract staff and visitors in commercial business and are also a distraction with devices used in the home. Therefore, it’s helpful to choose an air purifier with quiet operation.
5. Smart Operation
The best air purifier performance comes through smart technology. This technology can detect motion and sound to control operations for better energy efficiency. These smart devices also use sensors to monitor particles, odors, and to alert you when filters need changing.
The Best Air Purifier Choice
True HEPA Air Purifiers devices check all the above boxes. These devices use a carbon filtration system to catch pathogens and particles. There’s also an antimicrobial-treated HEPA filter that traps 99.97% of any remaining particles. They also use bipolar ionization technology to destroy bacteria, fungi, VOCs, and odors and use smart technology to detect motion in the room and adjust air purification performance in response.
For best air purifier performance results, however, building engineers must keep up with filter changes. It’s easy to stay on top of this process with the True HEPA Air Purifiers commercial filter change program. Our technicians monitor equipment and keep a filter inventory. This allows them to schedule the appropriate time for servicing. Ask about the filter replacement program when you order your True HEPA air purifier.
