HALO Air Filtration Preventative Response of Aerosolized Transmission
Executive Summary
Erlab, Inc is the manufacturer of the HALO HEPA air purifier. We can assist facilities in protecting their customers, employees, and visitors. We offer you a long-term solution by providing a complete air treatment system with proven effectiveness at mitigating the risk of viral transmission and reducing viral load concentrations and other harmful pollutants. With 90% of our time spent indoors, addressing Indoor Air Quality (IAQ) is crucial to our overall health and well-being. At Erlab, Inc., we develop plans that address your challenges with solutions to achieve results.
Safe, Breathable Air
Aerosolized Virus Transmission
There are many ways a virus is transmitted, but airborne aerosolized droplets are the primary form of spread. When these micro-sized droplets are released, they remain suspended in the air for several hours (or longer). Even worse, they are recirculated through a building’s ventilation via the return and supply vents.
Unfortunately, these tiny droplets wreak havoc on our bodies—particularly our respiratory systems—as they are inhaled deep into our lungs. Our bodies cannot filter these tiny particles out, leading to lower respiratory tract infections and increasing the severity of the disease. However, because these droplets are so small, there must be a high “viral load,” or concentration, of droplets for transmission to occur. This will affect every individual differently, meaning we can never truly know what a safe environment is. Therefore, the best course of action is to put proper air treatment solutions in place to ensure cleaner, safer air for everyone.
Mitigating Risk – Improving the Indoor Air Quality (IAQ) in Your Commercial Space
The American Society of Refrigeration and Air-Conditioning’s (ASHRAE) positioning document on infectious aerosols states that the design and operation of HVAC systems can influence infectious aerosol transport. Still, they are only one part of infection control. Their positioning document on Indoor Air Quality (IAQ) and the CDC’s recommendation for ventilation in buildings outline the criteria facilities should follow to improve IAQ and decrease the risk of viral transmission.
- Increase air change rates (ACH) and minimum outdoor airflow rates.
- Ensure proper air distribution or dirty-to-clean directional airflow patterns.
- Increase air filtration within the ventilation without reducing design airflow or decreasing the air change rates.
- Add HEPA-filtered systems to enhance air cleaning.
Independent HEPA Filtration System: HALO HEPA
The ceiling-mounted HALO filtration system was originally designed to protect laboratory personnel from laboratory pollution exposure. The design was based on a delicate equation of the right airflow, carbon bed depth, and air distribution.
HALO is a long-term solution; HALO is a permanent infrastructure improvement without the infrastructure development costs or complexities. A solution for today’s challenges and tomorrow’s well-being.
