Understanding Bioaerosols
According to ScienceDirect, bioaerosols are suspensions of airborne particulate matter of biological origin (BioPM) which includes microorganisms and the products of these organisms.
They include bacteria, viruses, fungal spores, and pollen. Exposure to bioaerosols can lead to a range of health issues, from allergic reactions and asthma to serious respiratory infections. Ensuring these particles are efficiently removed from indoor air is essential for public health.
How Fiberglass Filters Work
Fiberglass filters are composed of fine fibers made from glass, arranged randomly to create a dense, porous mat. These filters capture particles through several mechanisms:
1. Impaction: Larger particles collide with the fibers and are trapped.
2. Interception: Particles following the air stream come into contact with the fibers and adhere to them.
3. Diffusion: Smaller particles move randomly (Brownian motion) and are captured by the fibers.
Effectiveness of Fiberglass Filters Against Bioaerosols
Fiberglass filters are widely recognized for their efficiency in capturing bioaerosols. According to the guidance document by the National Institute for Occupational Safety and Health (NIOSH), fiberglass filters, particularly those classified as F7 according to the EN 779 standard, are highly effective in filtering out biological particles from the air.
Research cited in the document shows that HVAC systems equipped with high-efficiency filters can significantly reduce the concentration of airborne viruses and bacteria in indoor environments.
This reduction is crucial in preventing the spread of infectious diseases, especially in settings where people spend a considerable amount of time indoors, such as offices, schools, and healthcare facilities
Applications of Fiberglass Filters
According to the guidance, several case studies highlight the successful application of fiberglass filters in improving indoor air quality:
1. Office Buildings: Implementing high-efficiency fiberglass filters in office HVAC systems has led to a noticeable decrease in employee sick days and increased productivity.
2. Healthcare Settings: Hospitals and clinics have reported reduced incidences of hospital-acquired infections after upgrading their air filtration systems to include fiberglass filters
3. Public Buildings: During outbreaks of airborne diseases, public buildings such as libraries and transportation hubs have utilized fiberglass filters to help control the spread of pathogens
