How Humidifiers Improve Airborne Infection Control in Schools

The kids may be back to school, but the minds of most are focused on reducing the spread of infectious viruses such as COVID-19. While we still seem to be facing an uphill battle in the fight, we cannot let our standards slip. Therefore, it’s important to consider how humidifiers improve airborne infection control in schools and similar environments.

To understand how this works, we first need to understand how viral pathogens spread through the air and reach new hosts. Let’s dive into this issue in further detail.

The ABCs of Aerosols

Aerosols, which are microscopic droplets of moisture naturally dispersed by humans, tend to contain a high viral load from those who are sick, even if they’re asymptomatic. The trouble in school environments is, whenever children play, speak or even exhale, they’re emitting aerosols into the air. Without proper humidity control in place, it can be difficult to reduce the spread of pathogens, especially during flu season.

Why Does Proper Humidity Control Matter?

Maintaining between 40 and 60 percent relative humidity is essential, but why? Well, it’s not only the ideal range for sufficient hair, skin and eye hydration but also for the weight of aerosols. With just enough moisture weight, aerosols tend to settle much more quickly. In this instance, if a student coughs, the aerosols they produce won’t travel as far, helping limit the spread of viral pathogens. This is why we see relative humidity standards implemented in some public facilities and sensitive environments; proper humidity control means proper airborne infection control.

On the Immune System

An environment with an automated, efficient humidifier makes it easier on children and staff within the school facility. Less susceptible to irritation and subsequent infections, controlling indoor air quality parameters helps to promote a healthier immune system, cutting down on absenteeism while potentially also reducing the risk of complications if someone does get sick.

Other Benefits

Implementing an indoor humidifier solution for a school environment – one that’s ideal for the required load capacity and leaves no “dead zones” – is also a great way to suppress dust and other allergens, which can otherwise cause discomfort or health complications in students and teachers. The potential for electrostatic discharges is eliminated as well, protecting building occupants as well as computers, their hard drives, and other sensitive components. To top it off, proper humidity control is conducive to an environment with fewer irritation triggers and optimal hydration, encouraging improved focus and student engagement.

The only way to effectively improve airborne infection control in schools is to implement a consistent, and dependable means of indoor relative humidity control. Products such as Condair high-efficiency commercial humidifiers are ideal for such use cases, readily available in a variety of load capacities to suit your needs. That way, your teachers can focus on delivering the best lessons ever, helping students deepen their collective well of knowledge while minimizing airborne infection risks.
