Clean air is important, and air purifiers are always an excellent addition to indoor areas with high traffic or a high capacity limit. They actively remove airborne bacteria, allergens, and diseases that people bring in throughout the day and greatly contribute to the public’s health and safety when used properly.  There have been recent advancements in air purifying technology, and it has been proven that certain air purifiers now have the ability to help reduce the spread of COVID-19. Since children in school are considered to be among those who are the most at risk of COVID exposure, Airocide® and Scientific Air™ brands of air purifiers are eligible for the Elementary and Secondary School Emergency Relief Fund (ESSER). Here, we will discuss some of the important facts you should know to help you decide which air purifier is the right choice for your classroom.

Size Matters

Before you can decide which covid air purifier is right for you, you will need to determine how hard you will need it to work and how much air you will need it to clean. First, you need to measure the size and volume of the room. Multiply the length of the room by its width to determine its total area, then multiply the area by the height of the room to determine the room’s total volume. Once you’ve confirmed the volume of the room, you can determine how much power you will need for your air purifier to have. The power and efficiency of an air purifier are measured by its Clean Air Delivery Rate (CADR). To calculate the amount of CADR you need, take the total volume of the classroom and multiply it by 5. In this scenario, we choose the number 5 because in a classroom you will want all of the air to be filtered and replaced with clean air at least 5 times per hour in order to efficiently reduce the spread of COVID. 

How To Choose

Now that you’ve determined the size of your classroom and the amount of power you need, now you have to choose your product. There are a variety of options available on the market, but to choose the best air purifier for a classroom, you will need one whose technology has been proven to be energy efficient and the most effective at eliminating COVID-19 particles and other airborne viruses. As we mentioned previously, Airocide® and Scientific Air™ brands of air purifiers are eligible for the federal ESSER funding. Both brands can be used in occupied rooms, are safe, energy efficient, and eliminate odors. Both brands release no harmful emissions, no ozone, and no chemicals. Scientific Air’s HEPA filter uses proprietary 3-stage technology that destroys infections and contaminants, and has been trusted by leading hospitals, healthcare organizations, and commercial building management. Scientific Air can also be portable, which is great for having to be moved from room to room. Airocide’s patented Photocatalytic Oxidation technology completely destroys airborne viruses including COVID and other pathogens. Not only do leading organizations around the world rely on Airocide to keep their customers and employees safe, NASA trusted Airocide to sanitize its International Space Station.
