In the aftermath of COVID, people have become hypersensitive to germs, quality air and cleanliness. In fact, the Bradley Corp found that 60% of Americans are extremely or quite concerned about catching the flu or becoming sick, compared to just 32% who felt that way only four years ago.
Because air purifiers can capture and kill airborne pollutants like bacteria, virus particles, dust, allergens, mold spores and more, many organizations are turning to air purifiers to protect their employees—and the people they serve—as well as meet the new standards of cleanliness.
If you’re asking yourself:
We have the answers!
The truth is, there are actually four different ways air purifiers can clean indoor air and each device may use one or more of these methods:
Air purifiers that use a HEPA filter work by using an internal fan to suck air into the machine and pass it through the filter. As air goes through the HEPA filter, airborne pollutants get trapped inside the dense material, while clean air flows out the other side for you to breathe.
The great thing about HEPA filters is that they can capture fine pollutants down to 0.3 microns in size which includes things like dust, allergens, bacteria, mold spores, and visible smoke.
Air purifiers that use an activated carbon filter also use an internal fan to pull air through the filter to trap contaminants. The material, however, is completely different than a HEPA filter. Activated carbon is a specially treated medium that’s very porous, which allows it to adsorb impurities from the air. These filters are specifically designed to adsorb odors, vapors and gasses from things like smoke, cooking, chemicals, paints and other volatile organic compounds.
An ionizer is another method for cleaning indoor air, but it doesn’t use any filters. They work by emitting negatively charged ions into the air that latch onto pollutants. This bond causes these particles to become too heavy to remain in the air and those clusters fall onto the ground and other surrounding surfaces.
Ionizers are great for removing a variety of airborne pollutants such as dust, allergens, smoke particles, and mold. But these particles remain inside the room until you vacuum them up or wipe them off surfaces.
This feature uses short-wave ultraviolet light to inactivate airborne pathogens and microorganisms. As air passes by an ultraviolet light, it disinfects the air by means of germicidal irradiation. Ultraviolet lights are the only kind of air purification technology that can kill airborne bacteria and viruses.
With so many air purifying options, it might be hard to determine which purifier is right for you. Here’s a great starting point: how big is your space?
