Cleaner air is a common talking point these days. Whether it has to do with carbon emissions and their effect on greenhouse gases or not, clean and healthy air is better for everyone. The wildfires out west have proven how devastating “hazardous air quality” can be. Coupled with the ongoing fears caused by the Delta variant, this indicates that air purification matters. What are the various types of room air purifiers?
High-Efficiency Particulate Air
This technology hinges on air filters. They are the traditional method used for trapping particles that would otherwise bring down IAQ. HEPA filters specialize in stopping mold spores and invisible germs. While these room air purifiers are most effective at catching particles, they can’t eliminate bad odors, chemical fumes, or toxic gases.
Activated Carbon Purification
Many HEPA filters work in tandem with activated carbon room purifiers. A special processing technique transforms carbon into a porous material. This technique allows the carbon to purify the air more effectively. Originally, activated carbon was used to purify water and remove the color from sugar. But then, during WWI, it became apparent that activated carbon could be used in gas masks as well. So any potential air contaminants such as chemicals, gases, tobacco smoke, and foul odors are captured but not released into the circulation cycle.
It’s easy to think that UV light is harmful and nothing more. However, when it is used in room air purifiers, the light is amazingly effective. It kills off bacteria and viruses. Meanwhile, UV lamps emit rays that destroy microorganisms via cellular or genetic damage. Even so, the lamp has to be inspected, maintained, and replaced as needed. Follow all manufacturer’s instructions. Then be sure to add a filter to the system. This strategy makes all of your filters more powerful.
Negatively Charged Ions
Do you know what bipolar ionization is? By now, you should be somewhat familiar with this term. Negatively charged ions make a noticeable difference when your goal is to purge the air of any particulates. Chemical injections cleanse the air by making particles too heavy to continue floating. Please note that these two concepts are not the same; it’s much smarter to use needlepoint bi-polar ionization than deploy negatively charged ions.
