Antimicrobial Antibacterial

Antimicrobial Definition & What is the Difference Between Antimicrobial and Antibacterial?

Antimicrobials can kill or prevent the spread of microorganisms, including bacteria, viruses, and fungi, on surfaces. Many substances, including disinfectants, can be antimicrobial, though the term itself is not indicative of performance. Simply put, antimicrobial agents are products that kill or stop the growth of microorganisms. Although they are primarily used to remove buildups of dangerous or harmful microorganisms like bacteria, viruses or fungi that form on surfaces, antimicrobial agents actually have uses within some animals and in human medicine, as well.

Products that use antimicrobials keep workplaces, residential spaces and other surfaces like bathrooms clean, while also having their uses in healthcare and industrial facilities. Antimicrobials are capable of aiding in treating severe infections and protecting important infrastructure like water systems from growths of microorganisms.

The biggest difference between antimicrobial agents and antibacterials are the types of microorganisms they work against. While antimicrobial technology is effective against viruses, bacteria, and fungi, antibacterial technology is only effective against a broad spectrum of harmful bacteria. Additionally, antimicrobial technology continues to inhibit the growth of microbes on surfaces for longer periods of time than antibacterial technology.  

There has been widespread speculation on antimicrobial technology and scientists have studied whether or not usage of antimicrobials creates resistant strains of microorganisms – although, they have not been able to completely agree. 

However, there is good evidence that the major category of disinfectants, quaternary ammonium chlorides (quats), lose their effectiveness against some organisms over time. This is a problem in medical settings in particular. In addition, some organisms, depending on their structure, are inherently resistant to some disinfectants.

How Do I Know My UVGI Measures are Working?

For years, scientists have known germicidal UV-C disinfection as an effective method for disinfecting air, water, and nonporous surfaces. In fact, UVGI light systems have been widely used since the 1980s to control tuberculosis in healthcare environments. Although strictly air filtration is not enough to protect your facility from airborne viruses like SARS-CoV-2, implementing UVGI lighting technology into your HVAC ducts kills not only contaminants like dirt, mold and fungi, but also the other buildups that allow viruses to easily spread throughout the air of your facility. The ability to perform not only surface disinfection but also air disinfection makes UVGI an extremely valuable tool in ensuring surface and air safety in healthcare and industrial environments, where cleanliness matters the absolute most.

EcoGroup USA’s comprehensive IAQ infrastructure combines strong, energy-efficient air filtration with UV-C UVGI light technologies to protect the air that your facility and staff breathes each day.

When you install ECOSENSE Platforms into your facility, our innovative executive dashboards and reporting modules will provide you with a clear picture of whether your safety measures, including UV-C lamps, are properly cleaning your air. While UV-C lamps require annual to bi-annual maintenance, you can enjoy a lifetime warranty on all of our UV lighting system parts (not including lamps).

UV Light Room

Does UV Light Have Negative Effects on Surrounding Materials?

The effects of UV light have been studied for nearly a century at this point. Although the current focus surrounding research on the technology may be centered around its effects in mitigating the effects of COVID-19, industry leaders have been studying the capacity of UV light to act as a disinfectant agent since the early 1900’s, during which UV technologies became commercially available. Although UV light may negatively affect the human body in places like the eyes, skin and teeth if an individual is exposed to its associated radiation for too long, implementing UV-C lighting into the HVAC infrastructure of your facility provides extremely little risk, as direct exposure is the only time that any health risks present themselves.

The power of UV-C light as a disinfecting technology in HVAC systems ultimately does not come without its risks to the surfaces and areas contained within HVAC ducts. While long-term exposure to UV-C can damage plastic materials, we are proud to provide our customers with UV-C products that provide an ideal balance between germicidal effectiveness without damaging sensitive materials inside of your HVAC system.

UV Lamp FAQ – Power Usage, Ozone, Replacement

Depending on the manufacturer, UV lamps generally need to be replaced every one to two years (or every 9,000 to 18,000 hours)The effectiveness of UV lamps diminishes over time, and even though your lamp may still be glowing after its one or two-year designation, it is still vital to replace it. On our products, “1 year” and “2 year” lamp designations refer to effective output and now when the light will burn out. Replacement bulbs are available and will be provided by your HVAC technician. 

Most ultraviolet lamps are designed to run continuously and do not need to be switched on and off. Our UV lighting systems are intended to run for 24 hours a day, as continuously turning the lamps on and off may shorten the life of the lamp(s).  Germicidal lamps only produce as much heat as fluorescent lamps; therefore, you do not need to worry about your HVAC’s UV lamp getting too hot or overheating.

In addition, some germicidal UV-C lamps emit ozone; however, we are proud to provide our customers with ozone-free lamps.

UV Lamps Mold

Will My Germicidal UV Lamps Take Care of Mold?

UV-C lamps are incredibly powerful in combatting buildups of mold, fungi, contaminants and bacteria buildups that form what’s known as biofilm – a slimy layer of bacteria that forms on HVAC infrastructure surfaces, limiting the effectiveness of your air filtration systems. UV-C lamps are a strong technology that is capable of combatting the formation of […]
