Bipolar Ionization Efficacy

The recognition of bipolar ionization efficacy to improve indoor air quality goes back decades. Since the 1960s, ASHRAE has touted the benefits of ionization in breaking down harmful VOCs and destroying pathogens and viruses. More recently, ionization has proven that clean, disinfected air helps prevent the spread of the SARS-CoV-2 virus which causes COVID-19.

Bipolar Ionization Efficacy

The effectiveness of bipolar ionization in cleaning air is nothing new. As far back as 1966, the ASHRAE Journal was promoting the benefits of ionization. Even at that time, hundreds of studies already proved the value of ionization in improving indoor air quality.

More recently, a controlled experiment conducted by the Kitasato Research Center for Environmental Science based in Tokyo Japan proved the efficacy of bipolar ionization in destroying pathogens. Their study showed a reduction of the H1N1 virus after only one hour of ionization.

Fighting COVID-19 with Ionization

As we’ve seen, studies prove that bipolar ionization is effective in fighting viruses such as H1N1 influenza and H5N1 avian influenza (bird flu). But it also deactivates the coronavirus making it harmless. For example, a recent study by Madrid-based HVAC company Tayra and backed by the Spanish Ministry of Defense Biological Laboratory proved that PURE-Plasma bipolar ionization technology reduces viral spread by almost 100 percent. The study used a Plasma Air Ionizer and a substitute for the coronavirus (MS2 Bacteriophage) to get a 99 percent reduction of the virus after ten minutes of ionization.

The coronavirus spreads through tiny water droplets that get breathed into the lungs. In addition to the respiratory droplets, growing evidence suggests that aerosol transmission is also a mode of transmission. This means that the virus contained in droplets stays in the air for much longer than previously thought. If cleaner air reduces the spread of the virus, then ionization is an important tool in the fight against COVID-19.

How PURE-Plasma Improves IAQ

A harmless pathogen no longer spreads infection. Bipolar ionization is effective in making viruses inactive. PURE-Plasma technology also reduces pathogens such as Staph and E. coli. Three PURE-Plasma products offer the best results for destroying pathogens. Needlepoint, brush, and tube-style ionizers kill viruses but also reduce dust, pollen, and smoke and get rid of odors too.

PURE-Plasma ionizers mounted on HVAC ductwork or in the air handler release positive and negative ions. These ions cluster around the virus and break it down. The virus alone is too small to get caught in most filtration systems. However, when inside a cluster they are easier to catch and remove. Bipolar ionization is effective in attacking viruses before they enter shared spaces. This has enormous benefits for hotels, schools, and hospitals. In fact, all commercial buildings benefit from cleaner air. It creates healthier environments for staff and visitors.
