Laboratory Tests: Air Purifier Technologies Against Viruses & Bacteria

Air Purifiers for Viruses and Bacteria

Indoor air and surfaces are full of viruses and bacteria. As people come in and out of rooms, touch surfaces, cough and sneeze, the air fills with tiny particles that can cause sickness. From immediate irritation to contracting contagious diseases, this is a serious public and personal health concern. Air purifiers can reduce pathogenic organisms in the air and on surfaces.

There are two core ionization technologies that can impact viruses and bacteria:

  1. AHPCO Ionization
  2. Bi-polar Ionization

These methods are rooted in scientific principles and leverage cutting-edge technology to clean the air.

Read on to learn more about these important technologies and the studies that prove their effectiveness.

AHPCO Ionization: Overview

Advanced Hydrated Photocatalytic Oxidation, or AHPCO, is a proprietary photocatalyst which works to maximize safe, effective ion output. At Air Oasis, we have leveraged this complex technology, originally developed by NASA, and use it in our air purifiers.

Put simply, this process follows these steps (see accompanying illustration below):

  1. UV light is shined on a photocatalyst
  2. The water molecules in the air activate and reorganize
  3. Ions, such as H202, are produced
  4. These ions interact with single-cell contaminants, including bacteria and viruses
  5. Bacteria and viruses are deactivated: RNA and DNA are interrupted to stop their reproduction

This deactivation at a molecular level is the power of AHPCO ionization.

STUDY: MERS Coronavirus and AHPCO Ionization

Laboratory tests were conducted to measure the virucidal efficacy of Air Oasis’s AHPCO technology on Middle East Respiratory Syndrome Coronavirus (MERS-CoV).

The virus was dried on Petri dish glass plates in ambient temperature. These were positioned vertically, with the virus sample facing the device, about five centimeters away. The virus plates were measured at one hour, two-hour and-four hour increments. The Air Oasis technology test device functioned according to safety and manufacturer specifications.

  1. Within one hour, the virus was reduced by 99.792%
  2. Within two hours, the virus was reduced by 99.948%
  3. Within four hours, the virus was reduced by 99.997%

STUDY: Airborne Viruses and AHPCO Ionization

Another lab study was conducted to test the removal efficiency of the Air Oasis 3000G3 for airborne viruses. This study took place in a test chamber that was 25 cubic meters in size. Effectiveness was evaluated according to the Japan Electrical Manufacturers’ Association standard JEM 1467 for household air cleaners. 

The test virus was sprayed into a chamber for 15 minutes. The standard for effectiveness required a two-digit reduction within 90 minutes. The Air Oasis air purifier caused a net reduction rate of 99.5%.

Bi-Polar Ionization: Overview

Bi-Polar ionization may be referred to as cold plasma ionization.  Two charged poles, one negative and one positive use low-voltage electricity to split H20 water vapor, creating positively charged ions and negatively charged ions. As with AHPCO, the virus and bacteria are prevented from spreading because their RNA and DNA are interrupted by these ions. This occurs with contaminants that are airborne and those on surfaces like countertops, tables, and door handles.

It also helps clear the air of airborne particulate matter like dust, dander, pollen, and mold spores. This occurs because airborne charged particles attract to one another, trapping other particles in the process until they are too heavy to float and fall to surfaces to be cleaned.

Another positive outcome of bi-polar ionization is a reduction in static electricity in the treated area.

Here are the steps for bi-polar ionization:

  1. Water vapor is separated into positive hydrogen and negative oxygen ions
  2. These ions interact with single-cell contaminants, including bacteria and viruses
  3. Bacteria and viruses spread more slowly due to RNA and DNA interruptions.

STUDY: Reduce H1N1 Using iAdaptAir

A scientific study evaluated the inactivation efficacy of the Air Oasis air sanitizing device against the airborne Influenza A H1N1 virus. The iAdaptAir was remotely controlled for this test. The virus load was created according to lab specifications. Upon exposure, the rate of reduction was calculated. The results showed that, within 20 minutes, the viral load had reduced by 99.99%. The iAdaptAir was proven effective at inactivating the virus.

STUDY: MRSA Using Bi-Polar 2400

In this study, the challenge bacteria was Methicillin Resistant Staphylococcus aureus, or MRSA. The testing procedure was set to determine if the Bi-Polar technology could disinfect airborne bacteria. A fan and two ionizers were placed in the space. Aerosolized solution with bacteria was released into the place and samples were taken at one minute, five minutes, 15 minutes and 30 minutes. Accounting for the natural rate of decay, after 30 minutes, the Bi-Polar 2400 reduced MRSA by 96.24%.

STUDY: Eliminate E. coli Using Bi-Polar 2400

EMSL Analytical performed this study at the Cinnaminson Microbiology Laboratory. Escherichia coli, or E. coli, was released into a test chamber. This chamber was disinfected prior to use and equipped with a fan and two ionizers. An aerosolized release of E. coli ran for 28 minutes (a total of 5mL). Organism collection showed that, after sixty minutes, the Bi-Polar 2400 had reduced E. coli by 99.23%.
