For the Air Disinfection Biosecurity (patent pending) systems with controllers, the sensor head needs to be replaced every 18 to 24 months. On the main units, the filter, and the PVC chamber with metal mesh should be replaced annually. Maintaining these components this way should ensure your ADB system will work for years to come.
ADB has been installed in the USA since 2008, and in that time, tens of thousands of units have been utilized in over 1,000 installations.

Below is a partial list of US installs:
PathogenFocus units comply with the requirements of the UL2998 "Zero Ozone" standard.

The ozone byproduct created by these ADB units averages less than 2 parts per billion (ppb) which is well under the limits set by UL #867, the US Environmental Protection Agency (EPA), California Air Resources Board (CARB), the Food and Drug Administration (FDA) and the Occupational Safety and Health Administration (OSHA), among others. These agencies have limits ranging from 50 to 100 ppb.

The ADB 7000 series meets California ozone emissions limit - CARB certified.

Less than 50 PPB is the requirement of the following organizations:
- Underwriters' Laboratories - UL #867
- U.S. Food And Drug Administration (FDA)
- U.S. Environmental Protection Agency (EPA)
- California Air Resources Board (CARB)

Less than 75 PPB is the requirement of the following:
- National Ambient Air Quality Standard (NAAQS)

Less than 100 PPB is the requirement of the following:
- Occupational Safety And Health Administration (OSHA)
- National Institute Of Occupational Safety And Health (NIOSH)
Air Disinfection Biosecurity (ADB) technology is based on a Modulated Barrier Discharge (MDBD) system with proprietary custom-made power modules. These power modules produce a specific modulated frequency signal and controlled pulses that stabilize a safe blend of highly reactive molecules, which includes hydrogen peroxide. Combined with ADB's proprietary design of materials, shape and arrangement of the electrodes, this produces a consistent electric field that in turn causes a partial activation of a portion of oxygen molecules found in ambient air through a reaction with the surrounding environment's gases. This combination of oxygen by-products are the highly reactive molecules capable of traveling in the air, inactivating simple organisms such as airborne and surface-level viruses, bacteria, mold spores, fungi, and other microorganisms. Their protein jackets are broken down, interrupting the cellular structure, damaging the RNA and DNA, thus rendering them inactive.
With Air Disinfection Biosecurity systems, the transmission of viruses can be significantly minimized by the fact that airborne viruses are inactivated so quickly. Airborne viruses such as SARS-CoV-2 are reduced by about 90 percent in 16 seconds, and by 99.9 percent in 30 seconds. The typical person exhales about 0.25 cubic feet of air in one minute, and about 0.07 cubic feet in the 16 seconds required for the ADB system to inactivate 90 percent of the virus in that volume of air. This leaves only 0.007 cubic feet of infected air that can possibly create transmission. Fourteen seconds later, even that is virtually all eliminated, with the elimination percentage being 99.9 percent in 30 seconds. 0.007 cubic feet is the equivalent of a cube about 2.5 inches on each side being disbursed into the cubic volume of the room, then reduced to virtually zero virus in 14 more seconds. The net result of this neutralization would allow for virtually no contagion.
Yes!

Absolutely. This is one of the great advantages of this system - it works while you and others are present (which is when you need it most) - and it works perfectly safely and effectively. ADB meets US Department of Agriculture National Organic Standard sub-type "Sanitizers."
No. ADB utilizes a proprietary Modulated Dielectric Barrier Discharge technology to create a non-thermal plasma inside the unit's chamber. Highly reactive molecules are then dispersed from the chamber with specific properties. While many air purification products came to market in response to the pandemic, ADB has a decades-long history of use as a highly effective surface and air disinfectant in many industries including healthcare, food processing, produce, agriculture, commercial buildings, and more.
Yes. Air Disinfection Biosecurity is a scientifically validated technology, with supporting evaluation studies from the USDA, Kansas State Food Science Institute, and many other independent laboratories. Certifications also include Eurofins (no harmful byproducts generated), Blue Heaven Technologies, CE (European Communion electrical safety), SGS, U.S. Environmental Protection Agency (EPA) registered establishments #90193-CA-1 and #90193-CHL-1, and USDA National Organic Standards' - Registration #2857 - sub-type "Sanitizers." The 7000-AF series meets UL867 standard.

These ADB systems have been around for 20 years and are in 20,000 installations worldwide. They have been installed in the USA since 2008, and in that time, tens of thousands of units have been utilized in over 1,000 installations. ADB has been very well vetted during that time.
Air Disinfection Biosecurity (ADB) technology is based on a Modulated Dielectric Barrier Discharge (MDBD) system with proprietary custom-made power modules. These power modules produce a specific modulated frequency signal and controlled pulses that stabilize a safe, consumable chemical-free blend of highly reactive molecules, which include hydrogen peroxide. Combined with ADB's proprietary design of materials, shape and arrangement of the electrodes, this produces a consistent electric field that in turn causes a partial activation of a portion of oxygen molecules found in ambient air through a reaction with the surrounding environment's gases. This combination of oxygen by-products are highly reactive molecules that are capable of traveling through the air, inactivating exposed, simple organisms such as airborne and surface-level viruses, bacteria, mold spores, fungi and other microorganisms. Their protein jackets are broken down, interrupting the cellular structure, damaging the harmful agents' RNA and DNA, thus rendering them inactive.

There is nothing you need to add! The system requires no consumables. It utilizes ambient level oxygen, water vapor and nitrogen naturally occurring within the space to generate the HRM plasma. Once the reaction is complete, the reactive molecules that do not react with microbes return to their non-reactive molecular oxygen, nitrogen and water vapor.
These units are very economical to operate. The portable unit (ADB-P) requires 20 watts. Approximately 30-45 watts is needed for the units that treat 30,000 cubic feet. Spaces up to 155,000 cubic feet would likely require the ADB 7000-8AF unit, which operates at about 55 watts.
Unlike other competing technologies, our approach is applications engineering on each project. All units are calibrated for the application, and range from 2,000 cubic feet up to 155,000 cubic feet for single units, and there are 12 different models that can be combined if necessary. Therefore, a lot of information is required to quote, such as: Do you have an HVAC system or not, what is the cubic feet per minute (CFM) of your air handlers, what is the cubic volume of the room - and more. We have the capability to have projects budgeted on a square-foot basis.
There is a massive focus right now on antiviral technology in the wake of the COVID-19 pandemic. As we stated before, ADB will inactivate SARS-CoV-2 (the novel coronavirus that can lead to COVID-19) quickly and effectively. It also works tremendously against over 99 percent of known bacteria, including MRSA, E. coli and Salmonella.

ADB is also extremely effective in neutralizing molds and mold spores, allergens, fungi and mildews. Candida Auris - a potentially deadly fungus that is often acquired in hospitals - is 99.99 percent eradicated by ADB in about 30 minutes.

Because of its ability to eliminate these irritating pathogens and molds, ADB can also effectively neutralize unpleasant odors.

ADB can eliminate bacterial contamination in foods, and can eliminate other microorganisms that can be harmful and limit the post-harvest life and condition of perishable products. This not only helps prevent potential recalls and people getting sick from eating contaminated products, it also extends the shelf life of meat and produce.

ADB systems have had proven success in horticulture and agriculture applications too. ADB helps with a reduction in losses due to mold, increases shelf-life by neutralizing decay microorganisms, produces firmer heads and stems in certain plants, and reduces ethylene.
The standard warranty is 3 years, but the unit will last 7 to 10 or more years with proper maintenance. The filter and reaction chambers must be replaced annually.
