Technology

ActivePure® is a non-toxic air purification system that greatly improves indoor air quality by providing a non-invasive, continual treatment of the entire facility without chemicals and toxic by-products.

Humidity Consideration

ActivePure requires at least 30% humidity to provide this dry Hydrogen Peroxide. If you live in a dry area (like Arizona), you may need to purchase a humidifier to keep the humidity at an optimal level. Something to keep in mind.

Current Strategies & Limitations

Ultraviolet light treatment has been shown to work well for disinfection of small areas, but not in central ventilation systems. Additionally, the indoor environment may be contaminated with low levels of toxic chemicals such as formaldehyde, styrene, and toluene. Ultraviolet energy does not work well in degrading these chemicals. [1]  UV/UV-C systems have been proven to reduce contaminants by 10-30% [2], but requires downtime for the room, employee training, considerable equipment costs, and can only be used for terminal disinfection when no one is in the room.

 

Hydrogen Peroxide has ample data regarding micro-biocidal activity and reducing HAIs, [3] and Hydrogen Peroxide Vapor (HPV) has a proven effectiveness against C. diff and more, reducing pathogens from 25.6% down to 0%. [4] Disadvantages include considerable downtime to treat rooms (1.5-5 hrs.), time to disassemble the HVAC system, solution dispensing errors, and can only be used for terminal disinfection. [3]

Continuous Non-Toxic Room Decontamination

Because we are not effectively removing the contaminants on a daily basis from patient rooms and those contaminants in those rooms can be a mechanism of transfer of pathogens from the surfaces to patients and can, of course, increase risk of transmission of healthcare associated infections. We would like to have a continually active room decontamination system, so essentially, it continually inactivates organisms and it doesn't interfere with patient care. All people can enter. Staff can enter, patients can be there, and of course, visitors can enter.

Photocatalytic Oxidation (PCO) technology provides one of the most viable solutions to the problem of indoor air contamination by microorganisms and VOCs and as a defense against the threat of contamination of ventilation systems by bioterrorism. The photocatalytic process involves the action of low energy UV light on a catalyst in the presence of water vapor, which generates hydroxyl radicals that destroy microbes and airborne VOCs. [1] Photocatalytic technology is an emerging area that is proving to be effective at decontaminating air and reducing indoor air pollution in ventilation systems. It has been demonstrated successful at removing microorganisms, VOCs, bacteria, and spores, while providing protection against bioterrorism agents. This technology, when combined with a HEPA filter, becomes an effective answer to the indoor air quality problem and can be integrated into central air conditioning systems or used in stand-alone units. [6]

“What we’re looking for essentially, is a dilute Hydrogen Peroxide, a concentration of Hydrogen Peroxide that kills micro-organisms but is not harmful for patients, or of course, staff. How do you get a concentration of Hydrogen Peroxide that’s very low? There’s various technologies that take Oxygen out of the air, you take water out of the air, and you make Hydrogen Peroxide.”

- Dr. William A. Rutala `{`2`}`

ActivePure’s® Radiant Catalytic Ionization (RCI) technology is an enhanced, more intense version of PCO and HPV technologies. RCI incorporates Hydroxyl Radicals (OH), Vapor Hydrogen Peroxide (H2O2), a very low level of (soft) Ozone (O3), and UV-C light.  The PCO process also has the ability to reduce Ozone levels up to 50% while creating Hydroxyl Radicals and super oxide ions. The catalyst of Titanium Dioxide (TiO2) and other metals reduces EPIs, VOCs, and other HAIs by >99.9% on a continuous basis. Improving on PCO’s effectiveness, RCI reduces the H2Orate down to .05 ppm, and continuously treats the entire facility through the HVAC system, attacking surface and airborne contaminants instantly as well as porous materials like curtains, cushions and clothes.

 

Titanium Dioxide (TiO2) used in Photocatalysis processes is non-toxic, chemically stable, available at a reasonable cost, and capable of repeated use without substantial loss of catalytic ability. The mechanism of bacterial action of TiO2 Photocatalysis, is attributed to the combination of cell membrane damage and further oxidative attack of internal cellular components, ultimately resulting in cell death. [7,8] TiO2 is non-toxic and has been approved by the American Food and Drug Administration for use in human food, drugs, cosmetics, and food contact materials. [7,9]

What Our Partners Say

"Beth is awesome, is always willing to work with and support her customers. We have been using ActivePure Technology in our ambulances since 2013, and are very impressed with the results."


Brad Mackey
Paramedic, Field Supervisor
Mercy EMS Camden County

"What a great job Beth has done for our organization. She was very professional and knowledgeable as we work to resolve our issue. I highly recommending Beth."


Ken O'Kelley, Vice President
YMCA Camping Services

"Mercy EMS began using activTek Health Solutions years ago. Our new and remounted ambulance specs were updated to include installation of the AP5 device. We made this decision following the testing by our Infection Control dept. of the patient compartment and the various equipment. It was obvious based on that testing that we could improve and the AP5 was a quick and achievable solution. We realized immediate improvement in our ambulances with the technology installed. The AP5 works quickly and is appreciated by our co-workers who feel better about the working environment in our ambulances. I would recommend Beth Krah and her team to an EMS agency considering improvement methods for their ambulances as it relates to infection control."


Bob Patterson, Executive Director
MERCY EMS - Springfield

"We're proud to have raised the standard for pro-active infection control in the ambulances we up fit and remount. We are putting AP5s in our in-stock remounted ambulances as a value-added feature that will positively affect the work environment for Paramedics and EMTs. We encourage all of our customers to take advantage of this system for the health of their employees and their patients."

Dave Shuell, Remount Project Manager
Emergency Vehicles Plus

"We were absolutely blown away by the effects of ActivePure. Very impressive, especially in the shower tent. We noticed a great improvement in only 30 minutes!"
