Every electronic device has the potential to produce a negligible amount of unintentional ozone. The California Air Resource Board (CARB) requires that air cleaning devices do not produce more than 0.05 ppm of ozone.¹ Due to the cost of CARB testing, ActivePure only tests specific units that have a viable business case in California. Every ActivePure unit ever tested under CARB standards has passed the testing and shown negligible or non-existent ozone production. The ActivePure Beyond Guardian Air, for instance, has been shown to produce a peak ozone level of 0.0008 ppm—less than 0.02% of CARB’s permissible limit.²

According to an extensive study³ of ActivePure devices under field conditions, “In all cases, TiO2 levels were found to be below levels of concern”.

Generally, we do not disagree with that, which is why we have combined HEPA filtration with ActivePure Technology in our ActivePure Medical Guardian, which has been cleared by the FDA as a Class II Medical Device for use in healthcare settings. With ActivePure, HEPA filtration units can be materially more effective. Most importantly, ActivePure meets all CDC guidelines for emerging air disinfection technologies. This includes documented data under as-used conditions from multiple third-party sources. Moreover, devices with ActivePure Technology have been shown to meet the CDC recommended UL 2998 Environmental Claim Validation Procedure (ECVP) for Zero Ozone Emissions.

ActivePure is an air purification system, not a filter.

Corsi-Rosenthal boxes rely on filters and are prone to assembly errors or other issues that may impact efficacy.

One must also consider space. The very largest ActivePure machine (designed for large public spaces such as gymnasiums) takes up a little over 2 cubic feet of space. A Corsi-Rosenthal box with a 20-inch box fan would take up over twice that. Because of this, ActivePure Technology can be installed in elevators, buses, cars, and right inside HVAC systems, while Corsi-Rosenthal boxes cannot. Additionally, ActivePure Technology is produced in ISO qualified factories; it is not homemade and susceptible to novice assembly mistakes.

ActivePure is not a ventilation solution.

• Ventilation is generally a good remedy to dilute pathogens; with some caveats
• Increasing ventilation can be expensive by increasing the amount of outdoor air needing to be heated or cooled; this increases energy costs and carbon footprint
• Outdoor air can also contain contaminants; bringing more outdoor air in at the wrong time of day can potentially increase particulate matter⁵
• Many older HVAC systems are not designed to materially increase ventilation (or filtration), as a result, increasing ventilation and filtration in indoor spaces may require the replacement of HVAC systems

ActivePure is not PCO technology.

• ActivePure is an advanced photohydrolysis technology—not PCO
• Early generation PCO-type air cleaners can generate ozone and VOC gases,⁶ potentially making them unsafe to use in indoor environments—ActivePure does not do this

ActivePure is not UVGI purification.

• Robot-style Whole Room UV light can be effective as a one-time treatment, but has some key disadvantages
• Whole Room UV only treats what is directly exposed to the UV light
• Whole Room UV can only be used in unoccupied rooms as it is harmful to the eyes and skin
• Whole Room UV does nothing to help in occupied rooms if new pathogens are being introduced to the space
• UVGI is dependent on the contaminants making their way into direct exposure with the UV light
• It is not easy to calibrate a UVGI system so that it has enough time to inactivate pathogens during the time they are exposed
• UVGI does not reduce unwanted gases⁷

The ActivePure Surface & Air Guardian⁸ successfully inactivated airborne SARS-CoV-2 viral particles to below the detectable limits in 1 minute under laboratory conditions.⁹ In real-world application, the same ActivePure Technology was deployed in skilled nursing facilities and observed a 94% reduction in COVID-19 cases among residents over a 6-month period, compared to a 46% increase at matched control facilities that did not receive the technology.¹⁰

Unaffiliated independent laboratories have completed extensive testing to prove that devices with ActivePure Technology—when used as directed—can help reduce many airborne contaminants. For instance: the ActivePure/Aerus Medical Guardian eliminated 99.99% of Staphylococcus epidermidis Gram-positive Bacteria, Aspergillus niger fungal mold, and Bacillus globigii bacterial mold within 60 minutes or less. See the full list of tested pathogens.

The ActivePure Induct Guardian series was the subject of a clinical study, peer-reviewed and published by the American Journal of Infection Control (AJIC). It took place in two separate hospital environments and was proven to reduce methicillin-resistant Staphylococcus aureus (MRSA) and fungi on surfaces and floors by 96-99%. Additional observations showed reductions in healthcare-associated infections (HAIs) by 70-71% over 12-21 months.¹¹ Learn more about this peer-reviewed study.

Common guidance suggests increasing ventilation and filtration while only briefly acknowledging what kind of economic impact this might have on energy costs, existing infrastructure, and pathogen reduction outcomes. Building ventilation is a complicated field that requires balancing energy efficiency, temperature, humidity, indoor contaminants, and outdoor contaminants. Regarding the latter, bringing in outside air at the wrong time of day might increase contaminants indoors. ActivePure can provide sensors to monitor and optimize indoor air and the introduction of ventilated outdoor air.

Very quickly. Each induct unit can be installed in less than an hour by your in-house maintenance personnel. Our portable units require no HVAC modifications at all and can begin operating immediately.

Very little. When used as directed, we recommend replacing ActivePure cells once a year; this is comparable to the maintenance of other cleaning technologies. HEPA filters and activated carbon filters in ActivePure units need replacement about once every 6 to 12 months. All these replacements can be performed by in-house personnel in a matter of minutes.

ActivePure devices don’t require installing high-MERV filters which can strain the HVAC system and increase energy costs. Also, most units use less than an amp of power. ActivePure Technology, properly installed and monitored, may also allow for the reduction of heated and cooled outdoor air ventilation and on MERV 12-14 filters.

By installing a solution with a low-carbon footprint that does not leave residual surface chemicals, ActivePure Technology can be an integral part of your organization’s energy and environmental goals. With ActivePure Technology, many clients reduce the ventilation and filtration costs, and attendant energy usage. Your commitment to employee/staff/customer/student peace of mind may also boost your reputation for good governance and social responsibility.
