Frequently Asked Questions

What types of airborne contaminates will AiroCide® Photocatalytic Air Purifying Systems eliminate?

AiroCide air purifiers completely destroy airborne bacteria, mold, fungi, viruses, volatile organic compounds (VOC’s like ethylene gas) & many odors.

Do the systems produce Ozone?

No, not only do the systems not PRODUCE ozone, but they REMOVE ozone by converting it to oxygen.

What makes AiroCide air purifiers different from other air cleaners?

Two distinct features separate AiroCide air purifiers from competitors. First, it is not a filtering system. The technology is based on immediate destruction of airborne contaminates – not trapping or collecting them in a filter. Second, many other air cleaners and purifiers produce some type of Ozone, or 03, that is emitted into the air, though many are disguised ionizers or other terms. AiroCide air purifiers do not produce any ozone and are the only air cleaners to completely destroy the pathogens that pass through a Photocatalytic Oxidation (PCO) chamber.

What makes the Photocatalytic Oxidation technology different than others on the market?

Other attempts at using Titanium Dioxide (TiO2) coated materials that claim oxidation or pathogen destruction have proven ineffective because of slow oxidation efficiency. The intended catalysts in these cases are either not photocatalytically active and/or delaminate (or split into thin layers) easily. The patented AiroCide technology utilizes a nano particle science to make a titanium oxide membrane that is photocatalytically active, which also binds to the applied surface(s) without delaminating. Nanotechnology comprises technological developments on the nanometer scale, usually 0.1 to 100 nm, or ten thousand times smaller than the width of a human hair.

Can AiroCide photocatalytic air purifiers eliminate ozone already existing in a room?

Tests have demonstrated that the oxidation reaction inherent in the Photocatalytic Oxidation (PCO) chamber will convert ozone to oxygen. So not only do AiroCide air purifiers differ from many other air purifiers by not generating, but they also help eliminate ozone produced by other sources in the environment.

Will it help me with my allergies/asthma?

Many of the common and recognized airborne triggers of chronic respiratory ailments like allergies and asthma are easily killed and removed, such as molds, fungi, pet dander, and dust mites.

Will it eliminate small contaminants and gaseous chemicals or VOC’s?

The technology is not limited by a particle’s size or properties other than its chemical makeup. If an airborne contaminant is organic it will be broken down leaving only carbon dioxide and water vapor.

What types of businesses and industries use AiroCide air purifying technology?

Applications range from quality control and food safety in perishable products and food processing industries to medical- healthcare (AiroCide air purifying systems are FDA Class II listed medical devices) and many other commercial, government and residential indoor air quality uses. Additional specific applications for infection control and terrorism preparedness functions also exist.

How does it work?

The patented technology combines two known pathogen-killing techniques, Photocatalytic oxidation (PCO) and ultraviolet light to destroy harmful airborne microbes. Titanium dioxide (TiO2) is the photocatalyst used in the AiroCide air purifying systems. When this material is irradiated with the ultraviolet photons from the lamps inside, hydroxyl radicals are formed, which oxidize (reduce to trace elements of carbon dioxide and water) volatile organic compounds (VOC’s) adsorbed on the catalyst surface. They will also kill and decompose airborne pathogens. AiroCide air purifying systems produce no ozone and is not a filtering system.

Are there any filters to replace?

AiroCide air purifiers are not a filtering system and there are no filter media to replace. A fan protective element protects the inner workings of the device from large, bulk particulates. In adverse environmental conditions, incidental removal of such particles may be required.

Does the catalyst have to be replaced?

Since the catalyst is non-depleting (is not used up) and self cleaning (a process called mineralization) in the photocatalytic reaction the catalyst will last for the life of the air purifier. The catalyst material simply causes the reaction but is not chemically oxidized (or “used up”).

What maintenance is required?

The only maintenance required is annual replacement of the ultraviolet lamps.

How much energy do the system use?

The power consumed by the largest model, ACS-100, is equivalent to 3 – 100 watt standard light bulbs; a typical cost, depending on geographic area, is approximately $1 a day.

How is the unit mounted in the room? Does it come with mounting hardware?

The units can be mounted to either the ceiling or the wall. Each unit is shipped with mounting hardware that is used to attach to anchoring studs or beams depending on location.

Is there protection against a power surge?

A circuit breaker that opens upon an amperage surge is included in the circuitry for protection of the electronics as well as shutting down the unit should there be a power malfunction.

Do I need a service person to change ultraviolet lamps or can I do it myself?

Lamp change is very easy and requires no special tools or skills. The cover is removed to find access to the lamp connectors and grommets. Electrical “quick connects” are easily unplugged and lamp pulled out of a protective sleeve allowing replacements to slide in and be reconnected on each end.

Can I place the unit in a closet or concealed space in a home or office?

For AiroCide air purifiers to work effectively the space where it is placed needs to have inlet and return air via the central HVAC system otherwise the closet or isolated space will be the only volume of air purified. The central HVAC system in your home or office needs to blend and mix the air as it continuously does while it heats and cools your environment.

If there is a fan to move air, how much noise does it generate?

Yes, a fan draws air into and through the PCO chamber. The sounds of the air movement and fan spinning can be heard but noise levels are far less than most air “filtering” devices. The actual decibel level of noise is close to conversational levels.
