What is the air quality standard for ozone?

Ozone (O3) is a gas which, in the atmosphere protects us from UV radiation and is beneficial to have high quantities of. However, at ground level, ozone is a pollutant. Ground-level ozone (Tropospheric ozone) is not emitted directly into the air but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC). Tropospheric ozone is emitted by cars, power plants, industrial boilers, refineries, chemical plants, and other sources chemically react in the presence of sunlight. Additionally, the Environmental Protection Agency (EPA) says that “ozone is most likely to reach unhealthy levels on hot sunny days in urban environments, but can still reach high levels during colder months. Ozone can also be transported long distances by wind, so even rural areas can experience high ozone levels.” 

The Clean Air Act, therefore, requires the EPA to set national air quality standards (NAAQS) for ozone and five other pollutants (particulate matter, nitrogen oxides, carbon monoxide, sulphur dioxide and lead) considered harmful to public health and the environment. 

Referring to the ozone data on Environmental Protection Agency AirWatch using air quality categories, the aim is to maintain the air quality category at ‘Good’, requiring for there to be less than 50 parts per billion of ozone averaged over 1 hour qualifying the public health and environment to make no changes to their normal outdoor activities. 

How does PuraAir utilise ozone?

The UVC Series 1000 is PuraAir’s high quality and high-performance commercial air quality solutions. It eliminates unwanted odours and destroys bacteria and viruses by utilising an ultraviolet ray UVC germicidal lamp and using UV Lamp ozone generating technologies. 

Here are some ozone features it occupies: 



• The LED Light indicator panel displays the system settings and indicates when the lamps are due for replacement, while the Ozone Source indicates the ozone level currently in operation. 
• The ACC (Adaptive Command Control) is adjusted to achieve the correct ozone levels to suit each customised application. This function is available while using the remote-control option or can be adjusted at the time of installation or when servicing the system. 
• The HFADS (High Flow Air Distribution System) is exclusive to the PuraAir UVC Series. The HFADS the maintenance-free turbine blower has been designed for high output with whisper-quiet operation. The 25mm outlets deliver a high volume of ozone to ensure effective odour control. The turbine blower combines the HFADS and is engineered to manage the cooling of the equipment within the cabinet while eliminating odours and cleaning the air at the same time. 

One major use of ozone comes into play with the air sanitation process. This process begins with the continuous filtering of the airborne dust particles in the air through active carbon filters drawing in the unwanted odours from the area that is being treated. When the odour is drawn in through the filters, they enter the UVC germicidal light chamber where the odour control process begins. The micro-organisms come in contact with the UVC germicidal light wave, it then changes their DNA and destroys them by a process called irradiation. 

The advanced stage of the air sanitation process is when ozone (O3) is produced by the UV light waves. It is distributed by a high flow air distribution system to the area that needs to be treated. For example, in a high-rise garbage chute application, the O3 is delivered into the garbage chute and bin where the odour originates; here the building’s garbage chute’s natural updraft carries O3 from the bottom to the top destroying bacteria and viruses. This, therefore, eliminates and prevents unwanted odours from entering the building’s residential or common areas to provide a sanitised environment. 

The reasoning behind the adoption of ozone for cleaning lies in Ozone Oxidation which can be done via reaction with Ozone. It is often used for its disinfecting effect against pathogenic organisms, pathogens, bacteria, viruses and endospores, but also for components such as unwanted colour, odour, and flavours (organic components), or via indirect reactions with OH Radicals. 

As you can see PuraAir’s advanced research and technologies have created odour control and air sanitisation and air scenting products and machinery that any business or space would benefit from. 

The UVC Series 1000 has no ongoing chemicals or storage costs. It has a 100% Australian garbage odour eliminator design, worldwide approvals for use on food (FDA), design rights approved technology and incorporated ACC (Adaptive Command Controls), the UVC Series 1000 provides a healthier environment for you, your guests and customers. 

Additionally, when you invest in the UVC Series 1000 you can be sure to receive the best quality product, one that harbours all the 8 must-have features for your commercial odour control system, ranging from bacteria, virus, mould and fungal spore control. 

Keep your space clean and healthy with the latest technologies equipping ozone air sanitation process and ozone oxidation. The chemical-free, high flow distribution system is low maintenance but high in its UV lamp quality making it energy efficient and quiet while operating.   

Alternatively opt for Pura scent professional scenting systems which enable you to experience the power of scent, whether you are looking for a permanent discrete HVAC installation or a portable vapour system. 

PuraScent is efficient, low maintenance and cost-effective. It can be connected directly to your air conditioning system or fresh air supply for the common area, and a large variety of fragrances are available.
