“It’s impossible to say any one measure will reduce the risk by 100 per cent, but the air purifiers if used correctly, would dramatically decrease the risk. They should be a standard part of the layers of protection for every hotel in Australia.” - Professor Jason Monty, the head of mechanical engineering at the University of Melbourne.

The R150 air purifier from PureAir has been specifically designed for commercial industries and workplaces. Unlike many other household air purifiers on the market, the German manufactured air filtration unit is scientifically proven to reduce active viruses by 99.43% after 45 minutes of device operation. The full study can be read here.

At AES we think why stop at just installing air purifiers in hotel rooms? One thing we know about COVID-19 is the speed and ease of transmission. With a HEPA 14 filtration fitted air purifier the risk of COVID-19 transmission is significantly reduced as the filter is proven to reach a 99.995% sterilisation rate. Being able to provide this level of confidence should be number one on the list for employers welcoming their teams back to the office, or where groups of people is unavoidable like healthcare waiting rooms, gyms, and reception areas.

Where can a Commercial Air Purifier be used?

Our PureAir R150 HEPA-14 filter air purifier can be used in any indoor environment where there could be a risk of airborne contaminants including the COVID-19 virus. Medical grade UV-C light attacks and kills the DNA and RNA of viruses and bacteria passing through the pre-filter and those caught in the HEPA 14 filter.

Protect your customers and employers and provide peace of mind that your business is addressing safety initiatives to keep them safe. PureAir R150 air purifier can be used in;

  • Care homes
  • Gyms
  • Healthcare waiting rooms, including doctors, dentists, physiotherapy and sample collection centres
  • Large reception areas, banks, courtrooms, recruitment agencies, car showrooms
  • Office areas
  • Call centres
  • Childcare facilities and schools
  • Supermarkets

How does HEPA 14 filters work?

HEPA 14, also referred to by H14, stands for High-Efficiency Particulate Air and is the filter class commonly used to filter out bacteria, viruses, and other airborne contaminants.

The efficiency of a filter is how well it can capture and sterilise particles. These particles can be present in all different sizes as each airborne hazard is different. The unit of measurement used for the size of an individual particle is μm or micrometre/micron = 1 millionth of a metre.

Putting particle size into context and to understand why the HEPA 14 is used for more sensitive healthcare high risk transmissible virus areas (and a higher cost) is human hair is typically around 60μm diameter whereas the influenza B virus is estimated to be about 0.12 μm with COVID-19 virus measuring approximately 0.16 μm. These particles are invisible to the human eye and need a higher level of filtration to be removed from the environment.

A regular air purifier will often use a HEPA filter but it does not have the capability of a HEPA 14 filter to trap and sterilise small particles, such as bacteria and viruses effectively. HEPA 14 filters are 10x more effective than HEPA 13 filters and is certified to the stringent international filter EN1822 standards.

As Australia moves into even more uncertain times with snap lockdowns and a reportedly slow vaccination programme uptake, seek to provide those who do want to return to work and move around in the community the confidence that your business has taken proactive steps to keep them safe.

The PureAir R150 is a professional air purifier and sanitiser that changes the air in a room size of 150m3 up to 7 times an hour - quietly capturing 99.995% of airborne particles down to 0.1 micron in size.

Room air cleaners remove particles from the air…but to be effective, they need to have HEPA filter efficiency… most attractively priced room air cleaners are not effective enough.

The airflow through many air cleaners is limited, so the floor area they can serve is usually quite small. To select the right size the airflow capacity of the unit needs to be at least 2 x ACH (Air Changes per Hour) and will have positive effect until 5xACH.

If used in large spaces, air cleaners need to be placed close to people…not in the corner, out of sight.

Increasing the number of air exchanges per hour will reduce the risk of transmission in closed spaces. This may be achieved by natural or mechanical ventilation, depending on the setting.
