New model of hand dryer might reduce the risk of infection
Hand washing is crucial to help of reducing the spread of bacteria and viruses. Drying hands properly is an important step as damp hands can spread up to 1,000 times more bacteria than dry hands (Note 1). Most of traditional hand dryers are warm air drying without effective filters installed inside. It might have a risk of sucking up bacteria from the air and land on the newly washed hands (Note 2).
Dyson launched Airblade™ hand dryer product solutions, a sensor-operated touch-free hand dryer, with HEPA filtration allowing purification of the air used to dry hands. The HEPA filter captures 99.95% of particles up to 0.1 microns (Note 3). The filter can also capture bacteria and viruses (Note 4). Hands are dried with HEPA-filtered air, not dirty air, also independently proven safe (Note 5).
New semester is going to begin. Parents are concerning about proper hygiene in school during outbreak of COVID-19 pandemic. For now, some schools have installed Dyson Airblade™ hand dryer to protect the student away from the risk of infection in school environment.

Which kind of test is more appropriate to evaluate purifier performance?
【 Which kind of test is more appropriate to evaluate purifier performance? 】
CADR test stands for Clean Air Delivery Rate and it is the metric generated by old test methods dating back to the 1980s. Conducted in a compact chamber measuring just 28.5m³, air quality is measured with only 1 sensor. Unlike real homes, the CADR test is conducted for 20 minutes in a small chamber, tracking just the speed of filtration, rather than the quality. Therefore, it may be not a standalone metric to assess the full performance of modern day intelligent purifier in modern homes.
The POLAR test chamber is much bigger than a CADR chambler, and more representative of real-world environments than existing standards dictate with a 81m³ footprint and no external fan to support air circulation. It is positioned in the corner of the room, rather than the centre, reflecting a more likely position in the home. Around the chamber there are 9 sensors – 2 per corner at different heights and 1 in the centre – to assess the evenness of purification throughout the room.
Dyson air purifier fans are engineered to work in real living spaces. Therefore, Dyson engineers developed POLAR test. Based on a larger room size of 81m³, 9 different sensors continually collect air quality data throughout the entire room. Ensure purified air is evenly distributed in whole room*.

Dyson Airblade™ 9KJ - Case Study
Dyson is a must have brand in your factory, office or washroom renovation project!
SD Electronic Materials (Hong Kong) Co., Ltd. installed a total of 10 Dyson Airblade™ 9KJ hand dryers in their washroom renovation project. Some installations are different, they installed inside the mirror cabinet in front of the wash basin instead of install on the wall next to the wash basin. After washing hands, employees can reach forward to dry their hands directly. It can reduce water drop on the ground and keep the ground dry. Of course, the installation plan depends on the space. If the space is limited, you can choose Dyson Airblade™ Wash+Dry.
In addition, SD replaced Dyson Purifier Hot+Cool Formaldehyde in their office, features monitoring air quality any time and purify air.
It heats in winter, cools you in summer, and the oscillates up to 350 ̊. In summer, using it with air conditioner helps to deliver cold air around the whole room, which can help electricity saving.
Every renovation is for longer-term saving!

The new Italian restaurant Venédia in Central has installed Dyson Airblade V in their toilets. Dyson Airblade V has a slim body which is designed for compact spaces.
Another reference from the Bakehouse factory. They chose Dyson Airblade wash+dry(Photo 5) and installed them at the entrance to ensure that all employees wash their hands before entering the factory. Dyson Airblade wash+dry is designed to wash and dry your hands at the sink to avoid water dripping on the floor.
