Good hand hygiene has long been important in the fight against germs and bacteria. COVID-19 has made effective hand washing even more of a necessity as we fight to prevent the spread of the virus.

This article discusses how robust hand hygiene can be supported in schools with the help of Dyson’s ™Airblades and their all-important HEPA filter.

It also looks at how Dyson’s HEPA filter works and why a HEPA filter is such an important component in hand dryers.

Why is hand hygiene so important?

Leaving a school washroom with wet hands is a sure-fire way to spread germs. In fact, damp hands can transmit up to 1,000 times more bacteria than dry hands. This means that no matter how thoroughly you wash your hands, you need to pay close attention to how you dry them too!

What is a HEPA filter and what does it do?

A High Efficiency Particulate Air (or HEPA) filter is a special type of high-quality air filter that removes and traps around 99.95% of particles (such as pollutants, pollen, dust, allergens and bacteria) from the air.

The filter is made of a collection of thousands of randomly-aligned fine fibres. You can find HEPA filters in a range of appliances, such as air purifiers and vacuum cleaners. Their use has health benefits for a range of individuals, such as pet owners and asthma sufferers, for example.

But, what does this have to do with hand hygiene, you might ask? Well, when drying your hands with a hand dryer, the last thing you want to do is dry them using dirty, bacteria-filled air! With a hand dryer containing a HEPA filter, you can be sure that the air blowing onto your hands is squeaky clean.

What key benefits does the Dyson Airblade offer?
