More Effective Modern Hand Dryers

Over the past few years, the importance of good hand hygiene has been at the forefront of people’s approach to controlling the spread of germs in the workplace.  Regular handwashing is important in all workplaces and schools to stop infections.  From preventing the contamination of food during preparation in a restaurant kitchen, through to preventing transmissible illnesses in schools and offices, people are more acutely aware than ever of the need to protect themselves and those around them.

Hand dryers play a key role in good hygiene and are found in most public bathrooms around the country, but some older designs can be less effective at preventing the spread of germs, and in some cases, can even contribute to it.

Can hand dryers spread germs

One of the key ways in which germs can spread from person to person is indirect contact.  If one person has a contaminant on their hand and touches a surface, they can deposit bacteria that will eventually be picked up by the next person to make contact with that surface.  The number of surfaces we touch every day is high. From door handles and desks to taps and tables, we touch hundreds of spaces where bacteria can reside every day.

An often-overlooked surface is the switch for older hand dryers.  Many warm air hand dryers work after the user presses a button to turn the fan and heater on.  This button may be touched hundreds of times each day, and usually by people with moisture on their fingertips that makes it easier for germs to survive.  If people have not washed their hands thoroughly, there can be many different bacteria growing on the button between cleaning cycles and these can be easily transmitted from one person to the next.

Modern automatic hand dryers use a sensor to detect when a user has placed their hands in the drying area, and this automatically switches on the fans.  If a no-touch hand dryer design is combined with antibacterial materials in the outer surfaces of the hand dryer as is the case with the Mitsubishi Electric Wave range, the opportunity for bacteria to spread is limited.

Do Hand Dryers Keep Hands Clean

Older hand dryers used evaporation to dry the skin.  Warm air is blown through a nozzle and the user rubs their hands together in the airflow.  This spreads the moisture over the skin and makes it easier to evaporate.  Unfortunately, it also means that some residue can be left behind on the skin including soaps and bacteria that were suspended in the water.  Additionally, the air that is blown onto the hands is drawn from the atmosphere in the bathroom where it may also have particles of virus or bacteria hanging in it.  While the heating element can help to disinfect the air, it will not remove everything.  This means that not only are potentially infectious particles left on the skin, but more can also be added.

Jet hand dryers such as the Mitsubishi Electric Wave i01 counter this issue in two main ways.  The first is that the drying method is much more effective.  Air is blown at high speed over the skin, and this simply displaces the water, and anything contained in it into a collection reservoir that can be later emptied.  In addition to this, the inclusion of highly effective air filters on the intake that can be easily cleaned means that very little contamination from the surrounding area is blown onto the hands.
