Choosing the best hand dryer

Hand washing plays an essential role in maintaining the health and safety of the people in your building.  From preventing the spread of illnesses such as flu and Covid through to maintaining the correct hygiene standards in food production, all staff should wash their hands properly and dry them afterwards.

Most bathrooms now use electric hand dryers for this purpose.  They are more cost effective and have much lower environmental impact than paper towels.  They do not create land fill and are reliable in use.  

There are two main types of hand dryer – warm air hand dryers which use slow moving warm air to evaporate water from the hands and leave them dry, and modern, jet hand dryers which use a faster moving jet of air to blow the droplets of water straight off the surface of the skin 

When it comes to choosing the best hand dryer, there are a few things to think about:

Hygienic hand dryers

With a conventional warm air hand dryer, the main barrier to good hygiene is that the dryer can leave a residue on the skin.  If the hands are not fully clean or rinsed, anything that was contained in the water left after washing will remain on the skin after drying.  This can include bacteria and virus particles as well as any cleaning products.

With a jet hand dryer such as the Mitsubishi Wave i01, all the water, along with anything it is carrying is blown off the surface of the skin leaving them cleaner.

If a hand dryer uses a push button operation rather than working automatically, it provides a path for one person to spread germs to others.  Hands free hand dryers avoid this point of contact and help to stop the spread of illness.


Noisy hand dryers can be distracting in the surrounding area, and some people may avoid using them.  Conventional slow air dryers have a wide nozzle and exposed fan which means that they make a great deal of noise in use.  On average, a warm air hand dryer will be as noisy as 87dB – the equivalent of heavy traffic.  By comparison, the internal aerodynamics of a jet hand dryer makes them much quieter in use – as little as 57dB – or the equivalent of a normal conversation.  This makes people much more comfortable using quiet hand dryers and helps to prevent sound escaping into surrounding areas and disturbing people nearby.


On average, a conventional hand dryer will take between 30 and 60 seconds to fully dry the user’s hands.  It takes time for the heating element to get up to temperature, and until it does, the dryer is ineffective.  Once the air is warm enough for use, the user still needs to hold their hands in the airflow and rub them together for long enough to allow the moisture to evaporate.

By comparison, a jet hand dryer, which does not need to have a heater for the air to work effectively is ready to go immediately.  This, coupled with the fact that water is simply blown from the skin means a much faster drying time – as little as 9 seconds.

A faster hand dryer means that people are more likely to use it correctly which in turn can contribute to better health and safety.
