This rating is based on the watts per dry of the hand dryer which is derived from the rated power and the time taken to dry the hands. We have used the figures based on either the manufacturer’s dry time, if yet to be in house tested or based on the in house testing dry time we have conducted. This will also be based on the most energy efficient setting, if the hand dryer is adjustable for speed and/or heat.

These ratings are based on the in house testing we have conducted regarding dry times. They show realistic comparisons of what to expect from each hand dryer. Please note that the manufacturer stated dry time is not always accurate when compared to the hand dryer being used in realistic conditions. The ratings are based on the hand dryer being placed at its high speed setting if it can be manually adjusted.

This rating is based on the manufacturers stated sound level, usually at 1m. Please see the section titled “how quiet is the” for more information and independent test results, which give a more accurate noise decibel level. 

These ratings will also be based on the low noise setting, if the hand dryer is adjustable for speed. Therefore at full speed the hand dryer may not be quiet, however it may be adjustable to become quiet if this is required.

Hand dryers are a hygienic method of drying the hands. The better the dry, the less the risk of carrying germs on wet hands. Some however, have gone that little bit further to enhance the hygienic aspects of the hand dryer. These ratings are based on these extra factors that have been added to aid the hygienic properties. These ratings are based on an added together scoring system where the higher the rating the more enhanced the hygienic properties of the hand dryer. Cold Plasma Clean (CPC) is the most advanced hygienic property on the market and scores a maximum of 5 stars.

This rating is based on the number of motor life cycles (number of uses) the hand dryer, in theory, will last for. This is based on the motor life expectancy given to us in hours, from the manufacturer. 

The number of cycles (uses) has been calculated as follows:
(Number of seconds in the hour / seconds per dry) x motor life hours 

For a more individualised longevity calculation based on your own usage numbers please use the life expectancy calculator on each product page.

Some hand dryers would not be suitable for some locations where abuse may be likely such as a train station or night club. However the same hand dryer would be suitable for an office or school location. These ratings are based on an added together scoring system where the higher the rating, the more suitable we would recommend for areas where abuse may be likely.
