Since the mid-19th century good hand hygiene has been recognised as an effective means of controlling the spread of infectious diseases and bacteria. More recent years have seen a growing awareness of the important role hand drying plays in good hand hygiene. This is largely because the transmission of bacteria is more likely to occur from wet skin than dry.
So we know hand drying is important but is there a ‘better’ way to dry them? Warm air hand dryers and cloth towel dispensers are both familiar fixtures in public and workplace bathrooms, but is one better than the other?
Fortunately some bright sparks out there have put in the hard work needed to provide us with some answers.
After undertaking a number of studies, researchers at the University of Westminster have shown that warm air hand dryers actually increase the amount of bacteria on users’ hands, while cloth towels decreases the number of bacteria on users’ hands after use.1
Continuous cloth towel dispensers act to isolate bacteria, with the used section of towel encased in a dispenser, where it remains undisturbed until it is time to remove the towel roll for cleaning. Warm air hand dryers, on the other hand, not only increase bacterial contamination of hands but also spread contamination by blowing bacteria up to a 2-metre radius from the dryer.
Then there’s the environmental aspect: continuous cloth towel doesn’t require electricity so it definitely beats the air hand dryer there. Furthermore, given that cloth towel is cleaned and reused around 100 times, production costs are lower overall, while the fact that they are recycled as wash cloths lessens the environmental impact.2
Clean hands are important and it seems that using cloth towels is a better way of ensuring that cleanliness. I’m not so sure, however, that continuous cloth towels are as useful for drying your hair.
So if you are thinking about this soft, absorbent, hygienic, eco-friendly way of drying hands for your workplace, think no more! We mean, all you need to do is give a call, and Alsco’s friendly representatives will be happy to help you!
