Hand dryer hygiene: debunking the myths and setting the record straight
Hand dryers are a staple in public and workplace washrooms, offering an eco-friendly and cost-effective way to dry hands. Yet, they’ve also been the subject of persistent myths particularly around hygiene. Are hot air hand dryers hygienic? Do they spread more germs than they eliminate? And how do hand air dryers compare to other methods of drying, such as paper towels?
At phs Warner Howard, as experts in supporting your washroom hygiene, we love nothing better than busting myths and setting the record straight! In this blog, we’ll separate fact from fiction and explore why air hand dryers in public restrooms are not only safe but often preferable. Whether you manage a busy office, school, restaurant or healthcare facility, here’s what you need to know.
Are hot air hand dryers hygienic?
Let’s tackle the big question head-on: Are hot air hand dryers hygienic? The answer is yes, when used correctly – they are highly hygienic and pose no more risk than any other hand-drying method.
Many concerns stem from outdated studies or exaggerated headlines. Modern air hand dryers for bathrooms are equipped with HEPA filters, high-speed airflow, and antimicrobial surfaces, making them just as sanitary (if not more so) than shared paper towel dispensers.
In fact, research has shown that effective handwashing is the most important factor in removing bacteria, not the method of drying afterwards.
Myth 1: hand dryers spread germs everywhere
One of the most persistent myths is that air hand dryers blow bacteria all over the room. While it’s true that air movement can circulate particles, studies show this is no more significant than the air displacement caused by walking around a washroom or flushing a toilet.
Modern dryers with HEPA filters actually reduce this risk, removing up to 99.9% of bacteria from the air used during drying. Many dryers also have angled airflow or enclosed drying zones to minimise spread even further.
So next time someone asks, “Are air hand dryers safe?”, the answer is a confident yes – especially when backed by proper handwashing.
Myth 2: paper towels are always better
Paper towels are a popular alternative, particularly in healthcare environments. But while they may offer quick drying, they also present hygiene risks when not properly managed, such as:
● overflowing bins
● used towels on the floor
● touchpoints that can harbour bacteria.
Plus, paper towels generate significant waste and require constant restocking, which can increase operational costs and carbon footprint.
Hand air dryers, on the other hand, offer consistent performance without needing bins or frequent intervention, making them ideal for busy washrooms.
Myth 3: hand dryers are too noisy
Older models were indeed loud, which made them problematic in schools, libraries, or offices. But the new generation of air hand dryers for bathrooms includes ultra-quiet options designed to operate at reduced decibels.
These quiet units are perfect for noise-sensitive environments, and many models allow you to adjust airflow and noise output without compromising drying speed.
The benefits of using air hand dryers
Now that we’ve dispelled the myths, let’s look at why so many businesses are switching to hand air dryers:
Hygiene:
● touch-free operation reduces cross-contamination
● HEPA filters clean the air before it reaches your hands
● antibacterial surfaces improve cleanliness.
Sustainability:
● no single-use waste
● reduced carbon footprint over time
● ideal for organisations with sustainability goals.
Cost-effectiveness:
● lower operating costs than restocking paper towels
● less waste means fewer collections and disposal fees
● long-lasting and low maintenance.
User experience:
● fast drying times (often under 10 seconds)
● sleek, modern designs to complement any washroom
● quiet and accessible options available.
Whether you manage a school, office or public venue, air hand dryers in public restrooms offer a reliable, hygienic solution that benefits everyone.
