HEPA Filter Technology
HEPA filters, short for High-Efficiency Particulate Air filter, were initially designed to trap fine radioactive particles. They are capable of filtering 99.95% of particles at 0.3 microns and 95% of particles at 0.1 microns. To put this in perspective, 1 micron is just 1/10,000 of a centimeter, while the smallest particle visible to the naked eye is 40 microns. A particle measuring 0.3 microns is significantly smaller than dust mites, mold spores, pet allergens, and pollens. HEPA filters find wide application in medical settings such as cleanrooms, pharmaceutical manufacturing, and any environment requiring clean or sterile conditions.
Why is HEPA technology so important in a hand dryer?
If HEPA filters were initially designed to remove fine radioactive particles, then why are they so important in bathroom hand dryers? In a world where hygiene takes precedence, public spaces have been under vast scrutiny. The most highlighted of which, are of course common use bathrooms. Arguably attracting the most traffic per square meter, measures must be taken to reduce their affect on consumers. Yes, regular cleaning is recommended however in peak times it is not practical. Common hand dryers that do not contain a HEPA Filter draw in air from the surrounding environment and pressurise it onto your clean hands. Our Drysonic hand dryers are designed to minimise the surrounding environments impact, keeping your hands as clean as they were before drying.
How often does my HEPA filter require service?
In order to ensure the HEPA filter is doing the job it was designed for, we at Drysonic recommend to clean or change over your products filter every 3 months depending on your user traffic.
