The HEPA filter can easily be fitted into existing hand dryers. Besides eliminating about 99% of bacteria and other harmful particles, the filter also lengthens the life cycle of the hand dryer.
The holder with filter is installed in front of the air inlet by means of two screws.
You should replace the HEPA filter 2-4 times a year depending on usage and the sorrounding environment. The filter is easy to replace and ensures that the air is cleaned efficiently.
