Sterillo Duo + Sterillo Uno

Continuous air hygiene. For safer shared spaces.

An enclosed, separate UVC chamber continuously draws in and treats room air by convection while powered. Duo adds high-speed hand drying; Uno provides the chamber as a standalone unit.

  • Two independent functions
  • Fan-free convection
  • Controlled test evidence

You clean the surfaces.
What about the air?

Washrooms are dynamic. Doors open, toilets flush and people arrive between scheduled cleans. Surface cleaning remains essential, but it does not continuously address what is moving through the room.

Sterillo adds an air-treatment process without adding another unfamiliar appliance or another behaviour for users.

01

Clean routinely

Sterillo complements established surface-cleaning procedures. It does not replace them.

02

Ventilate properly

Room ventilation and air treatment have different jobs and should be specified together.

03

Treat continuously

The separate treatment chamber operates continuously.

01 · Air intake

Room air enters below

The temperature difference created inside the enclosed module establishes convection, drawing room air into the base without a separate fan.

1

Room air enters

Heat from the enclosed lamp creates convection, drawing room air into the separate treatment chamber.

2

Air passes through

The air moves through a chamber containing enclosed UVC technology, without a fan or extra motor.

3

Treated air exits

Air returns through the top vents while the hand dryer remains ready to operate independently.

Sterillo is an additional environmental hygiene measure, not a medical device and not a substitute for cleaning, ventilation or infection-control procedures.

Founder + evidence story · 02:38

It started with a question about odour.

Why add another fragrance when you could investigate what causes the problem? That question led Handy Dryers managing director Stephen Levy from washroom odour to air treatment, and from a separate appliance to technology integrated into a fixture already on the wall.

“The original idea was simple: how do we get rid of smells in washrooms rather than just masking them, but actually get rid of them”

Stephen Levy, Managing Director

One principle.
Different priorities.

Every setting asks something different of its washrooms. Start with the room, its users and the operational goal.

Before you
make the call.

Does Sterillo replace cleaning or ventilation?+

No. It is an additional air-treatment measure. Established cleaning, appropriate ventilation and infection-control procedures remain essential.

What exactly did the independent evaluation test?+

It tested airborne Staphylococcus epidermidis NCTC 11047 in a controlled one-cubic-metre chamber, using three active runs and three unit-off controls.

Can chamber results predict every washroom?+

No. Occupied washrooms differ in volume, ventilation, use, placement and contaminant replenishment. Sterillo is available with different UV-C lamp sizes to suit different washroom sizes and requirements.

Do the dryer and treatment chamber share airflow?+

No. They are separate functions. The treatment chamber operates continuously while powered; the dryer activates when hands are presented.

What maintenance is required?+

Routine maintenance is straightforward and follows many of the same principles as other commercial hand dryers. Periodic cleaning of the unit, checking air inlets and following the manufacturer's recommended maintenance schedule will help ensure reliable performance. The UV-C lamp needs to be replaced once a year.
