Air purifiers are designed to remove impurities from the air and capture them mechanically within its filter. Sterilisers, like those found in the Sayoli range, actively eliminate pathogens from the air without removing any matter.

In purifiers, a much important feature is their throughput, that is the amount of air pushed out of the device. In sterilisers, the process is much more sophisticated and the dependence between efficiency and effectiveness is not linear.

Yes, Sayoli is meant to be operated at all times when space is being used. Whether it is in the bedroom, office or factory floor, Sayoli is meant to be on during all working hours to ensure the air is constantly sterilised for the most effective operation. 

Sayoli 30 - 12m2 per hour 
Sayoli 60 - 25m2 per hour 
Sayoli 150 - 60m2 per hour 
Sayoli 200 - 80m2 per hour 
Sayoli 300 - 55w - 115m2 per hour 
Sayoli 300 - 110w- 115m2 per 45 minutes 
Sayoli 300 - 165w- 115m2 per 30 minutes 

Sayoli 30 and Sayoli 60 are powered using a USB C power port and require 5V (3amp) - these units can be powered in your car and also using USB power banks.

Sayoli 150, 200 and the rest of the professional range require a constant mains power connection.

None of our units have built in batteries.

All units operate within 250-280nm UV-C.

The UV-C bulbs in the Sayoli 30 and Sayoli 60 are replaceable and have an average life of 6,000 hours.

For the user's safety, replacement of the radiator is possible only at our service centre.

Sayoli sterilisers use special UV-C radiators covered with a protective layer to prevent ozone production during operation. In the event of damage to the bulb, a special protection prevents the device from being switched on.

The cost of replacing the bulb is £85 for Sayoli 30 and £120 for Sayoli 60. The prices include the costs of re-delivery to the customer.

Unfortunately not, current units do not have a movement sensor or timer. They need to be manually switched on and off everyday.

The steriliser design might seem very simple at the first glance, however, the science behind it is much more sophisticated. The dependence between the exposure time and the radiator power is the most crucial aspect of an effective steriliser. Energy-efficient radiators would require more time for sterilisation; therefore, their efficiency would be lower. However, it is necessary for a correct process.

Ultraviolet radiation is only harmful in direct exposure. In flow sterilisers, this problem has been solved by means of special disinfection chambers that eliminate the risk of burns.

100%. Our devices can be used in homes, nurseries, hospitals, dental clinics, offices and more. Our design ensures they do not emit any ozone.

The simple answer is yes. Our UV-C radiators kills 99.9% of airborne viruses and bacteria.

Our usual lead time is 15 working days from order. In very busy period this may extend by an extra 5 working days.

All our products are made in our state of the art facilities in North Central Poland.

If the unit detects the lamp is damaged due to being knocked over the device will not turn on.
