  The effectiveness of this technology regarding the inhibition of viruses and bacteria has been tested in independent laboratories. In addition, case studies have been carried out in hospitals, educational establishments and vet clinics, among others.

• Easy to use and economical to maintain
  The maintenance required for nuvohla is the replacement of the cartridge when it runs out. The lifetime of the cartridge varies depending on the heat/humidity conditions of the environment. The electrical power consumption of the device is low. nuvohla does not require filters or UV lamps.

• Contamination level detection
  Depending on the indoor air quality, a LED-light will show different colours: blue, green, orange and red.

• Error detection system
  In case the cartridge is incorrectly inserted or is not inside the device, a flashing and two fix red-light signal will be activated.

• Cartridge replacement alarm signal
  One week before the cartridge runs out, the replacement indicator will be activated and can be replaced. When 3 months have elapsed since cartridge installation, the red-light indicator will be activated and the device will automatically stop.

• Additional features
  – Wall and surfaces mounting pack available
  – Wide coverage: the area of effect of the nuvohla purifying device is 30-50 m2 depending on the contamination and environmental conditions

Technology

Hydroxyl radicals are generated from sunlight and are called “nature’s detergent”.
These natural substances are easily extinguished in the environment with other contaminants after inactivation.
How does hydroxyl radical work?

Step 1: Hydroxyl radicals surround the protective coating of bacteria and viruses.

Step 2: Hydroxyl radicals react with hydrogen from bacteria or virus protective coating.

Step 3: Converts pollutants into H2O.

When the device is connected to the power supply and the power button is pressed, the “warm up time” of the air quality sensor is activated for 3 minutes. The ON/OFF LED indicator lights blue and the front RGB LED changes its intensity in blue (or remains off depending on configuration 1-2-3). If during the warm up time the night mode is activated, the front RGB LED turns off and the fan speed is reduced.
After this time, the RGB light signal will stop the latency (except in night mode which remains off) and will work as explained in each configuration.
Night mode:
Night mode light signal turns GREEN. All other lights are turned off.
Operates at lower speed and reduces the sound level.
Cartridge change:
The cartridge change light signal is RED. It lights up one week before it runs out. The RGB light signal operates normally depending on each configuration.

Replacements and spare parts

Nuvohla purifier works thanks to the cartridge inserted in the unit. It must be inserted into the space indicated by lifting the non-adhesive end of the label and leaving this side facing outwards for easy removal. After three months of operation with the same cartridge, the device emits a light signal indicating that the cartridge is empty and must be replaced’.
How to remove the cartridge?
The nuvohla room/lift device has two accesses to the cartridge:
– Rear access: a small access door that opens outwards by pressing the upper tab.

The cartridge is removed by grasping the label with your fingers and pulling it out of the device.
¹Even if the tank contains some liquid, replace the cartridge anyway, otherwise your purification device will not perform its functions.
– Front access: at the base of the device there are two Phillips screws that need to be unscrewed so that the front cover of the device can be removed by pulling it off from the bottom. An access door like the one on the back of the device is then visible. The process of changing the cartridge is the same.

To insert the cartridge and close the device, follow the process in reverse.
How to clean the pre-filter?
The nuvohla purification device has a foam pre-filter which protects the fan and the other inside components from dust or insects. This pre-filter must be cleaned every time the cartridge is changed, or once a month if you are in a dusty environment. To access the pre-filter, open the side door of the device by pressing its lateral flap and opening it to the left. The pre-filter can then be removed. The pre-filter is cleaned by shaking it slightly and then rinsing it with clean water. Let it dry completely before inserting it back into the device.
