The water tank size varies by model - the N-200 holds 5 Litres, and the N-300 holds 8 Litres

The operational hours of Leitz TruSens Humidifiers depend on the unit and its settings. The N-200 Humidifier lasts 50 hrs. on Speed 1, 25 hours on Speed 2, and 16.6 hours on Speed 3.  The N-300 Humidifier lasts 80 hrs. on Speed 1, 40 hours on Speed 2, and 26.6 hours on Speed 3.  

Leitz TruSens Humidifiers feature a top-fill water tank. This means that water can be added without the need for removing the tank from the base of the humidifier, it can be filled by pouring water using a water pitcher / jug.  

When the water level is low, the unit will shut off and the tank indicator will turn red, this means the humidifier needs to refilled. Remove the water tank lid and use a pitcher/jug to fill with clean, cool water. Do NOT pour water directly into the mist outlet or the base/reservoir.

The aromatherapy tray is featured in both N-200 and N-300 and allows the user to add essential oils to the pad which is diffused into the room through the mist. using the aromatherapy is optional and will not affect the performance or function of the humidifier. 

Essential or scented oil should NOT be added directly to the water in the water tank. This may damage the unit. Essential or scented oils can be added to the aromatherapy tray on the back of the unit to help diffuse the scent around the room during operation. Note: only use 100% natural essential oils.

If you observe mineral scale buildup, try replacing the water softening filter. If the problem persists, you may have especially hard water in your area, and may want to use distilled water in your humidifier.

Leitz TruSens Humidifiers should be cleaned and descaled every week. Please refer to the maintenance and cleaning section in the owner's manual to learn more. The Humidifiers should not develop mould if properly used and cleaned. If water is left standing in the humidifier for an extended amount of time, mould may begin to develop. 

White dust in the mist is a result of misting hard water. Our water softening filter featured in all Leitz TruSens Humidifiers reduces the hardness of water being used which will reduce the amount of white dust in the mist.

All the Leitz TruSens Humidifiers come with a water softening filter included. Replacement filters are sold separately.  

The humidifiers feature a replacement indicator that will notify you when it is time to replace the water softening filter.  Plan on replacing the water filter every 3 to 4 months, with normal use of 8 hours per day and average water hardness.

Please note that if you are storing the humidifier in the off season, we recommend replacing the filter each new winter/dry seasons.

In order to change the filter in your Leitz TruSens Humidifier, unplug the machine and empty the tank. Next, the old filter will need to be removed for the replacement filter to be added. For optimal performance, remember to soak the new filter in a bowl of water for 1 hour before installing. Also, remember to tightly secure the grey cap with filter onto the water tank until the cap's indicator meets the lock symbol on the tank. Once the new filter is secured in the humidifier, hold the Filter Reset Button until the red indicator turns off. 

After replacing the filter on your humidifier, simply hold the Filter Reset Button until the red indicator turns off.  

If you replace the filter before the filter replacement indicator turns red, you can hold the Filter Reset Button for 10 seconds (until you hear a chime), to proactively reset the filter indicator.

Leitz TruSens ultrasonic Humidifier uses a magnet to vibrate a ceramic plate at frequencies higher than the range of human hearing. This very fast vibration causes water droplets so small that they can stay suspended in the air. This is the mist that is seen exiting the chimney.  

Leitz TruSens Humidifiers allow users to press the – or + button to set their own target humidity. Reaching optimal humidity in a space is very dependent on the initial humidity and temperature, size, and shape of the room as well as the amount, location, and absorption of any walls, obstructions, and furniture. The speed settings of the humidifier relate to the volume of mist for each setting, i.e., Speed 1 is 100 ml/hr, Speed 2 is 200 ml/hr, and Speed 3 is 300 ml/hr. 

The separate SensorPod™ is both a remote humidity monitor and control. The remote-control feature allows users to control the humidifier’s power (on/off), misting speed, and dimmer (on/off). Placed up to 10m away from the humidifier, SensorPod™ detects moisture levels in the air and sends real-time readings for the humidifier to automatically adjust. 

Both the N-200 and N-300 can be used without the SensorPod™ but will only operate in Manual Mode and not display a humidity reading if the SensorPod™ is not connected.  If you'd like to run the humidifier in Auto Mode, you will need to use the SensorPod™.​​

If the humidifier shows a flashing antenna symbol or is displaying "- -" on startup, please allow up to 60 seconds for the SensorPod™ to connect. If you notice this after 60 seconds after startup or during operation, first check that the SensorPod™ is within range of the humidifier and check the batteries. In the rare event that the SensorPod™ needs to be re-paired to the humidifier. Refer to the manual for re-pairing instructions. Press and hold the power button on the humidifier for 3 seconds, once the humidifier beeps, press and hold the power button on the SensorPod™ for 3 seconds until the humidifier beeps again indicating that the SensorPod™ is connected.

The UV-C light does not require replacement during the life of the product. 

Both humidifiers offer a cool mist feature to keep your air hydrated benefiting skin, nasal passages, throat, and lips. The N-300 additionally offers a comforting warm mist setting max temperature of 28°C, allow 30 minutes or more for the mist to reach the warmer temperature.
