The unit itself emits an unpleasant odour:

The operating mode "ozone" and also the UV lamps produce a certain odour. This odour is typical of their function

and generally arises during their operation.

The operating mode "anions" is not smellable for most people. However, sensitive people perceive a certain

"smell". This is because the anions slightly electrostatically charge the air (similar to after a thunderstorm).

after all, a new air cleaner still has a slight odour of its own (fresh plastic, new engine, new paint etc.)... but this new

smell fades within a short period of time (1-2 weeks) !!!

The air sensor causes problems

Please read the instructions under point 7 (activating the automatic air sensor) and in case of 9 x active light bars

(poor air quality) the instructions * listed below. If the explanations given there do not apply and the air sensor

clearly indicates a wrong tendency, please check that the small openings at the front left of the air sensor are not

dirty. If necessary, blow hard into the air sensor; this should solve the problem.

The air sensor remains permanently on 9 x active light bars (poor air quality).

1. Have you ever given the air purifier "free rein" in the automatic air sensor function (Auto) for 12 hours or have

you let it run continuously ? Especially at the beginning and especially with smokers, 12 hours of continuous

operation and more are quite normal, because often particles/odour patterns sit in the entire inventory

(curtains, upholstery, carpet, etc.) and depending on the nature of the material, it can take a considerable time

until this inventory releases the odours again.

2. Please make sure that the air sensor function (Auto) is not used when the air purifier is in a draught (e.g.

between two open windows and/or doors).

3. From a humidity of approx. 80% r.l. upwards, the air sensor probe may malfunction. In this case, please disable

the air sensor function (Auto).

4. In very rare cases, the air sensor may react negatively to certain substances (e.g. furniture polish, perfume,

etc.) in your room. In these cases, we ask you to dispense with this special operating mode (automatic air

sensor function).

It takes too long for smoke and/or odours to be neutralised

In general, our air purifier is very well suited for odour and smoke neutralisation. But please note that the result/end

result of our air purifier always depends on how much odour particles are flowing in and how the air circulation is at

your place !

This is because the inserted odour filter always absorbs/removes only a part of all odour particles in one pass.

Therefore, a general rule is three filter cycles until all odour particles have been absorbed.

(Note: When filtering dust and particles, one filter pass is sufficient to clean the air, as all particles are retained in

the fine filter = 99% effectiveness. For odours, the carbon & catalyst filter is mainly used and here the filter medium

needs approx. three filter cycles per sqm³ of air until one can speak of clean air = 33% effectiveness !!!).

Furthermore, it is important to consider that odour patterns may already be present in the inventory (furniture) - and

depending on the nature of the individual materials, it may take a considerable amount of time until they have

released the odours again.

(Apart from the "ozone" function, our air purifier almost only eliminates odours that are circulated or filtered through

it. )
