ページを印刷するThe unit itself emits an unpleasant odour:
A new air purifier still has a slight odour of its own (fresh plastic, new motor, new paint, etc.). This new smell
dissipates within a very short time (1-2 weeks) !
The air sensor is causing problems:
Please read the notes under point 5 (Note on air sensor operation / Auto mode). If the explanations given there are
not applicable and the air sensor continues to cause difficulties (despite cleaning), read the following notes:
1. Have you given the air purifier a "free hand" for 12 hours in "auto mode" 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 ensure that the air sensor function is not used when the air purifier is in a draught (e.g. between two
open windows and/or doors).
3. High room humidity can also cause the air sensor to detect poor air quality.
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, you should refrain from using the automatic air sensor operation (Auto
mode).
It takes too long to neutralise smoke and/or odours:
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 many odour particles are flowing in and how the air circulation is at
your place !
This is because the inserted odour filters always absorb/remove only a part of all odour particles in one pass.
Therefore, a general rule is three filter passes 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 HEPA fine filter = 99% effectiveness. For odours, the active carbon 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 also important to consider that odour patterns can already be present in the furnishings - and
depending on the nature of the individual materials, it can take a considerable amount of time until these have
released the odours again.
(The WDH-220B air purifier only eliminates odours that are circulated or filtered through it).
The unit does not respond / The unit cannot be switched on:
1. Check that all filters are properly inserted and that the front filter panel is properly closed.
2. Check whether the filter change indicator lights up. If so, change/clean the filters and then press the rest button
(see point 7. of the instruction manual).
