Can I extent my Vorrezensenten only endorse and recommend the weekly / monthly (depending on the operating time and degree of soiling) extraction with a vacuum cleaner.
(Of course, this device should then also have a built-in HEPA filters)
The device receives the indoor air of a 20m² large room in a maximum of one hour, noticeably clean and is on the first level still, more or less easily also be used at night. I myself have a very peaceful night's sleep and was able to sleep a couple of times even at Stage 3, noise sensitive people would thereby probably safe zubekommen not sleep, but I can only speak for myself.
Easy to clean with a vacuum cleaner, kidnerleichter filter change and service life of already mentioned, large HEPA drum of one year, make this device for me at a great air filter, which is his job full justice and the maintenance costs at a fairly low price with relatively low monthly ,
Solely the relatively high power consumption of approximately 90 watts at level 3 sit a downer.
See. Luftreinger / humidifier with water dish, eg Venta. The my opinion, but by permanent chemical additive (Wasserhaltbarmachung) and the lack of HEPA filters in any case (already purely physically) draw the short straw.
Am very satisfied and recommend further the unit with a clear conscience!
