I washed the filter, cleaned it, tried to ventilate it in the pantry. Did not help. Sent it in for service under warranty. After 2 weeks, they called, they said that there was no smell of burning. Explained everything to them. They called after another 2 weeks, they say they say there is a smell, but it looks like a flavor. In an air purifier? Seriously? 3 months was not, and then bloomed . Kitfort support is a separate branch of hell. If you want to remotely fray your nerves - write to them. Before that, I bought a lot of small equipment in kitfort, everything worked ok. The purifier is a failed purchase. Don't listen to purchased reviews. In the future, I will not take anything from Kitfort and I do not advise you.
