Unit has been running for years 24 hours a day, 365 days a year, without refrigerant replacement (would only be possible with appropriate know-how anyway). Regular cleaning of the filter before the air intake is important.

Hoi - we bought the Kibernetik a long time ago (I think it's been 5 years now) and have never had to replace the dehumidifier, it still dehumidifies like on the first day. I don't think it is intended to replace the agent in this part, but I could be wrong. LG
