It has no direction on how to clean it, and it appears to have a little fabric filter in the top. I wish that Wayfair's chat feature was more than just a computer generated app that cannot answer questions. Pretty frustrating. I don't know if you can get the filter wet, if it needs to be periodically replaced, and if so, where would you get that replacement. Or does getting the lid wet while trying to wash it compromise the air-releasing mechanism?
