re: #325 Feline Fearless Leader
Windows were open the other day - which could have been a factor. Getting the A/C filter changed is a building maintenance task, and something I can bring up with them.
Will also look into doing something for better circulation within the apartment. Only one fan doing that right now (when the A/C system is not kicked on and helping). Would love a ceiling fan in here, but getting one installed is a major pain in the ass paperwork-wise with the apartment management.
Also, have you tried a dehumidifier?
