have got 2 tips for anyone with this AC or other 2 hose whynter AC, the air filter carbon activated filter, just buy any carbon activated filter, cut to size, and while the AC is on attach it to the outside of the AC, where you see the filter mesh is, and the suction should keep it there!!! 2nd tip, don't buy hose insulator, get a bath towel, wet the towel a lil bit, then drape it over the exhaust hose side and you got an instant hose cooler, enjoy!!!!
