Hi, Humid! Thank you for sharing your feedback with us. Sounds like you are on the right track with cleaning the filter. Which is recommended to do so every two weeks, based on normal operating conditions. We do not recommend taking the dehumidifier a part to clean the coils, for safety reasons. To ensure the cabinet and coils are clean, it is recommended to dust the cabinet with an oil-free cloth, or using a damp cloth. You can also vacuum the grill using a brush attachment. You are able to locate any cleaning instructions in the manual, with the following link, ftp://ftp.electrolux-na.com/ProdInfo_PDF/Edison/2020266a0493en.pdf on page 8. Kindly, Ciara
