You should use a cooler with rotating fans to move air around so that there is no area that gets to damp. When you continuously get evaporation collected on walls, surfaces, or furniture, that’s where mold and mildew will happen. So If you are using a portable evaporative cooler you should keep in mind that the air should not be collected on walls or surfaces which will create the place damp. You should keep the fan rotating to avoid such conditions. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerCancel replyYou must login or register to add a new answer.
