This allowed me to carefully bend my air conditioner without an air duct. My ductless air conditioner is also a great product but it hangs high on the wall so it doesn't have much room to dust the top which is very important. Also, my Mediify air filtration device has removable filters that are cleaned monthly. The soft, flexible cloth is gentle enough to allow the filter to be vacuumed first and then rinsed. Really made this monthly task easier. The same goes for the removable filters on my air conditioner. I kept the holder that came in the box, wrapped it in wide clear tape and now I have a permanent holder to protect the brushes.
