Levoit 200S filter support

Hi, I use a Levoit 200S next to the printer to help keep the air clean. The Levoit spare filter comes in a set of 2, so I made a custom support to store the spare behind the air purifier. This is 4 support to install a spare filter behind the Levoit 200S air purifier. The rectangular block is optional and is used to have the bottom hook at the same height. Once the bottom hook is installed, place the filter on the hook and use the air filter to place the side hook at the right distance. For best results, leave a bit of room on the side hook to have an easier time sliding the filter in. Use 2-sided tape to install the hook. Because the corner of the Levoit 200S is rounded, it is normal that ⅓ of the side hooks doesn't stick to the surface.
