This is a FRESH DIY! After searching online for a diaper pail deodorizer that actually works, I ordered some carbon filter sachets that had great reviews. The sachets are loose filters and do not come with a holder. I now needed a filter holder to secure the filters to a trash lid. I didn’t want to spend money on something that I would have to modify to work with my new filters. I also couldn’t let myself buy something I felt like I could make. Here is how I modeled and then printed a DIY Carbon Filter Holder for our trash can (diaper pail).
I initially modeled my DIY carbon filter holder as one solid piece to work out the geometries. Once I was happy with the design, I cut the model into a top and bottom that would easily print. I designed tabs and slots that allow the top and bottom to fit snugly together. The first design had a solid top. After starting a test print, I realized it would take a long time to print, so I added cut-outs to decrease the print time and amount of filament used. I left a solid area in the middle large enough for a command strip.
The fit of the two halves was snug after printing. I added super glue to the edges to be sure the motion of the trash lid won’t cause the holder to open. I used a command strip to attach my new DIY carbon filter holder to the underside of the trash lid.
After being installed for the day, it was clear my DIY carbon filter holder with activated charcoal filter sachets had freshened up our smelly pail! I’m planning on an updated design that will have an area to attach a cotton swab with essential oils for a scented filter. Check back for the update!
