Used Takagi water purifier replacement cartridges. According to newsletters and websites, they can be reused as deodorizers. Examples: - Deodorizing trash cans - Deodorizing refrigerators - Deodorizing shoes - Deodorizing used diaper bins Every time I replace the water purifier cartridge, I dry it instead of throwing it away and reuse it for deodorizing purposes. I have accumulated quite a few, so I'm offering them to anyone who needs them. They are used! They are not new!! They have been dried and stored at home. They will be shipped in simple packaging. Please research the methods of reuse yourself and use them at your own risk. I am not responsible for any issues. Please consider this only if you understand the above.
