My cousin ruined my air purifier

My cousin ruined my air purifier. I offered to babysit my cousin, who is twenty-seven years younger than me, because I thought that I could handle her. I was definitely wrong though. She is the worst behaved child that I have ever seen. She bit me so many times. She dumped her juice all down my HVAC vent, and she peed on my air purifier. I just don’t understand what is wrong with her. I didn’t go with her when she said that she had to use the restroom because she is five years old, and her mom told me that she is potty trained. Well, a few hours later, I smelled something gross, and I found that it was coming from my air purifier. It took me awhile, but I finally realized that she had peed on my air purifier. I was furious. She did apologize because her mom made her, but she didn’t seem to mean it. Now, my air purifier stinks, and I can’t seem to get the smell out. I have cleaned the air purifier a dozen times, and it still stinks. Normally, my air purifier would help get some of the stinky smells out of the house, but now that it is the source of the smell, I don’t know what to do. It is getting cold outside, so I can’t leave the windows open just to use my air purifier. I am afraid that I am going to have to stop using my air purifier altogether. That makes me really sad to think about. I love my air purifier so much, and I really don’t want to have to stop using it altogether.
