I don’t know what to do about my air purifier

My air purifier is making pretty odd noises.

My air purifier never made those noises until this moment in time, so it sort of concerns me.

I am thinking that my air purifier may not last much longer… The noises are getting worse by the day. My air cleaner is upstairs, so I only hear the noise when I get upstairs, but I can also tell that the air cleaner is getting worse and worse each time I head upstairs and hear it. I am really sad because I easily want to have an air purifier during these terrible times, but I am also certain that I will not be able to afford another air cleaner. I just don’t have extra currency right now, and I think that I should not get another air cleaner with the little extra currency that I do have. My car is also not doing that great, and I think that I am going to have to pay for some repairs on the car genuinely soon, so I shouldn’t pay on a modern air purifier. I am just hoping that my air cleaner will last quite a bit longer even though it is seasoned and is making some crazy noises. My air cleaner may be ancient, however it is a pretty great brand. It honestly is supposed to last a pretty long time, but I am not sure that it is going to. If this air cleaner dies on me, I might just cry. I easily do care about having an air purifier during these times when the virus is spreading like crazy.
