My portable air cleaner that I have been using in my study room for a while now is showing signs of cutting down. It keeps turning off at random. Also it is not doing as nice of a task in cleaning the indoor air quality. I find myself having allergic reactions like I used to before I had the portable air cleaner. So what I need to do is go out & buy a brand modern portable air cleaner. They are only one hundred bucks or so for the better ones. I am not going to spend various hundred dollars though on a portable air cleaner. So i just need to find more or less the same one or similar to the portable air cleaner that I have which is starting to go bad. I could too invest thousands of dollars into one of those whole apartment air cleaners, however this is not something that I want to do. I do not have that kind of money to spend anyhow. I do not even have the ability to invest because that would be quite a loan to take out from the bank & with my bad credit I can not see the bank giving me that kind of a loan amount. So I will just have to stick to the portable air cleaners instead which were doing me legitimately nice until this one that I have started acting up! Maybe I will pay a little more here just to have better quality & maybe it would last a longer lifespan than this last portable air cleaner did.
