Noisy dehumidifier starting to get to me

Although most central air conditioners are more than capable to dehumidify indoor air to a level that is satisfactory to most people, others like myself that suffer from extreme asthma and allergies, it just doesn’t cut it by itself.  That’s why I started to look into buying a dehumidifier to add inside my living room to cut down on the moisture inside my house. It’s not that my air conditioner is totally incapable of cutting out moisture, I just want dryer indoor air even when the AC isn’t running.  I ended up buying this great dehumidifier that is rated to take 70 pints of water out of your air daily. That’s a huge chunk to add to what is already removed by the AC! Although it isn’t free to run this with my house’s electricity, it isn’t as much as many would think either.  All in all, it was a great investment, until after a year and a half of daily use, it has start to make a large rattling sound. After the sound grew in volume more and more, I did some research online ad found out that this particular brand of dehumidifier starts to rattle in the plastic frame of the device after so much repeat use.  It’s basically inevitable, apparently. Granted, it still performs well, but the noise is getting out of hand, so I’m not looking at buying dehumidifying devices that attach to central air conditioners. Perhaps that will be a better solution for my moisture problem, although I am not convinced that I need to just move to the dry desert at this point.
