Query: I hate this humidifier! I miss my one with a filter!

I bought this one because I clean my humidifiers very well and figured I can save some money on filters and just keep it clean.. Well, If I ever try to clean it well, I end up hurting myself trying to get the stuff off of the inside that smells. I cut my self last time. I am going to toss this one and get back my old one with a filter so I can just replace that and clean the parts that need the cleaning... not trying to deep clean it all.
