My uncle is storing seasoned dirty air filters

I always wonder what drives a person to be a hoarder. It’s just something I don’t get and it’s just truly weird to keep buying things or getting free things and never using them. I know sometimes they do use them however how often? Like, I see on cable some people hoard seasoned newspapers. I just wonder why, why would be something someone would hold onto? My uncle is one of those people, then going to his condo isn’t the greatest thing in the world. It’s like walking through a maze and if you drop something, most likely you will lose it for the rest of your life. I’m not kidding, it will be gone because it’s that exhausting there, then he keeps everything, seasoned automobile tires in the garage, newspapers, seasoned cereal boxes, and for some weird reason, dirty seasoned air filters. These air filters haven’t been used in years. The thing is that he doesn’t even change his air filters. He has the Heating plus Air Conditioning business send out an Heating plus Air Conditioning tech to change them for him. I feel exhausting for the person that has to come to the condo and perform that task. I tried talking to my uncle about it one morning however he just said that he likes to collect things. This isn’t a collection, this is a mess of all sorts and it’s disgusting. I never told him that however that’s what I think. I try not to go to his condo often because it’s just not sanitary. There might be rats or whatever hiding in the mess he has.
