Is there a light or indicator when to change the filter?

Yes, there is a light indicator that indicates the time to change the filter.

Why does the machine ding several times when it is turned on?

We have two machines and machine does a sort of relay type ding when starts and again if the machine is set to a timer. Not sure if that is what you mean on ding

Do you have any that clean the diesel emissions from the trains in my backyard? My house is 1000 sq ft. I need to clean the entire house. Thanks

You would need filtration of the incoming air at the intake into the house. Portable units such as this one won't do it as they don't filter at the intake.

Does this contain activated carbon granules or an activated carbon sponge?

Carbon filter with carbon pellets.
