Help setting up an equation for exponential decay?

The question is:

An industrial filter removes 90% of the particulate matter from the exhaust gases of a furnace. How many filters must the gas pass through in order to remove 99.9% of the particulate matter before releasing the gases?

I think it is 0.01 = 100(0.1)^x but I'm not sure
