If the filter is clogged, damaged or doesn't allow air through then you'll notice loss of power or jerkiness because of incorrect air/fuel mixture. Your fuel usage will shoot up as well.
If none of those 2 signs produce in the next few days then you're all good, nothing to worry about.'
You can always remove the air filter, inspect it and re-fit it for peace of mind. They're a bit tough and can take a few knocks since it's job is just to filter out large particles from the air before sending it onwards to be burned along with fuel.
