Can you also use this stuff on cabin and hvac filters too?

I believe that as long as the filter makeup uses the oil this was designed to clean. but read up on the internal makeup of the filter- and see if this is an option in the manual for the filters you are using. if so the manual should say that it's cleanable via this stuff... VsM

Can this cleaner be used on K & N home air filters?

The red looking oil is only for car engine air filters. Home ones don't get oiled. You just rinse them out every 60-90 days to clean them, and let them dry before reinstalling

Can i buy the spray nozzle separate?

Never seen just the nozzle for sale.
