Where is the air recirculation inlet point?

Quick question hopefully - where is the air recirculation inlet point/s in an LS430?  I'm about to use an air-con cleaner and want to fire it in the best place :)

I've done my LS400 a few times with the aerosol type, I put the AC on recirculate and max cold, open all the vents fully and set it off sat on top of the transmission tunnel in the rear. Don't worry it will get sucked in and reach the right places.

I've never used one before.  Presumably you think they make a difference as you've used a few times, - how do you rate them in terms of longevity?

I use one once a year.

I think it goes behind the front passenger seat - with that seat as far forward as poss.

I think the car fills up, so just follow the instructions on the can and all will be well!

On my car (Not a LS), I do it where the pollen/cabin filter is, and remove the bottom plastic and place it directly underneath it, it goes straight to the pollen filter and recirculates throughout the system.

It certainly makes the car smell nice once done but that soon disappears, never had an unpleasant odours fro the AC although I do leave it on all the time so this may help, for what it costs it can't hurt to do it every 12 months..
