If you run the fresh air vent when you run the A/C you shouldn't have a problem, or switch to fresh air before you reach your destination.
Needless to say we are both on fresh air ventilation.
For your information the Foul Odor you are getting is not caused by dirty filters, it is caused by Stagnate Water that is not draining from the Evaporator drain hole, The cleaning stuff you buy is Useless to clean with and the Odor will return.
The fact is there is no repair for this Foul Odor and Lexus states that fact, not all vehicle with get that Foul Odor but some vehicle will get it. I know I am a lemon law expert and mechanic with over 40 years hand on experience.
If you want a temporary repair just like the one the dealership offer for over $100 do it or you can do what I do on my customers cars.
Here is what I do, I use 2 oz of bleach in 1 qt of water and spray it into the air vents with the AC on Fan on High and the engine is running, all door open. This will kill the bacteria and give you fresh air for all summer. You must allow all of the bleach smell to exit the vehicle before driving. All fans on high and all door or window open until clear before driving. This does work and cause no harm to any parts.
