Yes, you keep recirculating the same stale air around the inside of the vehicle. This can be of significant danger to your passengers if you tend to eat foods that produce copious amounts of flatulence.every time you get in you have to turn the recirc button on. what i am wondering is if there would be anything wrong (harmful) if the recirc button is forced to stay down(on) all the time since i run in that mode 100% of the time
Sounds like some sound advice. But most of my trips are of less than 15 minutes' duration ... that is, my arrival is about when the cabin has reached a pleasantly cool temperature, LOL, so I don't often get to the point of turning the recycle off.If you have allergies. The recirculation feature, is great for keeping outside pollen from entering, the vehicles cabin.
When entering a vehicle, on a really hot day. Roll down the windows. Turn on the AC. Push the recirculaton button to on. Fan speed high. That will relieve a lot of the hot air in the cabin. Close the windows. Run the AC till the air recycle cold. Then turn off recirculation, after cold.
Never use the recirculation, when raining, or snowing. The vehicles windows will fog up.
Ones I have clip to the top of the window (edit)->glass, then sealed with a rubber gasket that came in the kit. I can see how the reviews say they are crap, in their stock configuration they need to be aimed directly at the sun for them to even spin up. I have a large solar panels I stick in the front windshields of our 'outdoor' cars in the winter to keep my batteries topped up, I modified those fans by running wires from the fans directly to a junction box that the big solar panel plugs into. The box has a rheostat to control voltage so I don't fry the fan motors.Unless I'm mistaken, those fans require a window frame. But in any case, owner reviews (on Amazon) pan the devices as practically useless. Single stars abound.
If the smart has an intelligently designed computer, forcing the button to be pushed down all the time won't do anything. When you shut off the car, the computer would turn off re-circ regardless if the button is perma-pressed or not.what everyone has said is the way i do it. all cars i have ever owned recirc always stays on (unless turned of manually). all i was trying to find out was if the recirc button was jammed to stay on all the time would there be any harm to any of the controllers
A 2007 German study on “Toxicity of Parked Motor Vehicle Indoor Air” which specifically tested the health effects of emissions from one new and one three-year-old vehicle exposed to “parked in sunshine” conditions found “no apparent health hazard of parked motor vehicle indoor air”
Like monsanto perhaps?Research results are routinely self-serving, disfavoring the hapless consumer. Just consider how many industries have misguided us by proclaiming their own "safe" findings. Cough, cough.
Well this posting by the American Cancer Society does seem to support that, however keep in mind that the ACS is in the business of Cancer and if we were successful in curing cancer they would be out of work.... perhaps an overly simplistic analysis but I have had this theory mentioned in the past.....If you are saying we are all dying from toxic benzine levels in parked cars, there must be peer reviewed studies to support that. :shrug:
I'm sticking with the folks at Snopes on this one; just another email forwarded without any basis in fact.Although benzene is linked to leukemia, very little research has looked at whether the interior surfaces of cars release dangerous amounts of benzene, and the information that is available does not support the e-mail’s claims.
