car ventilation

[alanregin]

open ba or close yun venilation nyo sa car? what are the advantages and disadvantages?

[ghosthunter]

open: if you need some "fresh air"... like when driving for a long time and the air inside the car gets "stale".

closed: driving in the city, you won't get to smell the exhaust fumes and the smelly pile of garbage you just drove past.

Personally I have my vents set to CLOSED all the time.

same here. tried opening the vent once on my trip from alabang to makati. sa dami ng usok na pumapasok sa oto ko, sinara ko na lang.

disadvantages i can think of:

a) babaho loob ng oto.
b) dudumi ang aircon filter.

[meledson]

Vents are normally closed din. Pero if malapit na sa bahay (Laguna), turn off the aircon and open the windows para sa fresh air.

Me too, my vents are closed all the time.

Funny thing is, car manuals usually recommend that the vents be set to OPEN or Recirc(ulate), and actually state that the vents be closed for a maximum of around 5 minutes.

closed vent all the time when my a/c is on. if i need fresh air or umulan na nag matagal i just open my window/s provided walang sinusundang mausok that way walang alikabok na papasok sa loob.

siguro hindi applicable sa atin ang car manuals na yan.
using La Union - Baguio route my vents are open, tapos bukas bintana pag foggy. sarap kasi feeling yung fog na pumapasok sa loob ng car.

close ventilation all the time in city driving and a/c on. open ventilation lang pag long drive with windows open sa driver and passenger side.

[shadow]

closed all the time, with the quality of our air, I don't see any advantages in opening it...

Here's the catch - when you close the ventilation, it actually does not completely close. Maybe 80% closed or even 90% but never completely 100% closed, to avoid asphyxiation or suffocation from recycled air. This also means you still smell a bit of odor from outside even if it's set to closed, and this also means leaving it closed all the time is perfectly fine since, like I mentioned, it's not really completely closed.

Take note of this for those who love to run the car idling in enclosed spaces, this is very dangerous because even if you close the AC it's not completely closed so exhaust gasses (more importantly, carbon monoxide) can lead to CO poisoning. You're basically inhaling your car's exhaust, but you don't know it, because CO is odorless.

closed din ako...never ko pa ata na try open to? ah 1 time na try kona pala... diko type kaya close ko nalang lagi

When parked outside and the car's interior feels like a pressure cooker due to the heat, I run the aircon at max cooling with the air vents open as outlined in my car's owner's manual. It does help to cool the interior a little faster.

Otherwise, the air vents on my rides are closed.

the vents of my car are closed most of the time. i open them once in a while during long drives out of the city, except when there are trucks, buses, jeepneys, trikes ahead of me that are belching smoke.

or i would roll down the both windows on the right side about 4 inches when the weather is cool to cold, saves on the use of the aircon.

my wife had me purchase an electric fan which can be attached to the louvers of the aircon to help vent the heat out especially if parked under the sun during the day.

don't mind if some think that it makes the car look like a taxi

here's a photo:

closed all the time.

when i had my cleaning done at mang mario's, they did something so when i press the recirculate button, no air comes out of my vents. when i had my next cleaning, sabi nila tinakpan na lang daw nila ng foam yung **** (forgot what's it called) kasi pinapasukan ng ipis/daga. besides mas mabilis daw magdumi pag nakarecirculate.

ginagawa ko na lang when i need "fresh" air, i open the windows for a while.

kaya din advise sa ibang manuals na dapat naka open ung vent is to introduce fresh air into the cabin of the car, and thus reducing the accumulation of Carbon dioxide (CO2) which causes sleepiness (pagkaantok)[this is for long period trips] so from time to time when having a long trips try to introduce fresh air inside (by opening the window).

safe driving everyone . . .

[jansky]

me.. madalas open kasi masarap ung hangin na malamig hehe nway sa baguio ako kaya mas madalas naka open ang window,

[Memphis Raines]

I never thought of this before. I did notice that the knob is always set to CLOSE or Recirculate so it's closed most of the time.

But then if somebody farts inside, all bets off, emergency open agad lahat ng windows!

Patay tayo dyan :outcold:

I know of a friend who, when he's driving and passes gas, locks the window switches so nobody can open their window for ventilation

naku malapit na ang feb 14...alam na ninyo.

On some cars the vents open in 20 min interval, you have to manually close it. reason is to prevent driver and occupants from passing out, literally.
