Ummm, actually, ALWAYS using the recirculate button can cause your A/C system to grow molds and mildew (been there, done that)...leaving it on fresh so the system gets dried out on a regular basis is better for the air quality in your vehicle, especially if you have allergies to these. I use my recirculate button only when I need it, like if I am behind a smoking dumptruck, stuck in close traffic or passing someone mowing their lawn in a dust cloud, etc., but the majority of the time, I leave it on fresh. My 2000 minivan has a good, replaceable air filter, so I imagine that any newer car should have one by now? lol. If I remember right, I can also get an upgraded replacement filter for my van (found it *after* my dh replaced it last time, of course!).
I too would stay away from anything with an ionizer, based on the info I was given when looking for an air cleaner for my bedroom. Plus, both my MIL and my ENT's office have one running all the time, and the smell from them bothers me...
Good luck on the new car! If I wasn't getting an other minivan, I'd want a Toyota Venza! Lol <img src="i/expressions/face-icon-small-wink.gif" border="0"> .
One thing I know I drive the used car salespeople nuts with is this request "I need someone, WHO IS A NONSMOKER, to go and crank the car, get in, turn on the a/c, and smell the vent and let me know if it smells at all like cig smoke". <img src="i/expressions/face-icon-small-tongue.gif" border="0">
