is there any harm to driving without a cabin air filter?

other than dust particles getting inside the car.

I have an 03 MDX and i cant put a new cabin air filter due to that bar in the way. I was able to force the old one out, it was so dirty it literally looked like it had been burned. So i took that out but cant put a new one back in.

is it okay to drive and use the a/c without a cabin air filter?

I don't think it a good idea. The cabin filter exist for a no. reasons.

Here's a couple:

1. Your health (trust me you don't want to inhale road dust particles). Take a look at your filter and imagine you inhale all those in!!!
2. If debris large enough, goes through it'll destroy the fan unit (fan blades)

You might notice a/c performs better without a filter but I don't think it safe.

Probably it's okay but not recommended.

It's extremely cheap to get a replacement OEM with hondacuraplanet.com or on ebay (generic).

Why sweat it

Yes, cabin air filter is better than none.
Try removing the plastic bar first. The plastic bar is needed before assembly if the dash but not after assembly.
How? See. pollen filter replacement how to

You should not run without the cabin air filter. Not only does it prevent all those particles from being breathed in by you and your passengers, but it also prevents particles from getting into and damaging the fan and ducting mechanisms in your HVAC system.

Trust me - it's a lot easier and less costly to replace the filter with a new element than it is to replace a key component of your HVAC system.

Do yourself a favor - run with the filter in place.

You can run without it. You can run with it. The choice is yours.

AMEN! Does everyone realize that pollen filters did not appear in cars until about 10 years ago?

What do you think happens when you open your window? Does that "toxic" air instantly kill you?

Running without a cabin filter can result in costly a/c condensor repairs down the road if leaves or other debris get in there. The filter serves for more than the comfort of the passengers...

Absolutely no problem what so ever. As you said a little dust can get in. What do you think happens when you drive with the windows down? A lot of dust (and other things) gets in.

I take every opportunity possible to drive with the windows down.

By the way, the proper way to remove the old filter and install a new one is to cut out that bar that is in the way.

I assumed someone would mention this. While you're right, you should consider that at the time during which pollen filters weren't in place, HVAC systems were designed quite differently, and could withstand pollen/dust and other contaminants entering the system without putting significant strain on the components.

These days, HVAC and other systems are much more sophisticated, and built to much tighter tolerances than the cars of a decade ago. Gone are the days of cable-operated vent flaps and diverters; on modern vehicles, these have been replaced with servo motors and vacuum-driven mechanisms. As such, I believe strongly that a $15 filter is a worthwhile investment to help protect said components and avoid costly repairs.

Funny... I still remember my days in the Honda Accord where the wind will blow the leaves thru the A/C unit. Terrible.

I'm sure the filter do catch lots of those nowadays.

Btw, lots of older cars doesn't have it.
