Climate Control Air Filter

Several people have installed the charcoal versions.

I have mentioned in other threads that one needs to be careful about assuming that a filter that traps the most particles is the best for your system. That applies to home HVAC also.

The problem is that it "could" in some cases cause the fan to work harder, possibly causing the fan to fail, or could reduce the effectiveness of the system (especially cooling). The same is true of any filter that is too dirty. It's not a clear cut case either way, but something to consider.

I would rather use a regular filter and change it twice as often, rather than getting an expensive filter that may restrict air flow even when new out of the box.

For the same reasons, most home HVAC professionals warn against using the most restrictive and expensive home filters in their systems.

I now really agree with this statement. I replaced my filter with one from PotAuto (carbon). I immediately noticed the car wasn't cooling as efficiently as with the OEM filter. The difference was really noticeable returning to the car after it being parked in the sun for an hour. The car did not cool down within the 3 minutes it used to take. Yes, it was installed correctly with the arrow pointing down.

So, I went to the Stealership and overpaid for an OEM filter and replaced the PotAuto. The HVAC is now running like it used to.

One thing I noticed is the PotAuto filter weighs 7 ounces and the OEM filter weighs 2 ounces. So all that extra weight/density was probably restricting airflow, providing less cooling.

Now I just need a place where I can find OEM filters at a reasonable price.

I have extra air filtration on my home HVAC system. In order to compensate for the better filters, I added an additional return air to compensate for the reduced flow.

The "more restrictive" filters usually sport fancy names and cost many times more than plain vanilla filters.

Use them at your risk on any type of system.

I took my cabin air filter out to check its condition w/o paying attention to the arrow.

The post above says the arrow should point down - is this correct?

Definitely should point down on 1G (2009-2014) so I assume same for 2G.

The cheap ones are the same as the OEM ones. It's the expensive ones that overdo the filtration and cause poor performance. This is all you need. By the way, the gen 1 filters are the same as I still have those and use them in the Gen2. http://www.ebay.com/itm/C36067-High...0312714&pid=100005&rk=3&rkt=6&sd=111943787929

Just ordered two. I could actually order 3 or 4 for the same price for one at the Stealership. THANKS!

I have not looked at the Genesis yet, but the airflow direction was molded on the plastic snap-on cover on my 2012 Sonata.
