Purolator C36067

[parisgrey]

Interesting, but where did you find the specs for that especially the part about it being an electro-static filter and did you find an specifics on the particulate side.

The other oft mentioned filer is the Fram CF 10735 and the fol is all I could find on the specs/features of each ...

FRAM Fresh Breeze Cabin Air Filter CF 10735 :

-With Arm & Hammer® Baking Soda

-Premium Efficiency - Filters 98% of dust, pollen, and other contaminants from 5 microns

-Odor Absorption - Arm & Hammer® baking soda combined with carbon embedded into the filter assist in cleaning outside air flowing through the vehicle's ventilation system.

Purolator C36067:

-Catches microscopic pollutants like soot, smog, and tobacco smoke Activated charcoal eliminates odors and unhealthy gases Particular layer restricts entry of large airborne particles into the A/C system like dust, pollen, mold spores and fungus Multi-Layer Protection Better Breathing for non-allergy and allergy sufferers Clean smelling air.

While the Fram specs are not that specific the TOTAL LACK of any detailed info as to precents, filtering size on the Purolator filter often means that the "lack of specifics tells one those aren't so great!" and maybe things are so great as the generalities want you to believe.

I bought the purolator from Advance Auto and ended up returning it. *SOME* of their applications have the charcoal; the one for the Genny didn't, and it's not clearly labeled on the box as such. It was thicker than stock, yes, but still bright white (ie no charcoal.). Then I ordered the Fram from amazon and that one clearly does have the activated charcoal in it.

Just so it captures bugs, leaves, and cigar butts that happen to bounce their way into the air intake. I've been ordering whatever's cheapest on Amazon with good results.

Last time I had mine changed, there were a lot of pollen trapped in it. Ah, the South-East in the spring!!

Thanks Parisgrey for pointing this out.

You are right, my bad, it has no charcoal, and the box is generic and misleading. But it does possess a larger filter surface area than the OEM filter which means it should be less restrictive and last longer. Electrostatic charging does not last very long--that's a dubious claim at best.

But the Fram filter is a bad joke too--just a different kind. The charcoal is just mixed in with the paper and is not very effective. The charcoal needs to be in a layer. Baking soda is a dubious feature (like electrostatic charging) and it will probably restrict air flow once the media is subjected to moisture and other contaminants.

It seems nowadays that everybody spins. I will go with the one made in Korea at half the price.

Well you have a right to your opinion and mine is IMO baking soda is a well know odor absorber and what is typically used in refrigerators and I would not expect a solid layer of charcoal since that would possibly be too restrictive and both of those are just odor removal methods so anything is obviously better than NOTHING.

Unlike you I don't have a crystal ball that tells me what is subjectively better so I have to go with what can be shown as a fact that is at least a positive to indicate what might be better than something else and for now the Fram has more points for than the Purolator. One thing that would definitely turn me off is false or misleading advertising which it appears the Purolator has won to this point hands down.

As far as cost goes an extra $13 or so every 6 to 9 mos is sure not going to break the bank just like the extra fuel folks burn with the 5.0 over the 3.8 or even the 3.8 AWD option just to have that capability.

Well, this thread went on for 10 pages about dust and G1 owners finding out they had a cabin air filter:

This is the Amazon page for this filter series as it applies to G1 and G2 Genesis sedans, the Equus sedan and probably other cars as well. We are lucky--we get a lot of choices:

The only one I could find NOT made in China is the Purolator if that matters to you (and it could change). The Champion and the Fram are first cousins if not twins. The construction of these filters is different, they are not pleated paper but are molded from a composite of charcoal, paper fiber, and some kind of binder. They are stiffer and heftier.

It was a learning experience.

The Champion and the Fram are not pleated, or is it the Purolator that is not pleated? Doesn't that reduce air flow by having less surface area for the air to pass thru?

I think so--the fix is to change it more often. Water vapor coming off a roadway is usually acidic and could cause a reaction with baking soda. I think that a cabin air filter has similar requirements to the one for the engine. Keep it simple and non-reactive, incorporate as much surface area as possible in the space provided to extend life and ensure that air velocity across the media is kept to a minimum.

But there was a kerfuffle between the OEM filter (one person liked the Purolator) and the Fram on the G1 thread. This thread has been a discussion between the Purolator and Fram. I was fooled by the Purolator filter packaging that showed a charcoal granule layer in the middle of the filter--there is no charcoal layer. An activated charcoal granule layer would soak up odors and VOCs without any chemical reaction. Just guessing, but a filter made like that would be upwards of $40-50 retail.

And while some could say that it's just a cabin air filter, it's your health that is impacted, so it's important. More important than how loud the horn is, or lighted rear door sills.

So when you go shopping, do you drive your car right through the front doors of the store to avoid breathing the outside air?

I use an air-conditioned hazmat suit.

No seriously, i rarely roll down the windows and that's a problem. It's just too hot in Houston. When it's not hot, it's raining. The air in a car is actually worse in quality than the air on a quiet street due to the VOCs coming from the materials in the car. This is especially true for us, since none of our cars are more than a couple years old. According to some environmental scientists, that "new car smell" is deadly. It's gotten better, it's mostly just phthalates now instead of the smorgasbord of monomer gases and other VOCs from the interior of a car made before the 1980s.
When I park my car in the garage, I try to remember to roll the windows down about an inch and let it air out overnight.
For most of us, the worst air we breathe is in office buildings.

Well after reading this I bit the bullet and ordered the Fram CF10735 filter since I'm a big believer in the benefit of activated charcoal and the baking soda just is the proverbial icing on the cake so to speak IMO. Below are two comparative pics of the Fram filter and the stock filter side by side. The stock filter has 50 pleats each with a height of 19mm for a total filter surface area of 50x38mm=1900 and the Fram filter has 33 pleats each with a height of 27mm for a total surface area of 33x54mm=1782. So numberically the Fram is slightly smaller by just over 5% compared to the stock. However, as you can clearly see the Fram filter is much, much thicker (probably due to the charcoal layer) and will it's hard to quantify it the stock filter appears to present less open filter area than the stock because of the almost twice the number of pleats where the folded surface presented to the air flow might block more air flow than the Fram. Yes the Fram pleats are thicker at the fold, but looking closely at them it looks like still a lot more air can go thru the pleat fold with the Fram than with the stock since the fold angle is less acute than the stock fold.

Stock on top, Fram on bottom:

Stock on left, Fram on right:

Anyway, I don't know if one is really better than the other, but here in the NE we have a HUGE POLLEN season and I'm extra sensitive to that so if I can improve the air quality even slightly in the car then that's a positive at least for me. Considering I'm driving a $50K auto the extra $10 or so every 6 to 12mo is so far down in the noise for me its a non issue.

The Purolator filter was a non starter for me since one thing that is a deal breaker is false or misleading advertising and glaring lack of obviously important detail about a product.

Thanks for the pix and the math Larry. You've convinced me to try one on the next replacement. It looks more like the Champion in the stock pix on the Amazon site with a much more even distribution of charcoal than the stock pix of the Fram would indicate.

The pleats on the Purolator are almost twice as tall as the OEM and the number of pleats are nearly the same (just guessing), so based on your math, the filter area should be 2x the OEM.
