How often does the air cabin filter over the battery need to be replaced?

 

Just take a look at it and you can tell when it's dirty, kinda like a paper air filter. I order a few of them at a time online (cheap that way), free shipping, and replace when I think it needs it. Of course, a dusty climate, etc. would require replacement more often.

 

Thanks! Where's the cheapest you've found? Ebaymotors?

 

benz recommends every 20,000 or 26,000 depending on your flex services, but as already stated depends on how often you drive and where you live.

 

My service advisor had a good tip.
Shine a light behind it. If you can see through it clearly you can get some more life out of it. Also, does the air inside smell at all? I've vaccumed a few over the years. As already noted your climate has a bigger bearing than the actual mileage.

 

Excellent advise. Thanks guys!

 

I ordered a 2-pack off eBaymotors for $22 shipped. That should cover me til spring I'm assuming. I'm in the southeast, so not alot of dust/sand here.

 

Since I live in Arizona, I have found www.autohausaz.com to be great, but there are other places galore to shop as you know. The cabin filter for my '05C230K is $8.82. Not bad. Just order enough stuff to get free shipping. Their service is really fast too! (I am NOT assoc. w/ them in any way). I buy oil filters, spark plugs, etc. there as well and save a ton doing the work myself. Oh yeah, also fuel filters.

Hope this helps somebody.

 

My TYC air cabin filters came in and it's a good thing. Good grief! I pulled that old thing out and held it up to the sun and couldn't see ANY sunlight through it. It was three times as heavy as the new one too. I cannot believe my cabin didn't reek...lol.

 

A little 'research' at various M-B parts source web sites and at AllDataDIY.com shows that the newest replacement cabin filters for M-B cars are 'charcoal impregnated' for better 'air quality'. What this means is that the 'light test' of trying to shine a light through them will most likely NOT WORK as a test of their status. These also have LESS AIR FLOW CAPACITY than the older paper element filters too.

Be aware of which type of filter you are replacing in your M-B vehicle.
