What You Should Know About Your Vehicle Filters
seems like a new filter is added to the list of new
vehicle necessities every day. As it stands today,
you could have:
1. One and maybe two fuel filters
2. An engine oil filter
3. An air filter
4. A crankcase filter
5. A transmission filter
6. A coolant filter (in most diesels)
7. A Canister filter
8. A Breather filter
9. A Cabin filter
The cabin filter is the newest filter and it's job
is to filter the air that is either sucked or pushed
inside your car before you are able to breathe it.
Like many homes in the USA, your home may have air
conditioning, swamp coolers or simply fresh air circulation.
Your car has the same three modes. Air conditioning
is where you re-circulate the air inside your house.
INSIDE air is sucked through a filter, over some cold
coils and sent back into the living quarters of your
home. Your car does the same thing, re-circulating
the air INSIDE your car and that's called MAX A/C
or "Recir A/C" for recirculation.
Swamp coolers or just wet pad coolers cool your house
in a slightly different fashion. Coolers take OUTSIDE
air, cool it and send it into the house. If the house
were air tight, the cooler would be trying to blow
cool air into a pop bottle, so to speak, which all
of us know is difficult, at best. So as most folks
know, you have to open a window or two to get proper
circulation when using a cooler or bringing in outside
air. Your car does the same thing. It brings outside
air through a cabin filter over cold coils and then
blows it into the car. That's called NORM A/C or "Outside
Of course, fresh air circulation mandates you have
a window open to benefit from that mode. And this
air also goes past a cabin filter before it enters
The cabin filter works in either mode, re-circulatory
or outside air and we've been changing quite a few
of them lately. I even changed mine in my truck that
travels back and forth to the ranch and I found a
ton of dirt, mold, grass, twigs, leaves, animal hair
and fur and even a plastic bag in and on my cabin
filter. Some of the ones we've replaced make vacuum
cleaner bags look clean.
So if I were driving my truck and my brother was sitting
in the passenger seat and we just got done working
cows and he was a stinkin', I would turn the air on,
use outside air and open his window a tad. That way
as air entered the truck cab, it would sweep by him
and out his window. This works if your passenger is
smoking or your dog is wet.
If your vehicle is model year 2000 or newer, there's
a good chance it is equipped with a cabin air filter.
You will pay about $95 to replace it, which includes
the labor, depending on your make model and accessibility.
