Last year I shared pictures of some of the dirtiest air filters I’d seen. There are more.
Here’s a good example of a typical dirty air filter and how much darker it is than a brand new one.
It looks like some paper got sucked into the intake somehow, or an animal dragged it in.
This one’s a little past its prime. Looks like some animal nesting material got caught in it.
A lot of leaves and dirt got caught by this cabin filter. Remember to check yours.
This cabin filter is just about as packed full of dirt as it can hold.
Looks like something’s been living on this cabin air filter for a bit. A very large colletion of various fibers.
New blog posts every Monday and Thursday, plus pictures throughout the week on Facebook, Twitter, and Instagram!
