^^^ while not as adamant as you I also believe changing the cabin filter to be somewhat a non-issue. Never done in in our '07 Prius which we got new, never on my '13 Leaf new and never on my '12 Leaf used in '16?? from CA. Of course not living on a gravel road and in a pretty clean city I also rarely change the air filter(on ICEs) I probably take it out every other year, knock any leaves or debris off it, hold it up to the sun and if I can see through it, I put it back
I think I've changed the air filter once on the '07 Prius and it still gets 50MPG on the road
I still change the oil(and filter) regularly, at 5k when I used to do 3k but most other things I wait until they become an issue. I've heard you can go every other time on the oil filter but as they are very cheap($1.99 on sale) and I tend to only change yearly because we don't drive a lot, I do both the oil and filter at the same time. Besides as long as the car is up on the ramp and the airflow plastic piece is removed, changing the filter also only takes a couple of minutes extra, the bitch is driving the car up on the ramp and trying extremely hard to not drive off the end
never done it but I worry about it a lot every time I do!
Oh, speaking of air filters, I also rarely change our house air filter. It's one of the new 5" thick pleated jobs and costs $25 a pop. A couple of times/year(generally when the furnace gives me a "change filter" warning on the thermostat) I take it out, use my air compressor and thoroughly blow compressed air through it(of course outside) hold it up to the sun and again if I can see lots of light through it, put it back
I think I've changed it twice in the 10 years since we got the new furnace.
I have nothing against people wanting to change air filters more often, it's just I've been taught if you can see light through it and nothing looks ripped or damaged, it's just a waste of our natural resources(and money) to replace something that probably doesn't need it. Now if you have allergies or can really tell a difference when you change the filter more often, go for it, they don't cost all that much
