Great value and quality
Size: CF11182&CA12050
Perfect fit for turbo Civic- appears well made. I had an issue with another Honda about 4 days after I changed this and paid $28 for JUST a cabin air filter at an auto parts store. Apparently- mice like to get in there

It's a Filter!
Size: 97133L1000&28113AA100
Fit great! Just look on youtube how to put in! I'm not in a particularly dusty area, but the air cabin filter was a disaster after only a year. Will buy again!

Easy
Size: CF11966&CA12166
Perfect fit. Easy to install. Good price. When changing the cabin filter the screw removal is a little easier if you notch out the plastic in front of it. Its behind the glove box and is not noticeable.
