Cabin Filter -- really necessary to replace as dealer says?

    I took my 2017 Prime into the dealer for a new Hybrid Water pump and though that was the only work I had them do, on the checklist, they checked "Critical" for the Cabin Air Filter (to replace).

    Now, I've had the car 5.5 years, I park it indoors, and -- unlike 99.99% of everyone else, I almost NEVER use the A/C. I'm not exaggerating. I've used the A/C maybe only 5 times since buying the car. and the heat, maybe twice. Normally I just roll down the windows (I live not far from the ocean). I don't like A/C so I've only used it a handful of times EVER.

    Yet the dealer had it checked not as "yellow" (replace in the future) but "red" (critical to replace now).

    I'll be bringing my Prime into my non-dealer mechanic for a lube & such soon, and was wondering if I should spend the money to have it replaced.

    (1) Can anyone think why it would be so critical when I virtually NEVER use the A/C or heat? Would rolling down the windows and getting outside air into the cabin cause it to go bad so soon?

    (2) How long was it before you replaced your cabin air filter?
    And what if I don't replace it, what are the consequences? As someone who almost NEVER uses the A/C or heat, is it going to matter?

    PS: In doing a search on Ebay for the apparent part # (87139-58010) there are a lot of sellers that say they're selling geniune OEM Toyota parts that are "Interchangable" with the 87139-58010. For instance, the 87139-58010 is about $50 on ebay ($56 at Toyota) but there are a bunch of much cheaper (by half) "Genuine Toyota 87139-0E040, Made in the USA". Can someone confirm is the "87139-0E040" is interchangable with the "87139-58010" or no, or if something's missing? Thanks!


    I'm just wondering if it's the dealer trying to get more $$ or if it somehow is actually bad (and if so, if it really matters if I replace it if I hardly ever use the AC or heat). I'm not at all mechanical so I can't tell myself.

    Thanks!

    I had to replace mine on 2021 PP in less than a year. 9 months to be exact. Mice destroyed it. I had to pick it up at a local NAPA. It was an aftermarket filter, but cost more than OEM parts at $35. Anticipating further repeated damages, I purchased an additional aftermarket filter from Amazon for ~$5/each in a 3 pack. Soon after, I put a hardware cloth to block the mice from accessing the filter. I will probably do not need to buy another cabin filter.

    Even if you use the OEM filter, changing it is one of the easiest maintenance items on the PP. Don't pay anyone to have this done, especially at what a dealer charges.

    BTW, Toyota OEM part#87139-58010
    8713958010 - Cabin Air Filter. AIR REFINER; CLEAN AIR - Genuine Toyota Part
    is for an activated charcoal filter that has enhanced ability to remove order, but none of my PP came with it. All of my PP came with regular filter paper. The Toyota OEM part# 87139-0E040
    871390E040 - Cabin Air Filter. DEODORANT - Genuine Toyota Part
    does not show Prius as a fit. Not sure if they are interchangeable.

    What does the filter look like? Clean, very dirty, or something in between?

    It is easily enough for you to pull it out for inspection or replacement.

    Thanks, I looked online at YouTube videos on how to replace it, looks like something I might be able to do, so picked up the genuine OEM part and will try to swap it out myself.

    We replace ours with carbon-activated ones that removes odors yearly but those OEMs are pricey ($54) so I get them on Amazon...two for like $21...seem to work great. (Fun Driving FD157 Cabin Air Filters.)

    I replace every year. I want to breathe as clean air as possible.
