    The first I came across was in the 2005 JB KIA Rio - that's the one I asked to see when it was being replaced - filthy.

    I'd had a couple of older cars which we removed the A/C Evaporator - the build-up of dirt, dust and odd stuff I suspect was grass seeds etc makes me happy to have a filter.

    Does anyone know if the filter is before or after the heater/a/c block on PRIUS?

    That's a really good question. I hope someone knows.

    Off-topic, but kind of similar: on our house's forced-air central heating, I put in replacement grills on all the return air intakes, that have filters. You're supposed to change them yearly; I was doing that, with the occasional vacuuming within that year. Now I've figured they look about the same as new after vacuuming, I'm stretching the year interval. Anyway, between the introduction of those filter, and the sealing campaign I mounted on the all the ductwork: the regular filter at the furnace never gets dirty.

    Keeps your ductwork clean, but now you've got to clean all these filters rather than one.

    Yeah, it's easy though: the grills are hinged. Four in total, maybe 3 times a year.

    The duct system when I first looked into it, was incredibly "porous". Also had some "Escher" elements, ie: unconnected, nonsensical branches.

    I got so tired of being tracked down at the dealership and have to say that I didn't want to change filters. Eventually, I bought a cheap filter from Pep Boys and would change the filter at every oil change just so they would leave me alone. In the parking lot, I would put the better one back right away.

    What are the filter part numbers? Engine and Cabin please. Dense (Toyota) and any others that are actually correct fit?
    Thanks so much!

    lol. Yes it can be filthy in 6 months. Ask me how I know :eek: :cry:. I try to take it out, empty out the loose dust/sand/insects to extend the interval. Some places take a year and some 6 months. It depends on your environment. A place that uses a lot of sand (instead of salt) in the winter can leave a dusty filter (among other contaminants)

    It might be the minimum charge (charge in 1/2 hour intervals).

    I don't wash mine. I'll just knock out the loose dirt and maybe if I have a vacuum handy, I'll vacuum it. Otherwise, I'll change it every 6-12 months depending on how bad it looks.

    I believe you tideland. It just gods country here. :whistle:

    Actually, I think we broke record for rainfall in March, as of today: must keep the dust down

    I recently bought filters online from a dealer. I can check when I get home.

    To add more information to Sooner Al's post:

    The standard Toyota cabin air filter is a "dust & pollen" filter. The "premium charcoal" Toyota version is a particulate filter. Depending on the area you live in, a dust & pollen filter might work well. If you're in an area with a lot of industrial buildings (by area, I don't mean neighbourhood but more like city-size cause pollution does travel a good distance) or a place that uses sand for winter grip or a place that has a higher concentration of diesel vehicles (usually goes hand-in-hand with the industrial buildings but not always), then perhaps consider a particulate filter.

    Here in Canada, the aftermarket ones used to be particulate filters for the same or less price than the OEM dust & pollen filter. Canadian Tire changed their cabin air filter model to FRAM cabin air filter. It works down to 5 micron (particulate filters will work down to at least 2.5 microns which is the size of soot, certain types of dust and allergens).

    The cabin filter on my 2016 looks like a carbon one, so I would assume it is more than a dust filter. I have not checked my new one.

    Stupid typo and no edit. 2017 not 2016.

    I need to verify what I purchased. Since the dealer did not list 2017, I chose 2016 Prius. The new filter is not a carbon filter, so I need to verify the part number. Here are the Toyota parts I got.
    Cabin filter: 87139-28020 Element, Air Refiner
    Air Filter: 17801-21060 Element, Sub-Assembly

    I guess what I'm trying to say: don't be too hasty in ordering filters, they can last.

    Didn't realizing I was intruding on an exclusive fraternity btw.

    Sorry. Your posting appeared right after mine about part numbers. Since your picture appeared to have a part number, I mad a faulty assumption.

    Most of us do not live in the clean country of the north :D

    Well Prodigy mentioned getting engine air filter for his 2017; I couldn't resist.

    The cabin filter does seem to get dirty faster, but not much riding on it.

    The clean air filter is after the inlet control damper but before the blower and evaporator. Both fresh and recirculated air pass through the filter. (See the “Mode Position and Damper Operation” diagram in the air conditioning section of the Repair Manual.)
    Though it says it was updated for 2016, the “Air & Cabin Filter Information” document from Toyota kindly shared by @Sooner Al is out of date, since it lists the same part numbers for all 2010 and later Prius cars; the fourth generation definitely uses different filters.

    The part numbers from @Prodigyplace agree with Toyota’s parts catalog, which says they are common to all fourth-generation (ZVW5# series) Prius cars worldwide. The prices below are U.S. and Japanese list prices.

    Clean Air Filter (Cabin Air Filter)

    As @Tideland Prius notes, Toyota sells two versions of the clean air filter, the original one and a more expensive charcoal-impregnated one. See bulletin T-SB-0142-13, “HVAC Odor Maintenance,” for when to use the latter.
    • 87139-28020 – Filter, Clean Air (Pollen Filter, OE Part) ($20.99, ¥2,000)
    • 87139-58010 – Filter, Clean Air (Deodorant Filter) ($50.15, ¥4,000)
    Aftermarket substitutes:
    Engine Air Filter
    • 17801-21060 – Element Sub-Assy, Air Cleaner Filter ($18.00, ¥2,600)
    Aftermarket substitutes:
    • Nippon Micro Filter Co., Ltd.: A1433
    • Pacific Mfg. Co., Ltd.: PA-1806
    • Toyo Element Industry Co., Ltd.: TO-192
