    Just a quick question for those of you that do their own maintenance. How often do you usually change your air filter?

    Whenever it is really dirty :)

    Seriously, abound here we have major rodent problems, and probably once a year I'll find that a rodent has turned the airbox into a fluff palace in one of the cars. But cleaning all that out and replacing the filter has no noticeable effect on fuel economy. A conservative schedule may be an annual or every 30,000 miles kind of thing, about the same frequency as a cabin air filter change.

    Thanks Seilerts. I seem to have misplaced my service manual atm but 30k miles sounds about right to me (I seldom travel on dirt roads). I think mine's been in for about 23k miles, looks a little dirty but not all that bad. I just changed the oil and oil filter today and was thinking I should also do the air filter soon. Just trying to decide whether to grab one on Monday or schedule it for the next oil change.

    JUST replaced mine approaching 31K. It was a bit dirty. I always read that you should replace when you have trouble seeing light through the filter.

    Well, I drive mostly backcountry dirt roads, and while dust is not much of a problem from Sept. through May, the summer is hellish.

    So, at about 31K I could still see some light, but it was looking a bit gross, so I bit the bullet and spent the $9 at NAPA for an OEM equiv.

    BTW, I have mucho "meece" problem, but the furry little monsters seem to end up partying on the cabin filter. I have replaced the cabin filter I think three times because of "meece" damage. Only had minor evidence of them at the engine filter. Once they left a few Shredded Wheat biscuits in the engine filter box. I DO hate "meeces to pieces."

    Thanks for the info cyberprius, I'll give that "light test" a try. BTW, was that sunlight or just normal indoor light levels that you tested it under?



    Oh I wish I could find an OEM equivalent here. Our dealers here are an amazing rip-off, they charged me $75.00 last time for the OEM filter.:eek:

    I'll have to shop around a bit more and see if I can find one. Maybe that's a good excuse for leaving the filter in there just little bit longer.

    Regarding light through the filter -- this is Oregon USA -- the Pacific NorthWET.

    We get a few hours of unobstructed sunlight about July 31.

    I don't like going into the house with dirty hands, so I have a flashlight I hold behind the filter. If the light shines in, the filter is good. Then comes the "well, I can see the light, but can I see it enough" debate.

    As for Aussie filter prices: Can't you mail order from the USA? Prius filter prices dropped like a rock here in my area in the last year. Cabin Filters were in the $30USD range and now are going for $8USD and change.

    Ok I know what you mean. I'll give it a try.



    I've thought about that a few times but postage and handling usually eats up most of the saving. Also it's really hard to find places that will ship outside the US. We've got some pretty good non-oem alternatives for most cars, but so far I haven't seen one for the Prius air filter (oil filter is no problems though). I'm gonna make some more inquiries on this though and see if I can find something. The non oem parts are usually less than half the price of what the dealers here charge, even when the quality is every bit as good. For example my non oem oil filter is $9.50 whereas the stealers wants $22.00 for the toyota one, and there's no difference I can see in their quality.

    What cars need is a filter restriction gauge. An OEM filter in a car driven on paved roads in an area that isn't particularly dusty can easily last over 50k miles before there is any reason to change it.

    If you ae changing your engine air filter more frequently than necessary you aren't gaining anything but are increasing the possibility of getting dirt in the engine while changing the filter or mis-seating the filter and having a leak.

    If you are using cheap Brand-X filters, they usually don't filter as will as an
    OEM or major brand name filter.

    Thanks Stefano, but notice that they only ship to US and Canada. I might do some more searching on ebay though and see if I can find someone who ships to Australia. Even if I do find one, postage is likely to be $25 or more so looking for a cheaper non oem one here might still be a better option. (that's if I can find one though.)

    Yes but you could contact the sellers and see if they will sell you more than one to save on shipping. May be a good option for you with oil filters you see quite often someone selling a case of oem oil filters for 5 to 6 dollars a piece on ebay maybe at 25 or 30 dollars shipping that still would work out to less than 10 dollars a filter for an oem one.

    You are supposed to inspect every 15k miles, but I just go ahead and change it at that point. My cabin air filter has always been dirtier than the engine one so far.

    Non-paper filters can be washed to enhance longevity if they are not to abused. I generally use Simple Green for the engine filter and soap then Fabreeze for the cabin filter.

    Just buy a furnace filter and cut out the size you need! Hal

    Changed my cabin filter at 20K and my engine filter (today) at 25K. Maintenance schedule says to replace both at 30K. Both filters cost me $50. Cheap insurance.

    Cheap insurance for what? I guess it does help keep the interior clean. What did we do up until the 2000 yrs.?

    I change mine twice a day, at lunch time and when I put the car away at night. It's cheap insurance and fits right in with my 500 miles oil change interval.
