    Hi All,
    Was looking for an air filter for my 2017 Prius 4 and saw this:

    It is an electrostatic air filter that I suppose would have similar results to the air cleaner button on my 2010 prius.. Which I miss soooo much.

    Has anyone had any experience with these? Are they any good. Looks like a bit of a pain to wire up to where it would look like it belongs.

    I don't have any experience with one, but as the husband of a wife that ends up in hospital every year due to pollen allergies I'm going to research these.

    If i was going to wire it up, I assume the filter is going to go on the normal cabin filter area behind the glovebox? If so, getting power to it is easy. There's a fusebox literally right next to it (on the side of the car just above where the passenger's shin would be. I'd just run an Add-A-Fuse connector from the fuse for the 12V outlet, and take the ground from the metal screw just at the centre top of the footwell. I've done exactly this for power for a dashcam.

    As for making it fit in the filter holder.... Just gotta hope it's smaller than the OEM filter, then 3D print an adaptor.

    The Gen 3 air cleaner ("micro dust and pollen filter") button simply relied on the ordinary pleated cabin filter behind the glove box. Pressing the button would make the system shift from fresh to recirculated air and run the blower on high for three minutes, then go back to whatever the previous settings were. So its function was just to make sure a lot of the air inside the cabin would get passed through the pleated filter quickly.

    Gen 3, in some trim levels, also had an ion generator called "Plasmacluster", which was a separate, unrelated feature. In the trims that have it, it is always on, whenever the HVAC blower is operating. There is a Techstream-accessible option to turn it off, but no control for it on the panel.

    I did not notice a fuse box near the passenger glove compartment!

    This is not something I would want on all the time. That would not be healthy. There would have to be an on switch. That is part of my concern... Haveing stuff look like it belongs.. no aftermarket switches.

    Most people do not have access to a 3d printer... lol.

    I would argue on this one. My 2010 prius had it... you press the button and it is only on for a few minutes...

    OK, bear in mind that everything I said was prefixed with "If I was going to wire it up", so the whole post is about me doing it, hence the confusion with right/left hand drive and 3D printer availability.

    I imagine the fusebox is near the driver's knee where you are. Which would make things very conveniently located for wiring a switch and fit it in any of the spare positions (e.g. if you don't have a HUD, you can use one of the ones down near the driver's knee). However, I'm not sure you'll find an OEM switch that's suitable as I think they're all momentary switches, not toggle switches. You could of course use a latch circuit to make a momentary switch act like a toggle on/off switch, then use any OEM switch you want that fits.

    That being said, do you really need a switch? The 12V outlet is switched with the ignition. Surely you would want the air filtered better while driving? Isn't that the point? What would not be healthy about that other than it collecting more particulate matter exactly when you need it?

    While it's true that most people don't own a 3D printer, there are tons of companies/friends that will 3D print stuff for you, or just make it out of wood or whatever.

    the air cleaner button makes a huge difference with dust ups, diesel fmes, fire smoke an etc., and i would pay for it as an option. but they don't offer it, unfortunately.
    one of the many reasons i'm reluctant to part with my 10 year old car

    It is a nice feature, even though it doesn't rely on any kind of electrostatic filter, just the regular pleated filter behind the glove box.

    right, but it seals out more of the toxic air. what will an electrostatic filter might filter better, but the same amount of outside air will be coming through it.

    still, if it does a better job on pollen and etc., it might be worth a go.

    i would install it temporarily, snaking the wire out through the gaps in the glovebox, and if it doesn't improve air quality, return it if possible.

    Breathing in ozone all the time is harmful to your health. Turning on the unit once in a while would help eliminate odors in the car at the time and also help with the overall smell over time. Having it on all the time would be a bad idea. I have to wonder how you replace the filter.
