I'm considering ordering a HEPA filter to upgrade the stock on in my new Model 3: Has anyone done it? I've also got an Air Quality Monitor coming to do some testing.
It's not HEPA but apparently better than stock. Australia made and $59 delivered. Cabin Air Filters | Tesla Model 3 Cabin Air Filter Courtesy: @rohan3au has tested. He may be able to answer any questions.
I installed the one from Abstract Ocean and can tell a difference driving in city traffic with diesel cars in front of me. It’s made from a 3M Hepa filter but is nowhere near the thickness or size of the Model S or X biodefense HEPA filters. Best we can do though! HEPA Cabin Air Filters for Model 3 (sold as a pair) “Made as a perfect replacement for the factory filters (p/n 1107681-00-A), these add 3M HEPA filter media and activated carbon to keep the air inside your Model 3 beautifully clean.”
Thanks @Lox24 for bringing this up. My understanding is that it’s HEPA that does the best job of filtering particulates. Another thing to go into that thread about stuff that’s missing from the Model 3. Damn well need HEPA in fire season.
Also keep in mind the S/X have a positive cabin pressure system in addition the the huge HEPA filter. The positive pressure system is what really sets the S/X apart from anything else which of course the 3 can never achieve with a filter replacement. The size of the filter on the S/X is directly related to this as 100% of the new air must be pulled in through the filter. Without this system, that size filter would make no sense. Still an upgraded filter would be better, but just like any other car.
Good article ,Thanks. I can attest to what is says. Driving around in bushfire smoke this week and recirc mode has been doing an excellent job.
Just using the stock filters on the Model 3, this is what the air quality looks like outside and inside today (400+ AQI, Melbourne): PM2.5 of 21 inside and PM2.5 of 222 outside. My house is about 150. Overall, very impressive. I have a HEPA filter on the way and I'll install it and compare. Suspect it will get a lot of use.
@Lox24 thanks for that, great evidence. Can you please confirm that is with recirculating air TURNED OFF?
