Cabin Air Filter: "The air filter should be replaced when necessary."

Cabin Air Filter: "The air filter should be replaced when necessary."

Does anyone know if the car will tell you "when necessary" happens? How do you know?

I have not seen a car yet that will tell you that the cabin air filter needs replacing, other than in the Maintenance Schedule usually based on miles. It also depends on whether your car is used in a dudty environment or not. I typically check mine on our ICE cars when I change oil. Now that I do not have to change oil I will probably check it every 6 months or so.

Does anyone know how to get to the cabin filter on the Model 3? It is typically behind the glovebox but since the glovebox is electrically activated I do not see how to drop the glovebox.

The parts diagram seems to imply there are two filters.

The filter is left of the front passenger near the floor I believe. It did not look easy peasy to change. I think that that will be changed by Tesla on the maintence schedule.

Had them changed in my X at 18 Months. They were pretty dirty and needed changing.
Price was super reasonable too.

BMW has a count down to change the air filters.
I got pissed when the dealer said they changed it but only reset my counter. I checked the filter and it was still my old dirty one! So shady!

Possibly irrelevant, but my 2012 Nissan LEAF owner’s manual says the cabin filter (only 1 in the LEAF) is to be changed annually. This is a dealer or a DIY, I do it myself. And after a year with low mileage, it definitely needs to be changed when compared to a new, clean filter. I’m guessing there is no reason why other cabin filters can last longer. I’m also guessing that greater annual mileage and dirtier environments may need more frequent changing.

An air cleaner catches dirt. It will be dirty when you check it. It needs to be replaced when air can no longer be drawn through it effectively, not when it looks dirty.

There is a YouTube showing how to change the Cabin Air Filter. Just search YouTube for Cabin Air Filter. It is easy to do and definitely DIY.

I plan to change mine just like I have done for all of my cars.

Not changing cabin air filters is worse than not changing HVAC filters for your furnace.

For average cars, typical change interval is 15k miles.

YouTube shows where the filters are for DIY.

@sromoda, I agree with you, but how will one know if a dirty filter is or is not effective? And if I’ve gone to the trouble to take out the filter to see its condition, there’s almost no reason to put the old one back. The LEAF filters are pretty cheap...don’t know about the Model 3 filters.

If you see dirty air outlets, your air filter is over due for a change.

Do you think a dirty air filter results in more dirt coming out of air vents? I would think more likely that fans are overstressed and poor airflow would result.

jim.vanzandt | 5 juillet 2019

Yes, dirty air filters would pass less air, not more dirt - unless there's a bypass valve that opens when the filter gets clogged (which I think is typical for oil filters).

Frank99 | 5 juillet 2019

When the filters get clogged, you end up with a higher pressure differential across them (there's a higher vacuum behind the filter). This means that, if there's a crack or gap anywhere, more dirty air will go through the crack/gap, which might lead to more dirt getting deposited on the outgoing air vents.

Parts. Where can I get a filter? Several looks on the web show filters for the S but no mention of the 3. If you did find one, how much?

msmith55 | 6 juillet 2019

The way to check the filter is to look at the clean side, if it shows dirt, the filter needs to be replaced.

wayne | 7 juillet 2019

Does anyone have a guess after how many miles the cabin air filter needs changing? This looks more complicated than I am willing to attempt myself.

How to order? web site has no mechanism

Wayne, I had tires replaced at 29K and upon inspection, the Tesla techs recommended changing the cabin air filter.

RayNLA | 14 février 2020

I changed mine today. It’s relatively easy.
15K miles.

Lonestar10_1999 | 14 février 2020

@RayNLA - I saw the video on DIY filter changing and my impression was that it seemed difficult. You say it was easy. How would you rate your own mechanical aptitude compared with the typical M3 owner?

ksrehman | 14 février 2020

Model 3 owner's manual says replace the filter every 2 years.

SalisburySam | 14 février 2020

I had mobile service replace my filters at about 18 months. The old filters were filthy so glad I had it done

kevin_rf | 14 février 2020

At 17 months and 35,511 miles. Guess I should get around to changing it. Looks like a PITA, thinking a third party HEPA filter.

bill | 14 février 2020

Just had my 2-year scheduled service, which included a cabin air filter replacement. The technician showed me the old filter and said I should have replaced it at the one-year point. I'll replace it annually from here on out.

RayNLA | 15 février 2020

@Lonestar10_1999
My mechanical aptitude is about a 5 out of 10.
If you can install a door knob you can replace your air filters. Just watch a couple of YouTube videos get the proper T20 screw driver and go for it. Its a little bit awkward to access the screw but totally doable.
Be brave!

Take a look at the replacing cabin filters section of https://www.tesla.com/support/do-it-yourself-model-3.

AWDTesla | 15 février 2020

I already replaced mine but I'm on a lot of gravel roads. It was needed

FISHEV | 15 février 2020

Has anyone found an air filter replacement that has activated charcoal?

kevin_rf | 15 février 2020

You mean these?

Nope, don't exist, fake news.
