How-to DIY: Replace the Cybertruck HEPA Air Filter

[TarheelCT]

Thanks, will do!

Ran the question through Gemini, here was its response for what its worth.

The Cybertruck Owner’s Manual and technical documentation indicate that while the filtration hardware differs between the trim levels, the core HVAC architecture remains largely shared.

Here is the breakdown of how the $59k All-Wheel Drive (Standard) compares to the Premium/Foundation Series regarding the blower and HEPA capabilities:

1. The Blower Motor
The manual does not list a different part number or technical specification for the blower motor between the Standard AWD and the Premium AWD/Cyberbeast.

• Engineering Logic: Tesla typically standardizes high-cost components like HVAC blowers across a vehicle line to simplify manufacturing.
• Capability: The blower used in the Cybertruck was designed from the start to handle the static pressure required to pull air through a massive HEPA filter (the "Bioweapon Defense Mode" requirement). In the Standard AWD, which comes with a less restrictive basic cabin filter, the blower essentially operates at a higher efficiency margin because it has less resistance to overcome.

2. HEPA Filter Compatibility
You can install a HEPA filter in the Standard AWD model. Even though it ships with a basic pleated filter to hit the $59k price point, the physical housing for the filter is identical across all Cybertruck trims.

• The Difference: The Premium AWD includes the medical-grade HEPA filter and the "Bioweapon Defense Mode" software toggle from the factory.
• Retrofitting: If you buy the OEM HEPA filter from Tesla Service or a high-quality aftermarket equivalent, it will fit into the existing slot under the frunk cowl.
• Software Note: While the hardware will work (cleaning the air effectively), the specific "Bioweapon Defense Mode" icon—which creates positive pressure in the cabin by ramping up the blower—may not be active in your software UI unless Tesla offers it as a digital upgrade. However, simply running the AC on high with a HEPA filter installed achieves roughly 95%+ of the same air-purifying effect.

The Cybertruck has an updraft filter, unlike the downdraft filtration on the Model 3 (and I believe the Model Y). This is a big advantage in that it doesn't get clogged up with larger items that fall through the intake screen.

Last week I thought I noticed the volume of cabin air was a little more subdued than when the truck was new (over 2 years ago) so I pulled out the cabin air filter. I dropped it from about 6" flat on the driveway and a bunch of fine beige dust popped out. A surprising amount. I kept dropping it from 6-12" and more dust kept coming out. It looked like a mixture of pollen and fine dust from summer off-roading. When the amount of dust coming out slowed to a light dusting, I vacuumed it from the intake side (the side with visible activated charcoal) with a soft bristle vacuum brush and re-installed it. I noticed a distinct improvement in the flow of air coming out the vents on any given fan speed.

A couple of days later we were driving the Cybertruck in clean air when we came across an oil burner producing prodigious clouds of blue smoke. We drove right through the plume for about 5-10 seconds. I have a sensitive nose to combustion byproducts and was sure I would pick up at least a faint trace of burnt oil smell through the cabin air filter but, to my surprise, I could detect none, not even a trace. That's with a cabin air filter over two years old! The caveat is that it is very seldom that it is driven in any strong pollution, mostly just dust and pollen. I imagine the carbon in the filter of someone driving in more urban areas would wear out sooner.

I did order a new filter this morning, so I'm ready to install it when the fall rains return. Expected arrival is this Friday! I figure I will use the still well-functioning old filter for the dust from off-roading this summer.

Everyone on this thread already knows that "free" shipping means it's included in the price. There is no need to point out the obvious. No one was misled.

I see you are in Michigan. When you order an air filter from Ford or GM, delivered to your doorstep, is there free shipping (or is that a charge in addition to the advertised price)? When I drove gas vehicles, I always drove to the dealership to pick up the parts. There was no free shipping.

Whatever dude...

I did scan the forum to see if instructions already existed, but I didn't find a video out there. Since I'm about at the 2 year mark - which is the recommended replacement interval BTW - I figured I'd DIY, record a video and see how it goes.



if you don't want to watch, Tesla has written instructions on their web site. If you're coming up on two years, I'd order the filter in advance since they are often out of stock. I ordered mine six months ago and have had it sitting (sealed in its plastic bag) in my garage. As I hit 1% service life on my filter, I figured it was time.

The only tool you might need is a pry/trim removal tool. You can use a wide flathead screwdriver, but I'd wrap the tip in Gorilla tape or something similar so you don't scratch your frunk trim.a

Plenty of YouTube videos made. I bet cybertruck cabin filter is the easiest to replace!

I was just at the service center and they said I needed to change the filter. I have the truck for little over a year and found it ridiculous that I would need to replace it already. I thought they were just trying to make some extra sale as it also said I need to replace wiper when I had already done that a few months ago since the wiper that came with the truck rubber ripped

you can check remaining service life yourself in the mobile app

Be carefully with open the filter door. 2 of the 3 tabs broke off when pressing them down.
I hope the filter cover is covered under the basic vehicle limited warranty.

environmental conditions cause early replacement

filter, obviously dust, dirty air in driving areas
Wiper, if parked for extended time under tree or near where sap, debris, etc gets onto the glass
I had a 2023 MYP, original wipers and filter
No debris or hazards into the vehicle

it’s a pain, but eliminate the conditions
And won’t have to change as often

I just changed my air filter for first time since Sept 2024. I live in dry desert dust area, with dirt roads and have gone offroad a handful of times. I have 2 or 3 filters onhand from trying to use up the Tesla credit for Powershare. It's a relatively simple operation. My CB does not have the finger holes on the frunk back panel that most youtube videos show, so a gentle pry with a flat blade was needed. It also had no bolts on the filter door that some reference.

In order to not break the locking tabs on the filter door, use the technique in the Tesbros video about pulling up on the top part of the latch. Really easy.

The dirt in the filter wasn't terrible, but it was definitely time to replace. I plan on a 12 month schedule from now on.

I believe all parts of the Cybertruck are covered under the manufacturer's warranty (except for the tires). However, the warranty, like any new car warranty, only covers defective parts. It's won't cover parts broken by forcing them into positions past their breaking point.

That means if Tesla decides not to cover broken parts under goodwill, then you will have to pay to replace it.

It's dead easy to remove without breaking the tabs. You would have to lean into them pretty hard to break them.

they take very little pressure to open. maybe if you live in a hot, dry climate and it’s parked outdoors I could see the plastic getting brittle over time. But that’s probably 8-10 years away.
