3rd-Party Tested Tesla Model 3 HEPA Cabin Air Filter Replacement

Described as a life-changer by allergic people — and as a “must have”  by those in areas with pollution and fires,

A Tesla Model 3 HEPA cabin air filter (along with an air freshener) is everything you ever wanted and didn’t know you needed.

Finding actual HEPA-grade products proves challenging, though —

After contacting all the manufacturers, only one product had documentation to back its claims up.

The rest, although still superior to Tesla’s original air filter, may not perform as well as you think.

Let’s quickly see what HEPA standards actually mean — and dive right into the products I suggest you look into.

HEPA Standards: What Manufacturers Don’t Tell You

A HEPA (High-Efficiency Particulate Air) filter, as defined by the U.S. Department of Energy (DOE), must filter out 99.97% of particles sized 0.3 microns or larger to “pass the test.”

For context, pollen is 30 microns, smoke sits at around 1 micron, and bacteria is 0.5 microns on average.

Microns scale spectrum, including particles invisible to the human eye.

Independent lab tests can be performed to certify these standards are met.

Most Tesla Model 3 HEPA cabin air filter replacements being sold, however, don’t bother to do such tests.

Aside from that, manufacturers fail to communicate potential downsides.

For example, Model X & Model S include HEPA filters as standard, but their filters are magnitudes larger than Model 3’s.

With stronger filters, Model 3’s fans may end up running beyond their design specifications.

Certain HEPA filters may also restrict airflow to some extent.

It’s yet unknown whether this has a long-term impact on Model 3’s Heating, Ventilating & Air Conditioning (HVAC) system.

Risks and facts acknowledged, here’s the only manufacturer with proof that their product actually meets some standard.

Best Tesla Model 3 HEPA Cabin Air Filter Replacement: LUFTT

NOTE: This product has been out of stock for weeks. I’m leaving the product details below until I find a documented, third-party test for another manufacturer. Comment below if you know of any!

LUFTT is the only seller that can support its HEPA-grade claims with data.

Although not quite 99.97% of 0.3 microns particles as the DOE suggests,

This product presents a document backing its ability to filter out 99.9% of bacteria (~0.5 microns in size), which is enough to meet international standards.

According to customers, the filter immediately eliminates both inner & outer smells for good.

Empirical proof that air quality improves can be found on Evan Michiels’ YouTube Channel:

Evan has tested many of the products we’ll discuss below.

He does so by measuring the air’s TVOC (Total Volatile Organic Compounds) rating.

For context, quality air is considered TVOC levels below 0.3 mg per cubic meter. 0.3 to 0.5 mg per cubic meter is acceptable.

Here are his empirical results after setting up the air conditioning in recirculate mode for 3 minutes:

  • XTechnor: 0.16 mg per cubic meter.
  • Breathe Easy Cabin Filters: 0.11 mg per cubic meter.
  • LUFTT: 0.001 mg per cubic meter.

Even more data supporting this fact can be found within Amazon reviews themselves.

Case in point: these are HEPA-grade filters.

For the health of your lungs and your loved ones, consider getting these filters today.

As these filter out finer dust and particles, Tesla’s 2 years interval change isn’t appropriate.

The manufacturer recommends 6 to 12 months under regular use.

You may want to consider the lower end of that spectrum if you live in a humid or dense area.

There’s a reason the product has a perfect, 5-star rating — you just can’t find anything wrong with the product.

At least not yet.

For allergic reasons or otherwise, if you’re looking for actual HEPA-grade filters, these are the ones to get.

I’ll discuss alternatives but none of them provide tests to validate whether they meet the standards or not.


Fits: All Model 3 & Y years and trims.

✅ Multiple third-party tests backing its HEPA claims
✅ Eliminates bad inner & outer smells for good
✅ Perfect, 5-star rating

Most Rated Tesla Model 3 HEPA Cabin Air Filter: XTechnor

As I warned earlier, I couldn’t find any technical documentation supporting this seller’s claims (or any other moving forward).

With 700+ ratings and quite a few YouTube reviews, however, it’s hard to argue against these as an OEM upgrade.

Unlike others, this package includes the tools needed to remove the body panels where the air filters are.

Although the installation process may take 15-20 minutes and require body contortions, it isn’t the product’s fault.

Blame Tesla engineers.

Whether in a Model 3 or Model Y, customers haven’t had any noticeable airflow restriction whatsoever.

The product eliminates bad smells, though some customers complain the filter has a peculiar smell of its own when brand new.

These filters may not be certified, but the number of positive reviews confirms customers are happy with the result.

In the end, humans won’t notice whether the product filters 0.3 microns — all we care about is whether it filters out smells and toxic particles at an affordable price.

If that’s what you’re looking for, XTechnor ticks those boxes.


Fits: All Model 3 & Y years and trims.

✅ Most Rated Model 3 HEPA cabin air filter on Amazon
✅ Eliminates bad inner & outer smells for good
✅ Includes installation tools


❌ No third-party tests backing its HEPA claims

Budget Tesla Model 3 HEPA Cabin Air Filter Replacement: BASENOR

Undercutting competitors by half, BASENOR introduces a combo that can really keep toxic smells and particles at bay:

They sell both cabin air and air inlet filters, adding a second filtering layer to the system.

However, when both are used (or even the air inlet filter on its own),

Customers experience considerable airflow restriction.

(For instance, you may need to adjust the fan 2 or 3 levels upward to achieve the previous airflow level.)

Customers are surprised to discover that the filter is sturdier and heavier than competitors, resembling hard plastic rather than thin paper.

Keep in mind that the air inlet filter fits only pre-refresh models (those produced in mid-2020 or earlier), as the refreshed model space for the filter is somewhat smaller.

The rest of the information, you’re already expecting:

  • No tests to verify its HEPA claims
  • The installation process is a bit complex due to the panels that must be removed to replace the filters

Lastly, the cabin filters do help with bad smells.

If that’s the problem you’re after, they’re definitely a worthy consideration.


Fits: All Model 3 & Y years and trims.

✅ Half the price of main competitor
✅ Eliminates bad inner & outer smells for good


❌ No third-party tests backing its HEPA claims

Premium Pick: EVTuning

The most expensive choice of all.

I do like that they include the filter specs — and these are much more believable.

Not quite to the standard, with a “PM0.3 65%” — that is, filter 65% of 0.3-micron particles.

Many Model 3 owners suspect that Abstract Ocean, a popular brand in the spacee, resells this exact product on their website.

In a way, you know they’ve vetted the product — and you can find plenty of reviews of their site although the product may be out of stock.

Given the higher price tag, though, it’s hard to justify purchasing this one compared to others — unless you truly love the brand.

Cheapest Tesla Model 3 HEPA Cabin Air Filter Replacement

Looking for the cheapest option available?

With some decent reviews & happy customers,

This product seems to get the job done  — and it includes the installation tool which is a plus.

But it’s hard to know how long the product will last — or what sort of smells and/or particulates it will filter out.

Try at your own risk.

Alternative & Complementary Products to Consider

Best Value Evaporator Cleaner: Klima Cleaner

As you replace your filters, you’ll have the opportunity to clean the air ducts, which may accumulate a musty smell over the months of use.

This simple foam cleaner will remove such dust easily and quickly —

And it offers more substance and better quality for a better price than its main competitor.

Best Value Torx Screwdrivers Set: AMARTISAN

To remove the body panels covering the air filters, you’ll need a Torx T20 screwdriver.

If you don’t have one already, consider this affordable & quality set.

It includes a set of 12 screwdrivers with magnetic heads — and a chrome vanadium steel with heat treatment that will last for years to come.

Frequent Buyer Concerns

  • Does it consume more energy to flow air through HEPA filters?

That may well be the case. It’s hard to tell for sure.

Be sure that it won’t be enough to drain your battery faster in any significant way —

But whether or not the fans are “forced” and may reduce their lifespan remains a questionable and reasonable risk.

  • How often should I replace my HEPA filter?

although Tesla suggest 2 years as a filter interval change,

Stronger filters will get clogged up faster, and as such, a small interval timeframe is recommended.

The ideal timeframe can vary widely based on the area’s humidity and pollution — as well as the number of miles traveled.

Manufacturers often recommend 6 to 12 months as a general guideline.

  • How do I replace my Tesla Model 3’s cabin air filters?

Tesla has its own Do-It-Yourself online resource. Here’s a direct link to its cabin filter replacement section.

You can also find plenty of video tutorials, like this 5-minute version from Tesla Owners Online:

Our Tesla Model 3 HEPA Cabin Air Filter of Choice

Being the only manufacturer with independent lab tests to support its claims, LUFTT would have been my #1 recommendation.

Since they’re out of stock as of this writing, however,

I’ll second XTechnor which was the most highly rated product of all. (700+ reviews and counting.)

Give them a try to start breathing fresh, clean air on every ride.
