2023 R1S OC LA Silver 21 as of 23xxx Nov 3, 2023 !!
I work for a company that manufactures the equipment that challenges filter media (used by DoE, DoD, for Pharmaceutical Lab compliance, BioSafety cabinets, NIOSH filters, N95, N99, and N100 masks, and so on). A lot of those are regulated and require 100% testing of every filter produced (which is where our equipment comes in). Most even require periodic RE-testing to validate filters continue to perform and don't develop leakage (especially 'Classed' clean rooms).

This thread has piqued my interest, so I'm working with our PhD Applications Engineer to run some tests on available aftermarket filters, and I'll compare them to Rivian's OEM. We should be able to validate whether these are 1- in fact HEPA grade, 2- what the flow rate is THROUGH the filter media (which can be used to somewhat compare pressure drop) and 3- whether there's seal leakage around the edges of the filter (bypassing it, and making it a moot point whether the filters themselves are adequate).

I don't know for a fact (one way or another) if all Automotive filters are tested. I DO know Ford tests theirs--I'd literally met a few of Ford's filtration Engineers when I attended the University of Minnesota's Aerosol and Particulate course 2 summers ago.

The challenge is developing a proper test fixture. So, I'll do that for funsies.

That said, this won't be a fast process. So, don't get excited. Give me about 4-6 weeks to put it all together and I should be able to provide some input.

My up front hesitation is to sort of... take the marketing with a grain of salt. Most VOCs and organics that might be problematic fall within the range that the HEPA grade filter would capture anyway. So activated charcoal is sort of a party trick marketing gimmick in most cases. I'm sure there are exceptions (I don't know everything), but from a marketing standpoint, it doesn't make sense to me. Especially when you consider those HEPA and ULPA grade BIO Lab filters do not include carbon activated filters, because there's no point. And those are meant to capture 100% of potentially problematic CBRNE threats (both from getting IN and from getting OUT).
Really looking forward to your findings. THX

THIS is why I love enthusiast sites! I'm a big fan of learning from subject matter experts in the strange things I find interest in. I appreciate your efforts and look forward to the results. This one hits home as I live in a dusty ag area. We have Valley Fever out here and it's nasty stuff if you haven't heard of it before.

I think this is the same as one from Bestevmod I bought. i tried to install on the gen 2 today, it does not fit.

1) feel slightly smaller than OEM one pulled out.
2) Gen 2 does not have that loading tray like those Gen 1 video.
3) Once the hepa filter is in, it is wobbly and keep falling out the slot

Maybe i am missing something…

Gen 2 uses a different filter than the Gen 1. This filter is for Gen 1 only, as stated on our site. We'll look to add a Gen 2 version soon.

10/22/2024 UPDATE: Despite Rivian parts site saying their filter is not compatible with Gen 2. Rivian service department has confirmed both Gens use the same filter dimensions.

We've also received confirmation from Gen2 customers that our filter fits perfectly in their Gen 2.

Yes, you guys did. Too bad that I bought from another vender before I saw your website. That vendor has 2025 in the description.

We've updated our instruction guide and created a new video to include Gen 1 and Gen 2 instructions in one place.

We recently shared a discount code with our existing newsletter subscribers but in the wake of recent devastating fires we're expanding our 25% off promo to all Rivian Forums readers as well.

Use coupon code FRESH for 25% off all filters (Rivian & Tesla). We've also included our USA Made Evaporator cleaner though I'm waiting on feedback from Rivian service on what their actual recommended procedure is for the R1 lineup. Discount works through Valentines Day.

Available on our site at: https://everyamp.com

Yes, FYI the EV Sportline HEPA filter fits both Gen I and Gen II

Just installed the BestEvMod filter this afternoon. I have a gen 1. The filter is labeled as Gen 1. They also have a Gen 2. Are they the same, I have no idea.
