PureFlow HEPA Cabin Air Filter PC99505HX | Fits 2016-2021 Tesla S, Fresh Air

just installed it last week so haven't had chance to fully evaluate its performance. Item arrived earlier than expected. Removing dashboard trim pieces around glove box compartment is straightforward thanks to Youtube videos but not exactly easy or intuitive if it's your first attempt. The musty odor that prompted the replacement after 40K miles is largely gone. Appearance wise, there is no way I could discern any difference from the OEM filter I pulled out. From the look of the debris in the old filter, I probably should have replaced it 3 yrs ago, or on an annual basis. Due to Covid pandemic, I don't drive as much as I used to and traffic is much lighter during commuting so I really can't evaluate how much pollution/traffic fumes the filter is able to block out. Hopefully time will tell & I'll update the review once I accrued enough miles. Much cheaper than Tesla OEM and will be well worth the money as long as I don't have to replace it as often to take into account the labor involved.

Great product will purchase again next time I need to replace.

The filter quality is good and seems to perform well. It would be nice if they had instructions included or online. It is not clear what the proper orientation for the filter is. The size is slightly too small so I added a thick foam tape to seal the gap in order to make it air tight.

The Amazon title states this is a "HEPA" filter. According to the U.S. Dept. of Energy a HEPA filter removes at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm) (NOTE: That is what your Tesla HEPA filter does). Nowhere on the PureFlow website or on the packaging does it state this product is HEPA rated. In fact, it states the product traps 99% of airborne "contaminates" and provides no micron size information. "HEPA" only appears in the title, which is VERY misleading and should be removed by Amazon. You are not buying an actual HEPA filter.

Product fits as described and is easy to install as per the vendor instructions found in internet.However, significant difference compared to OEM product is, the odors (i.e. exhaust gas) reach cabin more distinctively compared to OEM product despite perfect fitting. Maybe that is the compromise when OEM costs 2.5 times more (considered delivery and import fees) considered to aftermarket part.

Used as a retrofit filter for a Tesla S that didn’t come with the “Bioweapon” filter. Easy to do and works great.

works great thanks

Nice product but it doesn't filter the outside odors like the OEM filter did.

The delivery arrived on time and was well packed, when installed the item was exactly as described. Happy to recommend this seller.
