The K&N VF3023 is a washable, reusable cabin air filter sold as a pair for the Tesla Model 3 and Model Y. Instead of a disposable pleated element, it is constructed using a single sheet of non-woven synthetic fabric that has been thermally joined. The media is treated for odor control, and the pair includes filters for both driver and passenger side cabin air inlets.
The case for paying more than a disposable filter is lifetime cost. Because the element is cleaned and re-used rather than replaced, owners avoid repeated filter purchases, and the washable design keeps the cabin filter out of the landfill stream. Warranty terms are reported differently across sources, with one listing citing a 10-year/100,000-mile warranty and another citing a lifetime limited warranty, so confirm current coverage with the manufacturer before purchase. Owners on user forums often point to the filter's odor control as the most noticeable benefit when swapping out a stock filter that has gone musty.
The manufacturer's cabin filter care kit is designed for this purpose: spray on the cleaner, rinse gently, let the filter dry fully, then re-apply the cabin filter treatment before reinstalling.
The VF3023 is sold as a pair, with one filter for each side's cabin air inlet, so the manufacturer's packaging covers both sides of the HVAC intake.
The cabin filter sits behind the dashboard or glove compartment, so check your owner's manual for the exact access panel before starting. The manufacturer describes the swap as a quick job that needs only a few simple hand tools. Plan to remove the glovebox or access cover carefully, note the filter's airflow direction before pulling the old element, and wash the new filters before first installation.
