Cabin Air Filter Moisture Barrier Clip (Bad Smell Fix) for Tesla Model Y and 3

This custom-designed plastic clip installs onto the bottom of your Tesla Model 3 or Model Y cabin air filter to prevent moisture saturation and eliminate foul odors. It is available as a standalone accessory or in bundles with OEM-spec filters and evaporator cleaner to provide a comprehensive solution for a fresh-smelling cabin.

After extensive testing, YouTuber Adam Davenport found that a plastic clip on the bottom of the Tesla Model 3 or Model Y cabin air filter helps keep moisture from saturating the filter and causing that foul rotten egg/vinegar/moldy/cheesy/feet smell! You can read more about how we fixed the bad smell in our personal Teslas here , but the TL;DR version is that evaporator cleaner and new filters get rid of the smelly bacteria and the clip acts as a moisture barrier to keep it from coming back.
