The Model 3 uses two cabin air filters in a dual-filter housing behind the glove box. Each filter is roughly the size of a standard rectangular cabin filter, with typical per-filter dimensions in the range of about 8.5–9 inches by 7–9 inches and a thickness around 0.5–1 inch. Exact measurements can vary slightly by year and filter type, so it’s best to verify by measuring the filters you remove or checking the packaging.
Key facts about Model 3 cabin filters
Understanding the setup helps when buying replacements. Tesla equips the Model 3 with two lightweight cabin filters that fit side-by-side in a single housing. You can choose standard or carbon-activated variants, and some markets offer HEPA-style options for enhanced filtration.
Estimated dimensions
Before buying, it’s useful to know approximate sizes to look for in aftermarket options. The dimensions below are typical per-filter ranges for Model 3, noting that actual size may vary slightly by year and supplier.
- Per-filter dimensions: about 8.5–9.0 inches wide (21.6–22.9 cm) and 7.5–8.5 inches tall (19.1–21.6 cm); thickness usually around 0.5–1 inch (1.3–2.5 cm).
- Filter housing: designed to hold two identical rectangular filters side by side behind the glove box.
These ranges cover common aftermarket and OEM replacements. If you want absolute precision, measure the filters you remove or check the packaging for exact specifications.
How to confirm the exact size for your car
To ensure you buy the correct size, confirm by measuring or consulting official documentation for your specific vehicle year.
- Open the glove box and lower it by releasing the dampers on the sides to expose the cabin filter housing.
- Remove the two cabin filters and lay them flat on a table.
- Measure each filter’s width and height with a ruler or tape measure; note thickness as well if possible.
- Check the packaging or the filter itself for the exact dimensions or part numbers, and compare with your measurements.
- If unsure, contact Tesla support or a trusted parts retailer for Model 3 replacements that match your year and trim.
By verifying measurements, you ensure you pick filters that fit properly and maintain optimal airflow and filtration.
Choosing between carbon and non-carbon (and other options)
Model 3 cabin filters are available in several variants. The most common choices are standard (non-carbon) and carbon-activated filters, with some markets offering heavier filtration options.
- Standard (non-carbon): Basic filtration for pollen, dust, and larger particles.
- Carbon-activated: Adds odor and some gas/fume adsorption for improved cabin air quality.
- HEPA-type options: Less common, but marketed in some regions for higher filtration efficiency.
Carbon and HEPA variants can be more effective in urban environments or areas with strong odors or pollution, but may be pricier and sometimes have slightly different fit notes. Always verify compatibility with your year and market.
Buyer’s quick guide
Tips to help you shop confidently for Model 3 cabin filters.
- Remember: Model 3 uses two filters, not a single larger unit.
- Measure or verify per-filter dimensions to ensure a correct fit.
- Decide between standard and carbon-activated based on your needs (odor reduction vs. cost).
With these checks, you can select a compatible pair and complete the replacement smoothly.
Summary
The Model 3 employs two cabin air filters in a single dual housing behind the glove box. Each filter is typically around 8.5–9.0 inches by 7.5–8.5 inches and about 0.5–1 inch thick, though exact sizes vary by year and product. Measure your old filters or check packaging to confirm the precise dimensions, and choose between standard or carbon-activated options based on your filtration needs. Replacing both filters together is common and recommended for best performance.
